ABSTRACT:
Transcoder multiplexers that transport digital packets, such as MPEG2 packets, between boards in a chassis using a serial differential protocol are disclosed. The disclosed multiplexers achieve data transfer rates at least twice as fast as conventional systems. Digital data packets are thereby efficiently communicated to target processing engines on other boards across the backplane. Prior art requirements for custom backplane designs, together with discrete hardware for sending data in parallel form between boards, are obviated. Instead, a backplane architecture designed specifically for IP data traffic from any slot to any slot is utilized. Also, an improved protocol is applied for transmitting data serially between boards to provide an inexpensive, upgradeable and flexible hardware solution. Preferred embodiments use LVDS transmitter/receiver pairs with high link speeds.
