It is a multifunctional PCI device based on the original Bt878/879 products. The Fusion 878A is pin-for-pin compatible with the Bt878/879, and adds enhanced performance capabilities in video and broadcast communication services. Fusion 878A addresses the current analog TV requirements as well as the evolving digital TV broadcast standards like ATSC (American Television Standards Committee) and DVB (Digital Video Broadcast). The Fusion 878A is PC 98 and PC 99 compliant. Also, Fusion 878A conforms to the Advance Configuration Power Interface (ACPI) and power management requirements outlined ex in the PCI Bus Power Management Specification 1.0. Fusion 878A integrates more of the external biasing circuitry, which Distinguishing Features reduces the overall bill of materials and improves performance characteristics of video and clocking. This enables customers to • Supports NTSC/PAL/SECAM video input develop cost-effective, yet flexible solutions addressing analog • Worldwide graphics controller compatibility on and digital video. • PC 98/99 compliant • ACPI and power management • Transport stream DMA for ATSC and DVB digital broadcast – 40 Mbps serial I/O – 20 MBps parallel I/O infotainment products ys te m s digital PCl Video Decoder Fusion 878A General Features Driver software is available to move transport packet Because Fusion 878A is fully compatible with the current Bt878/879, upgrading to requirements like PC 98/99 compliance is a minimal investment. Also, customers can standardize with one PCI video decoder to enable multiple configurations of TV to host memory using the Fusion 878A DMA engine. Therefore, building next-generation digital broadcast solutions on the proven Bt878 platform is easy and low risk since the software is incremental to existing Fusion software. an tS cards that address the broad spectrum of broadcast streams from a wide variety of digital demodulators requirements around the world. Because Fusion 878A is based on the Bt878/879, customers can continue PC 99 Compliance to support their products using one software code ACPI and Power Management Interface base, adding functionality by including additional Fusion 878A supports ACPI and the Power software modules.

A PCI bus analog video decoder is used for three primary PC solutions: video capture and editing, video teleconferencing, and television receiver cards. A video signal is generated by a video source, which can be a camera,VCR or TV tuner. The baseband video that goes into the PCI decoder is a simple analog signal that contains video analog data and video master on a single device. Like the Bt848A, the Fusion family can place video data directly into host memory for video capture synchronization data, which is used to display the picture properly at the receiving end. The details of applications and into a target video display frame buffer for video the signal depend on the video standard used — overlay applications. NTSC (National Television Standards Committee), PAL Analog Audio/Video in (Phase Alternate Line) or SECAM (Systeme Electronique Graphics Memory Analog and Digital Tuner source generates a vertical synchronization signal OFDM DVB Digital Audio/ Video In Couleur Avec Memoire). To transmit the picture, the an tS I 2C I 2S Fusion 878A System Memory PCI BUS ATSC MPEG II All Format Decoder (optional) Disk GPIO (VSYNC). This signal resets the receiver (PC monitor) so that it begins picture display at the top of the screen. After the VSYNC signal is sent, the video source scans the first line of the image. Once the scan line CCIR 601 Digital RGB Out Bt869 (optional) Composite and S-Video Analog RGB/VGA Digital television receiver for the PC is complete, the camera generates a horizontal synchronization signal (HSYNC), which resets the receiver so that it will display the next line starting at the left-hand edge of the display. For each line of Fusion Software Drivers the image, a scan line and a horizontal synchronization pulse are sent. The PCI bus attached to the video Windows 95 and Windows 98. With the VxD drivers, board decoder is the access mechanism, or hub, for this video developers can support products using either the Windows 95 information traveling to the PC. The need for broadcast ex Fusion offers a suite of widely fielded software drivers for or Windows 98 operating systems. VxD and WDM drivers provide data in the PC is a primary reason analog dedicated PC video capture, playback and display in accordance with Microsoft’s Video for Windows and Direct Show 2.0, respectively.

World Headquarters Ultralock™ and Scaling Support Fusion 878A, like the Bt848A, Bt878, and Bt879, utilizes Conexant’s patented Ultralock technology that locks to an incoming analog video signal. Ultralock is able to recognize unstable video signals caused by VCR headswitches or Fusion is able to scale the video image size both vertically and horizontally, using arbitrarily-selected scaling ratios. The X and Y dimensions can be scaled to one-sixteenth of full resolution. Vertical scaling is implemented with Conexant’s industry-leading 5-tap vertical filter.
