Abstract
A method for transmitting video information is shown, in which at least a first bit-stream () and a second bit-stream are formed. The first bit-stream () includes a video frame, and the second bit-stream () includes a predictive video frame (). Different encoding parameters are used with encoding of the frames of the first bit-stream () and the second bit-stream (). A frame of the first bit-stream () is transmitted, and the transmission is switched over from the first () to the second bit-stream () during which a secondary switching frame () is transmitted encoded using the encoding parameters of the second bit-stream () and at least one reference frame from the first bit-stream (). The secondary switching frame () is used as a reference frame in the reconstruction of the predictive video frame () of the second set of video frames.
