Description
The IBM STB130x0 A/V Transport/Decoders are
full function companion decoders, designed to allow
seamless integration with IBM’s Digital Set-Top Box
Integrated Controllers.
Advanced multiple stream applications are enabled
when an IBM STB130x0 chip is paired with one of
IBM’s Digital Set-Top Controllers. Applications
include decoding one stream for display on a TV
while decoding and recording another to a VCR, pic-
ture-in-picture support, or decoding/displaying one
stream on a TV, while storing another encoded
stream on a hard drive.
When using one of IBM’s STB Integrated Controllers
with one of the STB130x0 chips setup and control of
the companion decoder is simplified due to the
seamless interface to the PowerPC processor found
in the main controller.
The IBM STB130x0 decoders provide an MPEG
transport demultiplexer, MPEG video decoder and
an MPEG audio decoder. The STB13010 provides
the added functionality to decode Dolby Digital
Audio. The transport demultiplexer can receive
transport streams up to 160 Mbps. The video
decoder can decode MPEG-2 Main Profile video
packetized elementary streams. The audio decoder
can decode MPEG Layers I and II and Dolby Digital
(STB13010 only) packetized elementary streams.
The IBM STB130x0 products each contain two built-
in PLLs. One provides system clocks and the other
generates the audio sampling frequencies. Both
also function to support audio and video synchroni-
zation. Additionally, gen-lock is supported by
providing separate video and system time clock
inputs.
Both products of the STB130x0 family are 208 pin,
plastic quad flat pack (PQFP) package devices.
