  • Publication number: 20120287344
    Abstract: 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.
