![]() SMPTE connectors are commonly used in live broadcast applications. Two of the copper contacts are used to power the equipment, for instance the camera at a remote location, while two other copper contacts are used as a signal interface, to make sure the connector is correctly mated before sending the fiber optic signals.” “The contact configuration has both copper and fiber optic signal contacts. “The SMPTE connector is an industry standard used for national TV, theaters, and sport arenas,” said Buechli. LEMO produces hybrid connectors for the broadcast industry that meet technical standards set by the Society of Motion Picture and Television Engineers (SMPTE). The cables have to be robust and resistant to crush or impact, said Buechli. In busy event environments, common mishandling includes heavy trucks driving over cables, which can crush or bend the fiber and result in signal loss. He advocates using proper cleaning tools to rapidly clean the fiber optic ferrules, particularly if the connectors are unmated often.įiber optic cables are also fragile and can be damaged during the setup at venues. “For fiber, the most important feature is the cleanliness of the fiber interface small dust particles at the connection point will decrease the signal quality,” said Serge Buechli, business development manager at LEMO SA. ![]() ![]() LEMO developed the 3K.93C.Y Series SMPTE hybrid connector for HDTV applications. With copper, the attenuation constantly increases with the signal frequency. The signal attenuation is virtually flat until very high frequencies are reached. These characteristics have made it popular for broadcasting major sporting events, where the wide bandwidth can serve multiple channels with high-quality images and minimal latency over longer distances. It is also characterized by low signal loss and electromagnetic interference (EMI) immunity. The Rise of Fiberįiber optic cabling supports a wide bandwidth and has the capacity to handle high volumes of data. Machine learning is expected to bring new capabilities, such as the ability to monetize analytics, improve workflow efficiency, as well as enhance the viewers’ experience, he added. ![]() “Machine learning is a rapidly developing technology that is stimulating new usage models in pro A/V and broadcast,” said Ramesh Iyer, director of pro A/V and broadcast at Xilinx. These technologies enable region-of-interest encoding to detect faces and features intelligent digital signage to identify gender, age, and gesture detection automatic object tracking and window cropping to output multiple high-definition windows from a single 4K camera to switch content at live events and speech recognition for automated transcripts. They may also expect to see an inset image of what is happening in the track events while simultaneously watching the swim events on the main screen, which takes broadcast technology to another level.Īt Integrated Systems Europe (ISE) 2020, Xilinx, a processing platform company that invented the field programmable gate array (FPGA), introduced new broadcast and pro audiovisual (A/V) computing products with machine learning capabilities that can enhance broadcast quality even further. Today, when broadcasters transmit images from international events like the Olympics, viewers expect minimal latency, or delay in the flow of images. Things have changed dramatically since the days when long delays and grainy images were common during the broadcast of live events. Audiovisual equipment is integrating with increasingly sophisticated signal equipment to support 8K video and even machine learning. ![]()
