Description
Interface Summary | |
SectionFilterListener | The SectionFilterListener interface is implemented by classes which wish to be informed about events relating to section filters. |
Class Summary | |
EndOfFilteringEvent | This class is used to report the end of a filtering operation started by RingSectionFilter or TableSectionFilter. |
FilterResourcesAvailableEvent | This event signals that enough section filter resources for the corresponding section filter group were available at the time this event was generated. |
ForcedDisconnectedEvent | This class is used to report when a TransportStream which was available becomes no longer available or if the section filter resources are removed from a connected SectionFilterGroup. |
IncompleteFilteringEvent | This class is used to report the end of a filtering operation started by TableSectionFilter. |
RingSectionFilter | This class defines a section filter intended to be used to capture a continuous stream of MPEG-2 sections without needing to stop and re-arm a filter. |
Section | This class describes a single section as filtered from an MPEG transport stream. |
SectionAvailableEvent | This class is used to report a complete section being filtered. |
SectionFilter | This class is the base class for a set of classes describing section filters with different characteristics of life cycle and buffering. |
SectionFilterEvent | This class is the base class for Events in the section filter API. |
SectionFilterGroup | This class represents a group of MPEG-2 section filters to be activated and de-activated as an atomic operation. |
SimpleSectionFilter | This class defines a simple section filter intended to be used to capture a single section once only. |
TableSectionFilter | This class defines a section filter operation optimized to capture entire tables with minimum intervention required from the application. |
TimeOutEvent | This event is generated if section filter operations time out within the period specified by the setTimeOut() method. |
VersionChangeDetectedEvent | This class is used by TableSectionFilter to report that a section has been encountered which has a different version_number from earlier sections. |
Exception Summary | |
ConnectionLostException | Signals that a SectionFilterGroup has lost its connection or resources and hence is unable to satisfy a call to a startFiltering method. |
FilteringInterruptedException | Signals that a filtering operation was interrupted before any data had been filtered. |
FilterResourceException | Signals that inadequate resources are available to support the requested operation when a SectionFilterGroup is in the connected or disconnected states. |
IllegalFilterDefinitionException | Signals that a requested filter definition is not valid. |
InvalidSourceException | Signals that the section source specified is not valid for some reason. |
NoDataAvailableException | Signals that no data is available from a Section object. |
SectionFilterException | This is the base class for exceptions in the section filter API. |
Provides access to MPEG-2 section filtering.
The following errata agreed in DVB have been implemented with respect to the original DAVIC work.
Like other startFiltering methods, org.davic.mpeg.sections.SectionFilter.startFiltering
(appData, pid, tableId)
shall throw an IllegalFilterDefinitionException where :
the java integer parameters are either negative or outside the range allowed by the
MPEG specification.
Remove the following text from the methods of org.davic.mpeg.sections.Section "(everything after the length field, not including a CRC check)".
A NotAuthorizedException is added to the list of the exceptions which can be thrown by this method.
This method is considered to have the following text appended to its description: "Returns true when the Section object contains valid data."
In the description of this class there are 12 instances of a cross reference to H7. In each case this should be a reference to E.8.1.
Is considered to have the following text appended to its description:
All sections in a ring section filter are initialised to empty when the ring section filter is first created. Clearing them to empty any time after this is the responsibility of the application. Starting a ring section filter shall not clear any of the sections to empty.
Section is considered to have the method clone() with the following behaviour.
A cloned Section object is a new and separate object. It is unaffected by changes in the state of the original Section object or restarting of the SectionFilter the source Section object originated from. The clone method must be implemented without declaring exceptions.
In these methods,the description of when the FilterResourceException shall be thrown is considered to have the following text appended to its description: When a SectionFilterGroup is detached, either by the client or through resource withdrawal, started SectionFilters shall remain started. Hence if the SectionFilterGroup is re-attached, those filters shall re-activate.
In MHP 1.0.1, this was applied to SectionFilter.start which has been corrected (DVB issue #2208).
This method is considered to have the following text appended to its description:
Note that this is applied whether the parent section filter group is connected to a TS or not.
The constructors for SectionFilterGroup are considered to have the following text appended to their description:
Throws illegal argument exception if numberOfFilters <1.
The methods with a parameter called sectionSize shall be considered to have the following text appended to their description.
Throws IllegalArgumentException if sectionSize <1.
These methods shall be considered to have the following text appended to their description.
Throws IllegalArgumentException if ringSize <1.
This is considered to have the following text appended to its description:
The scope of the resourcePriority shall be a single application only.
