"That may allow people to have larger TVs over time, if that technology ever proliferates," said Zitter.

A big part of life at HBO is the encoding; turning the recorded content into something that can be distributed to a TV or a tablet. In the last year and a half, HBO has changed the equipment used to do this twice, according to Zitter.

"We have just improved our encoding to where we have been able to lower the date rates for HD from 3.4M bps and do the same quality to about 2.9M bps. That's good for everyone in the food chain, because streaming costs are lower and you get a higher quality without using as much data," said Zitter.

Zitter expects bandwidth requirements will be halved with the introduction of HEVC (High Efficiency Video Coding), a new encoding technology due in about two years.

Even though he is a veteran in the TV business, Zitter still gets excited about the development of new technologies, like TV on the go and the ability to make programming more personal, and the opportunities they bring.
