摘要： A method for controlling an interactive video service is provided. The method includes the following steps: receiving a control request sent by a terminal device; obtaining an identifier of a Set Top Box (STB) device corresponding to the terminal device; and controlling a media stream of the STB device corresponding to the identifier of the STB device according to the control request. A system and a device for controlling an interactive video service are also provided. Thus, through the interaction between the terminal device and a Video On Demand (VOD) system, the program guide browsing and on-demand control for the interactive video service are realized for STB users. Therefore, without significantly modifying the broadcast and television network, the problem that some STB users cannot use an interactive video service currently is solved. In addition, the STB users can perform operations such as program guide browsing, on-demand initiating, and on-demand session control on handset devices, so that desirable service experience is achieved.

摘要： Techniques and tools are described for scalable video coding and decoding. For example, a 3D sub-band video encoder includes an embedded base layer codec as well as temporal sub-band transforms and spatial sub-band transforms. The placement of the base layer codec among the sub-band transforms and the role of the base layer codec in scalable video coding vary depending on implementation. In general, the base layer codec provides efficient compression at low bit rates and produces a base layer compressed video bit stream compatible with existing decoders. At the same time, the 3D sub-band video encoder provides spatial and temporal scalability options at higher bit rates, refining the base layer video. A corresponding 3D sub-band video decoder includes an embedded base layer decoder.
摘要翻译：描述了可扩展视频编码和解码的技术和工具。例如，3D子带视频编码器包括嵌入式基层编解码器以及时间子带变换和空间子带变换。基带编解码器在子带变换中的布置以及基础层编解码器在可伸缩视频编码中的作用根据实现而有所不同。通常，基层编解码器以低比特率提供有效的压缩，并产生与现有解码器兼容的基本层压缩视频比特流。同时，3D子带视频编码器以更高的比特率提供空间和时间的可扩展性选项，从而改善基本层视频。相应的3D子带视频解码器包括嵌入式基本层解码器。
