Data is transferred to the port through an on-chip pair of 512-byte-deep
FIFOs. This feature supports the MPEG-2 system layer requirement,
dedicating a 512-byte transport buffer to each one of the PES elementary
streams. This feature makes it possible for low-cost applications to use
the device without needing external DRAM memory. The chip can handle
three back-to-back packets coming to the channel at 60 Mbits/s. The
architecture allocates one transport buffer’s FIFO to serve PES data
coming on PID Index 30 (audio), and the other to serve data coming on
PID Index 31 (video).
In normal operation, the output data from the PID Post-processor is
transferred directly to the transport buffers’ FIFOs. Some applications,
however, allow using the extended channel mode option; this routes PES
streams coming on PID Index 30 and PID Index 31 rst to the external
DRAM, and then to the transport buffer FIFOs (see Figure 2.50). This is
very useful for systems with much jitter in the data transfer rate. You must
allocate buffer space in the memory for the extra data.
