Claim Text:
1. A device for encoding a video signal into an encoded video signal, the video signal including a sequence of images, the device comprising: a group of picture (GOP) adaption module that detects a high complexity scene in the sequence of images and that generates GOP adaption data indicating the high complexity scene when the high complexity scene is detected and that further detects a low complexity scene in the sequence of images and that generates the GOP adaption data indicating the low complexity scene when the low complexity scene is detected, wherein the GOP adaption module compares a scene complexity to a scene complexity threshold and detects the low scene complexity when the scene complexity compares favorably to the scene complexity threshold, and wherein the low scene complexity corresponds to more unified motion direction relative to the high scene complexity; and an encoding module, coupled to the GOP adaption module, that generates the encoded video signal with B frames that do not reference other B frames when the GOP adaption data indicates the high complexity scene and with at least one B frame that references another B frame when the GOP adaption data indicates the low complexity scene.
