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： Described are modeling techniques. In accordance with one or more criteria, a determination may be made as to whether to use a dynamic model or a static model to model performance of components, such as storage devices, of a data storage system. A system may include first and second data storage systems where the first data storage system includes a computer readable medium with first code that performs processing in connection with data storage movement optimizations using one or more models including a dynamic model, and second code that generates and maintains the dynamic model used to model performance of storage devices. The second code may include code for performing first processing to determine device sets each of which does not share back-end resources of the second data storage system with any other device sets, and performing second processing to determine sets of performance curves corresponding to the device sets.

摘要： A write operation writes first data to a target logical address range included in a first logical address range of a virtually provisioned device. It is determined that physical storage is not allocated for the target logical address range. First processing is performed to allocate a first portion of physical storage having a first corresponding logical address subrange that includes the target logical address range. The first portion is allocated from a physical device included in a first storage tier. The first processing includes selecting the first storage tier from multiple storage tiers in accordance with selection criteria including metrics characterizing an expected workload or level of activity for the first corresponding logical address subrange of the virtually provisioned device. Mapping information is updated to indicate that the first corresponding logical address subrange of the virtually provisioned device maps to the first portion of physical storage.

摘要： A method is described that includes receiving a program request from a transceiver that includes a program request to receive a video program at the transceiver. The method also includes determining an amount of bandwidth on a channel available to the transceiver. The method further includes determining whether to provide a unicast stream or a multicast stream to deliver the requested video program to the transceiver in response to the program request based on a result obtained after implementing a policy control function that considers an amount of bandwidth on the channel to the transceiver. The method further includes formatting and selecting an incoming media stream in accordance with the result of the policy control function to provide a corresponding formatted unicast or multicast media stream that includes video data for the requested video program. The method further includes outputting the associated formatted unicast or multicast media stream on the channel.

摘要： In one embodiment, a method is described that includes receiving a conditioned bitstream that includes a digital insertion location and primary network packets that contain compressed video data. The digital insertion location includes replaceable network packets. The method also includes receiving a second bitstream that includes replacement compressed video data. The method also includes determining a location of the digital insertion location. The method further includes adjusting the bitrate of the replacement compressed video data to create adjusted replacement compressed video data.
