I'm referring to the video out of the receiver. What is the bandwidth of the video out (composite, Y/C, component if they have them)?


-3db at 2MHz, 3MHz, 4MHz, 5MHz etc.


The reason for the question is; everyone Direct TV I have seen on any channel it looks as I'm watching a Phony Smearitron from the 60's with the sharpness turned down (if such a thing would be possible). In other words a very rolled of picture that doesn't look as if has a bandwidth past 1.5MHz!

My DTivo (HDVR2) very sharply displays all the MPEG artifacts it decodes.


I use the SVideo output and it is noticeably better than the composite output.


However, there's no escaping the mosaic and jittery effects of the heavy mpeg compression that DBS employs.


I would estimate that the system is capable of remarkable resolution, should you ever be lucky enough to receive a signal that is not so stiffly compressed.


However, the need to have at least 400 home-shopping channels hawking crap jewelry, old-lady face cream and 'collectable' samurai swords, will obviously subrogate the available transponder bandwidth for entertainment programming.

I was looking forward to the 400 shopping channels.

I was hopeing that one of them would sell something that would put all of them off the air for good!


Seriously; I was looking for a test by someone that could run a sweep or multiburst through the system with the -3db points at the output.

I don't know of any means of getting a high quality signal into any of the DBS receivers in order to be able take a meaningful measurement of the response. DirectTV sure ain't gonna broadcast one. :)


I'd estimate it as about as good as a run of the mill DVD player.

I bet it's not!

I would go further and say I bet it is less than 2 or maybe 3 MHz on most of the channels I have seen on more than one monitor!
