SMT-VAR

SMT-VAR is a configurable video replay system built specifically on FIFA’s foundational requirements of video latency, quality and synchronicity.

​

Utilizing input and feedback from experienced operators and industry professionals, SMT-VAR allows referees and operators to review any moment quickly, efficiently and accurately from every camera angle. In addition, SMT-VAR combines the FIFA-certified SMT-VOL solution into one product, so operators can easily toggle between video review and offside decisions from a single interface.

 

Since 2021, SMT-VAR has been a FIFA-certified Video Assistant Referee system. Additionally, SMT is excited to be a member of the FIFA Quality Programme Technical Advisory Group for VAR and looks forward to the opportunity to continue evolving the future of technology in football.

TANDEM

A simultaneous playback and record video server, SMT-Tandem functions as the engine that drives all video in SMT-VAR. All incoming video sources route through SMT-Tandem for processing before outputting the video to client machines.

​

SMT-Tandem machines can be configured to handle up to (16) 1080i50 inputs on a single video server. A single machine can be configured to handle physical SDI and/or Internet Protocol (IP) cameras sources. SMT-Tandem supports a variety of video input formats, including but not limited to interlaced, progressive, super slo-mo and IP.

​

SMT-Tandem’s user interface provides a variety of system status checks, configuration options, and monitoring information so that users can confirm the video flow is operating as intended. All inputs are recorded and stored locally on the system for post-event accessibility.

SMT-Tandem utilizes “channels” as a destination directory for recording inputs. Each input maps to a channel for recording. The output is loaded from each channel and continuously chases live video.

 

The output video to client machines can have a configurable delay adhering to specific protocols and has the flexibility to output as SDI or streaming video. Streaming the video between video server and client machine(s) allows greater flexibility for supporting other client applications using the same video server(s).

KALEIDOSCOPE

SMT-Kaleidoscope is the front-end, video tile display that combines all video outputs from SMT-Tandem(s) and makes each video source available to view simultaneously in a tiled mosaic. In a VAR system, the Replay Operator will run an instance of the application and be able to quickly toggle between VAR and VOL modes as well as publish tiles to the VAR Monitor, Referee Revision Area (RRA) and Host Broadcaster (HB) for reviewing.​

KScope - Incident List.PNG

INCIDENTS TAB

Growing list of bookmarked timecodes for quick recall of potential reviews with editable incident names and color coded based on which user role marked each Incident.

Operator controls in SMT-Kaleidoscope are available through a library of hotkeys and/or controller:

Playback Controls

  • Play/Pause

  • Jog/Shuttle at variety of speeds

  • Frame-by-frame video stepping

  • Video looping

  • Single-button go-to-live retrieves latest video during live event

  • Paired with the JLCooper Slo-Mo Elite controller, a professional-grade replay device, for expanded playback controls including a speed adjust T-bar

​

Configurable Layouts

  • Preset standard layouts for a variety of sources

  • Layouts can be selected from preset list (2x2, 3x3, 4x4, etc.)

  • Custom layouts can be built and saved for easy recall based on operator preferences

​

Tile Zooming

  • Allows closer look at the action

  • Zoom percentage indicator

  • Reset button quickly restores the tiles back to default state

  • VAR touchscreen allows pinch to zoom, double tap to publish, and general touch events

Incident Marking

  • Single-button marking of potential reviewable incidents during a match

  • Build an organized library of incidents, easily accessible through the Incident List module

  • Each incident gets assigned a starting timecode; operators can mark an end timecode and loop during review

  • Incident list color-coded by user role to quickly determine if incident marked by the RO, VAR or AVAR

  • Assign an incident type (goal, red card, yellow card, offside) to marked incidents for additional filter parameters

  • Incident List grows indefinitely as event progresses, sorting by most recent

  • Incidents can be manually renamed and dynamically deleted if deemed not critical

  • All incident information saved to OASIS and searchable for auditing and analysis 

​

Custom Input Labels

  • Every input assigned a label

  • Operators can rename labels

OASIS

INPUTS TAB

List of video inputs used to dynamically rename and indicate whether input is SMT-VOL enabled

LAYOUTS TAB

Preset list of standard video tile layout options and user created custom video tile layouts

VOL TAB

Configuration settings that help to determine offside decisions

OASIS

SMT’s 38 years of experience has led to the creation of a powerful organizing philosophy called OASIS and a powerful data and video management system called the OASIS Platform (Organization of Asynchronous Sports Information Subsystems).

 

OASIS as an organizing philosophy views the data landscape of a sports league in three layers:

 

Level 0       All subsystems that create data or video

​

Level 1       The central hub that absorbs, collates, synchronizes, organizes, expands, and

distributes all Level 1 data via push and query APIs

​

Level 2       All subsystems that consume, present, or use the data

 

As a product, the OASIS Platform is a highly integrated, multi-venue, time-synchronized, multilevel, data/video management system that SMT architected, designed and created to provide professional sports leagues with a centrally controlled and league-controlled platform to organize, maintain, administer, and manage all phases of the league’s data creation, data distribution, data visualization, and data monetization.

 

Using SMT defined protocols, SMT-VAR utilizes OASIS for user management, organization of events & sessionIDs, reviewing incident playlists and exporting of post-event clips, all within a web app dashboard called SMT-VAR Manager. This online dashboard makes it easy for league administrators to monitor the status of events and protocols. The export tool allows users to export incidents in a variety of formats, including all available cameras, configurable destination paths and the addition of pre/post roll time to each exported clip.

 

Additionally, OASIS is fundamental to the integration and organization of player-tracking data to use in SMT-VOL mode.
