BDA MPEG-2 Transport Information Filter

Digital TV transmissions multiplex many programs and their related elementary streams (e.g. audio, video, IP data) in a single transport stream. So that a receiver can properly acquire all the elementary streams related to a specific program and so that a receiver can tell what programs are contained in the stream, the transport stream will also contain many sets of tables that act as a catalog of information contained in the transport stream. Under direction of the BDA Network Provider, the MPEG-2 Demultiplexer delivers these tables to the Transport Information Filter. The Transport Information Filter then parses these tables and provides the information to the Network Provider so that it can control the other receiver filters in the graph.

This filter also provides COM interfaces that enable a Guide Store loader application to retrieve in-band EPG information.

The BDA MPEG-2 Transport Information Filter appears in GraphEdit under the "BDA Transport Information Renderers" category.
