摘要： A method of delivering a variable bit rate (VBR) media stream in near real time includes identifying a selected media asset to be streamed to a media receiver, receiving an available access bandwidth at which the media receiver can receive data, and initiating a session setup for delivery of the selected media asset. The method further includes calculating a delay in decoding a media stream associated with the selected media asset at the media receiver based on the available access bandwidth, and a calculated required minimum transmission rate of a VBR media stream representative of the selected media asset. The method further includes transmitting the selected media asset at the required minimum transmission rate of the VBR media stream and providing the calculated delay to the media receiver such that the media receiver begins decoding the media stream in accordance with the calculated delay.

摘要： The present invention addresses the issue of jitter and clock drifting in streaming media applications. The present invention utilizes the Real Time Transaction Protocol (RTP) to embed MPEG packets within RTP packets in a Multiple Program Transport Stream (MPTS). Each MPEG packet in an MPTS stream is tagged at a gateway with: an arrival timestamp, a per-flow index and internal index to identify where the packet resides in an RTP packet and within a stream. After demultiplexing, this information is utilized in conjunction with the sending timestamp of each RTP packet to create a sending time for each MPEG packet to aid in the reduction of jitter and clock drifting.

摘要： Described herein are systems and methods for multiplexing and transmitting video data. The systems and methods use excess bandwidth in a channel available after meeting minimum transmission requirements for all bitstreams. A network device of the invention flexibly allocates this available bandwidth to minimize further rate reduction. More specifically, the network device periodically determines the available bandwidth, and divides the available bandwidth among multiple incoming bitstreams being multiplexed in order to increase downstream decoder buffer levels. By maintaining increased decoder buffer levels, future rate reduction of the video data may be avoided or applied to a lesser degree. Minimizing rate reduction in this manner improves bandwidth usage efficiency, and thus improves video data transmission and end-user output video quality.

摘要： Off-path admission control signaling in the presence of a network address translation (NAT) device may be provided. In response to a request for a content asset, a placeholder classifier may be created. The placeholder classifier may be used to allocate resources for providing the content asset to the client from a content server. The content server may communicate with the client, traversing the NAT device to identify a destination address and port for the client to which the content will be provided. The placeholder classifier may then be updated with the destination address and port.

摘要： Example embodiments herein provide for efficient distribution of content in a content distribution network (CDN) by a CDN server. The content is efficiently distributed by associating live content and time-shifted content with a common resource identifier, which may (in some instances) avoid re-transporting content across the network. To facilitate this, an entry point CDN server is configured to map the common resource identifier to a permanent storage location (that is itself associated with a different resource identifier) after expiration of the live viewing period.

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： 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.
