Forget next month. It’s more fun thinking about what digital toys Apple might be making in five years. Of course, Mr. Jobs’s penchant for secrecy means such predictions are often little more than daydreaming. Just do an Internet search for “Apple” and “mockup” to see photos of products invented by Apple fans.

Forrester Research (FORR) is the latest to look into the crystal ball in a new report that imagines the Apple products of 2013. But rather than predict Apple jet packs or other outlandish new directions, the research firm uses the company’s recent history as a guide to forecasting.

Forrester’s conclusion: While much of Apple’s great successes have been mobile products such as the iPod and the iPhone, the company will seek to colonize rooms throughout the home.

Among the new products Forrester predicts Apple will create are wall-mountable digital picture frames with small high-definition screens and speakers that wirelessly play media, including photos, videos and music, stored on a computer elsewhere in the home. Such products already exist, but Apple could put its own twist on them — for example, by adding its design panache and a touch-sensitive screen that lets viewers flip from image to image with a finger swipe, a la the iPhone.

For the bedroom, Forrester envisions an Apple “clock radio” that pipes in music and other media across a home network. Possible, too, is an “AppleSound” universal remote control, also with a touch-sensitive screen, that lets users browse their music collections and change the songs playing through their stereo as they stroll around the house. This latter technology is already available in primitive form through an application called Signal (www.alloysoft.com) that turns the iPod touch and the iPhone into remote controls for Apple’s iTunes program.

Forrester also thinks Apple could extend into the home the technical assistance currently offered by “Genius Bar” personnel in Apple retail stores. Apple in-home installation services will become especially important as its array of products for the home grows. “The complexity level here can be quite daunting if you have five or six of these different devices,” says J.P. Gownder, one of the Forrester analysts who wrote the report.

An Apple spokeswoman declined to comment on the company’s product plans.

Apple prognosticating is such a popular pastime, in part, because Mr. Jobs has proved so adept at becoming a power broker in markets a Silicon Valley computer company — once known as Apple Computer — has no right to dominate. The iPod remains the top MP3 player, with more than 70% of the market, and Apple is now the top retailer of music in the nation, ahead of Wal-Mart (WMT) Stores. Less than a year after entering the cellphone business with the iPhone, Apple became the second-largest provider of smart phones in the U.S.

That said, the company had an underwhelming foray into the living room with a television set-top device called Apple TV that plays music, photos and movies downloaded from the Internet and PCs on a home network. In an interview earlier this year after dropping the price on the product by $70 to $229, Mr. Jobs said he was disappointed in its sales.

Despite the hiccups, veteran observers of Apple say Mr. Jobs’s intent is clear. “I see everything Steve is doing as positioning himself to take over completely the living room,” says John Seely Brown, a visiting scholar at the University of Southern California and the former director of Xerox’s PARC, the Palo Alto, Calif., research center that inspired some of the innovations of the original Macintosh.

One long-running prediction, proved wrong again and again: that Apple might make a television set. Forrester throws cold water on the idea. Yet some still believe that Apple will one day get into the business as conventional TV makers start to integrate into their sets the ability to surf the Web. Apple already designs computer displays that are as large as some HDTVs.

Steve Wozniak, the co-founder of Apple with Mr. Jobs, says it would make “a lot of sense” for Apple to do a television set that can also access media stored on the Internet and local PCs. “I only started thinking that way recently,” Mr. Wozniak says. “Apple is obviously in the world of delivering display devices already.”

Mr. Brown thinks Apple could simplify the traditional functions on TV sets, like the bewildering electronic programming guides that list the hundreds of channels available to viewers. “Most people find operating high-quality TV systems incredibly awkward,” he says. “They’re as bad as our computer systems.”

There are two models for this legal Internet distribution. Some shows and movies can be purchased or rented from services like Apple’s iTunes or Amazon’s Unbox. You pay a fee for these downloads, which don’t have commercials, and you can keep any videos you buy to watch repeatedly even without an Internet connection.

The other model, common on the Web sites of the TV networks, is free, ad-supported streaming directly within a Web browser. In this approach, you pay nothing, but you have to watch commercials that can’t be skipped. You must be connected to the Internet while watching, and you don’t get to keep the video.

This week, the ad-supported, streaming approach took a big leap forward with the launch of a Hollywood-backed service called Hulu, at hulu.com. Hulu aims to be a legal, one-stop shop for streaming of TV shows and movies from numerous networks and studios. It’s intended as an attractive antidote to pirate sites and to Google’s YouTube service, which has angered the media companies by allowing users to post all or parts of movies and TV shows without permission or payment.

Hulu is a joint effort of two big media conglomerates, NBC Universal and News Corp., each of which operates multiple networks and studios. (News Corp. also owns The Wall Street Journal and the Web sites where this column is published.) But Hulu contains programming from other companies as well, including Sony and Time Warner. All told, it offers full episodes or clips from about 400 TV series, plus 100 feature films.

I’ve been testing Hulu, and I am very impressed with its design and ease of use, and with the fact that it allows users to edit and re-publish its content on their own sites. Despite some drawbacks, it’s the first Web property I’ve seen from mainstream studios or networks that shows a real understanding of both modern Web design and the Internet’s culture of sharing. In my view, it’s far better than the typical network or studio Web site.

Even though Hulu lacks programming from ABC, CBS and many cable networks, it has a fair selection of popular shows, such as “30 Rock,” “The Office,” “The Simpsons,” “Battlestar Galactica” and “Saturday Night Live.” Its movie catalog includes old favorites like “The Usual Suspects,” “The Big Lebowski” and “Sideways.”

The site is organized in a clean, elegant manner. You can browse shows alphabetically, by genre or by network, or you can use an excellent search system. The search system even brings up links to videos of shows on other sites, such as ABC’s “Grey’s Anatomy,” that are missing from Hulu’s own collection.

Watching the material is a pleasure. You can view it in a fixed window or in full-screen view. You can also “pop out” the viewing window so you can place it anywhere on your screen and resize it to your liking. A feature called “lower lights” grays out everything on the computer screen but the video itself.

Even the advertising is relatively painless. TV shows contain just 25% of the commercial time that’s on regular TV. And Hulu allows you, in some cases, to choose the advertisers whose commercials you see, or else to opt to watch a movie trailer at the start of a video in exchange for seeing no further ads during that viewing.

In a break with Hollywood’s past rigidity, Hulu makes it easy to share, even edit, shows and clips. You can repost an entire video, or any portion of it, on your own blog or on social networking sites.

But Hulu also has some major downsides. Most important, Hulu lacks depth. Even with TV series from its owners’ own networks, Hulu typically contains only a small number of full-length episodes, and mainly offers short clips. In some cases, episodes expire after a while. For some shows, such as “Saturday Night Live,” there aren’t any full episodes, only clips. And the wildly popular “American Idol” isn’t in Hulu at all, even though it airs on News Corp.’s Fox network.

This stands in stark contrast to the depth offered on iTunes, where you can find multiple seasons of full episodes of many shows. And it doesn’t begin to compete with pirate sites, where you can find nearly everything.

Also, Hulu requires a decent broadband connection — a speed of at least 1 megabit per second is recommended, and even higher speeds are needed for some content. That means that using Hulu over the slowest DSL lines or cellphone modem cards will likely provide a poor experience.

Another problem is that, unlike iTunes or Amazon Unbox, Hulu can’t be used via a TV set-top box or a portable player. And shows can’t be saved for offline viewing, such as during flights.

Still, Hulu is a good start for Hollywood in finally providing a better experience for Internet streaming of TV and movies. If the service can add a lot more content and make viewing possible in more scenarios, it might strike a real blow against piracy.

There are “universal” remotes that are designed to let you operate multiple electronics devices from a single control. But most universal remotes, if you can figure out how to work them at all, don’t help much with the tedious sequence of button pushes often required to do simple tasks, like watch a movie. In my case, just turning on the TV can require up to six punches on two different remotes, depending on what activity I happened to be doing on my home-theater system the last time I shut it off.

Logitech International, the Swiss computer-accessory maker, has come up with an answer to the problems of remote-control clutter and excessive button-pushing with its family of Harmony universal remote controls that are relatively affordable and easy to use.

The Harmony 1000

I tested two of the latest models of Logitech remotes, the Harmony 890 and 1000, and found that they greatly simplified using my home-theater system, despite a few flaws.

It’s a challenge just getting many universal remotes working, considering all of the electronics gear that occupy many TV rooms. The setup usually involves punching arcane codes into a universal remote corresponding to your electronics devices after looking the numbers up in a manual — a tedious process with lots of opportunity for failure.

Users configure Harmony remotes through what I found to be a far more user-friendly process: by tethering them to a Mac or Windows PC with a USB cable. A software program that comes with the remotes asks users what types of devices they’d like to set up, such as a home-theater receiver, a television set and a digital video recorder. Users will need the model number for their devices.

Once you’ve entered the model numbers into the Harmony program, the software automatically downloads all of the commands required to configure the remote so it works with your TV-room gadgets from an online Logitech database containing more than 200,000 devices — far more than you’d find listed in the manual for a conventionally programmed universal remote control. The Harmony software easily located all of my devices in its database.

An important feature of the Harmony remotes is something called activities, which lets users reduce to one the multiple button pushes typically required to do basic functions with their entertainment systems, such as watching a DVD. Logitech didn’t invent this concept, but it has made the setup process easy enough so users don’t have to hire a professional installer to do it for them, as is the case with many other high-end universal remote controls.

Based on the types of devices I told it I had, the Harmony software on the PC recommended a handful of activities for my remote controls, including “Watch TV,” “Watch a DVD,” and “Listen to CDs.”

To watch a DVD on my entertainment system, I normally need to turn on my TV and set it to the correct video input source, turn on my home theater receiver (which I use to play audio when watching movies) and turn on my Xbox 360 game console (through which I play DVDs) — a process that requires up to seven button pushes on multiple remote controls.

The Harmony remotes eventually allowed me to push one button to turn on all of these devices, but there were hiccups. When I hit the “Watch DVD” activity button, the Harmony remotes initially turned on all of my devices except the Xbox 360. After a few minutes exploring the Harmony software on the PC, I was able to change a setting to correct the problem and update the remote.

In all, it took me about 30 minutes to configure the first Logitech remote I used, the Harmony 1000, and half that time for the Harmony 890, after I had become familiar with the process.

The two models of remotes offered similar functions but in radically different industrial designs. The Harmony 1000 is a tablet-shape control about the size of a small picture frame, with a large touch-sensitive color screen that displays large buttons for accessing activities and other functions on your devices. The Harmony 890 is a more conventional wand-shape remote with a smaller screen.

I preferred the design of the Harmony 890, finding it easier and more natural to use with one hand, not to mention a better value. I have found the Harmony 1000 selling for as low as $272 and the Harmony 890 for $222 on Amazon.com. The 890 comes with a kit that lets you extend the range of the remote by using radio frequency, instead of infrared, signals.

Both Harmony remotes, though, made it much easier for me to use my entertainment system and cleaned up some of the clutter in my living room.

The trouble is, it’s hard to find a DVR that can record in high definition, so most people wind up simply going with the bare-bones high-definition DVR capability built into the set-top box supplied by their cable or satellite service.

But TiVo, the pioneer in digital video recording, has recently entered the high-definition recorder market with a high-end, high-priced product. It’s called the TiVo Series3 HD Digital Media Recorder and it sells for a whopping $800, as much as some HDTVs themselves. And that doesn’t include the $12.95 a month it costs to subscribe to TiVo.

I’ve been testing the new TiVo and I like it a lot, but it’s hard to swallow that huge price, especially since the new Series3 model doesn’t include some nice features available on the much cheaper Series2 version, which doesn’t record in high definition. It also can’t handle certain cable features.

So, why not just stick with the high-definition DVR supplied by the cable company? After all, while it isn’t free, it’s cheaper than the TiVo.

The answer is that, at least in my recent experience with the nation’s biggest cable company, Comcast, the high-definition DVR it supplies is just awful. If cable boxes were sold at retail like consumer-electronics devices, the Comcast DVR I tested, built by Motorola, would get creamed by better competitors.

My Comcast box, a Motorola DCT3412 I, which Comcast rents for about $12 a month, holds a maximum of 15 hours of high-definition programming or 60 hours of standard programming. The TiVo holds up to 35 hours of high-definition programs or up to 300 hours of standard.

Also, the user interface on the Comcast box is crude and confusing — nothing like the elegant interfaces people have become used to on their personal computers and devices like iPods. The TiVo interface, by contrast, is effective and attractive.

The worst problem is that the Comcast box flubs the basic functions of a DVR. It is maddeningly slow at responding to commands sent by the remote control to pause, play, fast-forward and rewind. You press pause and nothing happens. So you press it again. You try to return to normal speed after fast-forwarding through commercials and the unit takes so long to obey your command that you badly overshoot the resumption of the program.

This latency problem didn’t affect just one dud of a Motorola box. In our home, we have four of these units, and three have the problem. All, of course, share the capacity limitations and user-interface problems.

In the program grid, even on a 50-inch, high-definition screen with acres of room, the Comcast box displays just four rows of stations at a time. Until recently, there was a fifth row, but now that has been replaced by an ad. The ad not only sucks up space, but also is aggravating because it gets selected each time you reach the bottom of the grid screen.

Advertising is fine, but in this case, sacrificing 20% of an already paltry information screen for an ad just shows contempt for users.

By contrast, the basic TiVo grid shows eight rows of stations at a time, and offers an alternate view that packs in even more information using two vertical columns: one displaying stations and the other showing a list of shows scheduled in the coming hours.

And, unlike the Comcast box, the TiVo Series3 can be programmed from a Web site, so if somebody at the office tells you about a great show, you can tell the TiVo to record it long before you get home. The new TiVo can also play music and display photos that are stored on Windows and Macintosh PCs on your home network. The Comcast box can’t.

But the TiVo also has some downsides. Unlike older TiVos, it’s intended to replace, not complement, a cable box. So, installing it requires a visit from cable-company technicians to install gadgets called cable cards that plug into the back of the TiVo. In my case, that process took over two hours. Even worse, these cable cards don’t support Comcast’s on-demand feature, which allows you to see certain programs and movies whenever you choose.

And the new Series3 lacks the capability of cheaper TiVos to let you transfer recorded shows to computers and portable devices.

Also, unlike the Comcast box, the TiVo doesn’t have a filtered grid display showing only high-definition shows, which is handy once you become addicted to HD.

Fortunately, it may be possible to get some, but not all, of TiVo’s superior features by just waiting. In 2007, Comcast and TiVo expect to roll out an option for downloading TiVo software to Comcast boxes. This would provide the TiVo interface without sacrificing Comcast features such as on demand. The pricing and details haven’t been announced. Comcast is also working on other new user interfaces and features using non-TiVo technology.

But, for now, the choice is tough. The Comcast high-definition DVR is a cheaper, but flawed product and the TiVo Series3 is an excellent, but overpriced one.

This year, that tower of babble is higher than ever, as new terms have come into being, and old ones have come to the fore. So, here’s a quick glossary of some of the current techno terms you may encounter when shopping for a computer, television, digital camera or cellphone this holiday season.

Aero: This is the graphical user interface that’s a key part of Microsoft’s new Windows Vista operating system, due out around Jan. 30. If you want to get the full benefit of Vista, make sure any Windows PC you buy this season is capable of running Aero. Many are not.

Antiblur: Also known as antishake or image stabilization, this is a crucial feature of digital cameras today. Because few cameras have optical viewfinders, users tend to hold them at arm’s length to frame the shot on the LCD screen. This increases the likelihood of shaking the camera. An anti-blur feature can correct that. The best antiblur technology is optical. Digital versions are less effective.

Draft N: This is a new, faster, longer-range version of the popular Wi-Fi wireless networking system, and many new Wi-Fi products are built to comply with it. It succeeds the common “G” flavor of Wi-Fi. But, there’s a catch. As the name implies, this technology is based on a draft of the forthcoming new Wi-Fi standard, to be called “N.” And the final standard could be different enough to make Draft N gear outdated in 12 to 18 months.

Dual Boot: A computer that is configured to boot, or to start up, in two different operating systems, depending on which the user chooses at any one time. The most important example of this currently is on Apple’s Macintosh computers, which now can be set up to run either the Mac operating system or Microsoft Windows using Apple’s free dual-boot software, called Boot Camp.

Dual Core: A type of microprocessor — the brain that runs a computer — which packs the equivalent of two processors into a single chip. The best known dual-core processors in consumer computers are Intel’s Core 2 Duo and Core Duo, but rival AMD also makes them. They are a good bet for most people.

Flash Player: A small-capacity digital music player, like Apple’s iPod Nano and Shuffle. These players use flash memory, a type of memory chip that behaves like a small hard disk to store music, photos and videos. Larger players, such as the full-size iPod and the new Microsoft Zune, use actual hard disks, like the ones in computers. Flash memory is also what’s inside the small memory cards used in digital cameras.

HDMI: This acronym, for High-Definition Multimedia Interface, describes a new kind of cable for hooking high-definition TVs to things like cable boxes and DVD players. It provides a high-quality digital feed, and combines both audio and video signals via a single connection. When shopping for an HDTV, make sure it has HDMI connectors on the back.

HSDPA: An awkward name for a new high-speed cellphone network being deployed in the U.S. by Cingular Wireless. Its full name is High Speed Downlink Packet Access, and it’s intended to compete with successful high-speed networks from Verizon and Sprint called EVDO, or Evolution Data Only. All of these new networks allow Internet access at about the speed of a slow home DSL line, which is a big boost for cellphones. If you care about email and Internet access on a phone, and you are using Cingular, get a phone that can handle HSDPA.

Quad Band: A cellphone that handles all four bands, or frequencies, used in various countries by wireless phone companies adhering to a world-wide standard called GSM. Examples are Cingular and T-Mobile in the U.S., and Vodafone and Orange in Europe. A quad-band phone can be used on any GSM network anywhere, so if you travel overseas a lot, you may want one.

RAW: A file format for digital photographs that is uncompressed and largely unmodified by the camera’s chips, and therefore includes every detail of the color and image. It is prized by professional photographers and serious amateurs, who look for cameras and photo software that can handle the RAW format. But it produces enormous files, so most users should ignore it and stick with the very good, very common compressed photo format, called JPEG or JPG.

Shared Memory: A computer configuration in which the video circuitry lacks its own dedicated memory and must share, or drain off, a portion of the computer’s main memory. This is common in lower-price computers. It’s fine, but it reduces the amount of memory available to the nonvideo functions of the computer, so you may want to add extra memory to a PC of this type.

WAN: Any wide-area network, such as a cellphone network, that can be used to send and receive data. It is distinguished from a LAN, or local area network, such as the wired and wireless networks deployed inside a business or home. Some computer makers use the term for the built-in cellphone modems in their laptops.

Good luck with your gift shopping. Don’t get trapped in the tower of babble.

To find out, my wife, Edie, and I lived for several weeks with a big, beautiful HDTV, the Pioneer Elite PRO-1140HD, lent to us by Pioneer Electronics. It has a 50-inch screen, a long list of features and lists for $5,000, though you can find it for under $4,000 on the Web.

I tested the Pioneer with digital cable service from Comcast, my local cable provider. This service transmits high-definition programs where available and can record them to a digital video recorder (DVR) built into its set-top box. Comcast also has an on-demand feature that allows you to watch certain programs whenever you like.

The test demonstrated why people are so hooked on HDTV. The Pioneer Elite set performed brilliantly and was a joy to watch with HDTV programming. With HDTV, you are not only increasing the size of the picture, but its quality as well. On the Pioneer, colors popped, details I never saw before emerged, and the whole experience was almost cinematic. DVDs looked great, as did content from a computer plugged into the set.

But there is a hitch: Most TV programs aren’t available in HDTV, and these non-HDTV shows can actually look worse on an HDTV set than they do on older, standard TV sets. So do most videotapes. Also, buying a big-screen HDTV carries hidden costs and hassles. You may well need help installing the set. You may also have to switch or upgrade your cable or satellite service, get a new DVD player and buy new furniture.

The Pioneer Elite model I tested happens to be a plasma TV, which is one of the three major types of HDTV sets. It works by stimulating a captive gas with an electrical charge. The other two are LCD, or liquid crystal display, which uses a screen like those on laptop computers; and “microdisplay” sets that project the image onto the screen from the rear of the set, mainly using two technologies: DLP, or digital light processing, and a form of LCD.

Plasma TVs tend to have the blackest blacks and the best ability to be viewed from all angles of a room. Their colors are warm and vivid. And they cost less than LCDs in large sizes. But their screens are more reflective and a bit darker than LCD screens. There is also a slight chance they can suffer “burn-in,” the permanent embedding of an image, like a network logo, if you leave such an image on for a very long time without changing channels.

LCDs are bright, and they are the thinnest and lightest of the HDTVs. But their colors often seem cold and their blacks too gray. Their viewing angles aren’t as good as with plasmas. And in some cases, fast motion can look blurry.

Microdisplay sets typically cost the least, but they are the thickest of the three types. They tend to have limited viewing angles and can display a “rainbow” effect, which causes problems for some people.

Our Comcast service gave us high-definition channels from all the big broadcast networks and some of the major cable ones. We immediately started watching shows like “Grey’s Anatomy,” “Desperate Housewives” and “Heroes” in high definition, and found they were greatly enhanced. Watching the World Series and NFL games was a great experience, with every clump of dirt, bead of sweat and blade of grass looking so much more real.

The Pioneer also did a great job with an Apple Mac Mini computer we plugged into it, displaying family photos and downloaded videos stored on the Mac.

The big downside was that only a small fraction of programming is high definition. At 8 p.m. on Tuesday night this week, there were just 13 high-definition programs available from Comcast, out of more than 230 total. The on-demand service had a smattering of additional high-definition shows and movies.

And standard TV shows on a high-definition set can look awful. They can be fuzzy. They also typically fill only a portion of the wide screen, with big black or gray bands on the sides. You can eliminate the bands using TV features that stretch or zoom the picture, but these modes either cut off too much or distort people so they look unnaturally short and stout.

Also, we ran into plenty of extra costs and hassles. We had to buy new furniture to hold the TV and all the gadgets that attached to it. We had to replace our DirecTV satellite service with Comcast cable, because the trees in our yard blocked the high-definition satellite signal — which is beamed separately from another position in the sky. The Comcast digital service with high-definition costs more than the company’s standard cable service and its DVR holds only 15 hours of high-definition programming versus 60 hours of standard programming.

Despite all these costs and limitations, we were won over by our HDTV test. After returning the test unit, we went out and bought our own HDTV. We decided that in the slow transition to high-definition programming, there’s now enough content to make HDTV worthwhile. And once you get used to high definition, it’s tough to go back to plain old TV.
