Broadcast Flags
 

I subscribe to both Comcasts Broadband Internet and Cable TV service.
Since I live in an apartment, I only have a single line coming in.
Comcast installed a splitter and a line going to my TV and a second line
off the splitter going to my cable modem. Initially I had problems with
my Broadband Internet connection. The Comcast serviceman said the
problem was the filters installed to block premium TV reception. I only
subscribe to the Basic Cable TV service. The filters were removed by
Comcast to fix my Broadband Internet service.

What are and what is the purpose of broadcast flags. My firewall logs
almost 100 blocked broadcast flags from Comcast every day. Should I
allow my firewall to accept the broadcast flags from Comcast. I have a
built in QAM HD tuner in my Mits TV. There have been instances when
while watching TV the reception of a station has gone off the air and my
TV has shut off by itself. I have to use the "System Reset" to turn my
TV back on. All my channels in memory have been erased and I have to
rescan to find all the lost channels. Do the blocked broadcast flags
have anything to do with that.

Far I now broadcast flags are part of HDTV signal that will not allow
copyright material to be copied, the digital equivalent to
Macrovision.
