Broadpeak says it has completed unified packaging and encryption of DASH and HLS formats. Using the latest version of its BkS350 origin packager, Broadpeak delivered DASH and HLS video fragments using the same chunks (encrypted with CBCS) and container (CMAF) for both protocols, a capability intended to optimize storage costs for OTT service providers.
Until CMAF was developed, HLS and DASH needed to be delivered in different containers. In addition, Apple FairPlay and Google Widevine used different encryption schemes (i.e., CBCS and CTR), creating the need for a different chunk for each streaming format (i.e., HLS and DASH) even with the new CMAF container. Now that Widevine allows CBCS encryption, it is possible to encrypt one CMAF fragment for both HLS and DASH formats.
"Today, OTT delivery can be costly in terms of network bandwidth and storage due to the multiplication of streaming formats. Service providers need to deliver video content in two entirely different packaging formats and two different encryption schemes in order to reach all devices," said Jacques Le Mancq, CEO at Broadpeak. "The BkS350 origin packager eliminates these issues and unifies video delivery by introducing a common video streaming scheme for several players. We're excited to share this innovation with our customers and support them in the optimization of their overall video streaming costs."
Broadpeak's BkS350 origin packager creates only one chunk for both HLS and DASH streams. CMAF is used as the packaging container format and CBCS as the encryption scheme. The solution is intended to reduce CDN storage costs while simplifying the headend and requiring fewer packaging resources.
