VORRICHTUNG UND VERFAHREN ZUR TRANSKODIERUNG VON VIDEOSIGNALEN |
摘要 |
A method of transcoding coded video signals and a corresponding device for implementing this method are described. The device comprises decoding and encoding sub-assemblies (201, 202) and, within the encoding sub-assembly, quantizer (23) and bitrate controller. This bitrate controller comprise, before the quantizer (23), circuit for computing a local target value for encoding each sub-picture of the images to which video signals correspond and circuit for controlling the step size during the quantizing step. |
