The SAA7135 delivers exceptional picture quality and advanced video features proven in other SAA713x devices: low-noise, highquality ADCs, an adaptive comb filter, and subpixel-accurate scaling. Certified three-level Macrovision detection circuitry ensures the video content's original analog copy protection remains intact. Capture of transport streams from all digital TV broadcast standards supports hybrid TV designs; capture of MPEG datastreams from MPEG encoders supports time-shift applications. In PCI configurations, the SAA7135 takes full advantage of the streaming capabilities of PCs by outputting decoded video, audio,VBI, and transport streams through DMA bus-mastered writes across the PCI bus.
