With more than 200 exhibitors, this year's show is three times the size of last year's inaugural event. This year, cinema in the home is a major theme - with half a dozen systems on display. The idea is to bring cinema-quality images and sound into the living room. The single-unit systems, with speakers at the back of a room behind the audience as well as to the side and on top of the screen, are beginning to find a market in the UK.
The rise in popularity of home cinema has been described as the death of the hi-fi, with a single combined entertainment system taking its place. But hi-fi companies are fighting back. Linn, the loudspeaker company, showed its 'multi-room' system, which wires up the whole house or flat so the occupants can control the sound in each room separately from one central panel.
The system can be programmed to play a CD in the living-room, the radio in the bathroom and a cassette in the kitchen. This flexibility costs about pounds 1,000 per room; the first system went to the Prince of Wales, for Kensington Palace.
Sharp launched its Teleport video modem, which can send colour video stills down a telephone line. After shooting a home video, the operator plugs the camcorder into the Teleport, selects a frame and sends it over to a friend's Teleport.
The company also showed its 21-inch 'hang-on-the-wall' television - one of the largest liquid crystal display screens developed. The company has just begun mass production of 10-inch flat screen displays in Japan, and hopes to aim its larger versions at the rapidly expanding multi-media market - computing that combines text with graphics, video and sound.
Novell launched a new range of word processing software for children, also aimed at exploiting the rise of personal computing in the home. The company expects 1.5 million multi-media computers to be sold in the UK this year.
Other gadgetry on show included Canon's new auto-focus camcorder, which fires an infra-red beam at the retina to track the operator's eye movements. Swatch showed its new combined wrist-watch and pager to be launched next month, and Bose launched the 'Wave Radio' - a radio alarm that can be programmed to switch on to different channels at different times.
