  • ADAPTIVE DISPLAY STREAMS
    Publication number: 20130219073
    Abstract: A transcoding device receives an input stream representing media information designated for display at a sink device. The transcoding device generates multiple display streams based on the input stream, wherein each of the display streams has a different transmission characteristic, such as a different bit rate or resolution. The transcoding device selects one of the generated display streams based on a network characteristic, such as a bandwidth or latency, and communicates the selected stream to the network for transmission to the sink device. In response to a change in the network characteristic, a different one of the generated display streams is selected and communicated to the network for transmission to the sink device.
