Control information for a wirelessly-transmitted data stream

A non-transitory computer-readable memory medium comprising program instructions, wherein when executed by a device, the program instructions cause the device to:

• transmit a first plurality of packets, the first plurality of packets comprising a multimedia stream according to a first service type, first control information, and a first data structure, wherein the first data structure comprises information about the first control information, wherein the first data structure specifies that the first control information is associated with the first service type;
• modify the first data structure to include additional information about second control information, wherein the modified first data structure specifies that the second control information is associated with a second service type, wherein the modified first data structure retains the information about the first control information;
• and
• transmit a second plurality of packets, wherein the second plurality of packets comprise 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,
• wherein the first data structure is separate from the first control information.

A device, comprising:

• a transmitter;
• a memory medium;
• and
• a processor operably coupled to the transmitter and the memory medium;
• wherein the processor, memory medium, and transmitter are configured to:
• transmit a first plurality of packets, the first plurality of packets comprising a multimedia stream according to a first service type, first control information, and a first data structure, wherein the first data structure comprises information about the first control information, wherein the first data structure specifies that the first control information is associated with the first service type;
• modify the first data structure to include additional information about the second control information, wherein the modified first data structure specifies that the second control information is associated with a second service type, wherein the modified first data structure retains the information about the first control information;
• and
• transmit a second plurality of packets, wherein the second plurality of packets comprise 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;
• wherein the first data structure is separate from the first control information.
