The VIDEOMETA message is used to transfer video meta information which are not available in video message type, such as patient name, medical record number, camera focal length, zoom factor etc. An VIDEOMETA message can contain meta data for multiple video sources. This message type may be used to obtain a list of videos available in the remote system, such as video database, laparoscope or commercial image-guided surgery (IGS) system.
| Data | Type | Description |
|---|---|---|
| NAME | char[64] | Name or description of the video |
| DEVICENAME | char[64] | DeviceName to query the VIDEO and COLORT |
| PATIENT_NAME | char[64] | Name of the patient |
| PATIENT_ID | char[64] | ID of the patient |
| ZOOM_LEVEL | int16 | Defines the zoom level of the camera. |
| FOCAL_LENGTH | float64 | Defines the focal length of the camera in millimeter. |
| RI, RJ, RK | uint16[3] | Number of pixels in each direction |
| TX, TY, TZ | float32[3] | Transverse vector (direction for 'i' index) / The length represents pixel size in 'i' direction in millimeter |
| SX, SY, SZ | float32[3] | Transverse vector (direction for 'j' index) / The length represents pixel size in 'j' direction in millimeter |
| NX, NY, NZ | float32[3] | Normal vector of video frame plane(direction for 'k' index) / The length represents pixel size in 'z' direction or slice thickness in millimeter |
| PX, PY, PZ | float32[3] | Center position of the video frame (in millimeter) (*) |
| S | uint8 | Scalar type (e.g. 3:uint8, 5:uint16, same as in VIDEO) |
| -- | uint8 | Reserved |
- More than one item can be transmitted. The number is bodySize/itemSize.
- To get the VIDEO, GET_VIDEO is used with the Id in the device name field.
GET_VMETA is used to query for meta data of video sets. If DEVICE_NAME in the header is empty, a list of meta data for all available video sources is returned.
