Hello, All I've written a ATSC scanner application for the Air2PC card that extracts the VCT sections from a channel that it finds a "Lock" on. Now this might be a more of a general DVB API question. 1) The card is supposed to support 32 Hardware PID filters. Now for instance my current programs just filters for a TVCT section How do I filter for multiply sections? I've attempted to fill in other pid sections, But doing this stops the card from reciveing ANY sections. It works fine as long as i only use one PID Mask pair, hence the coed that commented out. unsigned char filter[DMX_FILTER_SIZE]; unsigned char mask[DMX_FILTER_SIZE]; memset( filter, '\0', sizeof(filter)); memset( mask, '\0', sizeof(mask)); filter[0] = TVCG_TABLE_ID; // Look for the TVCG Table in Stream for OTA DTV //filter[1] = CVCG_TABLE_ID; // Look for the CVCG Table in Stream for Cable DTV mask[0] = 0xFF; // Mask //mask[1] = 0xFF; // Mask 2) How do I properly determine "Lock"? I understand that since the signal could have errors or bad data or Fade in / out ...etc. I understand that the values returned from the card are not normalized because the values might mean something differnt depending on the card and hardware. Whats the correct way to handle this? 3) Data Timeout what is a good value in the ATSC realm? Thanks, - Kevin Kevin D.
