Broadpeak says it has completed the world’s first unified packaging and encryption of DASH and HLS formats. Using the latest version of its BkS350 origin packager, the company, which provides CDN solutions and pioneered the development of multicast ABR, successfully delivered DASH and HLS video fragments using the same chunks (encrypted with CBCS) and container (CMAF) for both protocols. “This is a unique capability that will optimise storage costs for OTT service providers,” the vendor declares.
“Until CMAF was developed, HLS and DASH needed to be delivered in different containers,” Broadpeak points out. “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.”
Broadpeak says its BkS350 origin packager is the first solution to offer this capability. The company’s CEO, Jacques Le Mancq, comments: “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. The BkS350 origin packager eliminates these issues and unifies video delivery by introducing a common video streaming scheme for several players.”
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. This powerful new solution reduces CDN storage costs while simplifying the headend and requiring fewer packaging resources.
