Stream Errors with 100% DVB-T Signal

[AleXNight]

Hi!

When I record Digital TV with DVBViewer using a DVB-T USB Tuner by AVerMedia (model A867) I often get Stream Errors.

The resulting TS file is corrupted like what you see in this picture:

 

 

Is there a way to avoid these Stream Errors?

I've got 100% DVB-T Signal for the channels I want to record from.

 

I've got this setup: Aerial Antenna > Antenna RF Cable > USB DVB-T > USB Extension Cable > PC.

May the extension cable degrade the signal from the USB Tuner to PC?

 

I know that when a Digital Signal is broadcasted, the broadcaster airs also a part that is dedicated to the correction of reception errors. This thing is called FEC (Forward Error Correction).

Using a DVB-T PVR Decoder the Error Correction is done by itself. In my setup (USB DVB-T + DVBViewer) who does it?

Is DVBViewer capable to do the FEC?

 

Thanks in advance!

Good bye!

The signal strength often can be very misleading. If it`s always showing 100% it's pretty useless.

no

 

Is DVBViewer capable to do the FEC?

no, the fec is used by the digtal demodulator in the dvb(t) receiver.

Is there a way to get useful signal informations?

I noticed that when I use a T-Splitter, Stream Errors became less frequent.

May a too strong signal saturate the USB Tuner?

I use a Splitter like this:

 

My setup now is the following: Antenna > RF Antenna Cable > T-Splitter > USB DVB-T > Extension Cable > PC.

 

Anyway, I haven't got 100% Signal on all channels.

Do you know a DVB-T Tuner that does a nice Error Correction?

Is there a way to verify if it's done well by mine?

 

Thanks in advance!

if your signal is too high you could try an attenuater .....your RF signal should be in the mV range if I remember correctly ....or you could experiment with variable resitor.
