H.264 Inter Coding

Posted on April 24, 2011 by annapureddy

In this post, I will examine the inter-coding aspects of H.264. Inter-coding is designed to exploit temporal correlation in a given slice. For example, when encoding a background which remains the same through several frames, a macroblock which is part … Continue reading →

H.264 Intra Coding

Posted on April 18, 2011 by annapureddy

In this post, I will outline the algorithms used to encode macroblocks in intra-mode. Intra coding is designed to exploit spatial correlation in a given slice. For example, when encoding a slice which has uniform color throughout, there is a … Continue reading →

Overview of the H.264 codec pipeline

Posted on April 17, 2011 by annapureddy

In this post, I will present an overview of the H.264 encoding/decoding pipeline — the algorithms and processing used to convert a source RGB input into H.264 video, and to decode a H.264 bitstream into RGB output. Here are links … Continue reading →
