    Abstract: A system receives multiple data samples and determines time stamp values associated with each of the multiple data samples. The system identifies an earliest time stamp value and uses that time stamp value as an initial system clock value. The system may also subtract a delay factor from the earliest time stamp value to account for delay in decoding the multiple data samples. The earliest time stamp value is also communicated to an audio decoder and a video decoder. The audio and video decoders provide clock data back to a component that maintains the system clock value. If the difference between the clock data received from the decoders and the system clock value exceeds a threshold value, the system clock value is recalculated.

    Abstract: Strategies are described for transmitting control information from a host module to a client module. The host module transmits the control information in-band along with a stream of media content information packets. The control information can be used to govern the operation of the client module. In one case, the control information alerts the client module to a discontinuity in streams, which may be the result of the user changing channels via the host or client module, etc., issuing a seek instruction, and so forth. Transmitting the control information in in-band fashion is advantageous because it reduces the need for complex linking between the control information and the associated content information.

    Abstract: Strategies are described for coalescing the processing tasks associated with a series of control events that occur relatively close together in time. The coalescing can involve eliminating redundant tasks by more directly advancing to a terminal control state. One exemplary application of the control coalescing is in the playback of media content information in a networked environment. When a user enters a series of commands to repeatedly change the channel, or repeatedly seek new positions within a single stream, the control coalescing comes into play by aggregating these control events so that it requires fewer control processing tasks to perform. This provision helps reduce the latency associated with handling multiple control events that occur close together in time.
