THRON Player: accessibility, interface, and templates – THRON Guide

Player v1.2 is the new version of the THRON Player: faster, fully accessible (WCAG) and with a revamped interface for audio and documents. For most users no action is required — the Player updates automatically. This article explains what changes, where and for whom.

What changes with v1.2

The main news concern three areas: accessibility, interface and technical libraries.

Area	News
Accessibility	Full keyboard navigation, screen reader support, alt text visible in the player
Audio player	New graphic interface (wavesurfer.js removed)
Document player	New interface + zoom, text search, fullscreen mode, keyboard shortcuts
Images and galleries	Zoom and pan with custom implementation; pinch-zoom support on mobile
Video/audio/image galleries	Navigation with Swiper.js

Where it updates and where not

Not all areas of the platform automatically upgrade to v1.2. Check the situation for your workspace.

Area	Active version	Required action
Digital Assets (dashboard)	v1.2 automatically	None
CEM — new templates	v1.2 (CE2 template)	Create a new template selecting CE2
CEM — existing templates	v1.1.x (CE1 template)	None — they remain on v1.1.x
Generated embeds	v1.1.58 if ≤ 1.1.57, otherwise unchanged	None — the version is locked
Products section	v1.1.58 (technical limitation)	None — update coming soon
Asset Workflow	v1.1.x temporarily	None — update coming soon
Product Workflow	v1.1.x (maintained)	None

Warning: CE1 and CE2 templates are not interchangeable. A template created for v1.1.x does not work correctly on v1.2, and vice versa. Do not attempt to manually convert existing templates.

How to create an accessible template in the CEM

If you want to use Player v1.2 with your embeds and deliveries, you must create a new template based on CE2.

Log in to the CEM (Experience Manager)
Click on New template
Choose the Customer Experience Template 2 (CE2) base template
Customize and save

The existing CE1 templates remain active and continue to receive updates within the v1.1.x branch. You don't need to migrate them unless you have specific accessibility needs.

Activate the accessible Player on your client_id

To enable Player v1.2 on a specific client_id, a configuration on the Admin side is required.

If the client_id DOES NOT have the CEM:

Log in to View Platform
Find the client_id to configure
In the User Properties, add the value ACCESSIBLE_PLAYER

If the client_id HAS the CEM:

Log in to Admin Console → Settings by tenant → CEM
Enable the CEM for the client_id

Note for Admins: The ACCESSIBLE_PLAYER configuration is per client_id. Each client_id must be configured individually if it doesn't use the CEM.

Keyboard shortcuts — Document player

The v1.2 document player introduces full keyboard navigation. Keep it handy.

Zoom and view

Shortcut	Action
`Ctrl/Cmd` + `+` or `Ctrl/Cmd` + `=`	Zoom in
`Ctrl/Cmd` + `-`	Zoom out
`Ctrl/Cmd` + `0`	Reset normal zoom
`Ctrl/Cmd` + `Alt/Option` + `p`	Activate fullscreen mode
`h`	Activate the hand tool
`s`	Activate the text selection tool

Navigation and search

Shortcut	Action
`Ctrl/Cmd` + `Alt/Option` + `g`	Go to page
`Ctrl/Cmd` + `f`	Search text in document
`Ctrl/Cmd` + `g`	Next occurrence
`Shift` + `Ctrl/Cmd` + `g`	Previous occurrence

Sidebar and outline

Shortcut	Action
`F4`	Show/hide the sidebar
Click on Show document outline	Show the PDF outline (if available)
Click on the triangle next to an item	Expand/collapse nested items
`Shift` + click on the triangle	Expand/collapse all child items
Double click on Show document outline	Expand/collapse all items

Technical appendix — Changes to embed libraries

This section is intended for technical teams managing custom templates or embeds with custom CSS/JS.

The transition to v1.2 involved the removal and replacement of some libraries. If you have customizations based on these libraries, a code review is required.

Player	Removed library	Added library	Impact
All	`jQuery`	—	Complete JS review in custom templates
Images and image galleries	`PanZoom.js`	Custom implementation + `pinch-zoom-js` (mobile)	JS and CSS review
Audio and audio galleries	`wavesurfer.js`	—	JS and CSS review
Image galleries, videos, video gallery, audio	—	`Swiper.js`	JS and CSS review

Warning: If you have templates with custom CSS or JavaScript based on jQuery, PanZoom.js or wavesurfer.js, these will not work correctly with Player v1.2. Before migrating to CE2, plan to review your custom code.

Embed update logic:

Embeds with version ≤ v1.1.57 → automatically updated to v1.1.58
Embeds with version v1.1.58 → no automatic update
Embeds that explicitly choose v1.2 → use the new CE2 template

For systems that update automatically (e.g., Digital Assets dashboard): no action required, except for the presence of custom CSS/JS.
