notifyPrivateDescriptor
boolean notifyPrivateDescriptor(byte[] descriptor)
This is a call back method to notify a private descriptor in the cable_emergency_alert message defined in [SCTE 18]. If the alert_priority=15 but no audio specified by [SCTE 18] is available, the OCAP implementation shall call this method. The OCAP-J application can get a location of an alternative audio specified in the private descriptor and play it according to [SCTE 18]. If the OCAP-J application doesn't support the private descriptor, the EAShandler.notifyPrivateDescriptor() method shall return false and the OCAP implementation can play detailed channel or proprietary audio. This method shall return immediately. The audio shall be played in a unique thread not to prevent an alert text representation.
- Parameters:
descriptor- an array of bytes of a private descriptor in the cable_emergency_alert message defined in [SCTE 18].- Returns:
- true if the OCAP-J application can sound an audio of the location of the specified descriptor.
stopAudio
void stopAudio()
- This is a call back method to notify that the alert duration has
finished. The OCAP-J application stops an audio specified by a
private descriptor. The OCAP-J application shall not unregister
the EASHandler until terminating an audio by this method.
