Expand a TV service information.
Question14:
Are the video & audio bitrates fixed or variables?
All the bitrates are variable.
Question15:
Is there any channel that broadcasts in 4:3 aspect ratio?
No, all the channels are broadcasting in the aspect ratio of 16:9.
Question16:
Why is the Chroma in 4:2:0? Would a Chroma format of 4:2:2 be decodable by the receivers?
It’s 4:2:0 because that is the standard of DVB-T. A 4:2:2 transmission would not be decodable by the
televisions because they wouldn’t know how to interpret the signal. The 4:2:2 gives better accuracy, but
it’s only used for professional purposes.
Now, take a look at all the different tables that are being broadcasted:
Question17:
What can you find at the PAT?
At the PAT (Program Association Table) we can find what the PMT does, the .TS carry and its PIDs.
