Systems exist that allow video media such as movies to be distributed on a peer to peer network, but peers may not all require the same format mix of video, audio, language and subtitles. A video server connects to a peer-to-peer network and provides the network a signal having at least a separate video signal component and a separate audio signal component, these components being divided into a plurality of parts suitable for propagation over the network. A peer A (Fig. 4a) may request standard definition video, surround sound and subtitles, which are delivered as an interleaved stream of packets divided into parts A1, A2. Similarly peer B may require high definition video and stereo audio, which is delivered in as parts B1, B2. Another peer may later acquire the same programme by obtaining video from peer A and audio from peer B. Packet sizes and quantities will vary depending amount of information contained.
