Comparison of Video Coding Techniques for Lossy Transmission

This technical report presents a comparative analysis of three video coding techniques: Temporal Layered Coding (TLC), Single-State Coding (SSC), and Multi-State Video Coding (MSVC) in the context of lossy video communications. The study investigates the performance of these coding schemes under varying loss rates and coding options, maintaining a constant total bit rate. MSVC is highlighted as a Multiple Description Coding scheme that allows for independent decoding of multiple streams, enhancing state recovery through motion compensated frame interpolation. The report details the experimental setup, including the use of the H.264 codec, and analyzes the results across different motion sequences. Findings indicate that MSVC outperforms both SSC and TLC, particularly in high motion scenarios and under significant packet loss. The report also discusses the implications of using intra updates and the effects of balanced versus unbalanced rate allocations on performance, concluding with a summary of the advantages and limitations of each coding technique in various transmission conditions.
