On a ff_card, the Transport Stream that comes from the CAM (with some packets decrypted as you say) or from the frontend (if the CAM/CI aren't plugged), is sent to the AV711x which decode & output the video & audio; simultaneously the decoded video is sent to the SAA7146, for display on a VGA or V4L applications. Optionally, some TS packets are sent to the SAA7146 (passing its by the DPRAM and DEBI interface), for recording / streaming / timeshift / etc applications.
