TrueView 5725
Multimedia Processor for HD PTV and LCD TV
The TrueView™ 5725 is a low pin count, low-cost of advanced and highly integrated Digital and Analog Video Display Processor providing the key features needed to design HD-READY, progressive scan or LCD Televisions. TrueView™ 5725 accepts interlaced or progressive video input and graphic input such as NTSC/PAL, 1080i/720p, and SXGA, etc. in both analog and digital channels. It provides a high quality display output. It is capable of advanced de-interlacing, video enhancement, advanced 3D noise reduction, Y/C cross talk suppression and frame rate conversion. It also provides superior video output quality.
It integrates a complete triple 8-bit pipeline ADC with a clock-recovery and sync separation circuit to generate the sampling clock from HSYNC. An additional 24bit digital input is also provided for applications such as picture in picture (PIP). With the high quality video DACs, the video stream is displayed through its de-interlaced RGB/YPbPr outputs.
The I2C host interface enables OEMs to select from many different CPU’s in order to meet their system and technical requirements.
OEMs can easily design a very low cost solution, while minimizing their software development time by leveraging on TV5725’s level of integration and software support.
TrueView™ 5725 provides 3D motion adaptive de-interlacing with diagonal edge detection. It performs high quality line doubling and high-accuracy non-linear motion estimation. It performs pixel based motion detection using two-field buffers. The Video De-interlacing Processor automatically detects noise level and can respond to different noise thresholds. It can also automatically detect input modes such as still images, 3:2 / 2:2 two film and provide adaptive processing.
