Expert Solution
Step 1

Digital broadcast video and DVDs are compressed using the MPEG2 codec. MPEG-2 codec-encoded media files often have file extensions. mpg, .mpeg, .m2v, .mp2, or occasionally .mp3. It is still utilized in the DVD-Video standard and over-the-air digital television transmission under the name H.262.

Thus, option 1 is incorrect.

In 256-QAM, a kind of quadrature amplitude modulation (QAM), a carrier wave with a fixed frequency may exist in any one of 256 discrete and measurably distinct states on the constellation plot.

Thus, option 2 is wrong.

ATSC is not a valid option. Thus, option 4 is wrong.
