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.

Description

technical field [0001] The present invention relates to mobile television broadcast systems, and more particularly, in one embodiment, enhancements to the current ATSC digital TV broadcast system that provides mobile services to mobile and handheld devices. Background technique [0002] The ATSC (Advanced Television Systems Committee) standard refers to the digital television format that will replace the analog NTSC television system. The ATSC standard is a high-definition television standard that produces standard 4:3 or widescreen 16:9 images up to 1920 x 1080 pixels (more than six times the display resolution of earlier NTSC standards). The ATSC standard provides for the transmission of multiple standard definition "virtual channel" broadcasts on a single 6MHz TV channel. The ASTC standard also includes "cinema-quality" audio using the Dolby Digital AC-3 format to provide 5.1-channel surround sound. The ATSC standard also provides numerous ancillary data broadcast servi...
