Abstract:
1. A method for filtering a video synchronization signal sent from a remote computer to a plurality of graphics processing computers, each graphics processing computer having at least one graphics processing card and a sync filter, comprising the steps of: receiving a stream of at least n sync signals from the remote computer; storing the most recently received n sync signals in an array; comparing an n+1 sync signal with each of the n sync signals in the array to form a comparison for each of the n sync signals in the array; replacing an oldest of the n sync signals in the array with the n+1 sync signal; and using the n+1 sync signal to synchronize the at least one graphics processing card in each graphics processing computer with each at least one graphics processing card in the plurality of graphics processing computers if the comparisons of the n sync signals in the array are greater on the average than a preset threshold.
