How to watch F1 on TSN or RDS with friends in another province
One person on TSN in English, another on RDS in French, four time zones between them. One room and one shared picture.
Canada watches the same race in two languages and across four and a half time zones, which is the exact split a shared room is built for.
TSN and RDS
9 watching
CoViewer is a free extension made by BoxBoxd. It holds every picture on the same second and puts a chat beside the video. It never rebroadcasts anything, so each person watches on their own subscription.
The setup, six steps
Add CoViewer to Chrome
It is free and it takes one click from the Chrome Web Store. There is no account to create, no card, nothing to configure. The extension does nothing until a race is on your screen.
Open the race on the broadcast you already pay for
F1 TV, Canal+, Sky Sports, DAZN, ESPN, Viaplay, Apple TV, RTL, Kayo, Fox Sports, Sky Italia, NOW, WOW, YouTube or Twitch. Everyone in the room keeps their own subscription and their own commentary language. Nothing is ever rebroadcast.
Let it recognise the session
CoViewer reads the page title and the player to work out which Grand Prix and which session you opened. When it is sure, the launcher appears at the edge of the video. If you are watching something else, it stays quiet.
Create the room and copy the link
One click creates the party and gives you a short link. Send it in the group chat, by message or by mail. The room is yours, you are the host and playback follows you.
Your friends open the link
The link explains the two steps, adding the extension and opening their own broadcast. They join with the same code and appear in the room within seconds, wherever they are and whoever they watch with.
Watch the race together
The sidebar opens next to the video with the chat, the reactions, the live standings and the room. At the flag you rate the race and pick your driver of the day and it posts to your BoxBoxd profile.
The detail that counts here
Language is a per person setting here. The TSN commentary and the RDS commentary run side by side in the same party, because only the playback position travels between browsers.
How does the sync hold?
The host sends the playback position to the room every three seconds. Each viewer compares that position to their own player and corrects the difference quietly.
A gap under two seconds is closed by nudging the playback speed by five percent for a moment, so nobody sees a jump. Past two seconds the player seeks straight to the right place. On a live broadcast only play and pause travel, because a live stream carries its own clock.
Ad breaks are handled too. When one person hits an ad break, the room waits and resumes when everyone is back on the race. That single detail is what usually breaks a watch party built for films.
What time the races start across Canada
Canada watches the same race across four and a half hours of clock. The British Grand Prix starts at seven in the morning in Vancouver and at half past eleven in St John's, and the season opener in Australia falls on Saturday evening out west while it is already past midnight on Sunday in Newfoundland.
A group split between two coasts is the normal Canadian case rather than the exception, and it is the case a shared room is built for, since the host position travels between players instead of a start time.
