Re: Video used to be free said by me1212:As for quality of video, from what I have seen it goes like this for HD any way. Blu-ray>>>>>>OTA>>>>>>>Sat>>>>>cable. OTA may be in a position to loose it's spot if it hasn't already. Many stations have started broadcasting sub-channels. Each channel can only carry 19.39 mbps of video. Take a 1080i HD channel and break off 2 SD subchannels and you've now made an okay looking HD channel, look noticeable worse.

Pleasant Hill, MO | None of the HD digi stations here have more than one sub channel, we have 7 HD and only 3 have subs and like I said those 3 only have one sub. The rest only use their badnwidth for HD. |

Cable usually shoehorns 3 HD channels(sometimes only 2 if ESPN is involved) in to 6 Mhz(38.8 mbps) of bandwidth. Divide the 38.8 mbps by 3 and cable is delivering HD channels in about 13 mbps of bandwidth. OTA can still better that while also delivering 2 480i subchannels in addition to the HD channel.
