VIDEO STREAMING DEVICE AND METHOD OF CONTROL FOR SWITCHABLE VIDEO STREAMS

摘要

A method of controlling a video streaming device, comprising a switching means for switching between alternative data rate versions of one of a plurality of video streams. The switching means employs a plurality of switching methods. Switching method selection is controlled by data encoded within selected frames of each of the alternative data rate versions of the video stream. The encoded data indicates which if any of the plurality of switching methods to select at and/or after said selected frames for the desired video stream switch. This enables the vide streaming device to employ different switching method for each frame, enabling the reduction both of prediction errors after switching and data storage requirements.
