Abstract

A method for operating conflicting source devices communicating over the same self-configurable asymmetric link, comprising: transmitting uncompressed video from a first source device to a first sink device over a first direction of a self-configurable asymmetric link; receiving a request to transmit uncompressed video from a second source device to a second sink device over the opposite direction of the self-configurable asymmetric link; locating an accessible rendering device able to receive compressed video from the second source device and to transmit uncompressed video to the second sink device without flipping the direction of the self-configurable asymmetric link; and transmitting compressed video from the second source device to the rendering device, whereby the rendering device renders and transmits the video to the second sink device.

Claims (5)

1. A method for operating conflicting source devices communicating over the same self-configurable asymmetric link, comprising: transmitting uncompressed video from a first source device to a first sink device over a first direction of a self-configurable asymmetric link; receiving a request to transmit uncompressed video from a second source device to a second sink device over the opposite direction of the self-configurable asymmetric link; locating an accessible rendering device able to receive compressed video from the second source device and to transmit uncompressed video to the second sink device without flipping the direction of the self-configurable asymmetric link; and transmitting compressed video from the second source device to the rendering device, whereby the rendering device renders and transmits the video to the second sink device.

2. The method of claim 1 , wherein the low throughput channel supports bi-directional compressed video stream.

3. The method of claim 1 , further comprising flipping the direction and then transmitting the compressed stream.

4. A method for operating an asymmetric network comprising a self-configurable asymmetric link, the method comprising: receiving a request to transmit a first uncompressed video from a first source device to a first sink device over the self-configurable asymmetric link; setting the self-configurable asymmetric link to support the uncompressed transmission; receiving a request to transmit a second uncompressed video from a second source device to a second sink device over the self-configurable asymmetric link, wherein the first and the second uncompressed video streams are to be transmitted over the self-configurable asymmetric link in opposite directions; and transmitting a compressed stream from the second source device to a rendering server which is able to render and transmit the second uncompressed video to the second device while the first uncompressed video is being transmitted.

5. A method for operating multiple video sources and multiple video sinks communicating simultaneously over an asymmetric network, comprising: transmitting uncompressed video from a first source device to a first sink device over an asymmetric network; receiving a request to transmit uncompressed video from a second source device to a second sink device over the opposite direction of at least one of the asymmetric communication links comprised in the asymmetric network; locating an accessible rendering device able to receive compressed video from the second source device and to transmit uncompressed video to the second sink device approximately without affecting the uncompressed video that is being transmitted; and transmitting compressed video from the second source device to the rendering device, whereby the rendering device renders and transmits the video to the second sink device.
