Delivery format: URL.
If you wish to deliver dynamic material (HTML/HTML5 material), please take this into consideration:
Browser version and resolution
- Browser: Chromium version 59. The campaign should be produced within the limits of functionality of Chromium version 59.
- Please note that we cannot guarantee functionality if other Chromium versions are used.
- The connection is via 4G. In order to make sure that the connection is enough (e.g for streaming) we always need to try the material on selected places where the campaign will run.
- Resolution: 1920×1080, 1260×720, 1024×576, 640×352, 568×320, 568x320px and 1440×810. Please check the bought areas.
A dynamic HTML campaign should consume an average of 0,5 MB per displayed slot over a 24 hour period. If this consumption is exceeded, Clear Channel reserves the right to paus the campaign.
Tips to reduce your data usage for your campaign are:
- Refrain from using cache busters
- Compress media files
- Add http headers for Cache-Control: public, max-age=31536000
- Let service workers manage traffic (e.g. workbox with cache only strategy & use Cache API to add media to the cache)
- Serve media without ranges, http headers: Accept-Ranges: none
