Abstract: A transmitter is configured to: receive a frame of video data from a data source; group bits corresponding to the frame of video data into a plurality of groups each corresponding to a plurality of levels of importance; reorganize the groups in order of importance to generate a reorganized frame of data with a group corresponding to a plurality of packet headers having a highest level of importance and arranged to be first among the groups; insert a value indicating a length of data bits corresponding to each packet header before each packet header; and transmit the bits corresponding to the frame of video data to the receiver for display on the display panel such that each group from among the plurality of groups is transmitted according to different protection techniques based on their corresponding levels of importance.

Abstract: A system of transmitting display data is presented. The system includes a frame encoding part configured to receive a source frame and output a compressed frame. The frame encoding part has: a difference unit configured to generate a difference frame using the source frame and an encode reference frame; an encode output unit configured to output a compressed version of either the source frame or the difference frame as a compressed frame; and a first compressed frame buffer configured to store a compressed version of the source frame as a new encode reference frame, wherein the frame encoding part further includes a frame decision unit configured to compare the image quality of frames respectively derived from the source frame and the difference frame.

Abstract: In a method for transmitting video for a display panel between a transmitter in electronic communication with a receiver over a wireless communication channel, the method includes: receiving, by a transmitter, a data signal from a data source; receiving, by the transmitter, a return signal from a receiver; encoding, by the transmitter based on the return signal, the data signal utilizing a plurality of encoder blocks to generate a layered encoded data stream, wherein a first encoder block encodes the data signal and each subsequent encoder block encodes a difference between an input of a preceding encoder block and an output of a quantizer of a preceding encoder block; and transmitting, by the transmitter, the layered encoded data stream to the receiver for decoding and display on the display panel.
