Freezes, High CPU usage, Blue screens!
September 9th, 2007

Q. What parameters can cause freezes and high CPU usage during watching an encrypted channel with emulators?
A.

DW’s
Do not use multiple active EMU’s at once. It’s very important.
This is the main job of emulators:
Receiving ECM’s from the Host (DVB application) -> doing processing on those packets -> sending final result (DW’s or decrypted words) back to the host.
Now suppose you have running 2 EMU’s at once. One of them sends a correct DW and another one sends an incorrect DW. Result is freeze. Host program will process all of them. It is not able to identify which one is correct and which one is incorrect.

Codecs
Do not mess your system with All in one codec packages.
If you want to screw your current Windows installation (especially if it Vista), go a head! Now enjoy freezes, poor video output and post, hey you bastard! your plugin does not work!
For example after installing the famous “vista codec package” on your Windows Vista (which is not recommended for dvb-s applications), you have only one option : reinstalling your Windows!

Poor signal level.
Duh!

Blue screens! http://en.wikipedia.org/wiki/Blue_Screen_of_Death
Most of the times blue screens mean hardware conflicts.
If you are using AMD based computers, and you have at least 2 blue screens per day, do not forget to update the BIOS and drivers of your system. (I had the same problem)
Try latest driver of your dvb-s card instead of original driver which was shipped with your card.
Also try non BDA drivers of your DVB-S card.
Sometimes changing the PCI slut of your internal card will help.

Dual core CPU’s
Results of the Incorrect synchronizations during multithreading are freezes and deadlocks.
Some of the dvb-s applications are NOT compatible with dual core CPU’s.
Try to change the CPU affinity on your dvb-s application (by using windows task manager) or some of the dvb-s applications have this option internally.

Running unnecessary features
Satellite time was introduced in vPlug for TPS channels to eliminate the answering of this question:
Why TPS channels are working for 5 minutes , then I have black screen and so on.
TPS uses this cycle:
[Viaccess-1] - TPSCrypt4 - [Viaccess-1] - TPSCrypt4 and so on.
[Viaccess-1] does not need any kinds of time synchronization.
So if your system’s time is not synchronized correctly , you will have color - black- color …
By enabling SatTime in vPlug.ini, you don’t need to be worry about these details.
And if your system’s time is synchronized correctly, just turn it off and enjoy fast channel changing of TPS channels and low system’s resources consumption.
[this feature is on by default and will be …]

Also EMM handling needs a lot of system’s resources [Memory, CPU]. If your keys are correct, turn off EMM handling and AU in vPlug. (edit vPlug.ini or v_emm.ini)

CSA and FFdeCSA http://csa.irde.to/
CSA or common scrambling algorithm, is the final process of decrypting an encrypted signal and normally it’s done by the host (your dvb-s application) .
It has been implemented in 2 ways: CSA.DLL and FFDeCSA.DLL. (most of the DVB applications have included these algo’s internally, so you won’t notice the existence of them.)
CSA.DLL can process one packet at a time and FFDeCSA.DLL is designed for processing of multiple packets at once. So by using FFDeCSA, CPU usage will be reduced dramatically as you can see it some the dvb applications. It’s very important for HD channels (reducing CPU usage as much as possible). You will have a lot of freezes during watching of HD encrypted channels Without FFDeCSA, and this is not the bug in processing of ECM’s by EMU’s.
You have 2 choices for HD channels. Upgrade the hardware’s of your computer and continue using of your dvb application which is using CSA.DLL or switch to an application with FFDeCSA support.
For example ALT-DVB is using FFDeCSA(.dll) (one of the 1st in Windows) and ProgDVB or MT are using CSA(.dll) internally (till now).

If you have a P-III, it’s better to buy a hardware based dvb-s card. For example a Nexus-s has an onboard CSA chip and also MPEG2 decoder. You will have max 10% CPU usage with that on encrypted channels. “But” these cards can not pass the full TS to dvb applications by design and it will cause a lot of headaches for programmers. So most of the new born dvb applications do not support them.

News: http://vplug.wordpress.com/

"10.09.2007
V 1.8.5
- Added New NA N2 MECM$40 handling.
- Added SLO-TV VIA-1 AU.
- Added signature check for decrypted Cmd $BA.
(if they change the 3DST key, you will notice that)"

Thnks vahid!

In unele cazuri e necesar sa dezactivam functia autoupdate pentru anumiti provideri, fie pentru a reduce consumul de microprocesor, fie pentru a evita scrierea unor chei false peste cele introduse manual in cazul in care AU nu merge corect.
Pentru aceasta putem edita fisierul v_emm.ini :
In loc de AutoStartOnChannelChange=1 punem AutoStartOnChannelChange=0 pentru providerul dorit, sau editam direct in Monitor:



Lista cu provideri:

007C00 = Tps
0101, 0901, 0001, 0801 = BEV, Dish
009400 = Srg
7101 = Polsat
4901 = TvCabo
4101, 4102 = D+
0501 = Premiere
0030 = RAI
0604 = ShowTime
2111, 2011 = D*g*
00B000 = SLO TV

SALUT am si eu o antrebare daca ma puteti lamuri, se tot zicea ca:vPlug1.8.4 face AU. la jiji , dar la mine nu face de ce? ss2 echosmart 771. SALUT.

Pentru ca nu mai merge

[SLAman]

vPlug nu mai face autoupdate nici pe D+.

A aparut vPlug1.8.6
http://rapidshare.com/files/55772944/vPlug1.8.6.rar

"15.09.2007
V 1.8.6
- Fixed D+ AU.
- Added keys files monitor.
(vPlug will check the changes of keys files which are done by external tools every 1 minute.)"

"Now you can use external programs for updating vPlug’s files without restarting your dvb-s application."

Poate fi ca vplugu nou consuma mai multa memorie de cit 1.86? Dupa un reboot zice ca Free Mem 61%, 1.86 avea cam 73%. Am 1 GB Ram, dece atunci Free Mem 61%? Nu cred ca ia decodarea atit de mult, mai ales ca folosesc un dvb-s 1.3 la care nu-i trebue softcsa fiindca are un ECD in DSP.

Ba face. Testat chiar acum. Versiunea 1.8.7.1 a facut update in 24 de secunde.

My mistake Am avut doar 1.8.7 iar acesta a fost motivul:Fixed ECM parsing of Cryptoworks. Some other minor fixes pt.1.8.7.1
