HDTV PICTURES DEGRADING

The desire of many television stations to use their new digital broadcast spectrum to offer subchannels alongside their primary high-definition ones is resulting in a significant degradation of their HD picture quality, Broadcasting & Cable reported today (Friday). Until now, local broadcasters have put little effort into the subchannels, but as they begin to proliferate, gain traction, and generate meaningful revenues, HD images are suffering, and the situation is expected to worsen later this year as some stations begin launching mobile services for cellphones and laptops via their digital channels. So far, says B&C, there have been few complaints -- aside from the HD buffs -- about the lower-quality HD images. Viewers, the magazine observed, apparently are really not all that "discerning over picture quality."
