Abstract

Upon providing (101) message content (such as a remote control instruction) to be transmitted, and in conjunction with provision (102) of a plurality of different transmission characteristics (as correspond, for example, to different types of transmission) and a corresponding plurality of correlated recovery identifiers (103), a particular transmission characteristic is selected (104) and used to transmit (105) a joint message. In particular, in a preferred approach, the selected transmission characteristic (106) is used when transmitting at least a portion of the message content portion of the joint message while another part of the joint message carries the recovery identifier to thereby facilitate selection of an appropriate reception technique by a receiver when receiving the joint message.

Claims

1. A method comprising:

selecting from a plurality of different transmission characteristics a particular transmission characteristic based at least in part on at least a portion of message content to provide a selected transmission characteristic;

selecting from a plurality of different recovery identifiers a particular recovery identifier correlated to the selected transmission characteristic; and

transmitting from a transmitter a message comprising the selected recovery identifier and a message content;

wherein the message is configured to allow a receiver to configure itself in response to receipt of the message.

2. The method of claim 1 wherein selecting the particular transmission characteristic comprises selecting at least one of:

a plurality of candidate data rates;

a plurality of candidate spread spectrum practices;

a plurality of candidate carrier modulations;

a plurality of candidate carrier frequencies;

a plurality of candidate joint message formats;

a plurality of candidate data orders;

a plurality of candidate data inversion patterns.

3. The method of claim 1 wherein selecting the particular recovery identifier comprises selecting at least one of:

a particular data rate identifier;

a particular spread spectrum practice identifier;

a particular carrier modulation identifier;

a particular carrier frequency identifier;

a particular joint message format identifier;

a particular data order identifier;

a particular data inversion pattern identifier.

4. The method of claim 1 wherein the message content comprises, at least in part, an identifier for at least one of:

a transmitting platform;

a receiving platform;

a communication system;

a communication system user.

5. The method of claim 1 wherein transmitting the message comprises transmitting a contiguous aggregation of the message content and the recovery identifier as uniquely corresponds to the selected transmission characteristic.

6. The method of claim 1 wherein transmitting the message comprises transmitting a plurality of discrete messages.

7. The method of claim 1 wherein transmitting the message comprises serially transmitting data elements as comprise the message.

9. The method of claim 1 wherein the message content comprises remote control signaling.

8. The method of claim 8 wherein serially transmitting the data elements as comprise the message comprises serially transmitting the data elements via a wireless connection.

10. An apparatus comprising:

a transmitter configured to select from a plurality of different transmission characteristics a particular transmission characteristic based at least in part on at least a portion of message content to provide a selected transmission characteristic, the transmitter further configured to select from a plurality of different recovery identifiers a particular recovery identifier correlated to the selected transmission characteristic, the transmitter further configured to transmit a message comprising the selected recovery identifier and a message content;

wherein the message is configured to allow a receiver to configure itself in response to receipt of the message.

11. The apparatus of claim 10 wherein the plurality of different transmission characteristics comprise at least one of:

a plurality of candidate data rates;

a plurality of candidate conversion symbol sets;

a plurality of candidate spread spectrum practices;

a plurality of candidate carrier modulations;

a plurality of candidate bit inversion patterns;

a plurality of candidate carrier frequencies;

a plurality of candidate bit interleaving patterns;

a plurality of candidate bit patterns;

a plurality of candidate joint message formats.

12. The apparatus of claim 10 wherein the plurality of different recovery identifiers comprise at least one of:

a particular symbol conversion set identifier;

a particular spread spectrum practice identifier;

a particular carrier modulation identifier;

a particular bit inversion pattern identifier;

a particular carrier frequency identifier;

a particular bit interleaving pattern identifier;

a particular bit pattern identifier;

a particular joint message format identifier;

a particular data order identifier.

13. The apparatus of claim 10 wherein the message content comprises remote control signaling.
