Editing/Creating Profile

 Top 

- enables Editing of an existing Profile, or Creating a new one.

 

Edit profile dialog:

 

editprofile002

 

Profile entry parameters:

 

Profile number:

The CODEC_NAME_ARIAL12_001 assigns a Profile number automatically, which cannot be changed by the user.

 

Profile name:

The maximum length of a Profile name is 20 characters.

 

Profile algorithm:

- set Profile algorithm to:

•G.711 (i.e. digital telephone)
•G.722
•MPEG1/2 L2
•MPEG1/2 L3
•AAC (only available at CENTAURI 300x and 400x)
•AAC (LD); must be enabled by a key code via Expert/Set Key Code
•MP3 Pro; must be enabled by a key code via Expert/Set Key Code
•AAC (HE); must be enabled by a key code via Expert/Set Key Code
•Linear; must be enabled by a key code via Expert/Set Key Code
•4SB ADPCM;must be enabled by a key code via Expert/Set Key Code
•APT-X; must be enabled by a key code via Expert/Set Key Code
•Enh. APT-X 16; i.e. enhanced APT-X with 16 bit; must be enabled by a key code via Expert/Set Key Code
•Enh. APT-X 20; i.e. enhanced APT-X with 20 bit; must be enabled by a key code via Expert/Set Key Code
•Enh. APT-X 24; i.e. enhanced APT-X with 24 bit; must be enabled by a key code via Expert/Set Key Code
•AES/EBU transparent; must be enabled by a keycode via Expert/Set Key Code
Note:
At transparent AES/EBU streaming a special clocking scenario is necessary. Please find more info in application note 23 on Mayah Website (www.mayah.com/content/download/pdfs/appnotes/centauri/a_n_e_023.pdfwww.mayah.com/content/download/pdfs/appnotes/centauri/a_n_e_023.pdf).
•DRM; must be enabled by a key code via Expert/Set Key Code
•None means that the refering encoder or decoder is deactivated

 

Profile sample rate:

- sets the Profile sample rate.

 

Profile bit rate:

- sets the Profile bit rate.

 

Profile Bit Resolution

At linear also the bit resolution can specified if system version is >= 3.2.0.21. For this the bit rate list box must be right mouse clicked to open a popup menu.

Following selections are possible:

•8
•12
•16 (default)
•20
•24

 

Profile mode:

- sets the Profile mode.

 

Standard:

•mono
•dual mono
•stereo
•joint stereo

 

Multi channel:

Multi channel can be used with all APT-X algorithms, linear, AAC (MPEG4) and AAC (HE) provided the refering additional function is enabled (see menu item Expert/Set Key Code). Multi channel audio applies ADAT interface.

•MC 4:
4 audio channels are used.
•MC 4 CPE:
4 audio channels in CPE mode are used. CPE (= Channel Pair Element) means that a front and rear audio channel pair is encoded. This mode is just available for AAC (MPEG4) and AAC (HE).
•MC 4 MPEG:
4 audio channels are used. In this context MPEG means that a center, a right, a left and a rear audio channel is encoded. This mode is just available for AAC (MPEG4) and AAC (HE).
•MC 6:
6 audio channels are used.
•MC 8:
8 audio channels are used.

 

Profile IMUX format:

- sets the Profile IMUX (Inverse Multiplexer) format to one of the following:

•Auto
•CDQ/H.221
•Musictaxi
•J.52
•Micda
•APTX

[Inverse Multiplexing is necessary for the correct synchronisation of multiple B-channels in an ISDN transmission. If the IMUX format is set to Auto, the CODEC_NAME_ARIAL12_001 will auto-sense the correct format.]

Exception 1:

If a CODEC_NAME_ARIAL12_001 is establish a connection to a CDQ Prima set to MPEG-1/2 Layer II, and line format is H.221, then CODEC_NAME_ARIAL12_001 must be configured with:

•Algorithm:        MPEGL2
•Bit rate:                384 kbit/s (even if a smaller bit rate is set at Prima side)
•IMUX:                CDQ/H.221

Exception 2:

If you dial into a APT-X codec, the IMUX format must be set APTX.

 

Profile audio type:

- sets the Profile audio (i.e. source for Encoder and destination for Decoder) to one of the following:

•analog
•TOSlink (i.e. optical digital input)
•AES/EBU (i.e. balanced electrical input)
•ADAT (ADAT interface, uses optical port)
•none (only available if system software >= 2.2.0.10)

Note:

None means that the profile does not set the audio input or output.

 

With ADAT the following channel combinations are possible:

1) Standard:

•2 channels:ADAT12, ADAT34; ADAT56 .. ADAT2324

2) Multi channel (see item mode in menu item Settings/Codec):

•4 channels: ADAT14, ADAT58
•6 channels: ADAT16
•8 channels: ADAT18

 

Profile coder follows:

- sets the Profile dependency to either:

•remote, or
•local

In Remote mode, CODEC_NAME_ARIAL12_001 uses FlashCast technology, which means:

•codec_name_arial12_001/codec_name_arial12_001 and codec_name_arial12_001/SendIt transmission:
the ‘dialling codec_name_arial12_001’ passes over its’ parameters to the receiver.
•codec_name_arial12_001/non Mayah Codecs transmission:
codec_name_arial12_001 evaluates the settings of the other side and configure itself automatically.

 

In most cases remote is the optimum setting.

 

Profile ancillary data format:

- determines how to Encode/Decode the Ancillary (auxiliary) data carried in the audio data stream.

The following settings are permitted:-

•Auto
(detects the ancillary format automatically, provided a MPEG format is used; this does not work with APT-X ancillary data)
•CCS
•J.52
•Musictaxi
•Barco
•None (only with APT-X algorithms)
•Left (only with APT-X algorithms)
•Right (only with APT-X algorithms)

 

All entries becomes valid by clicking the OK-button.
