ASCB Receive Sampling Structure. More...
#include <mxf_class_ascb.h>
Data Fields | |
| uint64 | timeTag |
| uint32 | control |
| uint32 | rate |
| uint32 | errorCount |
| uint32 | dataSize |
| uint16 | data [256] |
This record structure is returned by the sampling service.
| MXF_ASCB_SAMPREC::timeTag |
Specifies the time when the data record has been received by the device. It is an absolute time expressed on the timebase set for the device.
| MXF_ASCB_SAMPREC::control |
The control field defines the condition under which the related record data was received.
The control bits are defined as follows:
| Bit constant | Description |
|---|---|
| MXF_ASCB_RX_REC_CTRL_HWCRC_ERROR | The message was received with a bad hardware CRC. |
| MXF_ASCB_RX_REC_CTRL_DATACHKSM_ERROR | The message was received with a bad data checksum. |
| MXF_ASCB_RX_REC_CTRL_DATACRC_ERROR | The message was received with a bad data CRC. |
| MXF_ASCB_RX_REC_CTRL_FC_ERROR | The message was received with an invalid FC. |
| MXF_ASCB_RX_REC_CTRL_FRAME_ABORT | An abort sequence was detected (no closing flag). |
| MXF_ASCB_RX_REC_CTRL_SYNC_LOST | A sync lost was detected before the end of the message. |
| MXF_ASCB_RX_REC_CTRL_BYTE_COUNT_ERROR | The message has a an invalid byte count. |
| MXF_ASCB_SAMPREC::rate |
Time between the reception of the last two records expressed on the timebase (microseconds or nanoseconds). The maximum is about 4 seconds in nsec or 4000 seconds in usec.
| MXF_ASCB_SAMPREC::errorCount |
Total error count. See control field for a list of detected errors. Increment by one even if there is more than one error in the message.
| MXF_ASCB_SAMPREC::dataSize |
Number of bytes received in data array.
| MXF_ASCB_SAMPREC::data |
Data received.
