SAA7135
S e m i c o n d u c t o r s
Surround algorithm emulates true surround sound formats and
effects when only two speakers are available. Philips Incredible
Mono
adds stereo-like sound impression to monaural audio
signals. Philips Incredible Stereo
widens the stereo image,
immersing the listener in the screen action. Additional on-chip
audio features include volume, balance, bass/treble controls,and
automatic volume leveling (AVL).
Output
Decoded digital audio is streamed across the PCI bus or output
through the I
2
S port. Alternatively,it can be reconverted to analog
(by on-chip stereo DACs) and rerouted through the loop-back
cable to a sound card.
VBI capture
The SAA7135 captures raw VBI samples to memory, making them
available for decoding by software components.The VBI sampling
rate can be adjusted as needed by the data slicing software.
Supported VBI formats include Closed Captioning,Teletext,WST,
NABST, CGMS, and WSS.
Digital TV transport stream capture
For hybridTV applications,the SAA7135 supports capture of
transport streams from digital TV broadcasts (ATSC, DVB or BS-
Digital). After capture, transport streams are written to memory
across the PCI bus for demux and program stream decoding,
typically by software running on the system CPU.
Time-shifting and digital video recording support
In time-shift recording or personal video recording applications,
the SAA7135 supports capture of MPEG datastreams through a
glueless interface to a hardware MPEG encoder. Captured MPEG
streams are written to system memory or a storage device.
Versatile external interface
The SAA7135's flexible design,reusable components, and versatile
external interfaces lower BOM and support advanced decoder
configurations. Such flexibility is made possible, in part,through a
set of 28 general purpose I/O (GPIO) pins, initially dedicated to
interface with key onboard components to provide:
> a digital video port
> transport stream capture from a digital TV channel decoder
> MPEG datastream capture from an MPEG encoder
> an I
2
S digital audio output port
> peripheral interrupt input.
GPIO pins can be reassigned if dedicated functions are not needed
in a specific product configuration. In addition, unassigned pins
can be utilized for GPIO under direct software control.
DMA and configurable FIFOs
In PCI configurations, the SAA7135 uses DMA bus-mastered
writes to output captured video, audio,VBI, and digital TV trans-
port streams. Seven DMA channels share a common one-kB
FIFO. The ability to define optimal burst length and FIFO capacity
