METHODS AND DEVICES FOR CODING, TRANSMITTING AND DECODING DIGITAL DATA

摘要

The method is applied to video data (VD) transmitted from a camera (K) to a computer (R1), accompanied by audio data (AD) from a microphone (MIK). Text information is entered via a keyboard (TA) and/or a mouse (MA). The computer is linked by cable or radio (UM) to another computer whose processor (P) decodes the received data. Each segment includes a synchronisation word (HDLC flag) followed by a 4-bit multiplex code field denoting the type of data to follow, a segment length field and an error detection/correction field.
