Abstract: In a wireless data communication network, a mobile terminal is reconnected to a contents provider, when a connection established between the mobile terminal and the contents provider is interrupted or after a completion of the downloading of contents, by using return address information and contents address information including addresses of the contents provider and a web page including information relating to the downloaded contents, respectively. A WML (wireless markup language) script including the contents address information and the return address information is provided to the mobile terminal before initiating the downloading of the contents. In this way, the mobile terminal can easily be reconnected to the contents provider when the connection established between the mobile terminal and the contents provider is interrupted due to network congestion or the mobile terminal leaving the service coverage area.

Abstract: Disclosed herein are systems and methods for evaluating video quality. The systems include a video transmitter and a video receiver.
