It's perfectly obvious you know absolutely nothing about how mpeg compression systems work. HD TV uses H264/AVC (aka AVC) and depending on platform ac3 or AAC for audio. Without mpeg compression Digital TV would be impossible.
Try reading and learning
https://en.wikipedia.org/wiki/H.264/MPEG-4_AVC
Typical HD broadcast format, the tuner in the box decodes the stream and because it's digital it simply copies it as is to the pvr HDD.
On playback the compressed data is decoded, after this the uncompressed audio and video is delivered delivered by HDMI to a display (normally a TV)
