Control information for configuring an audiovisual device to present multimedia content according to a first service type may be generated. A method may include generating first control information for configuring an audiovisual device to decode a multimedia stream, generating first data that indicates a structure of the first control information, and transmitting the first data and the first control information. The first control information may be generated according to a first protocol version. Second data and second control information may be similarly generated and transmitted according to a second protocol version. Disclosed techniques may facilitate receiving devices to determine whether they support received wireless transmissions and decode the transmissions based on the control information.

Control information for a wirelessly-transmitted data stream

Generating control information for use in transmission with a multimedia stream to an audiovisual device

Control information for configuring an audiovisual device to present multimedia content according to a first service type may be generated. A first data structure specifying that the first control information is associated with the first service type may be generated. A plurality of packets, including a multimedia stream according to the first service type, the first control information, and the first data structure, may be generated and transmitted. Second control information for configuring the audiovisual device to present a multimedia stream according to a second service type 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 according to the first service type, the second control information, and a multimedia stream according to the second service type, may be generated and transmitted.

Bit efficient control information communication techniques. Control information for configuring an audiovisual device to present multimedia content may be generated. The control information may be organized according to a tree data structure having a plurality of nodes. The control information may include commands for navigating the nodes of the tree structure to locate data values stored at leaf nodes of the tree structure. Some commands may have associated data fields. Each command, and each data field, may include bit portions of uniform length. A designated bit of command bit portions may have a first value indicating that the bit portion is a command, while a designated bit of data field bit portions may have a second value indicating the bit portion is a data field. The second value may be different than the first value.

Bit-efficient control information for use with multimedia streams

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.

Transmitting and receiving control information for use with multimedia streams

A digital television broadcast system with transmission and/or reception of digital television signals for improved mobile reception. The communication layers in the transmit and receive portions of the transmission system can be dynamically modified, e.g., based on usage patterns or current channel characteristics. The transmission system also provides for cross layer control, whereby parameters in various of the communication layers are analyzed to determine appropriate updates to the system configuration.
