Currently, we can't see any structs and IOCTL commands related to DVBS blind scan in Linux-dvb framework. So we want to confirm if Linux-dvb framework have inherent flow of DVBS blind scan or not. If the answer is yes, could you tell us how to work in Linux-dvb. If the answer is no, do you have any suggestions or design scenario for DVBS blind scan? Sorry to bother you and thanks for your helps. BRs, YP
