Local Loop Bonding Used for HDTV over ADSL

Net to Net Technologies and TANDBERG TV demonstrated an HDTV over ADSL capability using a local loop bonding mechanism to combine the bandwidths of two ADSL lines. Net to Net's ADSL Loop Bonding technology was used to provide aggregated bandwidth of just over 21 Mbps by combining two ADSL lines. One HDTV MPEG-2 stream, encoded at 15 Mbps, and one standard definition MPEG-2 stream, encoded at 3 Mbps, were simultaneously transported over the bonded ADSL lines. The test simulated a typical household within 10,000 feet of the telephone company central office or remote terminal.


TANDBERG TV said its MPEG-2 video processing technology enables standard definition video channels at bit-rates in the 2-3.5Mbps range, while MPEG-2 high definition video channels typically require 10-15Mbps today.
