METHOD AND APPARATUS FOR MANAGING BIT RATE |
摘要 |
A crawl motion vector is determined based on a speed and direction of the crawling text to be displayed in a text crawl area. A determination whether to re-encode macroblocks in the plurality of pictures is made. The macroblocks in the plurality of pictures that are to be re-encoded are either macroblocks having motion vectors pointing to the text crawl area or macroblocks within the text crawl area. A lowest bit rate coding option for each macroblock to be re-encoded is determined, and each macroblock is re-encoded using the lowest bit rate coding option for the macroblock. |
