Abstract

The present invention provides such a data transmission system (100), which encodes and transmits video, audio and text information across a global computer network without the use of a personal computer, workstation or video capture card. The data transmission system (100) can also receive transmissions from other like systems and decode and display or play the information on the video, audio and text outputs included in each system. The hardware, protocol and driving software components of the disclosed system provide a method for transmitting live, real-time and stored video and audio signals across the global computer network. The method includes the steps of: receiving analog video signals from a video input source (10) at a video preprocessor (110), which converts the received analog video signals (114) into alternative video signals that are useful for further processing; storing the preprocessed video signals in video memory (142) for further processing, transmission and display; storing system software, including an operating system in program memory (144); processing the converted video signals using a system processor (130) running the system software for processing the converted video signals for direct streaming over a global computer network; transmitting the processed video signals directly over the global computer network using a digital system processor-implemented communications means (172); and displaying the video signals being transmitted on a display means (180).
