| PRODUCT INFORMATION APB 7202A nGene(R) MULTIMEDIA Jan/2005 APB 7202A nGene(R) Dual-Channel PCI ExpressTM Multimedia Controller The advanced PCI Express multimedia controller APB 7202A features dual-channel video/audio and transport stream capture capabilities, as well as audio output functions. The APB 7202A combines flexible buffer management with the benefits of the PCI Express point-to-point protocol to form a key component for creating the next generation of PC-based personal video recording devices for high definition, as well as analog video and audio content. The IC provides an extensive set of features and functional integration, which include two transport stream interfaces, two ITU 656 video interfaces, I2S and S/PDIF audio input and output interfaces. Serial EEPROM support for IDs and firmware, field upgradeable Complete set of DirectShow(R) compatible WDM and BDA drivers which supports consumer PVR applications such as - - - - ShowShifterTM, Microsoft Media Center(R), InterVideo Home TheaterTM, and CyberLink PowerCinemaTM. x1 PCI Express core with all power management features 1.5 V core supply, 3.3 V I/O Hardware support for - Time stamping - A/V synchronization Scatter gather DMA operation Glueless interfacing to Micronas' video decoders and DVB-T/ATSC demodulators Applications Dual stream hybrid (analog and/or digital) audio and video capture, playback, PVR, and time-shift applications with high picture quality, low latency and high throughput capabilities. - Picture-in-picture (PIP) support - Watch and record - Watch one stream while recording another - Watch and record two streams - Pause, fast forward, rewind live TV - Simultaneous interfacing to STB / analog cable and ATSC - FM radio - Support of various analog or digital audio and video inputs (DVD, VCR, camcorder) Interfaces and Functions 2 x10/8 bit ITU 656 interfaces 2 parallel or serial transport stream interfaces Multi-channel capable I2S audio I/O interfaces 2 S/PDIF input interfaces 1 S/PDIF output interface UART, JTAG I2C master/slave interface Embedded microcontroller for flexible resource management Features Two transport stream inputs for DTV including HD formats (ATSC, DVB-T) Interlaced and progressive analog video streaming support (480/525 i/p) ITU 601 HD input support up to 1080i VBI sliced and raw data streaming support Multi-channel compressed and uncompressed audio streaming PRODUCT INFORMATION APB 7202A nGene(R) Application (ShowShifter/MS Media Center) Jan/2005 DRX 3975D Demod AVF 491xA A/V Decoder AVF 491xA A/V Decoder DRX 3975D Demod S/PDIF Out S/PDIF In 656 Host Driver Structure APB 72xyA nGene(R) PCI ExpressTM Multimedia Controller Direct Show Filter Graph Analog Tuner Streaming Driver Demod Streaming Driver Crossbar Streaming Driver ATSC Tuner Streaming Driver (BDA) DVB-T Tuner Streaming Driver (BDA) RF Tuner DRX 396xA Digital IF I2S Host Base Driver Tuner DRX 396xA Digital IF 656 I2S 2 x 656 Video In 2 x TS In 2 x I2S Input 1 x S/PDIF In 1 x S/PDIF Out GPIO I 2C PCIe x 1 Aux L/R CVBS S-Video YPrPb Firmware Communication Microcontroller / Firmware Hardware Interfaces Buffer PCI Express Controller 6261-230-1x Fig. 1: Software architecture Fig. 2: Dual-channel TV tuner with PCI ExpressTM System Architecture and Software The embedded microcontroller manages the peripheral interfaces, interrupts, and the bandwidth allocation on the PCI Express interface, as well as the host communication. I/O interfaces autonomously stream through an internal buffer allowing flexible handling of bandwidth and latencies. A complete set of WDM and BDA drivers for integration into any Microsoft DirectShow filter graph is available. The layered driver concept comprises: Downloadable firmware for the microcontroller allows flexibility in hardware resource allocation. The host base driver implements the hardware communication, as well as buffer and interrupt management. The base driver provides an internal API to communicate with the upper level drivers. Streaming drivers interface to the base driver to pass communication requests to the hardware. They appear as filter blocks in a DirectShow Filter Graph. The filters include: tuner (analog and digital), capture (audio, video, VBI, transport stream), and crossbar.
