Description cjunwang 2014-05-23 01:58:06 UTC 
ATSC EIT/ETT has unfixed pids.  these pids can be parsed from Master Guide Table, by table type(EIT0-127:0x0100-0x017F, ETT0-127:0x0200-0x027F).

Current mpegtsbase do not filter unfixed pids' EIT/ETT.

The proposed solution:
1) Add two signal "add-psi-pids" and "remove-psi-pids" to mpegtsbase 
2) tv sevice can emit the two siganls and let mpegtsbase dynamically add/remove pids filtering.

There is another possible solution
https://bugzilla.gnome.org/show_bug.cgi?id=730435

In that solution, besides MGT/EIT/ETT support, mpegtsbase can also automatically parse MGT and set filtering for EIT/ETT. 

The reason I want to propose this is, 
1) It's possible to have many EIT/ETT, let tv service set which be filtered should be more flexible.
2) these two signals can be used for not only EIT/ETT, but also any unfixed pids.
3) tv service need get not only sections, but also the relationship between EIT/ETT pid and EIT/ETT table_type.

Any assistance or comments are welcomed...
