Abstract
There is disclosed in aspects of the invention a method of evaluating the profit of a substream of encoded video data, a method of operating servers, a network and an apparatus. In the method, a data portion is identified comprising at least some of the data in the substream being evaluated; comparing a decoded version of the video with the data portion present and a decoded version of the video with the data portion removed and calculating an error metric indicative of the distortion between the two versions; and, calculating a profit for the substream dependent upon the error metric.
