Development of Prototype Receiver for Program Index

Abstract

The Program Index is a metadata of TV program for new broadcasting services such as multi-scenario program, hierachical program and so on. We have developed an experimental end-to-end system of the Program Index. In this paper, we describe the receiver part of the system, which can browse the tree structure of program segments and play the segments selectively. We also describe POT (PTS Offset Table) code, which improves efficient time accuracy of the Program Index.
