摘要
设计了基于DSP的SDTV/HDTV电视信号格式转换卡。运用双线性插值的方法,在DSP上实现对图像实时的放大处理,算法已在ADSP-TS201S开发板上得到验证,效果良好。设计难点在于,数字电视信号的时钟频率很高,要处理的信号量极大,因此采用多DSP并行处理。
The circuit board design of SDTV/HDTV format conversion is proposed.Using the method of bilinear interpolation, which has been testified well on ADSP-TS201S EZ-KIT LITE evaluation board,the realization of real-time image enlargement processing based on DSP is accessible.The difficulty of the design is that the clock signal frequency of digital TV is so high that a large amount of information needs to be dealt with in a short period of time,so the method of muhi-DSPs parallel processing is employed.
