Abstract
A data processing system for calibrating a media codec comprising a sequence of time-stamped frames and comprising: an encoder subsystem configured to perform encoding in accordance with one or more encode parameters; a decoder subsystem; and a calibration system comprising: a data store for storing an encoded media stream; and a calibration monitor configured to, on the media codec entering a calibration mode, cause: the decoder subsystem to decode the encoded media stream so as to generate a decoded media stream; the encoder subsystem to re-encode said decoded media stream; and the re-encoded media stream to pass back into the decoder subsystem; the calibration monitor being configured to, through variation of the encode parameters of the encoder subsystem, identify maximal encode parameters corresponding to the greatest steady-state demand on the media codec that permits decoding of the sequence of time-stamped frames at a rate in accordance with their associated timestamps.
