Digital Entertainment VES2750 VES2750 MPEG-2 Tr a n s p o r t Demultiplexer & Peripheral Contr o l l e r OVERVIEW The VES2750 VES2750 IC contains a MPEG-2 transport stream demultiplexer, DVB descrambler and a comprehensive I/O subsystem. When used with the companion VES6200 VES6200 MPEG-2 Decoder Controller chip, the two devices leverage the advantages of VLSI's advanced 0.2-micron mixed signal process technology, low-cost circuit packaging, and unified memory architecture to deliver a highperformance, low-cost digital video design solution easily adaptable to all major world broadcasting standards and delivery modes. The transport demultiplexer subsystem handles MPEG-2 transport streams of up to 60 Mbps (serial) or 7.5Mbps (parallel). It parses the streams to frame the MPEG-2 packets, and then routes the extracted packets to the VES6200 VES6200 as either video, audio, teletext, or data. The transport demultiplexer is based on a high-performance RISC engine. The flexibility and the filtering capabilities of the demultiplexer subsystem make it especially suited for high performance EPG filtering. This subsystem includes a DVB descrambler. The VES2750 VES2750 also performs Program Clock Reference (PCR) recovery to maintain audio and video synchronization. It features robust error handling with error source for interrupt status and interrupt mask. The I/O subsystem contains all major peripheral functions required for a set-top box. The VES2750 VES2750 contains an interface to IEEE 1394 Link ICs. It also contains a slave IEEE 1284 interface, two I2C masters, two 16-bit counter-timers, 32-bit free- Block Diagram Channel Data Packet Packet Framer Framer FIFO FIFO 256 x 8 256 x 8 Transpor tt Transpor 16-bit RISC 16-bit RISC CPU CPU PCR Recover y PCR Recover y Hardware Filtering Hardware Filtering IEEE 1394 IR I/O DVB DVD Descrambler Descrambler Queue Queue Manager Manager Embedded SRAM Embedded SRAM Video Video Interface CRC Processor Processor IEEE 1394 IEEE 1394 Interface Interface Audio Audio Interface Interface 2 IR 2 IR Capture Capture & Blaster & Blaster Audio Audio Tone Tone LNB LNB Timer Timer Inter rupt Inter rupt Controller Controller Modem Modem Codec Codec Interface Interface 2 UART 2 UART 1 SPI 1 SPI 2 II22C II22C 2 C 18 GPIO 18 GPIO 2 Smartt 2 Smar Card Card Interface Interface Interrupts Codec I/O Smart Card 2x 2x 16-bit 16-bit Timers Timers DMA to DMA to VES6200 VES6200 VES6200 VES6200 Teletext Teletext Interface Interface Audio Video Teletext Free Free Running Running 32-bit 32-bit Counter Counter IEEE IEEE 1284 1284 Interface Interface IEEE 1284 External External Bus Bus Interface Interface Host Interface running counter, two IR capture ports, IR blaster, master SPI interface, two full-duplex UARTs, two ISO-7816 ISO-7816 compliant smart card interfaces, LNB timer, audio tone generator, interrupt controller, telephone modem codec interface, GPIOs, and a watchdog timer.
