[FONT="]In digital cable there is no loss of quality while the video is being broadcast. In both DTH and Digital cable there will be signal loss during transmission; it is not something unique to cable. But this does not affect the quality of the video that we see. This is because in digital video broadcasts a certain amount of error correction data is broadcasted along with the video data. Your set top box will use whatever video data and error correction data that it receives to recreate the original video exactly as it was originally broadcasted. Of course this works only up to a certain threshold limit. If the signal loss exceeds this limit you will stop receiving the video completely, at best you will get some completely garbled up video. This is what happens to a DTH during the rains. This also means that digital broadcast is simply not possible through really poor quality cable. In digital video broadcasts there is no need to worry about getting low quality video because of transmission loss, either you get to see the video exactly as it was broadcast or you don’t see anything. So if the video broadcast by your digital cable provider or your DTH provider is good you will get good quality video[/FONT]
I completely agree with you about the signal quality and its results on reception. But Video quality also depends on bandwidth with which each channel is broadcasted. The operators tend to provide some channels with more bandwidth, so this channels are in more good quality. Also operators vary bandwidth of channels depending upon program being broadcasted, like for sports, movies, songs or for some popular program.
The topic of thread is about the video quality of various channels. I believe as fair policy every operator must allocate required bandwidth for every channel on their platform.
