optimise the timings.
The Lindos sequence system is now in widespread use by several major broadcast and
telecommunications companies world-wide, in addition to the hundreds of smaller
manufacturers and studios, and it has become the industry standard. It is suitable for line
testing, but unlike the O.33 specification, Lindos sequences can also be used to test tape
machines which may have large speed errors (up to ±4%). Our system is also more
flexible because it allows the user to build test sequences from test segments, thus
enabling a sequence to be designed which contains only the tests which are required and
relevant for the device being tested (wow & flutter and MOL test segments for example,
which can be used to test tape machines, but clearly would have no place in line testing).
For these reasons, and because of its greater flexibility, the Lindos system is felt to offer
better performance at lower cost, and the O.33 sequence will not be included as standard,
though compliance with the CCITT and EBU measurement standards will be maintained
as far as possible.
