In order to help with the discussions, I prepared a set of slides that explains how the DVB pipelines are and what are the issues with MC. They're at: http://linuxtv.org/downloads/presentations/media_summit_2015_US/dtv_media_controller_discussion_v1.pdf I added there the links for the related messages that were sent to the mailing list. Please notice that the example at slide 8 is fictional, as getting those hardware diagrams would generally require to sign an NDA. So, the example were created from a slide that I found at the Internet, under: http://www.eetasia.com/ARTICLES/2005AUG/4/2005AUG22_EMS_NP.gif where I merged the missing entities demod and demux, and guessed that the output could be sent through GPU and ALSA pipelines, and that cross-bars would allow different pipeline arrangements. So, while it is a fictional diagram, it is actually pretty close to what would happen on a real hardware for a TV set or a Set Top Box.
