As consumer electronic devices increasing move to digital inter-faces, there remains the requirement to support legacy inter-faces such as composite video signals. This includes over-the-airbroadcast, cable, and VCR inputs to end-equipment such as digi-tal TVs, DVD-Recorders, and others. The quality of the videofrom these sources will be increasingly critiqued and becomemuch more visible on larger, digital video displays. With thisshift, it is imperative that providers of these end-equipmentschoose the right analog to digital video decoder.
Texas Instruments (TI), a worldwide leader in High-PerformanceAnalog products, has been developing video decoder productsfor almost a decade and has an extensive portfolio of decoders.These decoders provide competitive features that fit numerousend-equipment requirements.
In the pages that follow, you will learn more about TI’s Mixed-Signal Video devices and how each of these meet the demand-ing video quality, power consumption and flexibility require-ments of numerous consumer electronic products.

With a picture quality that has no rival, digital televisions areeclipsing analog models as the television of choice. The digitaltelevision market is surging as the world continues to acceleratethe transition from analog to digital TV transmission.
Digital tuners are being integrated into the sets, allowing con-sumers to experience the picture and sound quality of the digitalworld. Crisp, vivid pictures and the overall experience of digital TVare convincing a growing number of consumers to go digital.Technology also is improving the way the digital picture is deliv-ered. As a result, sales of digital television sets are beginning tosoar. Researchers estimate that 3.4 million digital TV units whichinclude high-end CRT (>29”), LCD, Plasma displays and DLPTM and30.6 million set-top boxes will be sold around the world in 2004.By 2008, 17.6 million digital TV units and 100 million set-topboxes are expected to be sold.
The improved picture of digital television can be attributed to thedevelopment of the 3DYC comb filter. Using a three-frame filter, itlooks at a cube of pixels of the chroma and luma signals formotion instead of a square of pixels that a 2D comb filter wouldscan. The improvement of 3D filtering is dramatic, especially onhighly detailed images or screen displays that use sharp graphicsthat can confuse conventional 2D filters.

TVP5160 5
3D Comb-FilterNTSC/PAL/SECAM Video Decoder
Texas Instruments’ (TI) newest addition to an already marketproven portfolio of video decoders provides an unparalleled videoquality to cost advantage never found in other decoder devices.The TVP5160 device, a high-quality, high-performance digital videodecoder (NTSC/ PAL/SECAM) digitizes and decodes all popularbaseband analog video formats into digital component video.
By implementing a 3D comb filter, the TVP5160 provides the highest quality video available today. The 3D comb filter, whichseparates the composite signal into both Y and C channels toreduce both cross-luma and cross-chroma artifacts, is applied onboth NTSC and PAL video inputs. Through a highly sophisticatedmotion detection algorithm, the TVP5160 successfully applies TI’spatented 2D, 5-line comb filter to those portions of the image thatare moving but also utilizes TI’s 3D comb filter to provide cleaner,crisper images to the static portions of the image.

6 DVD Recorder (DVD-R)
While video and audio quality, the amount of DVD content available and price declines drove the DVD player to become themost popular consumer electronics product ever, the DVD recorder(DVD-R) is about to follow the same path.
Introduced to the market in 2002, more DVD-Rs are appearing on the market, and prices are dropping to points that make them affordable for consumers. As more DVD-Rs are shipped, thelineup of features and increasing ease of use will continue tomake the products attractive to consumers. In 2007, more than50 million DVD-Rs are expected to be shipped throughout theworld.
Digital TV tuners, 1394 connectivity, electronic program guides,memory card slots, hard drives, high-speed recording capabilities,networking capabilities, DVD Audio, Super Audio CD (SACD) playback and write/rewrite capabilities will help drive consumerdemand for DVD-Rs. While DVD players typically sit alongside theVCR in most homes, integrating DVD-Rs into other products, such
as home theater in a box, television sets or even VCRs will alsohelp drive adoption rates for the machines.
In order for manufacturers to meet cost, performance, and otherregion specific needs such as video inputs and formats, it isimperative to choose components that meet these dynamic mar-ket requirements.

10 Security and Surveillance
Multicamera Security System Block Diagram
In today’s safety conscious world, video security and surveillanceis everywhere. In order to provide security to patrons and employ-ees, video security systems are being installed at a record rate.According to market research, the Digital Video Recorder (DVR)market is anticipated to grow over 10 million units by 2008.
Video systems generally support 4, 8, 16, or more video capturedevices. These requirements demand at least 4 video decodersper system. Due to the number of decoders needed, video quality,component size, and cost are key. Providers must delicately balance these features in order to provide the optimal solution. By providing an ultra-small (4x4mm) package and a competitiveprice, the TVP5150A is a perfect candidate for video security andsurveillance applications. In the future, TI will continue to providedevices that are focused on supporting this expanding market.
