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的传输协议安全地传输和适配MC-EZBC视频。

通用多媒体访问（UMA）要求一种解决方案，其中内容要创建一次，然后可以适应给定的要求。关于UMA和可伸缩性（由于各种各样的最终客户端而经常需要使用），最适合的编解码器基于小波（如MC-EZBC），因为它们固有的大量缩放选项。但是，大多数用于将视频交付给最终客户的传输技术都针对H.264 / AVC标准，或者，如果需要可伸缩性，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。这样一方面可以使用高度可扩展的基于小波的编解码器，另一方面可以利用现有的网络技术而又不会增加高昂的实现成本。此外，我们将评估不同的缩放比例选项，以便为给定要求选择最佳选项。此外，对于需要数字版权管理的用例，我们将基于传输和比特流加密来评估不同的加密选项。
