摘要:
A computer software application for end-to-end management of the delivery of IP-configured integrated multimedia signals (e.g., TV, video, Website, etc.), on an interactive basis, to a subscriber device (being a personal computer (PC) and monitor coupled thereto or television/set-top box combination). The system manager comprises an interactive program guide (IPG) component configured for providing to the subscriber an interactive program guide (IPG) permitting selection of the multimedia signals by the subscriber and a subscriber device component associated with the subscriber device and configured for receiving instructions from the subscriber. The subscriber device includes a decoder configured for converting the selected IP multicast format signals into a format for display on PC monitor or television. A PC component is configured for displaying the converted multimedia signals on the PC monitor in the form of a player window and for displaying a remote controller GUI on the monitor, the remote controller GUI being a model of a hand-held remote controller and controllable by the subscriber for controlling the selection of signals from the IPG. The interactive program guide provides drop down box selection and scroll bar GUI features.

In a system that provides decoding of A/V streams, this invention reduces switching delays between different streams by modifying the Program Identification (PID) values of the Audio and Video data to common PID values that are already known by the decoder. This technique allows the decoder to stay in a run state when switching between A/V streams, thereby reducing channel change times.

The PIP system enables display of a mosaic of favorite channels in a Picture-in-Picture (PIP) format to a subscriber terminal. Picture-in-Picture support is efficiently provided by sending only I-Frames of the secondary video channel to the end-user. That is, any unnecessary packets (null, B-P frames, audio, etc.) in the secondary video channel are stripped away. This method uses very little bandwidth and is STB agnostic.

A server at the edge of a broadband network distributes multimedia content streams to clients, while ensuring that the first data delivered to each client is key data (milestones) needed for correctly decoding the stream content. This is obtained by buffering the packets in the incoming stream and transmitting the packets from the buffer in an outgoing stream, starting with the most recent milestone placed in the buffer before a request to join the respective incoming stream is received. As the writing to and reading from the buffer are performed at different rates, the incoming and outgoing streams are eventually synchronized, at which point the client may be switched to receive the incoming stream directly.

A circular buffer in a video delivery server tracks a second copy of a live video stream to provide instant replay capability. When an end-user initiates the instant replay function, the circular buffer is copied to an instant-replay buffer, from which a replay of the video is sent to the end-user. During replay the end-user can use playback functions such as pause, slow-play, freeze frame, etc. Upon leaving the replay function the end user rejoins the live stream. The circular buffer also enables transmission of delayed copies of the live stream, time-shifted by predetermined intervals, which copies are multicasted to end-users. Upon request, an end-user may join a delayed version of interest. This allows the user to replay interesting content by jumping to a time-delayed version without missing the show and to catch up with real-time during e.g. commercial breaks.

A method for accessing triple play services provided through a server over a network to a portable device, the method comprising: receiving a signal from a user defining respective preference levels for the triple play services; determining a location for the portable device; determining which of the triple play services are available at the location; composing a list of available services at the location, the available services in the list being ordered in accordance with the respective preference levels; and, displaying the list on a display screen of the portable device, whereby the user may access the available services by selecting from the list.
