When Power Cord matters (French and English document) Nothing is more simple than a power cord ! But it’s not completely true when security matters. As a matter of fact, for equipment that is so important that requires redundancy, this parameter has to be considered. And who has never unplug a power cord by mistake? Particularly when synch generators are concerned, all details are important.

SpyderCube for HDR adjustments To balance video cameras, vision engineers typically use a grey scale test chart and a waveform monitor, which allows them to adjust multiple cameras identically with the same color grading. When shooting with High Dynamic Range, it is necessary to pay attention to the very bright picture parts, the so-called “specular highlights” that are brighter than the white bar with 90% reflectance in a grey scale test chart. In this context, a small accessory will become very useful and that is the trick we want to share with you today.

Last Firmware release Most of the measurement equipment’s are now operating with programmable microprocessor FPGA and it is necessary sometimes to check whether a new version is available in order to get it on the web. It appeared interesting for the NAB month to summarize the current production releases actually available on line.

UTC versus DST With such a title, an initial explanation is needed The UTC time is the Universal time taken at the Greenwich meridian in UK. Its former name was GMT (Greenwich Meridian Time) that was more explicit. Except that in summer, the time in Greenwich is one hour ahead because of a political decision. And it is precisely where DST comes, bringing a subtle nuance into the time actually used in certain countries.

NMOS IS-04 As our industry moves away from hard wired systems towards flexible IP based architectures, international standardization entities (like SMPTE or AES) have worked on specifications to stream live content on IP packets (ST2110). But they have not really worked about interconnection and interoperability: How for instance to know what is in a system or how to simply connect a camera to a monitor in this environment ? Facing this context, AMWA has created an open working group named NMOS to work on these subjects. The first published specification (IS-04) enables applications to discover networked resources, which is an important first step towards automation and scalability. Tektronix being one of the active members of this group, IS-04 is already implemented in the Prism to facilitate the network connectivity.

Picture BRIGHT-UP Now that pictures are created for high resolution displays and sometimes with high dynamic range luminance curve, we often receive the question about how to monitor carefully the levels in a video signal directly in the picture. There many ways to measure that and some are well known: Luminance Vector display (see T&T N°109), Diamond display, Spearhead display (see T&T N°66). But there is a particular display for long long time, in all Tektronix oscilloscopes that allows to check very rapidly the level of luminance in the picture itself. This is the bright-up possibility that is switched off by default.

FOM, a new index of performance All users of SPG8000A with the GPS option on board have seen on the menu and in the alert panel a new index of performance index that is FOM. At a high level, a Figure of Merit is an indicator that a manufacturer makes available for a user showing at a glance how the instrument is performing. It has no scientific value and the user must calibrate it for the different steps. This paper gives some inputs on this concept and how to use it for the SPG8000A.

Protocole IGMP IGMP is now implemented in measurement tools for monitoring the IP-based baseband video streams. This technique is widely used in the networking world and a short explanation about this subject seems today necessary for our broadcast industry, often unfamiliar with this type of protocol.

Stop Display The introduction of HDR cameras on the market adds to the difficulty to measure images and this is particularly the case if an operator has to adjust a mix of SDR and HDR cameras. Moving from one to the other, it will be extremely difficult for him to align the white levels similarly on the two types of cameras. The trick of the Stop display is that the waveform is no longer linear in millivolt, but logarithmic by setting the 0 (corresponding to the 80% white level) in the center of the screen, and that that scale will work for SDR or HDR cameras.
