SAA7135

· Fully automatic standard detection and decoding of worldwide analogTV video formats (PAL, NTSC, and SECAM), and worldwide TV stereo formats (A2/Dual-FM, NICAM, BTSC with dbx™, SAP, EIAJ, and FM radio)
· Advanced audio feature processing including Dolby® Pro Logic™, Virtual Dolby Surround™, Philips Incredible Sound, and more
· Supports simultaneous stereo decoding and adaptive 3D comb filtering (to enhance picture quality)
· Certified three-level Macrovision® detection circuitry
· Captures raw VBI data (for Closed Captioning,Teletext, etc.)
· Superior subpixel-accurate horizontal and vertical scaling
· Outputs digital I²S audio and ITU-656 video
· Captures transport streams from digital TV broadcasts and MPEG datastreams in time-shift applications
· For PCI (Rev. 2.2, ACPI compliant) and standalone configurations

The SAA7135 is targeted for adding multi-standard analog TV decoding with robust audio features to computing and consumer products such as desktop and portable PCs, hybrid TVs or set-top boxes (cable, terrestrial, satellite), personal video recorders (with time shifting), DVD recorders, and more.

Like other SAA713x single-chip TV decoders, the SAA7135 offers high-quality detection and decoding of all worldwide analog TV video standards. In addition, it decodes all worldwide TV stereo formats and supports advanced audio features, such as Dolby Pro Logic decoding, and more. The SAA7135's flexible design, reusable components, and versatile external interfaces lower BOM and cost and support advanced TV decoder configurations. It gives manufacturers an ideal solution for adding robust multi-standard analog TV decoding to a wide variety of computing and consumer products. In addition, the SAA7135's 100% pin compatibility with existing SAA713x decoders enables efficient reuse of existing SAA713x designs for more sophisticated markets or price points.

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.
