5. The transit vehicle broadcast system of claim 1 further comprising:

closed circuit broadcast means for broadcasting said multimedia content to said plurality of passengers traveling in said cars of said transit vehicle, each of said cars of said transit vehicle having said closed circuit broadcast means.

6. The transit vehicle broadcast system of claim 1 wherein said wireless transmitting means further comprises:

means for converting said multimedia content to a predetermined wireless frequency.

7. The transit vehicle broadcast system of claim 1 further comprising:

second means for wirelessly transmitting located in said another one of said cars of said transit vehicle, for wireless transmitting said received multimedia content to a predetermined third one of said cars of said transit vehicle.

8. (canceled)

9. A transit vehicle broadcast system for wirelessly distributing multimedia content for broadcast to a plurality of passengers traveling in two or more interconnected cars of a multi-car transit vehicle, said transit vehicle broadcast system comprising:

a first storage device for storing said multimedia content, including a processing means to manage said stored multimedia content for transmission to a predetermined another one of said two or more cars of a multi-car transit vehicle;

a first transmitter connected to said first storage device for wirelessly transmitting said stored multimedia content to said predetermined another one of said two or more cars of a multi-car transit vehicle;

a receiver located in said predetermined another one of said two or more cars of a multi-car transit vehicle, wirelessly receiving said multimedia content wirelessly transmitted from said first transmitter; and

broadcast means, located in said predetermined another one of said two or more cars of a multi-car transit vehicle, for wirelessly broadcasting said received multimedia content to said plurality of passengers traveling in said predetermined another one of said two or more cars of a multi-car transit vehicle.

10. The transit vehicle broadcast system of claim 9 wherein said first transmitter further comprises at least one of:

a converter for converting said multimedia content to a predetermined wireless frequency; and

an amplifier for amplifying said multimedia content prior to transmitting said multimedia content to said another one of said two or more cars of a multi-car transit vehicle.

11. The transit vehicle broadcast system of claim 9 further comprising:

a second storage device located in said another one of said two or more cars of a multi-car transit vehicle for storing said wirelessly received multimedia content for broadcasting said multimedia content to said plurality of passengers traveling in said another one of said two or more cars of a multi-car transit vehicle.

12. The transit vehicle broadcast system of claim 9 further comprising:

an amplifier connected to said receiver, located in said another one of said two or more cars of a multi-car transit vehicle, for amplifying said wirelessly received multimedia content to produce an amplified multimedia content;

a second transmitter for transmitting said amplified multimedia content to a third one of said two or more cars of a multi-car transit vehicle; and
