Product data sheet
the audio (left or right) input of the SAA7130HL for analog video decoding and direct audio
streaming to the sound card. On the other hand, the 2nd IF signal of the digital IF-PLL is
fed directly to the interface of the channel decoder (TDA10045), which decodes the signal
into a digital DVB-T Transport Stream (TS).
The SAA7130HL captures this TS via the dedicated peripheral interface into the
configurable internal FIFO for DMA into the PCI memory space.
The packet structure as decoded by the TDA10045 is maintained in a well-defined buffer
structure in the system memory, and therefore can easily be sorted (de-multiplexed) by
the CPU for proper MPEG decoding.
The Broadcast Driver Architecture (BDA) for Windows operating systems supports this
type of hybrid TV capture application, sharing one capture board for analog and digital
TV reception.
