Embodiment Construction

[0034] discussed below Figures 1 to 4 And the various embodiments used to describe the principles of this invention in this patent document are by way of illustration only and should not be construed as limitations of the invention in any way. Those skilled in the art will understand that the principles of the present invention may be implemented in any suitably arranged wireless network.

[0035] figure 1A general overview of a wireless network 100 with streaming video and / or audio capabilities is illustrated. For simplicity, while illustrating the principles of the present invention, the following description will mainly discuss the transmission of real-time video signals from a base station to a mobile station or from one mobile station to another mobile station. However, it should be clearly understood that the principles of the present invention are in no way limited to wireless transmission of video signals. In fact, the transmission priority system according to the ...

Abstract

A wireless communication device is disclosed that is capable of receiving an input RF data signal and generating therefrom a base layer data stream and at least one enhancement layer data stream. The wireless communication device comprises: 1) a base layer decoder; 2) at least one enhancement layer decoder; 3) a variable mode receiver for decoding in multiple physical modes such as BPSK, QPSK, QAM, etc. and multiple code rates tune the RF input RF data signal, and 4) a receiver mode controller for controlling the physical mode of the variable mode receiver. The receiver mode controller causes the first demodulated output signal of the variable mode receiver to be transmitted to the base layer decoder when the variable mode receiver is operating in the first physical mode, and when the variable mode receiver is operating in the first physical mode In the second mode, the second demodulated output signal of the variable mode receiver is transmitted to at least one enhancement layer decoder.

Description

technical field [0001] The present invention relates to video coding technology, and in particular to a coding system for sending streaming video in a wireless network. Background technique [0002] In recent years, real-time streaming of multimedia content over wireless networks has become quite common. A wider range of interactive and non-interactive multimedia applications such as news-on-demand, live Internet TV news program browsing, video conferencing and other situations rely on end-to-segment streaming video or audio technology. First, unlike non-real-time retrieval and browsing or later real-time playback, streaming video and audio applications require encoding and sending the video or audio signal over a data network to a receiver that must decode and play the video or audio signal in real time. [0003] In a wireless network, it is paramount that the video bitstream should be transmitted as much as possible. Layered source coding is one of the most effective way...
