Siemens of Switzerland is shipping three hardware/software reference designs for Internet protocol set-top boxes (IP-STBs). The STB-7100-series designs run Linux 2.6 on a SuperH-based processor, and support standard- and high-definition content, along with multiple access technologies, including DSL, cable, and… DVB-T (digital video broadcast — terrestrial).

Siemens's STB-7100 series comprises:

  • STB-7100 — standard definition H.264 IP-STB
  • STB-7110 — high-definition H.264 IP-STB
  • STB-7120 — high-definition H.264 IP-STB with integral DVB-T module

The STB-7100-series designs are based on ST's ST7100 SoC (system-on-chip), clocked at 300MHz. The SoC integrates Renesas's venerable ST40 SuperH core, long supported by Linux, with H.264 and WMV9 decoders, and a multiplicity of on-chip peripheral interfaces, including serial, ATA, and USB 2.0.

The STB-7100-series designs have 128MB of RAM, along with 32MB of dedicated video memory. They also come standard with 16MB of Flash.

I/O includes:

  • 10/100 Ethernet on RJ-45
  • Front-panel USB 2.0 host port
  • SCART (RGB and component) audio/video out
  • S-video (Hosiden) video out
  • Analog (RCA) and digital (S/PDIF) audio outs

The STB-7110 and STB-7120 add an HDMI Type A connector, while the STB-7120 also adds:

  • IEC 168-2 (female) 75 Ohm DVB-T antenna input
  • IEC 168-2 (male) 75 Ohm connector for RF loop-out

Additional touted features include:

  • Supports wireless USB dongles
  • SD or HDTV up to 1080i
  • MPEG-2 and MPEG-4 pt10/H.264 Video Decoder (DivX optional)
  • Video on Demand, Audio on Demand
  • Internal hard drive for PVR/time-shifting
  • Integrated DVB-T/C Receiver (Hybrid STB) with EPG (electronic program guide) for DVB Channels (STB-7120 only)
  • Embedded Web Browser (HTML, HTTP, HTTPS, DHTML, SSL, Cookie, Java Script)
  • Classical-, IP- and Video-Telephony
  • Internal Web server (TinyWeb)
  • Extensive codec support:

The Siemens Switzerland designs come with a Linux 2.6 OS, complete with an embedded web browser and client-server IP-TV user applications. Available third party software includes Myrio Interactive on-screen display (GUI) software, and TwonkyVision's UPnP-compliant Media Server.

Siemens Switzerland Spokesperson Patrik Vonlanthen stated, “Interest in online services and applications that are innovative, comfortably operated, and funny is high. Market analysts quantify the future potential [at] more than 20 billion Euro.”


The STB-7100-series designs appear to be available now, along with a variety of third-party applications and codecs.
