Tokens and policy descriptors are used for dynamic on demand session management in a distributed and scalable architecture for on demand sessions and resource management. The architecture includes an on demand client, a purchase server, and a session manager. A purchase token is generated at the purchase server and assigned to the on demand client. The purchase token represents at least one requested asset. In response to an on demand session set-up request corresponding to the purchase token from the on demand client to the session manager, the purchase token is expanded to generate at least one dynamic policy management descriptor for the on demand session. This provides token-based purchase authorization and policy management for on demand services.

A process distributing video streams to a plurality of addressees, comprising a marking step comprising adding at least one visual element to a video stream, which marking step is applied to an original video stream common to all the addressees and which is personalized for each addressee by addition of a visual element specific to the addressee that allows rapid visual identification of the addressee, wherein the added visual element replaces part of the original video stream that is stored in complementary information on a multimedia server.

A quota management system for Personal Video Recorders (PVRs) in which the storage space available on connected storage devices is shared between multiple content providers or multiple software programs.

Example embodiments of compiling and maintaining information for use in transmitting content to a machine via a network are presented. In an example embodiment, a request for information regarding a user of a client device is received at the client device via a communication network from a server storing a user profile. An input including a user response to the request for information is received at the client device. The user response to the request for information is transmitted from the client device via the communication network to the server for updating the user profile. Selected content pushed by the server based on the updated user profile is received at the client device via the communication network from the server.

In one embodiment, a method of transmitting streaming media and advertisements to viewers at a plurality of viewer nodes is disclosed in which a plurality of viewer groups are created. Each viewer node is assigned to one of the plurality of viewer groups, wherein the assigning includes creating an advertising group map disclosing an advertising group to which each viewer belongs and transmitting the advertising group map to each viewer node. At the head end, at least one media stream is received including media content. A plurality of presentation streams is formed, each presentation channel corresponding to one of the viewer groups, by replicating the at least one media stream, each presentation channel including the media content and advertisements, wherein the advertisements replace previously scheduled advertisements. Each of the presentation channels is transmitted to at least one viewer node in said viewer group corresponding to said presentation channel.

An ad in a movie can be a static ad having a position in the movie that cannot be moved, or a dynamic ad having a position in the movie that can be changed. When a viewer wishes to skip a portion of the movie containing the ad, the playback system determines whether the ad is static or dynamic. If the ad is static, only the portion of the movie preceding the static ad can be skipped; the ad is unskippable. This technique is referred to as bounceback since the end of the skip bounces back to the start of the static ad. If the ad is dynamic, it is moved to after the end of the skip. This technique is referred to as slip-ad since the ad slips to later in the movie. When a movie has multiple ads, some can be static and some can be dynamic.

Methods, systems, and computer program products that automatically categorize and/or assign ratings to content (video and audio content) uploaded by individuals who want to broadcast the content to others via a communications network, such as an IPTV network, are provided. When an individual uploads content to a network, a network service automatically extracts an audio stream from the uploaded content. Words in the extracted audio stream are identified. For each identified word, a preexisting library of selected words is queried to determine if a match exists between words in the library and words in the extracted audio stream. The selected words in the library are associated with a particular content category or content rating. If a match exists between an identified word and a word in the library, the uploaded content is assigned a content category and/or rating associated with the matched word.

Mass amounts of information, such as entire libraries of songs or movies, for example, may be stored locally near end-users, and this information may be accessed and reproduced in response to commands received from a transmitting station via a network. When a radio or television station desires to transmit a song or movie, for example, the radio or television station can, rather than transmitting the entire song or movie, merely transmit a command for reproducing the song or movie. An end-user's performance reproduction device, such as an enhanced radio or a television set, then accesses and reproduces the locally stored song or movie. Since the radio or television station need not transmit the entire performance, network traffic can be significantly reduced. The performance reproduction device may actively request information from the radio or television station when fresh or additional information is needed.

In one aspect, a method for managing streaming of video content to a client device includes providing the video content to a content distribution network for storage in a plurality of geographically separated resources of the content distribution network, dynamically selecting an advertisement media clip based on statistical information associated with a user of the client device, and receiving, from the client device via a packet-based telecommunication network, signaling to have the stored video content streamed to the client device. In response to the received signaling, the method includes transmitting to the client device via the packet-based telecommunication network and in one or more files having a format compatible with a media player on the client device, (i) an identification of a first resource of the content distribution network available to facilitate streaming of the stored video content to the client device, the identification being dependent at least in part on a relationship between a geographic location of the client device and geographic locations of the resources of the content distribution network and (ii) an identification of an advertising server, the identification of the advertising server being dependent at least in part on a relationship between the geographic location of the client device and a geographic location of the advertising server, wherein the one or more files, when processed by the client device, cause the client device to communicate with the first resource of the content distribution network and the advertising server to cause the stored video to be streamed to the client device by first resource of the content distribution network and cause the selected advertisement media clip to be streamed from the advertising server to the client device.
