Method and arrangement for video transcoding using mode or motion or in-loop filter information
First Claim
1. A method of transcoding of a video bitstream performed by a transcoder, comprising:
- receiving a video bitstream with a predetermined input video format;
receiving side information related to said video bitstream, said side information comprising at least one of mode or motion or in-loop filter information relating to another predetermined output video format, different from said predetermined input video format, for said video bitstream;
decoding said received side information to generate transcoding guiding information; and
encoding a representation of said received video bitstream based at least on said generated transcoding guiding information, to provide a transcoded video bitstream with a predetermined output video format.

Abstract
In a method of transcoding of a video bitstream by a transcoder arrangement, performing the steps of receiving a video bitstream with a predetermined input video format, receiving side information related to the video bitstream, the side information comprising at least one of mode or motion or in-loop filter information relating to at least one other predetermined video format for the video bitstream. Further, performing the steps of decoding the received side information to generate transcoding guiding information, and encoding a representation of the received video bitstream based at least on the generated transcoding guiding information, to provide a transcoded video bitstream with a predetermined output video format.
