We start our second article on our coverage at CEDIA 2004 focusing on Video products and move into Audio components for the serious audio and video consumer.
While Blu-Ray and HD DVD are still a year away (at least), several manufacturers are upgrading their DVD players to output 720p and 1080i signals that take advantage of the progressive scan circuitry found on all new HDTV display products. While not true HD because the signal is upconverted, image quality is certainly improved over other progressive scan DVD players on the market. However, there is one caveat that everyone should take into consideration, which is that you must use a DVI or HDMI digital video connector only to pass the digital video signal. Component video will not pass the upgraded or upconverted digital video signals to your HD display device. Many of these models that offer upconverted video signals are also universal players, which means that they can play both DVD-Audio and SACD.
Another DVD product category that is exploding is DVD Recorders. Several manufacturers are now emphasizing these products over standard stand-alone DVD players. And many of those manufacturers, e.g. Panasonic, for example, are also including hard-disc recording capabilities into their DVD Recorder products. However, if you are in the market for a DVD Recorder with PVR capability, make sure that the model that you chose includes its own electronic program guide as this will easily facilitate the recording of your favorite shows.
As well, DVD/VCR Combos have become quite popular with the manufactures as price points drop well under $200 for a model that includes a 4-head HiFi VCR and a progressive scan DVD player. While sales of stand-alone VCRs continue to drop precipitously, sales of the DVD/VCR Combo are on the rise. Since there is a large installed base of VCRs, a combination unit makes perfect sense for many people.
Lastly, DVD Home Theater Systems, or DVD Home Theater in a Box (HTiB), are now offered by virtually all manufacturers. Several of these models like Sony?s Dream Systems include an all-in-one DVD receiver and slim speakers. While some folks may scoff at these systems, there are some higher-end models from companies like Boston Acoustics, Denon, Panasonic, and Yamaha among others that are among the best we?ve seen and are quite decent. However, remember that the speakers are always the weakest link with any HTiB.

EchoStar plans on offering later this year an interesting integrated LCD HDTV Package. Reportedly, DISH Network was quite successful in 2003 with the lowest-priced bundled DISH Network HDTV systems that included either a 34-in. CRT or a 40-in. rear projection TV with an HD Satellite receiver. For late 2004, DISH Network will be offering a bundled flat-panel LCD HDTV system, which includes their DISH 811 HD Satellite TV receiver (that also includes an ATSC over-the-air HD tuner) and a choice of either a 30-in. LCDTV ($1,999) or a 40-in. LCD TV (@ $3,999). Both displays support full-blown 1080i screen resolution in a widescreen 16:9 aspect ratio.
