As broadcasters and content providers widen the reach of supported devices and platforms, multiple streaming formats are required. Inserting dynamic content, often targeted ads, is relatively straightforward for HLS and multi-Period DASH and there are a number of providers who can offer this. Enabling the broadest reach requires solving the problem for the large install base of legacy devices that only support Smooth Streaming or single Period DASH. Targeted ad insertion services (DAI’s) or regional playout suites can be expensive for delivering regionalised live streams particularly when the regionalised content is promos and or opts. It is possible to regionalise in the streaming domain without adding playout suites or using DAI. You can even generate compliance recordings. In this session, we will walk through how we successfully delivered dynamic content insertion for regionalisation purposes into HLS, DASH and Smooth Streaming live streams from a single global playout source and with a single encode. We’ll share the highlights of our journey, including: -The technical requirements for the source streams and the encoder output -How signalling must be configured and inserted using SCTE-35 messages, and how it is included in the encoder output -The custom changes made within the packaging layer for each of HLS, DASH and Smooth Streaming to dynamically insert alternate content based on SCTE-35 -The functional constraints that stakeholders need to buy in to to make this approach viable -The preparation and conditioning requirements / workflow for the insertable VOD content -Suppress / forward markers to allow downstream layering of DAI opportunities on top of the regionalised output -How to ensure QoE and how monitoring is addressed -The challenges we overcame en-route to production deployment -The complexities to future features / changes that have derived from the solution -How the next generation implementation moves the insertion from the packaging domain to the encoding domain, which challenges it solves, and which new challenges are introduced.
