DIVA Bi-directional Interface Technology Demonstrated to Work Over a Single CAT6 Cable GUANGZHOU, China, May 21
GUANGZHOU, China, May 21 /PRNewswire/ -- At the China Digital Living Forum
& Showcase 2008, the formation of the DIVA Consortium was formally unveiled to
the Chinese consumer electronics industry. The China Video Industry
Association (CVIA) announced its support of the DIVA Consortium's efforts to
create a new interface for next-generation interactive digital television and
consumer electronics (CE) networking. DIVA's interface technology promises to
combine uncompressed high-definition video, multi-channel audio, and
high-bandwidth, bi-directional data transfer over a single cable. Once
connected with DIVA, CE devices will be networked locally so they can be
easily set up and controlled from any TV on the DIVA network-passing video,
audio and bulk data between devices.
"We are excited that DIVA enables interactive digital TV and networking
among CE devices in future digital homes," said Mrs. Weimin Bai, Secretary
General of CVIA. "Combining uncompressed and compressed AV interfaces and
home networking with a secure, personal domain-based content-protection
technology will allow Chinese CE makers to take the lead in developing
products for a fully connected interactive digital home. We are especially
pleased that this next-generation interface technology is originating in China
and looking forward to becoming a successful global standard worldwide."
Key DIVA Technology Features
Unlike current industry interface standards, DIVA technology combines a
reliable, high-speed, bi-directional data channel with an uncompressed video
and audio channel to allow users to connect, configure and control various
home CE devices from their digital TVs.
DIVA technology enables an 8B/10B encoded forward channel for transporting
uncompressed video up to 13.5 Gbps, which is capable of handling video
transmissions well beyond 1080p resolution with deep color and high refresh
rates. In addition, DIVA enables a high-speed, bi-directional hybrid data
channel that can operate at up to 2.25 Gbps, and can be divided into
sub-channels that transport audio, command and bulk data. The protocol for
the hybrid channel can be bridged to other wired and wireless interfaces,
allowing DIVA interface products to easily connect to a home network that is
comprised of a variety of devices. At the China Digital Living Forum &
Showcase 2008, the DIVA protocol was demonstrated working over a single CAT6
cable, with only 8 wires (four differential pairs) to show its potential for
rapid and cost-effective adoption.
Major Chinese CE Companies Support DIVA
The DIVA Consortium's charter members (called the Promoters Group) include
major CE and home appliance manufacturers such as TCL Corporation; Chang Hong
Electric Co.; Skyworth Group; Hisense Electric Co.; Konka Group; Haier Co.;
SVA Information Industry Co.; Panda Electronics Co. and Synerchip Co., Ltd.
Ms. Weisong Gao, Director of R&D at Hisense said, "DIVA technology enables
compatibility with both existing wired and emerging wireless multimedia
interfaces. There are a number of issues regarding inter-device communication
that are difficult to resolve with today's wired interfaces. DIVA will
address these concerns so home networks can be set up to seamlessly utilize
both wired and wireless connections."
Dr. Weidong Huang, Senior Engineer of TCL said, "For consumer electronics
manufacturers, today's digital interfaces are point-to-point connections that
are limited in their ability to accommodate a network of devices. We look
forward to offering the ability to connect multiple source devices to multiple
displays, to monitor and control various digital home appliances from the TV
in the living room, and to organize various personal and mobile entertainment
devices in the same home network."
David Lee, Executive Chairman of Synerchip, and one of the chief
architects of the High-Definition Multimedia Interface (HDMI) notes, "By
merging multimedia and data communication over a single interface, the DIVA
standard is poised take digital home networking to a new level, fulfilling the
promise of making DTV the center of the home entertainment network."
