3.15.4.2 Profiles

Profiles define the data rate of the encoded stream, the video and audio encoding of the signal and many more parameters. The software uses a profile by applying a preset to the devices representing the end points of the upcoming connection.

To make a profile universally usable, presets with the name defined in the profile must be present for all types of encoder/decoder equipment used by the software. The software checks this when a new profile is defined.

There are device types which contain multiple encoders or decoders in one device frame. The software knows about these device types and expects a preset "NAME" to be present as "NAME-1", "NAME-2" ... "NAME-n" for all encoder or decoder instances this device may contain.

The profile definition section is located in the bottom right corner of the window. It shows the list of defined profiles, selecting a profile in the list shows the properties of this profile right beside the list. You may edit the properties of the selected profile to your needs. The profile is uniquely identified by its ID, this cannot be changed once a profile has been defined.

• id: The profile ID internally identifies the profile. It cannot be changed once the profile has been created.
• name: The profile name is shown in the VioIP Client Application in the list of active connection and it is used to select a profile when the operator starts a connection with the "Activate selection (user defined)" button.
• total data rate (MBit/s): In this field enter the total data rate the encoded signal occupies on the data lines between the locations. The rate must match the data rate produced by the encoder preset and must include the rate of all contained streams including the transport stream format overhead. This is not the video data rate!.
• preset: With this field the name of the preset to be used for this profile is defined. The software presents a drop down list with all presets it finds for the device types known to be used as encoders / decoders within the VioIP software. The entry field also permits to overwrite the name and set a preset name which is not yet present. When the preset name is changed - either by entering a new name or by selecting a name from the list - the software checks if this preset is available for all known encoder / decoder device types. If not the software displays a warning. This means, you can define a profile which has the referenced presets not or not completely defined, but you are warned: You will not be able to start a connection with this profile if the referenced preset is not available for either the source or the destination device.
• groups: A VioIP Client Application will only permit to use this profile if the group ID the client has been started with appears in this list. This way you may define different profile settings for each particular group, each group will only see the profile definitions it has been granted permission. You may use the "Add" / "Del" buttons below the groups list to add or delete groups for this profile. If the group list of a profile is empty, it cannot be used.

With the blue arrow buttons below the profile list the selected profile can be moved up and down in the list. The topmost profile in the list is considered to be the default which is used for connections the operator starts without the "user defined" option.

The button "Add" lets you add a new profile. The program shows a dialog window where you can enter the ID for the new profile. An ID entirely consists of upper case letters and digits, the "-" character is allowed as a separator. The ID must be unique, you cannot define two profiles with the same ID. The ID also is unalterable, once you defined a new profile you cannot change the ID of the profile later.

The button "Del" lets you delete the selected profile. The program shows a query dialog before the profile actually gets deleted. Deleting a profile does not delete the preset definitions referenced by this profile.
