Broadcasting System of a Satellite TV Channel

Broadcast systems of any satellite TV are encoding or formatting standards for the transmission and reception of terrestrial television signals. There are three main analog television systems in current use around the world: NTSC, PAL, and SECAM. The situation with worldwide digital television is much simpler by comparison. Most current digital television systems are based on the MPEG transport stream standard, and use the H.262/MPEG-2 Part 2 video codec. They differ significantly in the details of how the transport stream is converted into a broadcast signal, in the video format prior to encoding (or alternatively, after decoding), and in the audio format. This has not prevented the creation of an international standard that includes both major systems, even though they are incompatible in almost every respect. And we want to give a Primary knowledge about the total broadcasting system. But it is not easy to describe it, in this short note. So go inside the book and know about the concept.
