Abstract
Methods and systems are provided for streaming a media asset with an adaptive bitrate transcoder. A server receives, from a client device, a first request for a first portion of the plurality of portions to be transcoded at a first bitrate. The server then starts to transcode the plurality of portions at the requested first bitrate to generate a plurality of corresponding transcoded portions. The server updates a header of a transcoded portion to include: 1) a transcode latency value; and 2) a count value indicating a number of available pre-transcoded portions of the media asset at the time the first request was received. The server then transmits the transcoded portion to the client. The client device then determines a second bitrate based on the transcode latency value included in the header of the transcoded portion corresponding to the first portion.
