Summary of DVB-S table oddities in NA

Reported by: yeasah@… Owned by: danielk
Priority: minor Milestone: 0.20
Component: dvb Version: head
Severity: medium Keywords:
Cc: Ticket locked: no


Here are scans of PAT/NIT/SDT/EIT using dvbsnoop of providers listed on LyngSat? for North America. Various issues prevent tuning for some providers, as summarized below. This ticket is meant both as a description of what might be broken in actual use, as well as a description of the sort of real-world oddities that the DVB code should be able to handle gracefully.

Actual dvbsnoop logs are attached as a fairly large (~400K) bz2 compressed tarball.


Dish Network/Sky Angel  61.5W (also 105W, 110W, 119W, 121W, 129W, 148W)

        SDT marked as active is not for correct ts
        NITs correctly marked as active/other
        SDT and NIT run loops for all transport streams on all sats
        Average SDT interval: 24 seconds
        Average NIT interval: 2 seconds

        SDT and NIT run loops for all transport streams on all sats
