When televisions went digital, they used a format called MPEG-2. It allowed the movies and television shows to be broadcast through cable and linear systems. Sometimes, they were used by the satellite. There are eleven parts to it with the latest being created in 2004. MPEG4 is another type of format for handling audio and digital information.
It is compressed so that it can be broadcasted to the different channels that people use on their television. However, the difference between these two, MPEG-2 and MPEG-4, is that the MPEG-4 is a more updated version because it was created later with its latest part, part 33, being under development now. Its part 30 was established in 2014, which is ten years later than the last part of MPEG-2.
