摘要： A method, apparatus and computer program product for managing content sessions within a network is presented. The systems disclosed herein are able to detect a requirement to modify bandwidth usage within the network either proactively or reactively. In response, example embodiments apply an adaptive bit rate adjustment technique to the content sessions to adjust a data rate associated with each content session according to the requirement to modify bandwidth usage within the network. Example embodiments also then apply a quality of service adjustment technique to the content sessions to adjust a bandwidth allocation assigned between a client and server based upon the adaptive bandwidth adjustment technique. Application of the adaptive bit rate and quality of service adjustment techniques may be policy based. Example embodiments also may monitor a plurality of servers supporting content sessions, detect a failure at a first server and move content sessions to a second server.

摘要： A distributed resource management mechanism allocates transmission resources by distributing the resources among a plurality of service nodes each responsible for a portion of the resources according to a hash function. A data center receives resource allocation requests from applications, such as video services applications, including a computed hash value based on the desired resource and indicative of the service node for providing the requested resource. A remote resource management client identifies the resource and computes the hash based on a request from the application, and transmits the request to a resource management server on the service node having the resource indicated by the hash, thus avoiding centralized queuing or caching of the resource requests and instead delegating to the service nodes. Service nodes may redundantly share responsibility for the resources through a root node or a cluster arrangement, providing failover if a service node becomes inoperational.

摘要： A video server delivers video on demand (VOD) and other video services responsive to a remote selection application over an IP network from a personal communication device of a user, such as a cellphone or smartphone. The remote selection application drives a user interface of available content, and transmits a user selection request to the video delivery server via a public access network such as the Internet. The video server correlates the identity of the requesting user with a video services channel in communication with a settop box or similar device of the user, and delivers the content to the client video device for rendering. In contrast to conventional VOD, in which the video services request emanates from the settop box on the same communication path (QAM channel) as the downstream signals containing the VOD content, the remote selection application is independent of the client device on an HFC network.

摘要： A switched digital video (SDV) system is provided that includes an SDV manager for coordinating SDV sessions requested by subscriber terminals associated with a service group. An input is provided for receiving content to be broadcast during the SDV sessions. At least one edge device is provided for receiving transport streams that include SDV programming provided by the input and for transmitting each transport stream over an access network to at least one of the subscriber terminals on one of a plurality of SDV channels. The SDV manager is configured to (i) monitor bandwidth used by the edge device to provide the SDV programming to the service group and (ii) cause a bit rate of at least one SDV program supplied to the edge device to be adjusted based on the monitored bandwidth usage.

摘要： A configuration as discussed herein includes a content management system. The content management system can reside in a central location or be distributed amongst multiple different locations in a network environment. In general, the content management system keeps track of configuration information for the retrieval of content. For example, the content management system identifies a presence of one or more content delivery sources in the network environment. The content management system utilizes the contact information to communicate with content delivery sources for discovery of configuration information. The configuration information can indicate: i) a respective address of the content delivery source, ii) a type of content outputted by the respective address, iii) a format of the content such as streaming data outputted by the respective address. The configuration information can be used to identify an address in which to retrieve requested content according to a desired format.

摘要： A dynamic service group discovery and mapping approach avoids manual assignment of stream channels for transporting video services to the client devices that provide the video services to an end user. Client devices, such as set-top boxes, receive video services such as video on demand (VOD), switched digital video (SDV), pay-per view (PPV) and other narrowcast types of video for selective transmission. Each client device scans for visible stream channels, and sends a report indicative of visible stream channels to a dynamic mapping server. The dynamic mapping server applies aggregation rules for determining, based on the reported stream channels, which client devices are in the same service group. By receiving reports from each client device, the dynamic mapping server identifies groupings of service groups by combining sets of client devices receiving common channels, and “builds” the service groups as additional reports indicate common stream channels visible to multiple set top boxes.

摘要： An advertisement storage and filtering system for selectively identifying targeted advertisements to be stored in the memory of the STB. This storing of the selected advertisements can be accomplished in a number of ways. In one embodiment, the advertisements, in real-time and as they are received at the STB, are processed by the STB and only those advertisements with the appropriate characteristics are stored on the hard drive (HD). This may require some buffering of the advertisements in the STB memory as the STB processes and determines whether or not to store the advertisement. The information required to determine whether or not to store the advertisement could also be sent in advance, e.g., as a data service in an advertisement channel. Alternatively, the STB may store incoming advertisements in a memory temporarily and subsequently determine whether or not to retain the stored advertisements.

摘要： A switched digital video (SDV) system includes an SDV manager for coordinating SDV sessions requested by subscriber terminals associated with at least one service group. The SDV system also includes an input for receiving content to be delivered during the SDV sessions and at least one edge device for receiving transport streams that include an SDV program provided by the input and for transmitting each transport stream over an access network to at least one of the subscriber terminals on one of a plurality of SDV channels.
