摘要： A method and system identify programming code that is appropriate to the architecture and capabilities of a set-top terminal in a cable television system. The appropriate programming code is identified from among a variety of code objects being broadcast from the headend facility of the cable television system. A platform identifier stored in the set-top terminal is matched to a corresponding platform identifier in an entitlement management message or other download locator message that specifies where in the transport stream from the headend a particular code object can be acquired. By acquiring the object corresponding to the message bearing a matching platform identifier, the set-top terminal acquires programming code compatible with its attributes. Additionally, the cable television system can then optimally support a varied population of set-top terminals.

摘要： This method and system allow a subscriber to a cable television service to receiving a listing or menu of programming available for that subscriber's set-top terminal to upgrade or enhance the features available over the cable system. A Directory of Services (DoS) message is transmitted over the cable system to the subscriber's set-top terminal. The terminal can then display for the subscriber the menu of programming available. This display may include a price for downloading each programming object. The subscriber can then, using a remote control unit or a user input device on the terminal, direct the set-top terminal to acquire a listed programming object. The DoS message will provide information enabling the set-top terminal to download the indicated programming object from the cable system in response to the subscriber's input. The subscriber can then have immediate access to upgraded or enhanced programming, the purchase of which is billed to the subscriber's account.

摘要： A Download Control Message instructs a set-top terminal in a cable television system to located and immediately begin downloading a code or other data object available over the cable system. The Download Control Message specifies, for example, the size, name, version and location (URL or transport stream and PID) of the object to be acquired by the set-top terminal. The terminal accordingly can begin immediate acquisition of the object. An address or other characteristic associated with the Download Control Message allows the system operator to target the Message to a particular set-top terminal or group of terminals.

摘要： A method and system manages and controls the download of programming, i.e., code objects, to a set-top terminal connected to a cable television system so as to prevent disruptions to service that may arise if only some of the objects specified are successfully downloaded and might, therefore, function improperly or conflict with existing applications. When the message to download new or additional code objects lists two or more objects to be acquired, the set-top terminal will only enable and execute downloaded objects if all the listed objects are successfully acquired. If only some of the objects the terminal has been instructed to download are acquired, those downloaded objects may either be purged or stored in memory without being enabled and executed. The system operator may specify in the message instructing the terminal to acquire new objects, whether the listed objects must be implemented as a group or not at all. The system operator may similarly specify if objects from an incomplete download are to be purged from memory.

摘要： A method of modifying a digital data stream composed of a sequence of frames, where each frame represents an image and includes a data field specifying a presentation time stamp value for the frame. If there is a discontinuity in presentation time stamp value between a next frame and a first frame, a value representing a stream time stamp of interest is assigned to a variable for representing the value of the stream time stamp of interest at a point of discontinuity in presentation time stamp, and a value of the presentation time stamp is assigned to a variable for representing the first frame's clock time based on presentation time stamp, and the next frame is stored in a database using as an index the value representing a stream time stamp of interest.

摘要： A method and apparatus for streaming multimedia data over a network is provided. A playlist file for a selected multimedia presentation is downloaded by a client device over the network from a streaming server using a transfer protocol. The playlist file provides a list of URIs for media files each providing compressed video data corresponding to a segment of the multimedia presentation. The compressed video data includes reference frames used for video compression. A data file that is associated with the playlist file is also downloaded by the client device over the network from the streaming server using a transfer protocol and provides information identifying a location, a size, and a time stamp for each the reference frames contained in the media files listed by the playlist file. This information can be used by the client device to perform trick plays and to switch and stitch between variant streams.

摘要： Simultaneous display of multiple audio/video (AV) programs transmitted over a digital link is described. At a source device, at least one non-composited digital transport stream is generated from the plurality of AV programs. The at least one non-composited digital transport stream is augmented with control information. The control information is operative to invoke simultaneous display of the plurality of AV programs on a display device. The at least one non-composited digital transport stream is then transmitted as augmented over the digital link. At a sink device, at least one non-composited digital transport stream having the plurality of AV programs is received over the digital link. Control information is extracted from the at least one non-composited digital transport stream. The plurality of AV programs are identified within said non-composited digital transport stream in response to the control information. The identified AV programs are then simultaneously displayed on the display device.

摘要： A set top box includes a tuner for receiving a switched digital video (SDV) stream from an SDV source, in which the SDV stream contains content and a default advertisement. The set top box also includes a memory for storing the SDV stream and a controller for generating and outputting an ad catalog to at least one of an ad server and an SDV manager, in which the ad catalog contains information useable by the ad server in identifying one or more alternative advertisements to be played by the set top box during play of the SDV stream in place of the default advertisement, and in which the controller is configured to receive the one or more alternative advertisements and to replace the default advertisement in the SDV stream.

摘要： A method and computing device that provides viewer impression data for a recorded digital video stream. The method receives a digital video stream as a series of segments, and stores it as a recorded digital video stream having a transition between two consecutive segments at a transition position. The method stores a notification tag that is associated with the transition, and that includes a tag position in the recorded digital video stream, a notification mode, and tag data. During playback of the recorded digital video stream, the method generates a play mode status event, and generates a transition notification when the playback encounters the notification tag and, based on the notification mode, the transition associated with the notification tag. The method collects viewer impression data for one of the two consecutive segments from the play mode status event and the transition notification.
