Organizations and broadcasters looking to increase the end user experience can benefit from the recent advancement of 4K streaming video capabilities at IBM Cloud Video.
This technology is available for both external and internal use cases. This means it works for unsecured, easily available marketing video content. It can also be used, though, to deliver 4K streaming video for secure, internal video as well. Secured video can be presented through integrations with a corporate directory via Single Sign-On (SSO).
Specification wise, the term 4K refers to the image resolution. It is typically over 4,000 pixels in terms of width of the image, which is where the name comes from. However, the image can be smaller, for example “Ultra HD” (UHD) is actually 3,840 pixels in width. IBM Cloud Video actually recommend using the 3,840 pixel, UHD version when broadcasting. However, content owners can use the higher resolution specs.
In terms of the end user experience, the 4K option can be selected from the video player. This player can be embedded on websites or shared as part of a company branded video portal. Unfortunately, many viewers don’t have the appropriate connection speed to watch high definition content, let alone ultra-high definition video. Thankfully, IBM Cloud Video has a QoS (quality of service) element inside the player. This uses a combination of adaptive streaming bitrates and multi-CDNs (Content Delivery Networks) to give the end viewer an optimal experience. This is done through detecting their connection speed and past performance, including buffering, to give them an appropriate bitrate and resolution combination along with using an optimal CDN.
The ability to broadcast in 4K is available over the platform now. Before streaming at this resolution, though, broadcasters need to reach out to IBM Cloud Video’s customer success to discuss their setup.
