摘要：
First control information, generated according to a first protocol version, for configuring an audiovisual device to present a multimedia stream, may be generated. A first data structure specifying that the first control information is of the first protocol version may be generated. A plurality of packets, including a multimedia stream, the first control information, and the first data structure, may be generated and transmitted. Second control information, generated according to a second protocol version, for configuring an audiovisual device to present a multimedia stream, may be generated. The first data structure may be modified to include information about the second control information. A second plurality of packets, including the modified first data structure, the first control information, a multimedia stream specified by the first control information, the second control information, and a multimedia stream specified by the second control information, may be generated.
