segment 214 and substantially simultaneously disables the crc module 308 the crc module 308 now having two complete data fields 204 and 206 collected therein will load their associated accumulated check sums into the register 324 the system 300 provides bench testers with a technique to specify the number of data fields that will be examined for checksum analysis it also provides the bench testers with a mechanism to ensure that the number of checksums that are analyzed are representative of complete data fields the ability to specify the number of data fields and the ability to collect checksums from complete data fields produces more consistent and reliable bench testing results this approach due to its consistent results can be used to automate the testing or software hardware qa quality assurance for video products which traditionally require testers to perform visual inspection fig5 is a flow chart of an exemplary method 500 of practicing the present invention in fig5 the crc analysis system 300 stores a desired number of fields requiring crc analysis in the register 302 as illustrated in block 502 next video pixel data 310 is received in the crc module 308 as indicated in block 504 the detector 312 senses the received video.
