FTTVE100电视编码控制器IP开发

To Develop FTTVE100 TV Encoder IP

多媒体手持设备带有TV-out视频输出功能堪称一大亮点。TV-Out的使用简单便捷,只要把传输线一端接上手持设备的视频接口,再将另一端插入电视AV孔,与PAL或NTSC电视直接进行联机。以往要实现这项功能依靠的是外接一颗电视编码芯片,随着SoC设计的概念普及,越来越多的SoC芯片会将这个功能整合进来,所以提供一个好的电视编码控制器IP给芯片公司来设计SoC将成为主流。本文主要说明智原科技如何根据电视时序的要求设计电视编码控制器IP,以及如何在FPGA开发板上跟视频DAC测试样片做验证。

To have a TV-out feature for a portable device is a spotlight in multimedia application. TV-Out is easy for people to use, user just need to plug one side of transmission line to the portable device, and the other side to PAL or NTSC TV AV connector, then we may connect the portable device to the TV. In the past, people implement this feature by an external TV encoder IC. Along with the SoC design concept popular, more and more SoC chips integrate this feature inside the chip. So provide a TV encoder IP with good quality for chip vender to design SoC will become a mainstream. We will illustrate how Faraday Technology based on the TV timing requirement to develop the TV encoder IP, and how to verify the IP on FPGA with the Video DAC testchip.
