Universal Multimedia Access (UMA) calls for solutions where content is created once and subsequently adapted to given requirements. With regard to UMA and scalability, which is required often due to a wide variety of end clients, the best suited codecs are wavelet based (like the MC-EZBC) due to their inherent high number of scaling options. However, most transport technologies for delivering videos to end clients are targeted toward the H.264/AVC standard or, if scalability is required, the H.264/SVC. In this paper we will introduce a mapping of the MC-EZBC bitstream to existing H.264/SVC based streaming and scaling protocols. This enables the use of highly scalable wavelet based codecs on the one hand and the utilization of already existing network technologies without accruing high implementation costs on the other hand. Furthermore, we will evaluate different scaling options in order to choose the best option for given requirements. Additionally, we will evaluate different encryption options based on transport and bitstream encryption for use cases where digital rights management is required.

利用基于 H.264 的传输协议对 MC-EZBC 视频进行安全传输和适配。


通用多媒体访问 (UMA) 需要一种解决方案，其中内容创建一次，然后根据给定的要求进行调整。至于 UMA 和可扩展性（由于终端客户端的种类繁多而经常需要），最适合的编解码器是基于小波的（如 MC-EZBC），因为它们固有的大量扩展选项。然而，大多数用于向最终客户端提供视频的传输技术都针对 H.264/AVC 标准，或者，如果需要可扩展性，则针对 H.264/SVC。在本文中，我们将介绍 MC-EZBC 比特流到现有基于 H.264/SVC 的流和缩放协议的映射。一方面，这使得能够使用高度可扩展的基于小波的编解码器，另一方面能够利用现有的网络技术，而不会产生高昂的实施成本。此外，我们将评估不同的扩展选项，以便针对给定要求选择最佳选项。此外，我们将针对需要数字版权管理的用例评估基于传输和比特流加密的不同加密选项。
