5. The software may be able to prepare the crosspoint data and send it to the hardware when that vertical field mark occurs but the hardware itself typically has a one field delay in it so the soonest that such a crosspoint would switch would be one field plus a little from when it was received If the command were received towards the beginning of a field rather than the end of a field the delay would be closer to two fields Industry parlance is to call this a one field delay because only full fields of delay are counted The delayfields argument of this command takes into account the hardware delay So if a router has a minimum delay including the hardware delay of one full field as described in the previous paragraph then a delayfields value of 1 causes this minimum delay to be used A delayfields value of 0 will also cause this minimum delay because the router uses its minimum if a smaller value is specified A delayfields value of 2 however will add one more field to the minimum possible delay Thus delayfields specifies the number of full fields of delay between end of crosspoint command string received and crosspoint switch occurs Note that the actual minimum value of delayfields depends on the particular router model Routers typically have a limit to the number of crosspoint commands they can process in one field First there is an inherent delay in sending the command to the router but beyond that the router requires time to p

Results There are many factors affecting the quality of results when signals are transmitted from a source to a destination CAUTION Signal cables Use only the best quality cables to avoid interference and degraded signal quality and elevated noise levels Sockets and connectors of the sources and destinations Use only the highest quality since zero ohm connection resistance is the target Connectors should also match the required impedance 75 ohm in video to minimize return loss Amplifying circuitry must have quality performance when the desired end result is high linearity low distortion and low noise Distance between video sources and destinations Plays a major role in the final result For long distances over 15 meters between sources and destinations special measures should be taken to avoid high frequency cable losses These measures include using higher quality cables and or adding line cable equalizing amplifiers Interference from neighboring electrical appliances These can have an adverse affect on signal quality Balanced audio lines are less prone to interference but unbalanced audio should be installed away from any main power lines electric motors transmitters etc even when the cables are shielded Only an authorized Sierra Video technician can service the switchers Any user who makes changes or modifications to the unit without the expressed approval of the manufacturer will void the

22. arse the command and buffer up the crosspoint data plus it requires time to deliver the buffered data to the hardware when the desired video field arrives Each individual router has documentation to describe its limitations on how many crosspoints it can process in a given amount of time Larger values for delayfields give the router more time to process commands Although the long term average number of crosspoints that can be processed per unit of time is unchanged a larger delayfields value can improve router performance during a short burst of many crosspoint commands For example suppose a large number of crosspoint commands is sent to the router in a single large command If delayfields is small the router typically wonit have time to parse and process all these crosspoint commands and place the data in the crosspoint delivery buffer before the target video field arrives By making delayfields larger the user can give the router more time to process the crosspoint commands 29 SIERRA VIDEO If too many crosspoint commands are received and the router is not able to process them fast enough it will output the crosspoint connections as soon as it can Unexpected delays in crosspoint output are a sign that the router is being pushed beyond its limits The fielddelay value applies to the entire router not just to the control port on which the F command is received It is therefore recommended that a single value be settled on for the
