NXP SAA7231 Triple Mode PCTV Solution
NXP Semiconductors recently introduced the SAA7231, which is the world's smallest single-chip PCTV solution that supports worldwide broadcast standards. Packaged in half the size of a minicard, the NXP SAA7231 is 40% power-efficient, saves OEMs up to 15% of total BOM (bill-of-materials) cost, and speeds up time-to-market under one month. NXP's SAA7231 can be packaged into 10mmx10mm size with support for PCI / PCIe interfaces and is capable of consuming as little as 1.5Watts of power to ensure uninterrupted streaming of AV content with extended playback time. The SAA7231 is also supported by a device driver package for Microsoft's BDA (Broadcast Driver Architecture) for Windows Vista and XP.
NXP's SAA7231 is ideally suited for TV cards in current and future flavors of Microsoft Media Centre Edition (MCE) PCs, with support for analog, DVB-T and DVB-S broadcasts as well as an integrated MCE-compliant IR controller for a full-function remote control. A state-of-the-art video processing engine decodes the analog AV stream for features such as PVR and time shifting, while adaptive 2D noise reduction improves picture quality. The SAA7231 also includes certified three-level Macrovision® detection circuitry to keep the video's original analog copy protection intact, while premium TV content is protected through 128-bit AES and (T)DES encryption.
