SAA7135 For multi-standard analog and hybrid TVs, the Philips SAA7135 integrates high-quality decoding of all analog video and stereo formats used in TVs worldwide. It gives manufacturers a low-BOM solution for new PCI products, and an efficient upgrade path for adding advanced audio features to existing SAA713x designs. Single-chip, analog TV video/stereo decoder for worldwide PCI applications— with Dolby Pro Logic Semiconductors 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. Key features > Fully automatic standard detection and decoding of worldwide analog TV 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 Target applications 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. SAA7135 Single-chip, analog TV video/stereo decoder for worldwide PCI applications—with Dolby Pro Logic Semiconductors Analog TV video processing Capture Analog video is sampled through five video inputs, supporting any combination of CVBS and S-Video signals.The SAA7135 automatically detects 50- and 60-Hz field frequencies and all analog standards (PAL, NTSC, and SECAM) used in TV broadcasts. Video is digitized by sophisticated, low-noise nine-bit ADCs with built-in white and color peak control, clamping, and programmable gain control. 27-MHz oversampling, twice the ITU-601 standard, ensures an exceptional signal-to-noise ratio for maximum picture clarity. Additional video capture features include: > single crystal support for all video standards > ultra-fast frame lock for fast input-switching in surveillance applications and VCR fast search, shuttle, and freeze frame > forced-field toggle for use with non-interlaced inputs to avoid VCR ‘blue screen’ Decode The SAA7135 decodes composite video into ITU-601 compatible component color values. Its high-quality multi-standard adaptive four-line comb filter performs best-in-class luma/chroma separation of CVBS signals from all sources, significantly reducing dot crawl and enhancing image resolution and detail.The decoder integrates separate brightness-contrast-saturation circuitry for CVBS, S-Video, and raw VBI samples, and hue control for CVBS and S-Video signals. The SAA7135 supports fully automatic, three-level hardware Macrovision detection with active-status interrupt. By ensuring the content's original analog copy protection is still intact, Macrovision prevents unauthorized recording of copyrighted material transmitted through analog video outputs in applications such as time-shift or archive recording or large screen display.
