They both use asymmetric compression algorithms, based onmotion estimation. Their encoders are much more complex than decoders.The XYZ technique uses a symmetric algorithm, based on theThree-Dimensional Discrete Cosine Transform (3D-DCT). 3D-DCT wasoriginally suggested for compression about twenty years ago; however,at that time the computational complexity of the algorithm was toohigh, it required large buffer memory, and was not as effective asmotion estimation. We have resurrected the 3D-DCT-based videocompression algorithm by developing several enhancements to theoriginal algorithm. These enhancements make the algorithm feasible forreal-time video compression in applications such as video-on-demand,interactive multimedia, and videoconferencing. The demonstratedresults, presented in this book, suggest that the XYZ videocompression technique is not only a fast algorithm, but also providessuperior compression ratios and high qua | | 出版日期 | Book 1997 | | 关键词 | Standard; Standards; VLSI; Video-on-Demand; algorithms; architecture; communication; complexity; entropy; mul | | 版次 | 1 | | doi | https://doi.org/10.1007/b102475 | | isbn_softcover | 978-1-4757-8308-7 | | isbn_ebook | 978-0-585-32313-8Series ISSN 0893-3405 | | issn_series | 0893-3405 | | copyright | Springer Science+Business Media New York 1997 |
