My local cable co gives me a channel called THD, I believe it means Team HD which is an InDemand channel. InDemand is the same company that provides the NHL Center Ice package to cable companies.
According to my rep, anytime there is a broadcast NHL game in in HD it will default to the THD channel. Now I know there are several games per day in HD so I am thinking it will be random as to which game or team is shown. I didn't have this channel last year so I don't know exactly how it will work.
I have INHD and last year the HD versus game would default to the INHD channel. As the end of the season came, basketball games in HD defaulted to that channel instead of hockey.
