Considerations for Carousel using 4K

December 18, 2018

Carousel 7.4 introduces 4K support for Brightsign series 4 players. Along with that, there are just a few things to consider. 4K content comes along with larger file sized. This has implications in two different areas. The SD card in your Brightsign player and the storage capacity of your Carousel server. Using larger HD video files runs the risk of filling up drives and SD cards which will cause issues with your Carousel system. Also, since the file sizes are larger, if your network bandwidth is on the slower side, the content you schedule may take just a little while longer to cache and display on the player. For example, if you were to create a full screen video alert, it may take a few minutes to get to the player and begin showing on the display. On the flip side of that coin, you will want to make sure that the resolution of the content you are displaying on a 4K channel is as close to the same dimensions of the zone as possible. If one were to upload a 1920X1080 image or video to a full 3840 × 2160 single zone channel, Carousel will automatically scale it up and the content would look less than ideal on the 4K display. Finally, if you are uploading larger files, you may need to adjust the default file upload size limit in IIS on the server. By default it is set to 2GB but it can be increased by following the instructions in this article.
