METHOD AND TRANSCODING PROXY FOR TRANSCODING A MEDIA STREAM THAT IS DELIVERED TO AN END-USER DEVICE OVER A COMMUNICATIONS NETWORK

摘要

Methods and transcoding proxies for transcoding media streams are described. In one embodiment, a method for transcoding a media stream that is delivered to an end-user device over a communications network involves selecting (602) a transcoding technique for the media stream, transcoding (604) a portion of the media stream using the selected transcoding technique, streaming (606) the transcoded portion of the media stream to the end-user device, while the transcoded portion of the media stream is being streamed to the end-user device, detecting (608) a change in a condition of the communications network, selecting (610) a different transcoding technique in response to the change in the condition of the communications network, transcoding (612) a subsequent portion of the media stream using the different transcoding technique, and streaming (614) the transcoded subsequent portion of the media stream to the end-user device. Other embodiments are also described.
