     - fixed power down/up modes for the tuner HW
     - sample rate will be set to 32MHz only
     - VBI bugfix for WHQL

     - VBI pin can be connected to CC decoder and WST
       at the same time via a smart tee
     - Added SECAM D/K support to the silicon tuner

Note: Be sure that a NTSC signal is connected to the S-Video
      input during the WHQL

Version  01/30/2004
WDM: - Uncorrect GPIO object has been used to feed the
       GPIO layer
	 - Volume, treble, mute, bass and dolby pro logic has
	   function via the audio device properties
	 - Added private interface for PHILIPS_KSPROPERTY_ITEM_VIRTUALFLAG
	 - Added silicon tuner support with FM radio ( tested on application
	   board from Philips with the TV/FM radio switch on GPIO 21)

       of the overflow buffers

TunerLib: - Corrected FM frequency offset

Notes: - For WHQL make sure the default country code on the system
         is supported in the tuner front end, due to the fact the "Blink"
	     test, checks in the Tuner interface test the default country, if
	     it is selectable via the SetCountry code property.
	   - The silicon tuner is tested on the reference design from Philips
	     only and also the FM radio part is tested in Germany only.
		 The FM radio mode via SIF will be activated and configured
		 with the folllowing registry entry:

		 "FM Radio IF" = 0x729555 (5.5MHz) (default value: 0xdeeaab 10.7MHz)
		 e.g.: HKR, "Audio", "FM Radio IF",0x00010001,0x729555

Version  01/16/2004

     - Added Audio device properties (mute, treble ...),
	   but still under testing

SAA713x Release Notes (Version 2.2 / 01/29/03)


 - CAbstractGPIO class added: GPIO interface methods are now accessible in DDK.

   format table dynamically, just as CKSVideoOut does).

 - Object status is a DWORD in all classes.

 - Object status is a DWORD in all classes.

 - Object status is a DWORD in all classes.


 - Initialize the audio stream even if there is no audio out pin (SAA7130).


 - Reset m_llThroughput on Stop, not on Start, just as m_cDropped and m_cTotal,
to avoid
   division by zero when s.o. calls PROPSETID_VIDCAP_DROPPEDFRAMES after Stop.
 - Set the Adapter pointer in our HwDeviceExtension to NULL, when deleting the
Adapter object..
 - Parameter check for GUID_SEND_VIDEO_STANDARD.
 - Renamed PhilTune.* to PhTVTune.*.
 - Always start with even field, if EITHER_FIELD.


 - VBI format changes to circumvent crash at Start/Stop with CCDecoder which
   occurred when there was a PAL signal at the time GraphEdit was opened:
   - Expose 3 different VBI formats.
   - In SetFormat() set stream parameters according to the format to be set, not
the actual videostandard.
   - GUID_SEND_VIDEO_STANDARD property ignored.
   - Format intersection ignores actual video standard and accepts the proposed
format as is.
     (everything is checked in QueryAcceptFormat()!)
   - OnAcquire() fails if video standard doesn't fit.
   - OnRead() fails, if buffer is too small.


 - Reset dropped frame count on Stop, not on Start, so it will not be reset
after pause (HCT 11).

 - Use 4 bytes for dending country code or video standard from phtvtune to
 - Fix for FM1216ME / FM Radio: IF Gain = 1

 - Shibasoku TG19 workaround for all DSP-Versions.
 - Bugfix: When updating the DMA address registers of a new buffer,
   the byte order is also updated according to the buffer format settings.

overflow buffer
   will be used and the default byte order of this dummy buffer would be set for
all subsequent buffers.


 - Search for all audio standards, if video standard is unknown.
 - Handle standard, country and tuner mode information from tuner driver.
 - No extra crossbar pin for FM Radio (use TV Audio In).

standard detection.
 - Send Tuner mode information to the capture driver for proper FM Radio

 - Handle FM Radio seperately.
 - Add AUDIO7134_IN_FM_RADIO AudioInputSelect.


 - Create C34PortVideo object already in constructor -> Blink test!
 - Improved workaround for EIAJ: check both the DUAL and the STEREO status bits.
 - Use flexible audio format table, but don't call
StreamClassReenumerateStreams() on source change,
   as this function crashes the system. So we end up in supporting only 32 and
48 kHz for now.
 - Changed TV Audio property to support the standard TV Audio dialog (which
 - Add sanity check in Cap7134Adapter::CurrentFrameInterval().

and StrideInBytes on FIDT change.

standard before Open().
 -                   QueryAcceptFormat() checks, whether dataformat is
compatible with the video standard. (No line 22 for
 -                   Workaround for CC bug only if registry flag is set.
HAL: Allow up to 8 devices instead of 4.
 - Don't call CheckBufferInTime() for VBI stream with time stamps.
 - Workaround for DSP bug implemented: EIAJ standard not detected in ASD mode on
Shibasoku TG19 test generator.
   For video format NTSC_M_J try SSS mode and EIAJ, fast ident speed, first. If
not successful, proceed as usual.
   (uses Timeout Callback routine parameters, see above)

Typ AudioChannelMode erhaelt zusaetzlich den Wert AUDIO7134_CHANNEL_C.
Zusaetzlich zum Typ AudioChannelMode gibt es den Typ AudioChannelSelect
(bitfield: Mono/Stereo | LangA/B | SAP).
Set/GetChannelMode() setzt/liefert den ausgewaehlten ('preferred') mode
Obsolete Property PHILIPS_KSPROPERTY_AUDIO_SAP entfernt.

AudioChannelMode m_mode wird ersetzt durch:
AudioChannelMode m_eChannelMode (tatsaechlich in der HW eingestellter Mode)

SetChannelMode() wird ersetzt durch SetChannelSelect()
Zusaetzlich zu GetChannelMode() gibt es GetChannelSelect()
Nur noch ein m_nADspSignalSource fuer alle Pfade.
SetRouteInput() wird nicht mehr direkt aufgerufen (nur ueber AudioHAL).
Obsolete Property PHILIPS_KSPROPERTY_AUDIO_SAP entfernt.

CAudioHAL weiss nach wie von nichts von AudioChannelSelect; CAudioOut setzt
den AudioChannelMode gemaess selektierten modes + anliegendem Signal.
CAudioHAL::SetStreamSettings(): X3 Stereo und Phantom Center werden
	DigitalMatrix wird nach Bedarf von MAIN auf AUX1 und/oder AUX2 kopiert.
	m_nCaptureOption wird beruecksichtigt.
CAudioHAL::SetChannelMode(): DM fuer DPL ist immer STEREO
	Im Falle Direct Audio gilt der channel mode auch fuer AUX1.
	Fuer SAP wird SetRouteInput( DSP_SS_SAP ) fuer die entsprechenden Pfade
	Fuer All Languages werden AUX1 und AUX2 unabhaengig von channel gesetzt.
SetRouteInput() wird nur noch zentral von CAudioHAL::SetChannelMode()

Fuer X3 Stereo und Phantom Center werden nur 3 Kanaele gebraucht; Unterscheidung
zu All Languages durch ChannelMask.

TVAudio Property:
SetAudioMode() setzt AudioChannelSelect, nicht AudioChannelMode.
GetAudioMode() benutzt die Methode des AudioStreams, nicht die der HAL
