CableCARDs and HDTV
An anonymous reader writes: "HDTV is the next big thing. I attended the NAB conference in Las Vegas last week and everyone was pitching HDTV or asking about it. DesignTechnica has an interesting article on CableCARDS, which allows viewing HDTV through a CableCARD compatible HDTV set without needing a set top box. Cable companies are required to enable CableCARDs with card-compatible HDTVs by July 1, 2004. So here's some questions: Has anyone heard of CableCARD? Is anyone planning on buying a CableCARD compatible TV? How many people actually get HDTV in their area, and how many channels? HDTV is so hyped right now but seems that there is barely any deployment."
I sort of have the opposite view. I think TVs should do one job, and one job only - display whatever is input to them (in fact, I think they should not have speakers either). Decoding of digital cable content (and in fact, tuning analog cable channels) should not be the job of the TV. TVs should have one single input (like a DVI port, or something to keep the image digital). Everyone should also have an A/V receiver so they can plug all their equipment into one central source - perhaps there could be a market for cheap stereo receivers, for those who don't need 5.1 dolby digital surround sound. Connections to the A/V receiver should be *fully digital* (maybe then they could have all audio/video data on one line).
Why do I think this is a good idea? Because it is much more simpler, especially for those who aren't inclined or willing to understand how everything works - there's only one connection to the TV, so you obviously plug the video out to the TV - anything else like your DVD player or digital cable terminal plugs into the A/V receiver. There would be no "changing your TV to channel 3 and changing your cable terminal to channel 56" nonsense, which is probably the root of confusion for most consumers. Also, it is much more modular - what if a new cable or satellite technology comes out down the road? Do you really want to buy a new TV? What if a new video techology comes out? What if you need more inputs? What if you want to upgrade your speakers? Upgrade the TV only? The multiple remotes issue could be solved by mandating a standard interface that the A/V receiver uses to communicate with all peripherals. That way, all communications would be between the remote and the A/V receiver, with the receiver controlling functions on other devices such as DVD playback or changing of channels on a digital terminal. The TV could have a power-save function that would turn it off when no signal is detected (or, an interface could be defined so that all A/V receivers would have control over the TV power).
