The concept of multiviewer traditionally brings us to think on a system capable to make a display many TV signals on a screen, and eventually make a monitoring of the audio level and place the name of the signal sources (UMD, Under Monitor Display). This is a concept that is out of date, thanks to the technology of 3Way Solutions, which widens in a great form the range of applications of multiviewers, managing to attend much more applications than what could be achieved before with multiviewers. Following is a detailed description of the technical requisites desirables as standard for a multiviewer, and also a series of new functionalities that power up its capability to bring solution to several problems that are faced in broadcast applications.
In order to make a clearer understanding of the functionalities expected for a multiviewer, we divide them in 3 groups.
Current standard functionalities for a multiviewer
● Flexibility in formats for input signals. They must handle analog and digital video signals, SDI SD, HD, 4K, Transport Stream, ASI
● Flexibility for the signals configuration on screen. They must offer the capability to make available a flexible design of configurations, as well as memories of different configurations, which can be called in different productions.
● Present UMD of the signal sources for each image.
● Audio monitoring
● Alarm generation with sound
Functionalities that improve the performance of a multiviewer
● Capability to monitor different parameters of every incoming signal, with storage of event alarms.
● Audio monitoring with vu meters
● Capability to monitor loudness EBU-128
● Alarms for QoE QoS with standards like TR 101-290
● Streaming signal inputs via network with OTT (HLS, MPEG-DASH, RTMP) SRT
● Delivery of alarms by SNMP and/or email.
Functionalities that will increase even more the features, and widen the range of applications of a multiviewer
● Storage of incoming signals for later auditing
● Resend of the multiviewer screen to other destinations via stream IP
● Operation and monitoring 100% web to obtain a remote monitoring center operable from other sites
3Way technology allows to cover the 3 groups of functionalities, simplifying the installations of production centers of television and radio, with an integration focus much higher than what was known up to now.
