A video data decoding apparatus configured to decode input encoded data representing a plurality of independently decodable portions of a video image, each portion representing a spatially subsampled version of the video image so that a combination of the plurality of portions provides a representation of all of the pixels of that video image, each pixel being represented by only a respective one of the portions, and at least one portion providing a subsampled representation of the entire video image, comprises: one or more decoders having a collective processing capacity which is lower than the maximum possible processing requirements for decoding the plurality of portions; a controller configured to route data of the portions to the one or more decoders so that, in the event that the processing requirements for the plurality of portions in respect of a video image exceeds the collective processing capacity of the one or more decoders, the one or more decoders cooperate to decode the whole of at least one of the portions for that video image; and a combiner configure to combine the decoded portions to generate a representation of that video image. |
