/**
* @description
* This file contains functions that allow one to decode MPEG-2 compliant video.
* The code is based on the MPEG-2 specification (ISO/IEC 13818-2). The MPEG-2 decoding
* is a work in progress, although it works within a limited test range. Throughout the
* source code, citations are made in cases where an understanding of the code would be
* helped by looking at an outside source. The format I have chosen is
* (cite NUM#, LOOKUP_INFO). NUM=1 refers to ISO/IEC: 13818-2, and NUM=2 refers to the reference
* MPEG implementation written in C, available at [www.mpeg.org].
