Title: Resource allocation for H.264 video encoder: Sequence-level controller
Authors: Alexander Bronstein
Abstract: Tradeoff between different resources (bitrate, computational time, etc.) and compression quality, often referred to as rate-distortion optimization (RDO), is a key problem in video coding. With a little exaggeration, it can be claimed that what distinguishes between a good and a bad codec is how optimally it finds such a tradeoff. This is the first part of our paper presenting an algorithm for resource allocation in a scalable H.264 video codec. Here, we discuss a sequence-level resource allocation and control scheme. The scheme allows for optimal frame rate and frame dropping decision, optimal reference frame selection, adaptation to a wide range of bitrates and computational load balancing between different frames.
