satcruiser DSR101 +

Does anyone know the difference between Network Search and Channel search in the satcruiser dsr101 + under the TP settings page

is the search feature on the sat page is a blind scan or known TPs scan ?

there is also a multi sat search. the manual is not clear

This same question came up with respect to the Fortec receivers a while back. Never did completely figure it out, however the Fortec manual says something to the effect that in a regular transponder search, if a freq/SR combination is scanned, and the channel info has changed, that the channel info is NOT updated, but in a Network search, this info IS updated.
At that time, I tried to experiment on some channels that I knew had changed info, but I couldn't come to any conclusion with respect to what the real difference was.
I think there is information about the channels in the NIT, SDT and EIT, etc sections of a stream, and the receiver may or may not use this info. For example, the name of the channel is one of these items. Sometimes you do a re-scan, and a new channel has replaced an old channel, and the name remains that of the old channel. Supposedly a Network scan would update to the new name, but I didn't find that to be the case with the Ultra. Maybe it actually works with the dsr101???

I just found an old manual on the net. and i think network search is the Blind Search. has to be tested though

It's definately NOT the blind search on the Fortec receivers. They call their blind search Power search, and the Network search only searches transponders that are already saved, and you have to choose a single transponder, ie it doesn't seach for transponders at all. May be different on other receivers though.
On the Fortec's, I can't see any difference between a Network search and a Transponder search. I've done both Network and Transponder search in situations where the channel info has changed, but I can't see any way that they differ.

I never figured that one out either but I do know the DSR 101+ is not a Blind Search receiver.

I think network search would also find transponders that belong to network like Globecast. So if a network transponder has changed, network search would find the new transponder.
Example: recently globecast (IA5) changed TP 11929 channels to 12083. If you perform a network search, it would update 11929 to 12083 and find moved channels.

At least on the Fortec, the Network search requires that you scan on a transponder, so if you tried to scan the 11929 TP in your example, nothing would be found. However I don't know what would happen if the 12083 TP was scanned.... ie perhaps it would replace the previously saved channels from the 11929 TP, rather than creating NEW channels, which is what a TP scan does ??? Unfortunately, I don't have the 11929 TP saved on my receiver, or I'd give that a try. I'll have to watch for another TP change on IA5 and see if that happens.

This does introduce another question though, and that is, just where is this "network info" stored on the receiver. Ie I was thinking about loading in an old channel list that I saved using the PC channel editor, which might contain the 11929 mux you mention, however the saved channel list doesn't contain any info other than the Freq/Sr channel names, channel numbers, and the PIDs, so I don't know how a network search would identify the channels, other than by the name, which isn't a very reliable method.

Anyway, I've experimented with a few cases where network info changed on a channel, but wasn't able to see any difference between network and TP scans, but next time I hear about a change on IA5 I'll try again. However, I guess that means I should scan in all the IA5 muxes, since I haven't done that, as I don't watch that sat much.
