Broadcast-based information dissemination systems on the Internet are becoming increasingly popular due to advances in the area of Web technology and information delivery. In this paper, we propose a concept and a way to construct a virtual TV channel, which is a user-deened (virtual) channel from existing push-based Internet channels. Our virtual TV channel is (1) to lter contents of multiple ...

In this paper we present optimization algorithms for image restoration based on the total variation (TV) minimization framework of Rudin, Osher, and Fatemi (ROF). Our approach formulates TV minimization as a second-order cone program which is then solved by interior-point algorithms that are efficient both in practice (using nested dissection and domain decomposition) and in theory (i.e., they ...

Television (TV) Commercial program contains important product information that displayed only in seconds. People who need that information has no insufficient time for noted it, even just for reading that information. This research work focus on automatically detect text and extract important information from a TV commercial to provide information in real time and for video indexing. We propose...

In the terrestrial digital TV systems broadcasting is employed, meaning that all TV programs are sent over all transmitters, also where there are no viewers. This is inefficient utilization of spectrum and transmitter equipment. Applying interactive multicasting over DV approach that would substantially reduce the spect to deliver a certain amount of TV programs be achieved by Dynamic single-fr...
