Abstract
An image data transmission system includes mobile transceivers having memories storing image data that is organized in sequential blocks. The mobile transceivers sequentially pass by a stationary transceiver and pause proximate the stationary transceiver. While pausing, a mobile transceiver transmits a block of the image data to the stationary transceiver, which receives and stores the transmitted data. Data transmission is interrupted by movement of the formerly pausing mobile transceiver. The stationary transceiver transmits a pointer signal to a paused mobile transceiver indicating which blocks of image data have been stored in the stationary transceiver so that the mobile transceivers transmit the blocks sequentially until all blocks have been received and stored by the stationary transceiver. The apparatus may be employed in a mass transit system, such as a subway or commuter train, in which the mobile transceivers are mounted in train cars and the stationary transceiver is located at a station. The image data may be used to illuminate electronic displays in the station each time all of the blocks of data have been transmitted to and stored in the stationary transceiver. Thus,…
