Patent ID: 7817191

Claim:
A method for transmitting video data from a video camera on a data transmission line comprising the steps of: a. receiving said video data from said video camera at a first frequency; b. storing said video data in memory space within a first-in first-out memory until one-half of said memory space has video data from said video camera stored therein; c. transmitting said video data from said memory over said data transmission line as a serial data stream when one half of said memory space has video data stored therein, wherein said video data is transmitted from said first-in first-out memory over said transmission line at a second frequency; d. monitoring memory usage of said memory space within said first-in, first-out memory wherein a controller monitors said memory space within said first-in first-out memory; e. adding unused data words to said serial data stream wherein said controller determines when to add said unused data words to said serial data stream by monitoring the memory usage of said memory space within said first-in, first-out memory and then adds said unused data words to said serial data stream; and f. deleting unused data words from said serial data stream wherein said controller determines when to add said unused data words to said serial data stream by monitoring the memory usage of said memory space within said first-in, first-out memory and then deletes said unused data words from said memory stream.
