Hello, I am trying the examples that came with DM642 evaluation board, and the video drivers are working fine if i want to display a D1 frame into a monitor. I am trying to program the saa7105 video encoder to perform scaling from CIF to D1. Did anybody accomplish this task? Can anybody tell me which registers do we have to change in order to perform this? I do know that we have to change XINC and YINC, but I am having problems knowing to which values. The saa7105 datasheet (for me, a guy with little experience about analog TV) has little information about some basics of analog TV, and when it comes to program the horizontal/vertical scaler i have a question regarding to the following variable: InPpl: the length of the entire input line in pixel clocks. If anybody can point me out to some resources about video encoders, analog TV basics, i'll appreciate. Thanks in advance, A.Silva
