:PLAY:SSPOsition:TIME <string>,<string>
Sets the loop start and stop positions of the selected stream to be looped by
time (hh:mm:ss). Specify the start time in the first argument and specify
the stop time in the second argument. You can set the time from 0 to
(available maximum value of the selected stream file). The default values
are both 00:00:00.
:PLAY:SSPOsition:TIME?
Returns the current loop start and stop position settings of the selected
stream by time (hh:mm:ss).
:PLAY:STANdard?
Returns the standard of the loaded stream file. The available responses are
MPEG, ARIB, ATSC, DVB, NONTs, MTMCc, STMCc, or ISDBT. The
MTMCc, STMCc, and ISDBT standards are checked only when the
:SYSTem:STANdard command is set to ARIB.
:PLAY:STARt
Starts outputting the selected stream. There are no arguments.
:PLAY:STOP
Stops outputting the selected stream. There are no arguments.
:PLAY:SYNC TSPAcket|SF|NONTs
Sets the format of the PSYNC signal output from the SPI In/Out connector.
For TSPAcket, a single pulse signal is output at the start point of each
packet. For SF, a single pulse is output at the start point of the SF appearing
every 204x48x8 bytes. For NONTs, you can set the output period and data
width of the PSYNC signal using the :PLAY:SYNC:PSYNc:INTerval
command and :PLAY:SYNC:PSYNc:WIDTh commands. SF is available
only when MTMCc is returned by the :PLAY:STANdard? query. The
default value is TSPAcket.
:PLAY:SYNC?
Returns the current format setting of the PSYNC signal.
:PLAY:SYNC:DVALid:WIDTh NONE|<numeric_value>
Sets the status and data width of the DVALID signal when NONTs is
selected in the :PLAY:SYNC command. When you select NONE, the
DVALID signal is disabled. You can set the width from 16 bytes to 255
bytes. This value cannot be set more than the value set by the
:PLAY:SYNC:PSYNC:INTerval command. The default value is 188.
