MPEG-2


Title: Generic coding of moving pictures and associated audio information


MPEG-2 provides a better utilization of resources and introduces multi-channel features for audio coding. A larger data transfer rate is specified and due to that a substantially better image quality is possible, compared with MPEG-1. Additionally extended functions are specified for the scaling of resolution, frame rate and quantization.


The most popular application is the DVD-Video using MPEG-2 video streams. For audio coding both AC-3 (by Dolby) and MPEG-2 is allowed, at least by the specification.
