Burst Mode can enabled or not and applies only to the ASI output. In Burst Mode
the Transport Stream file is streamed out in a packetized way where a packet is the
same size as a Transport Stream file: that is 188 bytes. In this mode there is no stuffing
between bytes of a packet. Stuffing is only present between packets. When Burst Mode
is No the file is sent byte after byte and stuffing is inserted between bytes. This mode is
named ASI Spread Mode in literature. The stuffing I mention here exists only at physical
level and it is never present at application level. Note that this stuffing has nothing to do
with null packets in a Transport Stream file.
The Status section displays information about what the player is doing: playing,
stopped, paused.
The progress bar shows how much of the file has been streamed out.
The Hardware Alarms sections contains two items that can be green or red. When
green there is no error, if red there is some problem. This alarms are at hardware level
and they are polled every second or so. If Synchronization alarm is red it means that the
Transport Stream packets of 188 bytes length are not well formed because they lack the
starting synchronization byte which is a 0x47. If the Buffer alarm is red it means that the
Card is not able to stream out the file at the desired speed. Currently, the maximum
transmit speed is 90 Mbps. If the processor is heavily loaded doing some other task the
maximum transmit speed will lower. If the hard disk is really a bad quality one the
maximum speed will also get smaller. When simultaneously playing and recording a file
the maximum combined rate is about 80 Mbps say 40 Mbps for the player and 40 for
the recorder.
