Abstract
A system for structuring information outputted at a variable bit rate from a video signal encoder and for organizing the information into information units or packets. The information packets are compatible for transmission and processing by packet transmission networks such as asynchronous transfer mode (ATM), capable of sending transmission data streams at variable speed. In a preferred embodiment, the system uses an encoder that comprises video units. Each video unit contains information classified into three distinct classes. Each video unit is associated with a video packet comprising a header and a body. Each of the three distinct classes of information associated with a video unit uses a different technique for tho providing protection of that information against transmission errors and/or information packet loss.
