1. Update Analyzer and Receiver
Make sure Analyzer and Receiver are on the latest versions. Analyzer may prompt you to update when it opens. If it doesn't, go to Reference > Options and click Check Now. Updates are also available on the Fairplay website.
2. Match-day WhatsApp channels
| Channel | What it's for |
|---|---|
| Match ops groups | Created by each state. They carry the critical match-day information: team sheets, toss results and delays in play. If you need to be in a state's group and aren't, contact the home team's match operations team or a member of the CA Performance Data & Tech team. |
| Cricket 21 / coding hub groups | Put all coding requirements through one channel, so communication stays transparent. There's a group for each domestic competition, and for international men's and women's cricket (including A tours). |
As the home team analyst, you're responsible for the match-day coding. Confirm the coder at least 4 hours before the match. Cricket 21 coders can be up to 8 hours away in time zone, so for them it's best to get in touch the day before.
3. Pre-match shell setup
Import the match from the cloud
The CA Performance Data & Tech team sets up the match shell beforehand. Import the match txt file from the cloud into Analyzer and check that the match details are accurate, including the officials section.
Add the players
Add the players to the match txt file in Analyzer. Check that their jumper numbers are up to date and their playing status is P (playing). If you don't know the opposition players yet, add them when the team sheets arrive on match day.
After the toss
Enter the toss details and which teams are batting first and second on the Match tab.
4. Video sources
Set up and test your video source
Set up and turn on your video source as your venue or coding requirements need: for example, Frogbox, bar TV connections, IP cameras or Fulcrum. Then test it in Analyzer:
- Go to Reference > Video Capture.
- Under Pipeline (Media Foundation), choose your video converter or source from the Video Source drop-down.
- Click OK.
Test well before the first ball. If the source isn't working, troubleshoot by a process of elimination, and leave yourself enough time to fix it.
Streaming links
Remote coding, particularly, needs streaming links. These come through CA's Slack channel, which is the broadcast source external coders code from. If you don't have Slack access, ask a member of the CA Performance Data & Tech team.
Once you have access, copy the m3u8 video links and send them to the coders through the WhatsApp group. You can also open the footage in VLC if you need to.
5. Match information and outgoing feeds
Match information
Once the coder has the match set up, they need a few more details before play starts, so the data is as accurate as possible:
| Detail | Where it comes from / why it matters |
|---|---|
| Pitch number and boundary dimensions | Match ops or the curators can give you the pitch number (counted left to right) and the boundary dimensions for the match. |
| Striker end (north / south) | Lets data be collected by end. |
| Umpire ends | Which umpire is at the bowler's end, so umpires can be tracked through the match. |
Outgoing feeds and Receiver
Once setup is complete and the coder is on the coding screen, they can set up the outgoing feeds for analysts, coaches and match referees through View > Outgoing Data Feed.
Downstream users (analysts, coaches and match referees) check the feed in a separate application, Receiver. It has a similar setup, but with an Incoming Data Feed: connect to it and select the correct match feed.
6. In-game coding remediation
Keep track of coding accuracy during the match, so there's less to correct afterwards. If you notice anything wrong, tell Cricket 21 straight away through the WhatsApp group.
7. Post-match checks
Get the latest version of the match
- Import the coder's final match txt file, from the cloud or from the WhatsApp group, so you have any last-minute edits from Cricket 21.
- Close Receiver.
Check player status
Check that every player listed under each team has the correct playing status. Right-click the status cell to change it.
Complete the health check
Review the health check report in Matches > Health Check Coding, and clear or suppress (right-click the row) every entry listed.
Housekeeping
- Check the scorecard (Reporting > Match > Scorecard) against a reputable cricket website, and correct any differences in scores, player statistics or match details.
- On the Options tab, click Update Deliveries so the deliveries line up with the powerplay structure.
- Complete the pitch number, block and venue dimensions on the Options tab.
- Check the Result tab is correct for each innings and fix anything that isn't. Cricket 21 completes this as part of their post-match workflow.
- Update any external IDs (where available) on the External Ids tab, by running the ball-tracking and Opta overlays in Analyzer and adding the Cricinfo ID from the match page URL. Run the overlays even if you've run them before: third-party providers sometimes update their details after a match.
8. Final export and transfer
- Once the checks above are done, change the coding status to Final.
- Run the missing clips utility (from Match or Reference > Utilities) to flag any video clips missing from the match txt file.
- When you're satisfied everything is correct, export the match txt file through Match > Export Data > To Cloud.
- If the vision has changed, transfer it to the blob storage container.
Where to go next
- Role of the Coder & Role of the Reviewer: who does what on match day.
- Match Setup: each tab of the match setup and what to check.
- Incoming and Outgoing Feeds: connecting Analyzer and Receiver to live data.
