New Philips WiFi videophone runs Linux

Jan 18, 2007 — by LinuxDevices Staff — from the LinuxDevices Archive

Philips Consumer Electronics has registered a Linux-powered WiFi videophone with the FCC, for possible U.S. distribution. The Visiophone VP6000 and its earphone-jack- and TV-out-equipped sibling, the VP6500, run Linux on an ARM9-based Freescale i.MX21 processor, and feature vendor-initiated… firmware updates.

The company's earlier VP5x00 videophone (pictured at right) also ran Linux.

As with the VP5x00, the VP6x00 cannot function as a videophone without mobile carrier support, according to the draft manual submitted to the FCC. Thus, the device appears to be designed for distribution by broadband network operators, as part of a videophone services contract.

Philips's FCC registration materials for the Visiophone VP6x00 include test results suggesting that the device will support 802.11b/g WiFi and Bluetooth. The materials also include a draft user manual suggesting the device will support “802.11i” (WPA2 security extensions) and “802.11e” quality-of-service (QoS) enhancements.

The 32-page draft user manual suggests that the VP6x00 phones have a limited feature set, possibly to reduce operator support costs. However, the phone does have a few Linux- and Qtopia-like features, such as a user-customizable themes.

One of the more interesting features from a device maker's point of view is an automatic “push” software update capability. The update “typically takes place only at night,” according to the draft manual, and “only if you are not using the phone.” It takes about three minutes.

Another interesting feature is a camera that rotates 240 degrees. A sensor detects the VGA-resolution CMOS sensor's orientation, and flips the image as needed.

The VP6500 model adds a small sideflap (shown below) that covers a headphone jack and TV out jack for CIF (352 x 288) video.

What's under the hood?

The VP6x00 is based on a Freescale Dragon Ball i.MX21 processor (MC9328MX21VK). The processor integrates an ARM9 core, clocked between 266 and 400 MHz.
