Sony previews multi-channel machine

Sony is to begin selling a combination personal computer and video server that can record up to seven channels of television simultaneously, it said last week at the Ceatec 2004 exhibition. The machine will hit Japanese shelves in November.

To understand the Vaio X computer it's best to think of it as three things packed into one black, shiny box.

On one side it's a multimedia personal computer, with two 250GB hard-disk drives and a television tuner. Users can do all the normal things they would with one of the company's Vaio computers including recording television programs from a single analog channel or, via an optional unit, a digital TV channel.

Also packed into its tower-PC sized case are two video server boards. Each unit contains three analog TV tuners and is connected to a 250GB hard-disk drive.

The unit ran on the Micro iTron operating system and the interface with the rest of the PC via an Ethernet port, senior product producer at Sony's IT and mobile solutions network department, Junji Tsuyuki, said.

The three analog tuners meant it was possible to record three channels at once and because there were two server boards this rises to six channels simultaneously, Tsuyuki said.

With the tuner from the PC side of the device also added, a user can record seven channels at the same time although the focus of the device is continuous, simultaneous recording of six programs via the dual video servers.

That works out well for the company's target audience of consumers because most areas of Japan are served by two public television channels and between three and five commercial TV networks.

The 250GB hard-disk drive space was enough to store five-and-a-half days worth of programming from each of the three channels assuming continuous recording, or one week's worth of programs assuming 19 hours per day of TV per channel, Tsuyuki said. What's more, users could specify 400GB drives for the video server units when they ordered the Vaio X. This would raise its total storage capacity from 1TB to 1.3TB.

Users can bring up a grid-like electronic programming guide (EPG) screen that, instead of looking forward, contains the past few days of television. Then, at the press of a button, any program can be watched on demand - a function Sony likens to a time machine.

"In America, TiVo is very famous but we don't have it in Japan," Tsuyuki said. "This is a kind of TiVo for Japanese users."

Sony has licensed technology from TiVo, and also holds a stake in the company, but none of its technology was incorporated into the Vaio X, Tsuyuki said.

The Vaio VGX-X90P goes on sale in Japan on November 20 and will cost about $US4700.
