System and method for wireless broadcast of multimedia files to vehicles
First Claim
1. A system for broadcasting multimedia files to vehicles, said system comprising:
- an encoder configured to convert a multimedia file to a group of encoded data packets; and
a wireless transmitter coupled to said encoder, said transmitter configured to receive said group of encoded data packets from said encoder and concurrently broadcast at least one group of encoded data packets for a pre-determined time period and at a pre-determined data rate, each of said at least one group of encoded data packets corresponding to a different multimedia file, said time period based on an average vehicle operation duration, said data rate based on a broadcast bandwidth and a number of concurrently broadcasted groups of encoded data packets.

Abstract
Apparatus and methods are provided for wirelessly broadcasting large multimedia files to vehicles. The apparatus includes a vehicle-based receiver configured to wirelessly receive at least one group of encoded data packets at a data rate based on a number of concurrently broadcasted groups of encoded data packets, a decoder coupled to the data storage device, a data storage device coupled to the receiver, and a media playback unit coupled to the data storage device. The group of data packets corresponds to at least a portion of a multimedia content, and each of the data packets contains at least a portion of the multimedia content. The data rate is based on an average vehicle operation duration and/or a probability of occurrence of the average vehicle operation duration. The decoder is configured to assemble at least a portion of the multimedia content from the first data file upon the data storage device receiving a pre-determined number of data packets. The data storage device is configured to store the group of data packets and assembled multimedia content. The playback unit is configured to play the assembled multimedia content.
