Efficient Algorithms for MPEG Video Compression
Video compression is the enabling technology behind many cutting-edge business and Internet applications, including video-conferencing, video-on-demand, and digital cable TV. Coauthored by internationally recognized authorities on the subject, this book takes a close look at the essential tools of video compression, exploring some of the most promising algorithms for converting raw data to a compressed form.
Why Read This Book
You will get a practical, implementation‑oriented view of MPEG compression techniques and speedups so you can build or optimize encoders for real‑time use. The book emphasizes algorithmic tricks and performance considerations (fast DCT/IDCT, block‑matching, coding optimizations) that are directly applicable to embedded and software encoder work.
Who Will Benefit
Engineers and developers working on video codec implementation, real‑time encoding systems, or performance optimization who already know basic DSP and video codec concepts.
Level: Intermediate — Prerequisites: Basic DSP and signal processing (transforms and sampling), familiarity with block transforms (DCT), fundamentals of digital video (frames, macroblocks), and programming experience in C/C++ or similar.
Key Takeaways
- Implement efficient DCT/IDCT and transform‑based coding primitives suitable for MPEG pipelines.
- Optimize block‑matching motion estimation with fast search and complexity/performance tradeoffs.
- Apply practical rate control and quantization strategies to meet bitrate and quality targets.
- Implement entropy coding (variable length/Huffman and related techniques) used in MPEG standards.
- Evaluate and tune encoder performance for real‑time and embedded targets, including algorithmic and low‑level optimizations.

How It Compares
More implementation‑focused and efficiency‑oriented than Tekalp's Digital Video Processing (which is broader DSP theory for video) and narrower than Sayood's Introduction to Data Compression (which covers many compression types beyond MPEG).
