Abstract: A hybrid bitmap-mode video coding system encodes and decodes a plurality of video frames with optimized coding performance. The coding system filters a video frame to determine an appropriate encoding mode. In response to the video frame to be encoded in bitmap-mode, the coding system generates a bitmap and DCT-type data of the video frame. The bitmap data of the video frame are encoded losslessly to keep the high quality of the video frame. The DCT-type data of the video frame are encoded with compression. The bitmap-mode encoding enables the coding system to flexibly encode part of a video frame data lossless and encode the rest of the frame data lossy. As such, the lossless encoding of the frame provides high quality of important data of the frame, and at the same time maintains high compression ratio on less important data of the frame.

Abstract: Described herein is a technique for aggregating background traffic packets by the background users instead of performing a random access procedure to request an uplink resource for each new packet. Since the same physical random access channel (PRACH) resources are used for random access procedures by multiple UEs, collisions can occur. The PRACH is expected to operate with very low collision rates, but if the number of users increases, the collision rate increases as well as the error rate. The disclosed technique reduces the collision rate by reducing the number of random access procedures used to transmit background traffic.
