Method and apparatus for transmitting video

Abstract

A method of transmitting a coded media frame comprises determining a plurality of media frame sizes including a media frame size, transmitting an element comprising the plurality of media frame sizes, and thereafter receiving an input media frame. The method also includes processing the input media frame according to the media frame size to provide a coded media frame, and transmitting the coded media frame.

         22 . A method of iteratively encoding one or more macroblocks in a video frame reusing motion estimation information, the method comprising:
 encoding the one or more macroblocks using a first quality parameter, producing one or more coded macroblocks, one or more motion vectors for the one or more macroblocks and a bitstream size associated with at least the one or more coded macroblocks;   determining a second encoding is to be performed based in part on a target bitstream size;   providing a second quality parameter; and encoding the one or more macroblocks using the second quality parameter and the one or more motion vectors, producing one or more second coded macroblocks.   
     
     
         23 . The method of  claim 22  wherein determining a second encoding is to be performed utilizes a desired bitstream size, the bitstream size and a threshold. 
     
     
         24 . The method of  claim 22  wherein encoding the one or more blocks using the second quality parameter and the one or more motion vectors is performed without a motion estimation process. 
     
     
         25 . The method of  claim 22  wherein the second quality parameter is less than a certain distance away from the first quality parameter.
