NOTE: This is only supported in dual tuner configuration since the secondary tuner needs to perform continuous scanning for frequencies broadcasting given Programme Type while the primary tuner is used for normal tuner activities. Client should first check the tuner capabilities. Will return KErrNotSupported in callback method if this feature is not supported.

Asynchronous request to find all Programme Service names (PS) sending Traffic Announcement (TA). User must be ready to receive callback method GetPSByTAComplete.

Client should first check the tuner capabilities. Will return KErrNotSupported in callback method if this feature is not supported.

Get the current Programme Identification code. RDS data is received over the air and may not be available immediately following tune operation. If data is not available, this function will return KErrNotFound. If a value is returned, this is the last known value, which may not be up to date. To be notified of the most recent value, client should use NotifyRdsDataChange.

Get the current Programme Service name. RDS data is received over the air and may not be available immediately following tune operation. If data is not available, this function will return KErrNotFound. If a value is returned, this is the last known value, which may not be up to date. To be notified of the most recent value, client should use NotifyRdsDataChange.

Programme Service name is fixed to 8 characters.

Get the current Programme Type. RDS data is received over the air and may not be available immediately following tune operation. If data is not available, this function will return KErrNotFound. If a value is returned, this is the last known value, which may not be up to date. To be notified of the most recent value, client should use NotifyRdsDataChange.

Get the current Radio Text. RDS data is received over the air and may not be available immediately following tune operation. If data is not available, this function will return KErrNotFound.

Subscribe for notification for the specified RadioText+ data. Client should first check the capabilities to see if RT+ feature is supported. Returns KErrNotSupported if RT+ is not supported.

Note that if the client wishes to receive the entire radio text data chunk, client should subscribe for ERsRdsRadioText using NotifyRdsDataChange instead.

Subscribe for notification for the specified RDS data. Client should first check the capabilities to see if a feature is supported. Request for notification for non-supported features will simply be ignored.

Starts radio playback.

Retrieve the current state of the player. If the radio is already playing, client should simply retrieve current settings such as volume, etc.

Request for control of a tuner. If this method returns KErrNone, control of the tuner has been granted. Control to the tuner must be granted before any other request can be made.

Turn on/off automatic switching of frequency based on Alternate Frequency. This will cause RDS device to search for alternate frequency when the signal strength deteriorates. User should be ready to receive RadioEventRdsSearchBeginAF and RadioEventRdsSearchEndAF. Automatic switching is off by default.

Turns on/off automatic switching of frequency based on Traffic Announcement. This will cause RDS device to search for frequencies broadcasting traffic announcement. Client will be notified of frequency change though the tuner event. It's up to the client to return to the previous frequency when the traffic announcement is finished.

NOTE: This is only supported in dual tuner configuration since the secondary tuner needs to perform continuous scanning for frequency broadcasting traffic announcement, while the primary tuner is used for normal tuner activities.

Set the speaker balance for playing.

Asynchronous request to set the frequency range. If the frequency range is not set, it will be defaulted to ERsTunerFM.
