The first perspective, watching TV, is called "ego-centric".You are using "I" as the central reference point, and all action is described in relation to that. (If you think about it, it's not necessarily that you watch TV. It maybe that a stream of information gets projected at a memory store, triggering reactions and associations.) To think that you are the one watching gives too much credit to the role of being a sink.
The second perspective is called "mixing mind with space". It is what we sometimes use in meditation. To be aware of the space around you helps avoid falling asleep.
The third perspective, people watching you, is called "imaginary importance". You imagine that people's eyes and thoughts must be directed at you, as if you were so important as to occupy the central place in their minds. But the people looking at you in your imagination are not real people, they are your projections, figments of your imagination. Real people are occupied with their own interests. Your importance to them is imaginary and is a sign of vulnerable and hungry ego. Cultivating this perspective is twice as bad as the regular egocentric perspective, so you should avoid it like a plague.
The right way to see things, according to Buddhism, is from thousand-miles-high point of view, the so-called "divine eye". Divine eye is the impersonal perspective, completely neutral, not taking any sides.
The ultimate way to see things is "Buddha's eye". This means, to see things from all perspectives at once.
