- Abstract
- Recently more people are watching video using mobile devices such as smart phones. Therefore CATV operators are planning N-Screen services to their subscribers. They have two ways to provide N-Screen services. One is an H/E based N-Screen approach that transforms contents into IP streams directly from H/E to subscriber's devices. The other one is a gateway based N-Screen approach that converts RF contents to IP streams in the gateway in order to deliver them to subscriber's devices. In this case, CATV operators can provide new N-Screen services with no change of their legacy broadcasting system. But long channel zapping time may be inevitable because of these legacy SI system. The aim of the present paper is to propose methods to reduce channel zapping in N-Screen services for cable operators.
