Vchat20Landing is the REAL challengePremium
It all depends on your POV on the matter. I won't say running 2 HD subchannels is going to be the BEST quality, but if you're more about the content and having 'decent' quality, it may be better to run the 2 HD's side by side.
Case in point: My prior mention of the station where I used to live which ran 2 720p channels side by side. In that particular case they ran both CBS and FOX in 720p with a well set up encoder that varied the bitrate constantly depending on which channel needed the bandwidth more at the time. Quality was 'good'. Not great, but good. About U-Verse quality. But the main reason for running both in HD was Fox's (WYFX) primary transmitter at the time was still a low power LD transmitter which did not reach most of their DMA when the digital switchover happened. Since WKBN owns WYFX, they rebroadcasted WYFX on WKBN's transmitter which had ridiculous power and range. I was glad to have Fox in HD albeit a bit degraded on quality, given I could not receive WYFX at all at the time.
Now though, I believe, is WYFX's main transmitter is more up to par for reception distance so they have went back to just an SD feed on WKBN's transmitter.
I swear, some people should have pace-makers installed to free up the resources. Breathing and heart beat taxes their whole system, all of their brain cells wasted on life support.-two bit brains, and the second bit is wasted on parity! ~head_spaz
