The broadcaster’s live-to-VOD workflow uses AWS Elemental Live video encoding technology to create a clean feed of broadcast content from an SDI source with SCTE 104 markers indicating program start and end time codes. Elemental Live decorates the HLS manifest with SCTE35 markers that it decodes from the SCTE 104 markers, and the feed is then written as HLS, an HTTP-based adaptive bitrate streaming communication protocol, to Amazon Simple Storage Service (Amazon S3). An AWS Lambda function parses the manifest and transfers segments between program start and end markers to another Amazon S3 bucket. Programs are then transcoded via AWS Elemental MediaConvert to deliver frame-accurate live-to-VOD assets.
Since moving to AWS, TV2 says it has also realized scalability, stability and flexibility improvements. “TV 2 is proud to deliver live and near-live content that brings us Danes together, and our technical teams and infrastructure play a big role in that. More than fifty percent of our customers are active users. But when a viewer misses the evening news or the start of a big sports match at 5pm and wants to catch a replay, they need to be able to catch up as soon as possible. AWS allows us to deliver near-instant access to live content for on-demand viewing,” explained TV2 Chief Technology Officer and Digital Officer Rahul Yadav.
“AWS offerings are extensive and provide a strong shoulder for our team to stand on,” “Our new infrastructure has helped our team establish a solid workflow and improve the viewer experience by enabling us to quickly turn around frame-accurate live content for on – requires viewing, so our subscribers don’t miss a thing. It also allows us to achieve our goal of becoming a tech hub for innovation where talented minds in technology can thrive.”
Generating VOD files previously took TV 2 up to three hours, and with AWS it can deliver them instantly. The infrastructure has also helped TV 2 accelerate the ingestion and transcoding of new content libraries for its VOD platform, while improving the overall quality of the content it distributes. “We are increasingly transcoding large amounts of content from libraries we acquire and increasing video quality,” Yadav added. “With AWS, we can make content available via VOD faster to improve the overall platform experience for subscribers.”
Going forward, TV 2 says it will continue to focus on improving the subscriber experience. The company is exploring how to expand the use of machine learning and the tools AWS provides to improve customized viewer profiles and real-time content recommendations.
