One Response to “Does HD cable have the same quality as Blu-Ray movies?”
No Marketplace or On Demand comes close to the quality of Blu-ray.
Blu-ray has 48 Mbps for Audio and Video bandwidth. It uses MPEG-2, MPEG-4 and VC-1 for video compression.
HD marketplace/On Demand/Satellite/Cable, etc. – they all have around 19 Mbps and use MPEG-2.
MPEG-2 needs bandwidth to work well. There is a night and day difference – Blu-ray is substantially better. The additional bandwidth and more efficient encoders (AVC/MPEG-4 and VC-1) allow for less pixelation and macroblocking and far better sound – Blu-ray uses new dts-Master Audio, Dolby TrueHD and multi-channel uncompressed PCM, whereas HD broadcast is stuck with lossy Dolby Digital.
