A company formed in August 1994 by Acorn Computer Group
plc to exploit the ARM
RISC in television set-top box
decoders. They planned to woo British Telecommunications
plc to use the box in some of its video on demand
The "STB1" box was based on an ARM8
core with additional circuits to enable MPEG
to be decoded in software - possibly dedicated instructions for interpolation, inverse DCT
table extraction. A prototype featured audio MPEG
chips, Acorn's RISC OS operating system
and supported Oracle Media Objects
. Online planned to reduce component count by transferring functions from boards into the single RISC chip.
The company was origianlly wholly owned by Acorn but was expected to bring in external investment.

In 1996 they releasd the imaginatively titled "Set Top Box 2" (STB20M) with a 32 MHz ARM 7500
and 2 to 32 MB RAM
. There was also a "Set Top Box 22".
