    摘要: Embodiments of the invention are generally directed to adjustment of clock signals regenerated from a data stream. An embodiment of a method includes receiving a data stream from a transmitting device via a communication link, the data stream including stream data, a link clock signal, and timestamps to indicate a relationship between the link clock signal and a stream clock signal. The method further includes adjusting the stream clock based at least in part on one or more measurements related to the data stream, the one or more measurements including a count of a number of pulses of the stream clock during a period of time, or a measurement of a number of data elements from the data stream stored in a buffer at a certain point in time.

    摘要: Embodiments of the invention describe a multimedia stream switch capable of multiplexing the audio and the video data of a multimedia stream separately. The multiplexing features of embodiments of the invention enable a multimedia stream switch to control each multimedia data type separately instead of multiplexing the whole streams (i.e., multiplexing sets of audio/video data together). Furthermore, prior art multimedia stream switches need to regenerate audio clocks by using phase locked loop (PLL) circuitry which incurs manufacturing and development costs. Embodiments of the invention provide the mixing of audio and video data from different sources without the need for PLL circuitry.
