Examples:

ar664_sampling.c, and ar664_sampling.cs.

Field Documentation

uint64 MXF_A664_SAMPREC::timeTag

Specify the time when the data record has been received by the device.
It is an absolute time expressed on the time base set for the device.

Examples:

ar664_sampling.c.

uint32 MXF_A664_SAMPREC::control

The control field report the state of the frame that was received on the physical port.
The frame status control bits in sampling are defined as follow;

Constant	Description
MXF_A664_CTRL_RX_PORT_B	The frame is coming from physical port B. If this bit is not set, the frame is coming from physical port A.
MXF_A664_CTRL_RX_CRC32_ERROR	Frame CRC32 error detected
MXF_A664_CTRL_RX_PREAMBLE_LENGTH_ERROR	Preample too long
MXF_A664_CTRL_RX_SFD_ERROR	SFD error detected
MXF_A664_CTRL_RX_FRAME_TOO_LONG_ERROR	Frame > 8192 bytes received
MXF_A664_CTRL_RX_MAC_SKEWMAX_EXCEEDED	The frame has been received after MAC Skew Max elapsed
MXF_A664_CTRL_RX_EDE_SKEWMAX_EXCEEDED	The frame has been received after EDE Skew Max elapsed
MXF_A664_CTRL_RX_FRAGMENTATION_ERROR	Bad fragment detected

uint32 MXF_A664_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.

uint32 MXF_A664_SAMPREC::errorCount

Reserved for future use.

uint32 MXF_A664_SAMPREC::dataSize

Number of bytes received in data array.

Examples:

ar664_sampling.c.

uint64 MXF_A664_SAMPREC::reserved[2]

Reserved for future used.

uint8 MXF_A664_SAMPREC::data[8192]

Data received. Udp payload.

Examples:

ar664_sampling.c.
