CHANNEL RATE PREDICTING METHOD WHICH USES SIGNAL STRENGTH INFORMATION FOR PREDICTING AN OPTIMUM VIDEO CHANNEL RATE ON A WIRELESS NETWORK THROUGH A VIDEO QUALITY DISTORTION ESTIMATING FUNCTION

摘要

PURPOSE: A channel rate predicting method which uses signal strength information is provided to reduce the loss of video quality by using an LDPC(Low Density Parity Check) code.;CONSTITUTION: A server predicts video channel rate by using estimated channel capacity. The server extracts a scalable video by using the predicted video channel rate. The sever performs channel coding of the extracted scalable video. The server transmits the channel-coded video to a terminal. The server minimizes video quality distortion by applying differential rate according to the property of a video frame through an LDPC code.;COPYRIGHT KIPO 2013
