New encoder offers anti-taping function
Texas Instruments is sampling a digital encoder for consumer electron-ics equipment that cost-effectively supports regional standards including the NTSC and PAL standards. The TMS320AV410 is well-suited for digital set-top boxes, DVD players and multimedia PCs. It implements the Macrovision anti-taping function, which many content providers now require in consumer electronics, and will be targeted at those manufacturers who are official Macrovision licensees. Alternatively, for applications where Macrovision anti-taping is not supported, the functionally equivalent TMS320AV411 is available. To provide system design flexibility, the 'AV410 supports numerous data input/output formats. For example, the user can input on a single port either multiplexed digital RGB or YCbCr data. Or, in accordance with the CCIR601 specification, the luminance and chrominance data can be de-multiplexed and input via two separate data ports, i.e. Y, CbCr. Three on-chip 9-bit DACs enable the user to independently select three different analog data output formats, RGB, Y/C (S-video) or composite video. Although the 'AV410 outputs analog data, all processing is performed digitally, thereby maximizing the quality of the video. Samples of the devices are available now with production scheduled for 4Q96.
