Many MPEG-2 encoding applications are real-time; this implies that the video signal must be
encoded with no significant lookahead. However, there exist non-real-time applications that …

Although a GOP (group of picture) length is often fixed in MPEG, this may not guarantee the
best picture quality from the point of view of coding efficiency. Furthermore, it is also well …

A rate controller for allocating a bit budget for video frames to be encoded is disclosed. The
rate controller of the present invention considers many different factors when determining …

This paper presents a practical two-pass VBR coding algorithm for digital storage
applications, which provides consistent visual quality perceptually and satisfies a fixed total …
