HAVING YOUR LIVE STREAM AND TIME-SHIFTING IT TOO By KEN HAREN | SOLUTIONS ENGINEERING MANAGER, TELESTREAM Live programming continues to drive viewership and audience engagement, making it especially attractive to advertisers and direct marketers looking to attract followers. At the same time, audiences are moving to a wider gamut of viewing platforms, which offer an increasing number of ways to time-shift the viewing experience for their con- venience. Ensuring that programming is available and optimized for each potential “viewing window” at the highest quality, while also preserving rights agreements, is paramount for a modern broadcaster or content owner. Live Window Whether delivering live linear programming, or producing live events to an OTT platform, the first opportunity for the audience to engage with content is in the live viewing window. In addi- tion to producing a high-quality live stream that works across devices and platforms, today’s con- tent programmers must develop sophisticated delivery strategies for managing an Internet-scale live viewing audience. Their operations need to address advertising workflow, subscriber manage- ment, digital rights policy and frequently-chang- ing brand marketing initiatives. Programmers are continuing to leverage social media as a live second screen to entice audiences to premium shows and increase audience engagement, and want to synchronize the audience experience as tightly as possible across the broadcast, OTT and social domains. Today’s live video solutions can no longer regard each destination endpoint as a complete channel. Originating channels today commonly include a mix of multiple live stream origin endpoints to 54 • Broadcast Beat Magazine • support live redundancy and content distribution network (CDN) load balancing. This is required to mitigate the “hug” of the Internet for programs that garner large audiences. Additional delivery endpoints to social media destinations for some or all of the premium content experience must also be a component of the live channel. Lastly, a live video cache and professional video archive recording are critical to executing sophisticated live-to-VOD workflows. It’s not uncommon for a single live channel today to consist of several MPEG DASH, HLS and RTMP payloads delivered to multiple destinations, while also capturing an archive record of the source into a professional production format such as ProRes. Just-in-time packaging (JITP) techniques also help to miti- gate the number of package formats that must be hosted within the live stream channel origin, enabling JITP encryption and conversion to facili- tate an efficient storage and delivery strategy, reducing complexity and costs.
