<p>The present invention relates to an apparatus and method for distribution of a streamed signal within a group of users in a computer network, the users accessing client terminals (10, 20, 30, 40) for participation in a multicast session. The apparatus comprises connecting links (12, 22, 32, 42) adapted to connect the client terminals of users and related equipment, such as capturing means (16, 26...; 18, 28...), to the multicast session, preferably via the Internet or other interconnecting network. An extension header is added to data packets of the streamed signal, the extension header comprising identification data relating to the intended recipient of a packet. The invention is characterised in that a filtering means (14, 24, 34, 44) is associated with the receiving client adapted to filter out data packets having the address of the recipient and receiving the streamed signal. Consequently, the existing communication channel can be reused.</p> |
