Patent abstract
A signal stream is transmitted when an available transmission bandwidth becomes reduced by providing alternate signal streams of different bit rates from the same source. The alternate signal streams are sub-sampled to form frames that have particular identifiers added thereto. The server is informed in advance, before actually providing the frames, of the identifiers. Because the server knows the current bandwidth limitations and knows the identifiers of the frames, the server can pass for transmission only those frames of the alternate signal stream that can fit within the transmission bandwidth that is available.
