GVSPMaxLookBack [Integer] R/W
Size of the look back window, in packets, when determining if a stream packet
is missing. When a stream packet arrives out of order, the driver skips back
GVSPMaxLookBack packets to see if the packets previous to this point have
all arrived. If not, a resend is issued. A lower value allows the driver less time to
assemble out-of-order packets; a larger value allows the driver more time. If the
value is set too low, the driver will issue unnecessary resends. If the value is set
too high and a packet truly is missing, the driver will issue a resend but the cam-
era may no longer have the required packet in its resend buffer and the packet
will be dropped. The ideal value is system dependent.
GVSPMaxRequests [Integer] R/W
The maximum number of resend requests that the host will attempt before
marking a packet dropped.
GVSPMaxWaitSize [Integer] R/W
Maximum number of received GVSP packets following a resend request to wait
before requesting again.
GVSPMissingSize [Integer] R/W
Maximum number of simultaneous missing GVSP packets before dropping the
frame (0 = OFF).
GVSPPacketSize [Integer] R/W
GVSP Packet size.
GVSPTiltingSize [Integer] R/W
Maximum number GVSP packets received from a following frame before drop-
ping the frame (0 = OFF).
GVSPTimeout [Integer] R/W
End of stream timeout. If no stream packet received before GVSPTimeout,
host requests resend, up to GVSPMaxRequests times. If still no packet
received from camera, packet is marked as dropped.
