Abstract
Video data formatting apparatus and method in which an input signal is converted (transcoded) into an intermediate compressed video signal, where the intermediate compressed video signal has a GOP format in which each GOP contains fewer pictures than a GOP associated with the input video signal. A metadata signal which indicates data defining coding decisions is derived from the input video signal. A data quantity allocation is generated to control the transcoding into the intermediate video signal, whereby each picture of the intermediate video signal is transcoded so as not to exceed a respective data quantity allocation.
