Toronto • Hockey is so crucial to television revenue streams that Canada’s largest media companies are battling publicly over access to camera angles during games.

The fight revolves around an online feature that Rogers Communications offers customers called GamePlus, which enables users to watch and replay game footage from multiple angles, including a camera mounted on a referee’s helmet. BCE Inc., known as Bell, was first to complain to regulators that its subscribers should have access to those same online options.

It’s not just camera angles that are at stake. In question is whether Rogers’s $4.6 billion (U.S.) deal to distribute National Hockey League games in Canada will pay off, as well as what regulators deem to be TV content in the Internet age. The 12-year hockey contract, signed last year, was a bet that Rogers could win new subscribers by offering video on tablets and smartphones. While companies are required to provide universal access to content produced for TV, the same rules don’t currently apply to Internet-only media.
