Abstract:
In one embodiment, a video encoder generates an encoded bitstream representing a sequence of video frames including a keyframe. The encoder generates information for use by a decoder that receives the encoded bitstream to enable the decoder to generate display frames from a pre-keyframe video frame that is prior to the keyframe in the sequence of video frames. The encoded bitstream is sent to the decoder. In another embodiment, a video decoder receives from an encoder an encoded bitstream representing a sequence of video frames including a keyframe. The keyframe includes information to enable the decoder to generate display frames from a pre-keyframe video frame that was received prior to the keyframe in the sequence of video frames. The decoder generates display frames using the pre-keyframe video frame, information included with the keyframe and information included with an encoder-determined number of decoded frames subsequent to the keyframe.
