摘要： A method and an apparatus using a system level clocking scheme to remove jitter from multi-media packets distributed over an asynchronous network, in particular an asynchronous network. The present invention overcomes the problems associated with jitter introduced in an asynchronous network by using various time stamps to synchronize a client device clock to a headend clock and to control the data flow in the client device to match the rate that the data is received by a broadband receiver coupled to the headend. A first time stamp is prepended to the transport packets when the packets are received from the headend. A second time stamp is placed in the data frame when the data frame is placed on the network. A third time stamp is placed in the data frame when the data frame is received from the network. The second and third time stamps are used for synchronizing the client clock to the server clock, which is in turn frequency locked to the headend clock. The first time stamp is used for data flow control wherein the client controls the data flow to correspond to the rate the data is received at the server.

摘要： A method and apparatus for ensuring a correct satellite signal connection. Specifically, a user selects a satellite signal via an integrated receiver/decoder (IRD) from at least one satellite, and the IRD sends a command signal to a selector switch to acquire and lock onto said satellite signal. The IRD repeats transmission of the command signal to the selector switch once the IRD has acquired and locked onto said information signal. Thus, in the event that the selector switch failed to switch to a low noise block converter (LNB) corresponding to the initial command signal, then the repeated command signal helps to ensure that the selector switch switches to the LNB corresponding with the latest command signal sent by the IRD.

摘要： A method and system for providing personal video recording functions to a client viewing a broadcast program in a multi-client network. To provide the PVR functions, predetermined storage limits are allocated for each client in a storage device on the network. Each client is permitted to execute the PVR functions if the client's stored broadcast programming has not reached the client's predetermined storage limit. Otherwise, the client is only permitted to view the broadcast program in real time or the stored broadcast program. A client may clear space in the client's allocated portion of the storage device by fast-forwarding through stored broadcast programming.
