Due to these challenges,the basic performance requirementshave been identified asthe following: •Synchronicityofthevideo feeds.•Latency of VAR system video feeds: •Objective video quality assessment of the output of VARsystems. Following these basic performance requirements, the test methods described in this handbook include: 1.Measurement ofthesynchronicity of feeds by analysis ofthe content in the video feeds.2.Measurement ofthelatency of feeds by usinga sample video which is ingested through the VARsystem. 3.Testing andevaluation 3.1.Synchronicitytest VAR providers must be able to ensure that thecamerafeeds they are displaying to the VAR are insynchronisation. This is particularly important when checking offside situations as it is essential thatthe feed which captures the ball being played and the feed where the offside analysis is conducted, 3.1.1.Test setup The following equipment shall be used fortheassessment of synchronicity between video feeds: •A computer playing a4K quad-split video with pre-delayedquadrants.•A quad split device dividing the 4K quad-split into four parallel 1080pSDI video-streams.•Acomputer with a grabbing box to record the1080p SDI quad-split sent back to the test institute. 3.1.2.Methodology The test setup, illustrated inFigure2, consists of a sender transmitting four 1080p video signals thataredeliberately out of sync. TheVAR provideris required to re-synchronize these signalsandsend Prior to the start of the test, the VAR provider will be given a10-minute synchronization periodusingatest versionof the measurement signal. This test version contains the same four video feedsanddeliberateout of synch setup as the measurement version,except that it does not include the After this period,themeasurement versionof thevideosignalswill be transmitted for arecordingperiod of two min
