Abstract: Methods and apparatus for allowing parties, e.g., individuals, at different locations to participate in an on-demand content delivery session are described. Dynamically updateable playlists are used to control content delivery to the session participants in a synchronized manner. Content may be delivered to different session participants from different servers with a different playlist corresponding to each session participant being used to control content delivery to the session participant's host platform, e.g., set top box. Either party may update the playlist with, optionally, each of the content delivery servers being controlled by a different or local copy of the jointly updateable play list. Thus, an inviting party and one or more joining parties are able to participate together in an on-demand session. While the participants may be served by the same or different content delivery servers, the parties are able to share images, audio, and/or video in a synchronized manner.

Abstract: A method of providing programming content from a video server to a client coupled to the video server by a video content network includes the steps of sending, to the client, a playlist describing an interrelationship between at least one program segment and at least one related segment; sending, from the video server to the client over the video content network, video content comprising the at least one program segment and the at least one related segment; and modifying the playlist via communication to the client. The steps of sending the playlist, sending the content, and modifying the playlist are all accomplished within a single video-on-demand session per user.

Abstract: Methods and apparatus for delivering data over extant infrastructure within a content-based network. In one embodiment, the network comprises a cable network, and the infrastructure comprises that nominally used for on-demand (OD) services such as VOD. The method includes the allocation of dedicated end-to-end network resources via a “session request, as well as data flow control and packet size adaptation, by a data server based on feedback from the requesting/receiving client device (e.g., DSTB) within the network. Mechanisms for retransmission requests for error recovery are also provided.

Abstract: A method and system is provided for processing a program stream for interactive viewing, wherein the program stream includes programming content relating to a program having a plurality of program segments. The program stream is received and divided into at least one block comprising an expanse of the program stream. In accordance with an embodiment of the invention, a block is measured based upon the normal play time of the programming content, or some other predefined measurement. A determination is then made as to whether the block comprises at least one complete program segment. In accordance with an embodiment of the invention, a program segment is a logical portion of TV show or movie, such as a specific story of a news show, a scene in a movie, etc. Upon identifying one or more programming segments, these segment(s) may be made available for interactive viewing prior to receiving the end of the program.
