Class PODExtendedChannel
java.lang.Object
org.davic.mpeg.TransportStream
org.ocap.mpeg.PODExtendedChannel
public abstract class PODExtendedChannel
- extends TransportStream
This class represents an extended channel that provides access to private section data flows. The extended channel is defined in the Host-POD Interface Standard (SCTE 28). When this class is specified as the stream parameter of the org.davic.mpeg.sections.SectionFilterGroup.attach(TransportStream, ResourceClient, Object) method, the SectionFilterGroup is connected to the extended channel, i.e., the filters in the SectionFilterGroup filter the private section data via OOB. The extended channel flow to be opened is specified by PID, when the org.davic.mpeg.sections.SectionFilter.startFiltering() method is called.
The methods defined in the super class (org.davic.mpeg.TransportStream) shall behave as follows:
- The getTransportStreamId() method returns -1.
- The retrieveService(int serviceId) method returns null.
- The retrieveServices() method returns null.
