    摘要: 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.

    摘要: 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.

    摘要: An intelligent retransmission of data stream segments is disclosed. One embodiment comprises detecting a missing media data segment at a media receiver, assigning a value to the missing media data segment based upon media playback consequences of not utilizing the missing media data segment, comparing the value with a threshold, and requesting retransmission of the missing media data segment from a media server if the value meets a predetermined condition relative to the threshold. In this manner, retransmission is requested when it is determined that retransmission will improve playback performance relative to non-retransmission.

    摘要: A home entertainment network transmits audio/video decrypted from a DVD over a network to a media receiver using a secure channel. The A/V data is re-encrypted in a second encryption format amenable to transmission over the network. The media stream is thereby compliant with copy protection and digital rights management requirements. The media server constructs an emulated user interface corresponding to an actual instantiation of a navigation menu on the media server to solicit user input at the media receiver. The media server alternatively constructs a unique identifier of the DVD based upon the file structure on the DVD to search for menu navigation commands over an external network for heuristic navigation control.

    摘要: Media fragmentation may be provided. First, a request for a manifest may be received from a client. Then, in response to the received request for the manifest, the manifest may be sent to the client. Next, a request may be received from the client for a file fragment. The request may indicate a start time and an end time corresponding to the file fragment. The request may be in a format defined by the manifest. Then a lookup table may be queried for a first byte location in a media file corresponding to the start time and a second byte location in the media file corresponding to the end time. Next, a portion of the media file between the first byte location and the second byte location may be extracted from the media file. The portion may comprise the file fragment. The file fragment may be sent to the client.

    摘要: 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.
