Embodiment Construction

[0021] One aspect of the present invention provides a method of processing high-definition video data to be transmitted over a wireless medium, the method comprising: i) receiving a packet of length L bytes, where L=(M×n×K )+A, where M is the depth of the interleaver, n is the number of interleavers, K is the code length of the code, and A is the number of remaining bytes relative to M×n×K bytes, wherein the remaining bytes are located at At the end of the information packet, wherein M×n×K bytes represent M×n codewords, wherein the remaining bytes sequentially form a plurality of remaining codewords, wherein the plurality of remaining codewords include the The final codeword at the end, ii) based on the code length (K), outer codes the M×n codeword and the plurality of remaining codewords, iii) shortens the final codeword such that the resulting shortened codeword is in length each remaining codeword shorter than the information packet; and iv) adding dummy bits to the outer c...

Abstract

A method and system for processing high definition video data to be transmitted over a wireless medium is disclosed. In one embodiment, the method includes receiving an information packet having the length of L bytes, wherein L=(MOEOE)+A, and where: M is the depth of an interleaver, n is the number of interleavers, K is an encoding code length and A is the number of remainder bytes with respect to MOEOE bytes, wherein the remainder bytes are located at the end of the information packet. MOEOE bytes represent MOE codewords, wherein the remainder bytes sequentially form a plurality of remaindercodewords, and wherein the plurality of remainder codewords comprise a last codeword which is located at the end of the remainder codewords. The method further includes i) shortening the last codeword such that the resultant shortened codeword is shorter in length than each of the remaining codewords of the information packet and ii) adding dummy bits to the outer encoded data so as to meet a predefined size requirement for an outer interleaver.

Description

technical field [0001] The present invention relates to the wireless transmission of video information, and more particularly, to the transmission of high-definition video information through wireless channels. Background technique [0002] With the increase of high-quality video, more and more electronic devices, such as consumer electronic devices, adopt high-definition (HD) video, which can require a bandwidth of about 1 Gbps (gigabits per second) to transmit. Therefore, when transmitting the HD video between devices, conventional transmission methods compress the HD video to a fraction of its size to reduce the required transmission bandwidth. The compressed video is then decompressed for serving. However, every time video data is compressed and subsequently decompressed, some data is lost and picture quality is reduced. [0003] The High-Definition Multimedia Interface (HDMI) specification allows uncompressed HD signals to be transmitted between devices via cables. ...
