These single-chip solutions enable the host PC to perform audio/video capture, video display, audio playback, or record and playback at a later time through software or hardware audio/video codecs. The CX23880/3 integrates a 10-bit NTSC/PAL/SECAM composite and S-Video decoder, image resizer/scaler, Direct Memory Access (DMA) controller, and Peripheral Component Interface (PCI) bus master on a single device. As a PCI initiator, the CX23880/3 can take control of the PCI bus to stream data as soon as the bus is available. Analog video signals are input to the CX2388x via a four-input multiplexer. The device family captures and decodes all major terrestrial broadcast audio standards. The CX23880/3 series is fully compatible with Conexant's family of digital channel demodulators for capture of High Definition Television (HDTV) and Standard Definition Television (SDTV) streams, as well as broadband data over terrestrial, satellite, or cable links. A variety of third-party peripheral connectivity options are supported by the CX23880/3 series. Its General Purpose Input/ Output (GPIO) pins and CPU host port interface enable vendor-specific board functionality and marketplace differentiation. The CX23880/3 family offers a software solution for use with Windows XP Media Center Edition. It supports DirectX compliant device drivers for the following functions: Hardware MPEG encoding, Host-based MPEG encoding, Digital tuning, HDTV capture, Vertical Blanking Interval (VBI) data casting, Remote control receiving, and GPIO custom properties programming. The CX23880/3 video and broadcast audio capture chips are mixed-signal monolithic ICs that enable a new platform for video, audio, and data communications in the PC. The CX23880/3 family enables a board vendor to build a wide variety of analog and digital TV capture products from a common code base. Each has its own specific functions to support different applications.
