8.10. TSC

8.10.1. Overview

The transport stream controller(TSC) is responsible for de-multiplexing and pre-processing the inputting multimedia

data defined in ISO/IEC 13818-1.

The transport stream controller receives multimedia data stream from SSI (Synchronous Serial Port)/SPI (Synchronous

Parallel Port) inputs and de-multiplexing the data into Packets by PID (Packet Identify). Before the Packet to be store to

memory by DMA, it can be pre-processing by the Transport Stream Descrambler.

The transport stream controller can be used for almost all multi-media application cases, example: DVB Set top Box,

IPTV, Streaming-media Box, multi-media players and so on.

The Transport Stream Controller (TSC) includes the following features:

 Supports industry-standard AMBA Host Bus (AHB) and it is fully compliant with the AMBA Specification, Revision

2.0. Supports 32-bit Little Endian bus.

 Supports AHB 32-bit bus width

 One external Synchronous Parallel Interface (SPI) or one external Synchronous Serial Interface (SSI)

 32 channels PID filter

 Multiple transport stream packet (188, 192, 204) format support

 SPI and SSI timing parameters are configurable

 Hardware packet synchronous byte error detecting

 Hardware PCR packet detecting

 Configurable SPI transport stream generator for streams in DRAM memory

 DMA is supported for transferring data

 Interrupt is supported

 Support DVB-CSA V1.1 Descrambler
