Considerations in Evaluating and Choosing HDTV MPEG-2 Encoders
The paper covers considerations in choosing a high definition MPEG-2 encoder. — Areas explored include; Tiled versus striped architectures and the underlying problems; How motion vectors need to be cross coupled to conserve efficiency; What motion vector range REALLY means to performance; What is the difference between hierarchical, partial exhaustive and fully exhaustive search is, and why bigger numbers may mean poorer performance; How buffer management can significantly effect the subjective performance of an encoder; The importance of dynamic performance testing vs. steady state including caveats of using some current objective and subjective test techniques: Statistical video and data multiplexing with mixed HDTV and SD.
