About the Data Output Source
When you output the selected stream data, you can select either the hard disk or
the RAM as an output source. This subsection describes the operation of the
MTX100 when each output source is selected.
When you select the RAM as an output source, the MTX100 performs the
following:
When data output rate is less than or equal to 120 Mbps, the MTX100
outputs the first stream data while transferring the data from the hard disk to
the RAM and then continuously outputs the data from the RAM using
looping methods.
When data output rate is more than 120 Mbps, the MTX100 continuously
outputs a stream data from the RAM using looping methods after the data is
completely transferred from the hard disk to the RAM.
If you select the RAM as an output source, you cannot output the data over the
RAM free space for the data output. This RAM free space is displayed on the
status bar. Refer to Status Bar on page 2-9, for more information about the
status bar.
If you select the hard disk (Disk) as an output source, the MTX100 always
outputs the selected stream data from the hard disk regardless of the data output
rate. When the reading speed of the hard disk cannot overtake the data output
rate, the error message “Error: Output Buffer Empty” appears.
Use the Source command in the Play menu to select the output source. Refer to
Play Menu on page 3-5 for more information about the Play menu.
You can see the currently selected output source in the status bar. Refer to Status
Bar on page 2-9, for more information about the status bar.
