Method and arrangement of adaptively multiplexing data of a plurality of video channel |
摘要 |
<p>A method of adaptively multiplexing a plurality of video channel data is disclosed. A multiplexed data includes a plurality of frames each of which contains a plurality of sub-frames. The video channel data are adaptively allocated to the sub-frames. A memory occupancy value of a buffer, which is provided in each of a plurality of video channels, is determined. The buffer is arranged to receive the corresponding video information. A plurality of control signals are produced each of which indicates the memory occupancy value of the corresponding buffer. Following this, a look-up table is accessed which includes a plurality of video channel assignment data for assigning the video channel data to The sub-frames. Thus, one of the channel data assignment data is derived from the look-up table. The video channel data are then multiplexed using one of said channel data assignment data derived from the look-up table.</p> |
