In aperiodic mode the user application is in complete control of the transmission.
The mxfHFCETxAperiodicWrite() function is used to send a FIFO buffer containing one or many HFCE records.
After the application is initialized and the channel is set, the application must allocate a buffer for MXF_HFCE_DATAREC record objects. The HFCE words are stored using the data
field.
The transmit timing is controlled by the record timeTag
field in conjunction with the startTime parameter of the function mxfHFCETxAperiodicWrite().
The aperiodic modes of transmission can be defined as follows:
In this mode, a relative start time can be specified to send the records. The records are then sent back-to-back. The record's time tag can't be used.
Transmission with Absolute Timing
In this mode, an absolute start time is specified to send the records. The records are then sent back-to-back. The record's time tag can't be used.
Transmission with Record Timing
In this mode, each record's time tag is set in the future (in sequence) for the transmission of the records. The start time can't be used with this option.
Transmission with Record Relative Timing
With this method, the records' time tag specify the relative time between each records for transmission. The start time can't be used with this option.
