19 – OSD position. Set horizontal and vertical position for the next OSD object (text or picture). The
starting point is the left top corner of the captured video.
20 – OSD Text controls.
“A” field allows setting text and picture transparency on 16 levels (from 0 to 255). 255 value is fully
opaque. “Bg A “field allows setting text background transparency on 16 levels (from 0 to 255).0
value means that you will see only text character on video without any background.
Other buttons allows changing font, size, colors and style (italic or bold)
Replace <OSD Text> by the text string to overlaid.
Load Text button will apply the text following the current configuration.
21 – Display “Device Status” parameter status. This parameter of the device component indicates
the current state of the communication between card and system. It can take following values:
- 0 for "OFF"
- 1 for "Ready"
- 2 for “In Progress"
- 3 is not used
- 4 for critical error.
Application should verify that this parameter is in ready state before applying any command.
In the same way, application should wait for “Device and Encoder ready “event (code 0x12000000)”
before applying any command to the encoder.
22 – Device Internals parameters.
This section display values of some basic status parameters of Device component such as:
“VideoMixer Microcode Version” – This parameter indicates version of bitstream of video mixer
module. This bitstream is loaded by application.
“SDI Camera” – refer to note 1&2 hereunder.
“Analog Camera” refer to note 1&2 hereunder.
“AudioFormat1" – This parameter indicates type of embedded audio. (PCM or AC3)
“Pci Microcode Version” - This parameter indicates version of bitstream of IO card (VML-7040 card).
This bitstream is stored on a flash of the IO card.
"Board Id" – Give hardware revision of IO card.
These parameters are not visible in the Livewire Setting pages as they are declared as Internal.
However, application can retrieve their value through get_ComponentParameter method from
Assembly Container.
23 – Capture Duration.
This parameter set duration in second of next MPEG Encoding. 0 means that encoding will not stop
automatically.
Note1: The board device has 2 parameters named “SDI Camera” for SDI detection value and
“Analog Camera” for composite detection value.
The SDI video resolution detection value could be:
DIN_1080I (2048): 1920x1080, 2 fields
DIN_1080P (1280): 1920x1080, 1 frame
DIN_720P (768): 1280x720, 1 frame
DIN_576I (2304): 720x576, 2 fields
DIN_480I (2560): 720x487, 2 fields
720x507, 2 fields
