UHD-4K SQD vs 2SI The Video industry is always trying to improve its level of quality. In this context, 4K UHD is now coming to our TV sets and the best example will be the next world cup in Russia in June that will be covered in 4K in all the stadiums and broadcasted to each country in its native format. 4K UHD requires 8 times more bandwidth than a regular HD signal. It means that 12Mbps are needed. If we remember the difficulties faced moving from SD-SDI (270Mbps) to HD-SDI (1,485Mbps), dealing with 12Gbps SDI could be considered as quite a challenge. Fortunately, for those now wanting to take any risk, some tips exist allowing well-known process, and a lot of broadcasters are using the 4 links 3Gbps technique. So, the signal is divided in 4 equal parts and transported on 4 different coaxial cables. Two modes exist for splitting the pixels, each of one with advantages and disadvantages.

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.

GPS antenna connection It is a FAQ to know what kind of antenna to use in a GPS installation and how to be sure that the signal at the input of the SPG is correct. It is important first to understand that the GPS receiver is inside the SPG8000A itself and then the available connector on the back side is an Antenna connector. Knowing that, it is important to take some elementary cares about how to wire the antenna in the generator.

SDI outputs – Which one to use ? (French and English document) Since scopes are now 3G compatible, a passive loop-through is not possible anymore because at these frequencies the metallic continuity would represent a real antenna bringing a lot of interferences in the signal. The waveform monitor outputs are then all active and it means that without mains, no signal is available on these connectors. But there are many output connectors. So witch one to select and how to choose and to set the right one ?

Video on optical fiber measurement (French and English document) Because optical connection solutions are easier to use and manipulate, they are becoming increasingly popular in the broadcast industry. Nevertheless, when a difficulty occurs in deploying the solution, it is useful to have an equipment able to check the main parameters of the transmission path. This is precisely what the SFP option of the WFM2300 does and here are some tricks on how to use it appropriately.

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.

DARS phase evaluation (French and English document) The DARS signal is sometimes created in another equipment than a SPG. In this case, it is necessary to check regularly the phase of this DARS compared to the video Sync of the system. As a matter of fact, these two signals must be synchronous and stable otherwise clicks and pops suddenly appear. But this is not easy to do so, since one signal is analog and the other is digital, and on top of that it’s necessary to compare the BB with the content of the AES signal and not with the clock ! The trick to do that is to use a traditional oscilloscope able to trigger on a user-defined pattern in a digital stream.
