Humax TiVo DVR Satellite Receiver

While the wife and I haven’t quite reached a peace accord on the matter of our abundant remote controls, one source of marital friction has recently been downgraded to a non-issue: When once we clashed over dwindling recording space on our HD DVR, Humax has now given us 250 gigabytes, the most in any TiVo, which is frankly more capacity than we know what to do with. The T2500 TiVo Series2 digital video recorder is the Korean company’s first consumer electronics product marketed in the United States, under their Humax USA brand.Although Humax is a major global manufacturer of satellite set-top boxes,this single-tuner recorder is not a DirecTV receiver, so you must provide it with a signal from either cable or a satellite box.

Blasting the Dish
Unless you’re lucky enough to have a cable or satellite set-top box with an RS-232 serial connection, you’ll need to use the included IR blaster to link the signal source and recorder. After connecting the T2500 to AC power and a phone line, followed by S-video and analog stereo inputs from my standalone Samsung DirecTV receiver and S-video and analog stereo outputs to my TV, I plugged the included blaster cable into the back of the unit, stringing both IR heads over and under my satellite receiver, straddling the point where it receives infrared remote commands.

Next, I followed the onscreen prompts to set up the IR blaster, trying each of the 10 preprogrammed codes for my Samsung box in turn, only one of which worked. One small issue that shouldn’t have been a surprise: The lag time of changing channels through the TiVo was added to the lag time of the DirecTV receiver, which meant that even a simple channel-up or -down took as long as eight seconds.

From there, it was a matter of manually checking off which of the hundreds of available channels I actually received—a tedious, time-consuming process that requires a handy printout of DirecTV channels or a Rain Man–like knowledge of the same. DirecTV makes no secret of their lineups, so why doesn’t TiVo just offer a Total Choice Premiere option for one-click setup? Rather than go through and mark every last one, I eventually took a leap of faith and just accepted all of the channels.

I also switched from dialup to a wireless broadband Internet connection the principal benefit of TiVo Series2 complaint boxes such as this for the necessary TiVo software updates. This not only freed up the phone line, but, more importantly, I noticed that related operations were much quicker this way, often completed in seconds instead of minutes. The Wi-Fi hardware I used the tiny Linksys WUSB12 Wireless-B compact USB adapter, which is included in the short list of supported broadband adapters was also quite stylish. After I quickly configured it on my PC so that my home network would recognize it, I plugged it neatly into the T2500 with the help of the included extension cable, due to the crowded rear-panel real estate.

The T2500 promptly informed me that I needed a system firmware upgrade as a final preparatory step, guiding me through the process onscreen while I did my part with just a few touches of the remote. I successfully made the always-on connection in a couple of minutes.

Dream A Little Stream
One extremely welcome bonus that has precisely nothing to do with traditional DVR operation is the Home Media feature set, which let me stream not transfer, despite the T2500’s awesome storage my computer’s MP3/WMA music and digital photos to this TiVo. I needed to download and install the free TiVo Publisher software on my PC. While locating and importing tracks and particularly images was somewhat inelegant in this new application, once properly loaded, it performed quite enjoyably.

I named my music and photo collections, and I could easily select individual files via onscreen menus. I could play photos as a slideshow, and all pertinent song info is presented as a screensaver, since all of the ID tags are carried over from the PC. In addition, TiVo proactively downloaded an assortment of recent pop-music tracks to my hard drive for free from TiVo partner BestBuy.com, and I was treated to a private exhibition of professional photographs courtesy of Nikon.

To the Net!
Users can schedule recordings online, as the TiVo Website offers the freedom to search TV listings (by title, description, or actor/director, plus an advanced search by category and genre), browse by channel, and set up a Season Pass, specifying recording quality and priority all with the ease of your computer’s mouse and keyboard interface. This is a good idea, since the process mostly involves clicking and dragging. You just need to set up a password-protected account at TiVo.com, and you can even request a confirmation e-mail of successful scheduling, including notification of potential conflicts. If you opt out of the e-mail, such messages still appear on the T2500.

It’s certainly not necessary to connect the T2500 to the Internet to take advantage of TiVo’s Online Scheduling, but it does improve the experience by providing much faster access to your changes as little as one hour before airtime, versus a 36-hour safety buffer if your TiVo still uses dialup. Scheduling directly via the unit itself is still considered the most reliable method. For example, TiVo Online Central sometimes listed programs not available as part of my selected channel lineup, which can lead to potential disappointment.

I poked around the online offerings, saw some new shows I liked, and grabbed them all, even setting up a Season Pass for another series while I was there. Sure enough, scant minutes later, I saw that my To Do List had been properly updated, with specific summaries in my Messages area; later, the T2500 recorded the programs without a hitch. One other major feature of TiVo Series2 is Multi-Room Viewing, the ability to watch content from one TiVo box on another box in a different room, if you have multiple TiVos connected to a wired or wireless home network. Alas, my insistent requests for a dozen T2500s, to properly test the networking, were met with polite stares.

Humaxed Out?
After days of recording around the clock, which led to some embarrassed explanations to my wife as to a couple of my hasty whatever’s on late-night selections (ah, Cinemax) and with TiVo Suggestions left on, I still felt as though I hadn’t made so much as a dent in the 250 GB at my disposal. I was most assuredly never asked to delete anything for the sake of space.

I captured the majority of my recordings at the Best quality setting, although I can’t say that I’m impressed with the image delivered by the T2500: Perhaps owing to the re-encoding of the previously digital satellite picture, compression artifacting was blatant on many soft textures, while blacks, in particular, revealed harsh geometric activity introduced by the encode/decode process. Bright scenes with little movement fared better, even at medium quality often displaying the subtle film like traits of the original program—so the T2500’s performance seems unfortunately tied to the characteristics of the content it records.

The Humax T2500’s true strength surely resides in its roomy hard drive, coupled with its support of the latest TiVo networking features, although a sharper picture would be nice, and component video/digital audio outputs might be worthwhile additions. Perhaps the ideal consumer here might be someone looking to finally take the TiVo plunge for an affordable $699, with up to 302 recordable hours to help him or her celebrate their new found TV independence. Hopefully, that consumer buys popcorn wholesale.

• A nigh-incredible 250-gigabyte hard drive inside • TiVo Series2 hardware runs the latest software for advanced networking features

HD Receiver DirecTV Tuner

Connect to the future of digital TV,Whether we like it or not, digital video connection is the way of the future. Consensus of the producers to grow shows that consumers who have HD-capable displays that only have analog (Y/Pb/Pr or RGB) high-definition connections won’t be left out in the cold, which is good news.

However, while Hollywood may allow legacy equipment to remain in service, they prefer the potential copyright protection that’s available through digital signals. We enthusiasts like the opportunity to pass digital signals directly to the display without stopping along the way for an unnecessary conversion back to an analog signal.

Finally, several manufacturers have come out with new HD-capable DirecTV tuner to accommodate the growing number of displays with digital connections.

Sony, Zenith, and Samsung are a few of the first manufacturers to introduce HD DBS receiver that are outfitted with a DVI connection that has HDCP (high-bandwidth digital content protection).

These tuners can connect to the new crop of HD-capable displays that have the same input. The DVI interface allows the tuner to uncompress the compressed high-def signal and send it, along with the tuner’s interactive onscreen graphic, to the digital display while it’s still in digital form.

The only drawback is that the signal’s wide bandwidth makes it impossible for you to use any known consumer or professional recording device to make even an authorized recording. None of these tuners offers an IEEE 1394 connection, which would pass along a compressed digital signal that you can then record on a video hard drive, a D-VHS player, or an HD-DVD-like device.

All three tuners offer a complete suite of the necessary inputs and outputs. The Sony SAT-HD200 and Zenith HD-SAT520 are nearly identical; both are built around the same LG (Lucky Goldstar, Zenith’s parent company) chassis and therefore have the same connections.

I’ll refer to them as one unit, except where there are noted differences. Although it has similar outputs, the Samsung SIR-TS160 tuner, sourced from Hughes, has a different back-panel arrangement. We didn’t have a Hughes unit on hand for direct comparison.

All three tuners offer two basic A/V outputs, an S-video connection, component (Y/Pb/Pr) and RGB connections, a DVI jack, an RF-modulated output, digital audio, and other typical satellite connections. Sony and Zenith use an optical digital audio output, while Samsung offers a coaxial digital connection.

All three tuners include a switch that activates either the Y/Pb/Pr output or both the RGB and DVI outputs, but not all three outputs at once. Like many HD DBS receiver, the Sony and Zenith tuners force you to choose either the standard (composite or S-video) or high-def (Y/Pb/Pr or RGB and DVI) output.

You can’t send the DVI signal to your home theater  HD monitor and the composite signal to the NTSC set in your bedroom at the same time. The Samsung receiver, however, does and will always output a 480i signal from the composite and S-video outputs, which makes it extremely flexible for multiroom viewing (make sure that the displays all have the same aspect ratio) or for use with a standalone TiVo or ReplayTV hard-drive recorder.

The process of selecting the type of output is considerably different between boxes. With the Sony and Zenith models, you use a button on the front panel to select your output options. Sony adds this function to the remote for convenience.

The Samsung tuner’s only option is another back-panel switch that offers 1080i, 720p, or 480p/480i options. The switch’s location makes any kind of native output impossible but also keeps curious fingers from changing the setting.

Depending on which mode you pick, the receiver up- or down converts all signals to that output rate and activates the appropriate connectors. While this is simple and entirely appropriate for the vast majority of displays, the Sony and Zenith models add four additional output options, including native, hybrid 1, hybrid 2, and EZ DVI.

The native setting converts 480i signals to 480p and passes along 720p and 1080i signals directly to the display without conversion. The hybrid 1 and 2 settings are similar, but hybrid 1 converts all HD signals to 1080i, and hybrid 2 converts them to 720p. EZ DVI automatically detects the monitor type and converts all signals accordingly. Enthusiasts with multiscan displays (read: CRT projectors) may appreciate these tuner’ added flexibility.

All three units’ ergonomics are effective and intuitive, but the Sony and Zenith units have a slight edge. All of the remote controls are reasonably well laid out and provide proper controls within single-digit reach. Menu structures are attractive and reasonably intuitive.All three tuners eliminate my pet peeve about first-generation set-top boxes: They list analog and digital off-air broadcasts and satellite channel in the same channel list. No more switching inputs.

The Sony and Zenith models benefit from a front-panel display that indicates the current format setting and channel number, which is extremely handy. Samsung’s front panel has nothing more than a hard-to-see red light to let you know that it’s on. The latter tuner does add features like a Biorhythm chart and simple video games for kids.

I’m not sure why you’d need a Biorhythm chart, but the games are mildly amusing when there’s nothing worth watching on TV, which is a common occurrence. All three tuner allow you to select your display’s aspect ratio and modify formats that don’t otherwise fit. However, while each tuner strips gray bars into the unused space beside 4:3 images on a 16:9 screen (to prevent uneven phosphor wear on CRT or plasma displays), only the Sony and Zenith units provide a setting that eliminates the bars permanently.

These two tuners also offer an on screen feature that indicates when a particular satellite program is broadcast in true high definition. This indicator didn’t light up when I watched Joe Somebody on HBO’s HDTV channel.Presumably,HBO upconverted the program before they broadcasted it, but you could have fooled me.

The major differences between the Zenith and Sony tuners lie with the remote controls, although Sony does include a free DVI cable (worth $20). Sony’s remote, as I mentioned, can change the output-format option on the fly. You may not need this function beyond initial setup, though. You can also code the remote for a particular receiver, if you have more than one.

Unfortunately, none of the remotes provides discrete power-on and -off commands or aspect-ratio settings, which might make it difficult to program a macro-based remote control like the Philips Pronto or an automation system from Crestron or AMX.

I connected each box’s component high-def output to an Extron switcher, which was connected to our reference Runco DTV-991 CRT projector. According to signals from our HD test generator, the DTV-991 is capable of a full 1,920:1080i resolution. I made direct comparisons of the tuners’ signals by switching inputs and comparing the image quality. All three tuners looked excellent.

The Samsung’s picture was slightly more flushed than that of the other two tuners and seemed to make colors bloom somewhat. The Sony and Zenith tuners, which created identical pictures, provided a slightly sharper picture than the Samsung. This perceived detail may be due to the fact that these tuners have less color. Unfortunately, we have no way to know which box is accurate, although I’d venture to guess that all three tuners hover on either side of the line. In most cases, you can adjust the color level to some extent through your display.

When I used each tuner’s DVI connection with the Sharp XV-Z10000U projector, I noticed a slight increase in detail and clarity over the analog connection. Differences between tuners were even more difficult to see.

Comparing analog audio levels is considerably more difficult without a reference level, and comparing digital outputs is harder still. If you use an HDTV tuner, you should use the digital output, in which case your external audio processor will mostly determine the audio quality. If you’re using the analog audio outputs (get with the times), all I can say is that the Sony and Zenith models are a hair louder.

Tired of my current, first-generation RCA DTC-100 and its particular ergonomic hang-ups, I’m eager to get a new HD-capable tuner. I’m torn, however, between the options presented here. Samsung’s dual-output capability, which will feed both my main system’s HD-capable projector and its peripheral devices (VCR, PVR, etc.) and a second display, is enticing. For those people who don’t have a CRT projector, this is a good fit. For those who do, the Sony or Zenith tuner native outputs might be more useful, and these tuners’ ergonomic features are an excellent bonus.As the tuners’ street prices are likely to be very similar, choosing one over the other will depend on availability and brand preference.
