Picture Quality BRISQUE is a concept developed by the University of Texas to evaluate in real time and without reference the quality of a video sequence. Based on these algorithms, Tektronix introduces a new TekMOS measurement index that takes into account the quality of the image once decoded and not in its compressed data stream.

Subliminal Picture Detection The use of subliminal pictures appears in the news regularly although their effectiveness has never been truly proven. Indeed, the law prohibiting them on television was born after a pseudo-study of an American who proved to be completely made up. It is therefore more a matter of precaution than anything else. But the law is the law and publishers are severely called to order when they happen to broadcast such images.

UHD test signal generator A valid test signal is one of the first requirements when starting the evaluation and/or the deployment of a new signal format. Thus, since UHD is arriving in production studios, it would be convenient to have a UHD color bars pattern available. However, a specific UHD signal generator appears to be an overkill for a simple test or occupancy signal. For this reason, a tip in the SPG8000A allows to generate a valid UHD bar chart using its SDI option.

PTP – A new reference (French and English document) To deploy systems interconnected with IP links, the most difficult issue to solve is synchronization of all the equipment’s with a unique clock. With this in mind, an old standard has been adapted for Broadcast applications: PTP (Precision Time Protocol). Originally, this technology has been used by banks for High Frequency Trading operations in order that all computers in the world have a unique clock that is millisecond accurate. This protocol has now been adapted for Broadcast applications and is well described in the recommendation SMPTE ST 2059-2.

TS-DF measurement (Time Stamp Delay Factor) (French and English document) In our Broadcast industry, the advent of IP transport requires to adapt to new techniques and to become familiar with new indicators. The IP has a long life and measurement techniques too. However, new algorithms had to be developed in order to adapt to Broadcast. It is in this context appears now the TS-DF indicator that measures the jitter of a network and its cumulative effect over time.
