My HDR receives a signal from Freeview (F) and Saorview (S).
I have noticed recently on one HDR that when it is switched on, not having being used that day (i.e. no recordings, no browsing of channels or media files), it has a full 6 Day EPG for both areas (F+S). Note on webif the EPG is only one region/area (S).
My preference would be to see the full EPG for both regions simultaneously! However as soon as a channel is changed the EPG from one region disappears.
I have noticed that it only happens when the box is not used for the whole day. AND strangely it only happens on one HDR, on the other HDR it has not happened yet.
I tried a few things and then realised that it only happened on the HDR that I had poweron installed. I had set poweron to CBEEBIES and realised that on the evenings that this happened I powered on the HDR when CBEEBIES had stopped transmitting for the evening.
To test this I installed Poweron on the other box, set it to poweron to CBEEBIES. I left it to power off on a Saorview Channel with only the Saorview EPG on the HDR. That night when I came back I switched on both HDRS and both had almost 6 days EPG displayed for both regions.
What was even more surprising was that when I went in to guide>find and searched by keyword I was able to search both EPG regions. Even pressing the recording options on both regions offered me to record the program only or the series.
This doesn’t happen to the EPGS during the day. I wonder is the difference that during the day the signal is carrying the EPG in the broadcast stream where as at night when the box is ‘powered on’ to CBEEBIES there is no EPG broadcast so the EPG on the Humax is not altered from startup.
I realise this situation is different to multi-region but I also wonder if this is reproducible on a box receiving two Freeview regions ?
I suspect the Humax software uses an in-memory copy of the data and just dumps it periodically so that it can reload it at startup in order that the guide works straight away.
It would seem that the EPG is sorted and stored ready for startup but this time the Hummy did not know which data/region to display so it displayed all the stored data.
One question from this is what is the different when the box powers up onto a channel like CBEEBIES in the evening that has stopped transmitting?
I waited for over 15 minutes and can confirm that the EPG was not updated and the Data from both regions was still present. I then, without changing a channel, played a stored media file and the Saorview EPG disappeared on the Hummy. Both EPGs still appeared on webif, but it normally takes webif 15 minutes or so to change to the active region. About 15 minutes after the media file was played webif is now only showing the Freeview EPG also suggesting an EPG update may have occurred.
Another question this raises does playing a media file also trigger EPG update similar to changing channel?
So I'm convinced all the data is there, the Humax just seems capable of displaying the on-screen EPG from only one transmitter at a time.
I would agree. Yes all the data is there. But the humax is capable of displaying the on-screen EPG from both transmitters, albeit only under certain conditions!!! It even allows EPG searches from the two regions.
I accept that conflicts over AR flags and current/now next information mean that the box should only ‘tune’ to one transmitter at a time but what about having both EPGs simultaneously?
