Comcast recently compressed its HDTV-signals and now consumers say that the American provider destroyed their picture quality. To fight its competitors Comcast added an extra amount of HD-channels to their packages, but since the introduction many clients say that the picture quality is lower. It seems that some channels show a pixelated image, which definitely shouldn't happen to an HD channel.
An AVS-forum visitor started his own little investigation and compared the picture quality of Verizon with the offered quality of Comcast. The self-proclaimed researcher at AVS' forum calls himself 'Bdftv'. He says that Comcast sends three HDTV signals per qam-channel, where others send two. One qam-signal has a bandwith of 38.8Mbps, which is enough for two HDTV-signals of 19.4Mbps. Because Comcast pushes three channels into one, you only have a bandwith of 12.9Mbps available per channel... This is the main reason for Comcast's recent quality loss.
It's crazy that a company like Comcast chooses quantity over quality. If you've subscribed to Comcast please try to change to Verizon... Or will they make a change quick?
