I am looking for some hardware & software that will enable me to better enjoy high-resolution TV.
My TV is a fullHD Sony 40X3500.
Blu-Ray DVDs are hard to find where I live, so I record HD broadcasts (1920x1088 at 25f/s) on my satellite receiver and play them back via a DVICO M-4130SH hard-drive media player.
The files I receive do not seem as good as the Blu-Ray disks themselves. Could somebody reading this suggest why this might be?
Blu-ray uses the "High capability Profile" with fidelity level 4.1, but after I reMux the TRP transport stream recorded files to M2TS files, the files have a "Main capability Profile" at level 4.
Would the satellite broadcasters be using Blu-ray DVDs to broadcast the files and removing the following techniques from the stream:
* Monochrome Video Format (4:0:0)
* 8x8 vs. 4x4 Transform Adaptivity
* Quantization Scaling Matrices
* Separate Cb and Cr QP control
which is the difference between the Main and High profiles, or is there another process going on that I can’t put my finger on?
The only other thing I know about my files is that they have CABAC compression with 2 reference frames.
The HD satellite broadcast has a maximum bitrate of 20 Mbit/s.
Any help or advice is gratefully appreciated.
