摘要： A technique for supporting over-the-top video-on-demand separates metadata ingest and real content ingest such that navigation needs only the metadata ingest to have been completed. The real content ingest can occur later if the navigation results in the real content being selected and if the selected content has not been ingested already. Additionally, content identifiers with limited range are used over and over to identify a practically unlimited range of available over-the-top content by mapping virtual content identifiers to dynamic content. The content metadata and real content ingest are synchronized on a video-on-demand system using the dynamically allocated content identifiers. Playlists can be virtualized with a logical content identifier which maps to a list of virtual content identifiers. Existing video-on-demand infrastructures can simultaneously support both static and dynamic content with preexisting video-on-demand back offices and video-on-demand clients.
摘要翻译：用于支持顶级视频点播的技术分离元数据摄取和实际内容摄取，使得导航仅需要元数据摄取才能完成。如果导航导致选择真实内容并且所选择的内容已经没有被摄取，则真实的内容摄取可以发生。此外，通过将虚拟内容标识符映射到动态内容，一次又一次地使用具有有限范围的内容标识符来标识实际上无限范围的可用顶层内容。使用动态分配的内容标识符，在视频点播系统上同步内容元数据和实际内容摄取。可以使用映射到虚拟内容标识符列表的逻辑内容标识符虚拟化播放列表。现有的视频点播基础设施可以同时支持既有的视频点播后台和视频点播客户端的静态和动态内容。

摘要： A resource reservation and admission control scheme uses pseudowires to reserve bandwidth over a layer-2 and/or layer-3 network. The pseudowires are associated with ports on different network processing devices. During a resource reservation and admission control session, the physical links used by the pseudowire are selected and reserved to more effectively allocate network bandwidth. The negotiated pseudowire is then used to transport content for a communication session over the network. In one example application, the resource reservation and admission control scheme is used during a Downstream External PHY Interface (DEPI) session for pseudowires established between a Modular Cable Modem Termination System (M-CMTS) Core and an Edge Quadrature Amplitude Modulation Interface (EQAM) device. However, the reservation protocol can be used in any application that needs to reserve bandwidth over an Internet Protocol (IP) network.

摘要： A technique for managing the distribution of digital video content to multiple end-user devices is disclosed. The technique involves statistically multiplexing multiple VBR encoded video streams into an access channel, such as a data over cable service interface specifications (DOCSIS) bonded group, and utilizing quality of service capabilities of an edge device, such as a cable modem termination system (CMTS) or an edge quadrature amplitude modulation (QAM) device, to buffer and schedule IP packets, which carry the VBR encoded video streams, so that packets are not dropped during periods of congestion. Utilizing the quality of service capabilities of an edge device makes it possible to statistically multiplex VBR encoded video streams in a narrowcast application such as Video on Demand (VOD) or Switched Digital Video (SDV) while eliminating the need for process intensive transrating/transcoding operations.

摘要： Described herein are data transmission systems and methods that employ flexible memory usage techniques. The techniques allocate memory to include a plurality of block pools, where each block pool includes a set of blocks having a memory size common to the block pool. The number of block pools and common memory size for each may be determined according to the current transmission demands for the bit streams and channels being serviced. A processor for the network device then allocates data from multiple bit streams into a block in one of the block pools based on the memory requirements for the incoming data. The number of blocks may also be varied based on changing transmission demands.
