Abstract
A system and method for wirelessly transmitting audiovisual information. First audiovisual information may be encoded using a first error correction coding method. A plurality of packets may be generated, including the first audiovisual information, second audiovisual information, and control information. The second audiovisual information may not be encoded using the first error correction coding method, and the control information may indicate this. The plurality of packets may be wirelessly transmitted. The control information may be usable by a receiver to determine that the second audiovisual information is not encoded using the first error correction coding method, and may thereby determine that the second audiovisual information is a different service version than the first audiovisual information.
