The following table shows the algorithm when run on the computational complexity of TMS320C6211B150M Statistics : The statistics in Table 1 the computational complexity in this system, test results can be dynamic compression of video frame rate , such as the frame rate dropped to second An even lower to get the ultimate image compression ADV612 compression ratio 7500:1 . The A / D after the rate 167Mb / s for NTSC digital video signal , for example, the first intra-frame coding using compressed to 250:1 , the dynamic test results according to the frame rate will be reduced to a second , and with the quality of the window The role of the image can be compressed to 25kb / s. 5 Conclusion proven , the adaptive rate control method is simple, real time, can meet the very low bit rate video surveillance images under the transmission industry .</span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="http://picsrv.fora.pl/xeon/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> </table>
