    摘要： Methods and apparatus are provided for multi-user communication of multimedia content including dividing a client's scene into a non-shared and shared parts. In a disclosed embodiment, the non-shared parts of a scene may be organized into one or more single-user nodes with which other clients cannot interact. The shared parts of the scene are organized into one or more multi-user group nodes. These multi-user group nodes enable multiple clients to access the same scene and to interact with its shared content. Each multi-user group node is an extension of a Group node. In addition to the functionality provided by a single-user group node, a multi-user group node wraps its children with control mechanisms required for supporting multi-user communication. These control mechanisms may be provided as boolean exposed fields that act as switches to control initiation of interaction, update control, privacy, and object accessibility. A client's scene may have multiple multi-user group nodes represented in hierarchical order or each representing a different part of a shared scene.

    摘要： Techniques to deliver targeted advertisements and multimedia contents to viewers. Various types of advertisements are encoded and transmitted. The advertisements may be targeted for different coverage areas (e.g., national and local levels) and may further include various categories (e.g., kids, sports, business, and so on). At the terminal, one or more advertisements may be selected for display based on various selection schemes. The particular advertisement to be selected for display at a terminal may be based on the terminal's assigned profile or user interaction at the terminal. The profile may be assigned based on the last program viewed at the terminal, a particular filter icon selected at the terminal, the observed television viewing habits of the viewer at the terminal, and so on. The techniques may also be advantageously used for delivery of other multimedia contents and for other applications.

    摘要： Efficient messaging techniques that facilitate interactive program guide (IPG) delivery and allow a terminal to specifically designate requested items of information from a server. The IPG can be provided via a number of IPG pages, with each page including a number of defined regions. In one method, selection for a particular region of a particular page is received at a terminal and a determination is made whether the selected region is currently received. If the answer is no, a request for the selected region is generated and sent to a server. The request can conform to a particular message format that includes a number of fields, e.g., a region ID field that identifies the selected region, a subtype field that identifies a particular type, a time slot field that identifies a specific time slot, and a page offset field that identifies a specific page from among many.

    摘要： Techniques to efficiently deliver interactive program guide (IPG) to a number of terminals. Each IPG page can be decomposed into a guide portion that is specific to each IPG page and a background portion that is common for all IPG pages. The background portion can be further decomposed into a time-varying video portion and other static portions. In one method for regenerating a selected IPG page, packets with a first PID for a first sequence of pictures having included therein one or more slices defined for at least a time-varying portion (e.g., the video portion) retrieved and decoded. Packets with a second PID for a second sequence of pictures having included therein one or more slices defined for at least a portion specific to the selected IPG page (e.g., the guide portion) are also retrieved and decoded. The second sequence can be coded with one I, P, or B picture for each GOP, and can be combined as and replaces an I, P, or B picture, respectively, in the first sequence or the last picture in the GOP. The second sequence can also be coded as a one-picture GOP that can replace a B-picture, or be inserted between pair of pictures, in the first sequence.

    摘要： The present invention provides multi-user interaction for multimedia communication. In one embodiment, a process for multi-user interaction for multimedia communication includes generating a message on a local user machine, the message including object-based media data (i.e., streamed, digital audio data or streamed, digital video data or both), and transmitting the message to a remote user machine, in which the local user machine displays a scene that includes the object-based media data, the scene being shared by the local user machine and the remote user machine. The remote user machine constructs the message using a message handler class. In one embodiment, the multi-user inter-action for multimedia communication is an extension to MPEG-4 Version-1.
