Wireless system with variable training information based on device type
First Claim
1. A method for broadcasting audiovisual information in a wireless manner, the method comprising:
- storing training information in a memory;
generating a plurality of packets,wherein the plurality of packets comprise audiovisual information intended for one or more types of receivers;
wherein the plurality of packets comprises the training information, wherein an amount of the training information depends on time of transmission of the plurality of packets, wherein the amount is greater at times when mobile receivers are estimated to represent a greater proportion of receiving devices;
wherein at least one of the plurality of packets comprises first information which identifies a first training pattern of a plurality of possible training patterns, wherein the first training pattern specifies one or more locations of the training information in the plurality of packets;
wherein the first information is useable by the receiver to determine the first training pattern of the plurality of possible training patterns;
transmitting the plurality of packets on a signal modulated in the frequency domain in a wireless manner.

Abstract
A system and method for wirelessly transmitting audiovisual information. Training information may be stored in a memory. A plurality of packets may be generated, including the training information. The plurality of packets may also include audiovisual information. The plurality of packets may include first information identifying a first training pattern of a plurality of possible training patterns. The first training pattern may specify one or more locations of the training information in the plurality of packets. The first information may be usable by a receiver to determine the first training pattern of the plurality of possible training patterns. The plurality of packets may be transmitted in a wireless manner.
