Tvheadend

You mean the graphic identity/channel identified/DOG/Digitally Originated Graphic? Very difficult, if not impossible. It's part of the image - it'd be like airbrushing your aunt out of a photo.

I found an application a few years ago that could blur the image, but it's massively slow as it needs to uncompress the whole file into individual frames, process each one and then recompress. And I don't remember it being very successful either. And even if it were, it can't create part of the image that's missing, so if you have trailers for the next programme across the bottom of the screen (as do many prime-time US TV shows) there's simply no way of resconstructing the part of the image that's been "obscured".

Hi

Thanks Prorf Yaffle for the reply

i understood your point , but what i want , when the data and the identity of the receiver shows , i want the screen to be blank or skipped or what ever just to hide the Data showed.

Is it possible?

Best Regards

Sorry, I'm still not completely following. If you want to cut out the broadcast between the "receiver identity" - so skip over adverts/commercials - then tvheadend can't do that automatically. The one exception may be for the following (from the help text):

Skip commercials

If checked, commercials will be dropped from the recordings. At the moment, commercial detection only works for the swedish channel TV4.

However, there is a version of comskip for Linux that you could look at - I don't know what you're running tvheadend on or how long comskip would take, but you could make use it as part of a post-processing command. This won't skip commercials in live TV (obviously) or when playing back via e.g. the XBMC PVR addon - only when using a client like XBMC or mplayer to open the native recorded file (.ts or .mkv).

If I've still misunderstood you then my apologies, happy to try again!
