Experimental results obtained using AVC/H.264 encoding in a CDMA/HDR multi-user environment with crosslayer optimized scheduling show performance comparisons of CBR and CPSNR encoding. 1 ...
Instead of transmitting all of the video content at low quality, the most important content can be transmitted at high quality while still preserving an acceptable quality for the remaining segments. ...
Similarly, the bitrate-PSNR mapping for soccer videos is found as shown in Figure 2 for soccer videos by averaging over a set of video shot instances. ...
