ABSTRACT:
A unique packet format is disclosed including a unique transport word, i.e, header, and a number M of relatively short-fixed length information words. The transport word includes a packet size field indicating the number M of information words in the packet and a field indicating the number of bytes of information in the last word of the packet. Additionally, the transport word includes a field which indicates whether the number M of information words in the packet is greater than zero. If the number of information words is not greater than zero, any user information being transported is in a predetermined field in the transport word. In one example, the size field in the transport word is used to transport the user information when the number of information words is indicated as being zero.
