- Description
- Video file encoded with the MPEG-2 codec, which is mainly used for over-the-air, satellite, and cable digital TV signals and DVD video; uses lossy compression for audio and video to significantly reduce the size of the video data; not as efficient as the H.264 format.
- Compressed audio file similar to an .MP3 file, but offers several performance improvements; examples include a higher coding efficiency for both stationary and transient signals, a simpler filterbank, and better handling of frequencies above 16 kHz; maintains quality nearly indistinguishable from the original audio source.
