Force satellite scan from module

Hi,

I'd like to launch satellite scan from a module. Is there a way to do that using the DvbDream API?

What I'm trying to do is to keep DD up to date with the provider settings. Ideally, I'd need a silent operation that update DD (including channel deletes) without any user interventions.

No one knows are is it that it just can't be done with the current API?

Rel, is there anyway to add the API that would allow sat scan from modules?

what do you mean under "silent operation"?
you can not do channel watching and satellite scan "in the background".
you need a second tuner to do that.

so far your description of what you want is rather vague.

I have absolutely no idea what you meant by that?

Thank you for the reply.

What I want to do is to stay up to date with the content of the satellite transponders. The problem is that the provider can add, delete or move channels on the satellite. What can happen in the case of a channel move is that the channel will stop working in dvbdream and a satellite re-scan is required to get the channel on it's new transponder. One that channel is found on the new transponder, it can be watched again.

Of course, I understand that it's not possible to watch any channels while scanning satellite. What I meant by "silent operation" is an operation which would not involves any user actions. This is a maintenance process. However, I wonder how the STB stay up-to-date with the satellite configuration. Maybe dvbdream could do the same? It might also be me that missed something.

Cause STB never goes off.
When you switch it off with remote, it does not switch off the tuner.
Instead it re-tunes to the transponder which has extended EPG.
The same transponder also has streams with latest firmware for your STB model (and firmware has information "what satellite to look for particular network ID").
And receiver stays tuned to that transponder all the time, until you switch receiver on (with remote) and start switching channels.
This is how "silent" scanning is done (it's done NOT in the background, but when you switch your STB in this mode).
You can do the same job just doing a plain re-scan.

Ok, thanks for the explanations.

What I want to do is to trigger a scheduled scan from a module. I never turn off my dvbdream and I don't permanently watch it either, so I could launch scan on a scheduled basis.

I get back to my original question: Is their a way for a scan, without any user actions, to be triggered from the API?

Anyone could help? Rel, please give me some answers...

Does anyone know Rel? He might be stuck in an ice cube or something. Why is there no answers from him? Rel if you just don't see the point for such a feature tell me. If you don't understand my question, please tell me.

This is a module API help / support section for programmers. There is not much support at all. Is this product dying? I certainly hope not.

Sorry for being too arch, but that question has been left in the air for too long.

so far, neither device driver/interfaces is able to modify ANY dvb dream's files. In fact, driver/interface has no clue about channels. How on earth it can do a scan, if it does not know what scan is?
And I prefer to leave it this way.

Thus, the answer t you question:
No, it does not make sense.

genpix, I don't think you understood my question... or I don't understand how the SDK/module works.

I want to trigger a scan in the application, using a message just like any other SDK functions. It would be just like going in the dvbdream's menu and select satellite scan, but instead of being started manually by the user, it would be started by a module though an SDK function (a message). If you look at the SDK, you'll see that the concept of channel information is clearly know by modules and I would even say is the base of the SDK.

I don't know what's impossible with that approach. If you do, please enlighten me!

hi,

busy times , can hadly reply, sorry.. lol

there is no way to start a scan using moduleAPI yet

An API command could be added in future versions but there are lots of things to do before that.

Thanks for the reply rel.

I'll look for alternative way to do it. I'm thinking if using the Win32 API to select the right menu options and launch the scan.
