Generating control information for use in transmission with a multimedia stream to an audiovisual device
First Claim
1. A method for generating control information for use in transmission of a data stream to a wireless receiver device, the method comprising:
- generating first control information, wherein the first control information is for configuring the receiver device to decode a wirelessly received data stream, wherein the first control information is generated according to a first protocol version parameter and a first physical layer parameter;
generating first data, wherein the first data includes said first protocol version parameter and said first physical layer parameter indicating a physical layer structure of the first control information;
transmitting the first control information, the first data, and a first plurality of packets that include information specifying at least one data stream;
generating second control information, wherein the second control information is for configuring the receiver device to decode a data stream, wherein the second control information is generated according to a second protocol version parameter and a second physical layer parameter indicating a physical layer structure of the second control information;
generating second data, wherein the second data includes said second protocol version parameter and said second physical layer parameter indicating a structure of the second control information, wherein a value of said second physical layer parameter is different than a value of said first physical layer parameter, and wherein the physical layer structure of the second control information is different than the physical layer structure of the first control information; and
transmitting the second control information, the second data, and a second plurality of packets that include information specifying at least one data stream.

Abstract
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.
