Intel introduced a digital set-top box (STB) reference design at last week's Intel Developer Forum in San Jose, CA. The 815 Digital Set Top Box Reference Design is based on an Intel low-voltage Celeron processor along with the Intel 815 chipset with integrated 3D graphics, and supports embedded Linux operating systems.

Intel says the STB reference design enables low-cost solutions delivering IP-based video-on-demand and allows service providers to add capabilities such as voice over IP and residential gateway/access functions. The design is also said to be suitable for applications such as networked digital media recorders and personal video recorders.

The design is based on a compact (6.7 x 6.7 in.) single-board computer which includes the following features . . .

• Low Voltage or Ultra Low Voltage Intel Celeron processor — up to 866MHz CPU clock rate
• 168-pin DIMM memory slot for 64 to 512MB of SDRAM
• TV output: composite video, S-Video, DVI display port, NTSC, PAL, Component video (option)
• Audio: left/right output, SPDIF, RCA and Toslink
• 10/100 Mbps Ethernet port (on RJ45)
• Two USB 1.1 ports on external inteface connectors; two additional USB 1.1 ports on internal header connectors
• Infrared receiver for remote control or keyboard
• Two optional Mini-PCI module connectors (on back of board)
• Optional low-profile PCI expansion slot
• Two IDE drive interfaces
• DVD-ROM (IPV500 only): standard full size; DVD R/W optional.

Here are photos of the STB single-board computer (click each to enlarge) . . .
