Abstract
A device encodes a video signal having a sequence of images into an encoded video signal. The device includes 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. An encoding module generates the encoded video signal with hierarchical B frames disabled when the GOP adaption data indicates the high complexity scene.
Claims14
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
- an encoding module, coupled to the GOP adaption module, that generates the encoded video signal with hierarchical B frames disabled when the GOP adaption data indicates the high complexity scene.
A method for encoding a video signal into an encoded video signal, the video signal including a sequence of images, the method comprising:
- detecting a high complexity scene in the sequence of images;
- generating GOP adaption data indicating the high complexity scene when the high complexity scene is detected;
- and
- generating the encoded video signal with hierarchical B frames disabled when the GOP adaption data indicates the high complexity scene.
