MPEG-4 is the latest compression standard developed by MPEG (Moving Picture Experts Group). MPEG-4 requires lower bit rate as compared to MPEG-2 for transmission. For example, the quality of a 10Mbps MPEG-4 video is comparable to an 18Mbps MPEG-2 video. Hence, the broadcaster is able to include approximately 2 programmes within the same bandwidth.
