tvb is not going to get a share of advertising here on astro. they are merely selling the rights to broadcast and astro already pays upfront. Since there is no more monetary incentive why would they care what else astro is broadcasting. It is not like Astro will cancel deal with TVB just because there is another deal with HKTV. I suppose TVB will not care what happened as long as its not competing with their ad revenue in Hong Kong.
