METHOD CIRCUIT AND SYSTEM FOR ADAPTIVE TRANSMISSION AND RECEPTION OF VIDEO
Disclosed is a method circuit and system for adaptive transmission and reception of video data. According to some embodiments, a source side transceiver may include a static frame detector adapted to detect static portions (i.e. some or all) of a frame to be transmitted. Static frame data may be removed or replaced by a marker indicating corresponding between the static data and data in a previous frame. In response to the transmission of a static frame, the source side transceiver may adjust a characteristic of a transmission circuit, option so as to reduce transmission circuit power consumption.
1 . A video source side transceiver comprising:
a frame status detector adapted to detect whether at least a portion of
a frame to be transmitter is substantially static relative to a previous frame.
2 . The transceiver according to claim 1 , further comprising a transceiver controller adapted to adjust a transmission circuit characteristic for transmission of a given frame upon said frame status detector indicating that at least a portion of the given frame is static.
3 . The transceiver according to claim 2 , wherein said controller is adapted to adjust a transmission circuit characteristic which results in a reduction of power consumption by said transmission circuit.
4 . The transceiver according to claim 3 , wherein said controller is adapted to adjust a transmission circuit characteristic upon said detector detecting that the static portion of the frame is greater than a threshold portion or percentage of the complete frame.
5 . The transceiver according to claim 1 , further comprising a transceiver controller adapted to replace remove or replace static portions of a frame.
6 . The transceiver according to claim 5 , wherein a static portion of a frame is replaced by a marker indicating to which portion of the previous frame the replaced portion corresponds.
7 . The transceiver according to claim 6 , wherein the marker indicates border pixel number or coordinates.
8 . The transceiver according to claim 1 , further comprising a transceiver controller adapted to signal a functionally associated sink side transceiver that a frame to be transmitted includes static portions.
9 . The transceiver according to claim 8 , wherein said transceiver controller is adapted to transmit to the functionally associated sink side transceiver an indicator indicating what portion or what percentage of the complete frame is static.
10 . A sink side transceiver comprising:
a transceiver controller adapted to switch between conventional frame reception mode and static frame reception mode.
11 . The transceiver according to claim 10 , wherein said controller is adjust a reception circuit characteristic for reception of a given frame upon determining that at least a portion of the given frame is static.
12 . The transceiver according to claim 11 , wherein said controller is adapted to adjust a reception circuit characteristic which results in a reduction of power consumption by said reception circuit.
13 . The transceiver according to claim 12 , wherein said controller is adapted to adjust a reception circuit characteristic upon determining that the static portion of the frame is greater than a threshold portion or percentage of the complete frame.
14 . The transceiver according to claim 10 , further comprising a frame buffer and a controller, wherein said controller is adapted to augment static portions of a received frame with data from the frame buffer.
15 . The transceiver according to claim 10 , further comprising a frame buffer and a controller, wherein said controller is adapted to augment portions of the frame buffer with corresponding dynamic portions of a received frame.
16 . A video transmission system comprising:
a source side transceiver including a static frame detector, wherein said source side transceiver is adapted to substantially suppress transmission of static portions of a current frame;
