SIDatabase

Package com.sun.dtv.service Description

This package provides an interface for accessing the Low Level SI database.

Overview

This package contains the Service Information (SI) API to access the low level SI database which contains the SI tables. The class in this package provides a way to obtain a reference to the actual low level SI Database, which is dependent on the transport system. An actual SIDatabase implementation must be derived from the SIDatabase as defined in this package and provide access methods and class definitions for the individual SI tables.

Design

Description

This package describes a common abstraction to provide access to the low level service information (SI) of the broadcasting system.

To be fully flexible the SIDatabase provides a common base class, from which the actual SIDatabase implementation class is derived. This mechanism permits to use different SI database formats as provided in the actual broadcasting system.

For this purpose it defines a SIDatabase class, which is a to be used as a base class for the actual SI database implementations. From this base class an actual SI database implementation A SI database provides means to asynchronously query or monitor SI tables, which are transmitted in the MPEG-2 transport stream. The MPEG-2 specification defines the common format of the SI tables and mandates a minimum set of tables. Actual transmission standards, like DVB, ARIB or ATSC define additional tables, which correspond to the service information used in this network. It depends on the broadcasting standard and the geographic location, which kind of tables are supported.
