Yesterday, I had the pleasure to co-present with Melika Golkaram of Google and Moore Macauley from Harmonic on “Building a next generation streaming platform with Sky”.
Melika reminds us that streaming is a new industry and provides insight into YouTube and how our viewing habits have changed since it’s launch in 2005. One amazing statistic is that we’re now consuming one billion hours of content per day and explains how Google are making the necessary investments to meet the needs of media companies.
I explain (15:25) the technical and business benefits of moving live sports workloads to the cloud and introduce our Software Defined Streaming platform, which is designed for highly available live streaming. We call this concept the Single Channel Fault Domain, where we run a synchronised live channel across two data centres and demonstrate how the system can self-heal without impacting customer viewing.
Moore explains (40:52) how Harmonic collaborated with Sky and Google to solve several difficult engineering challenges and demonstrates a live channel running in google cloud.
17th April Update: Slides are now available.
I’m very grateful to have been asked to speak on two panels at the Streaming Forum conference in London, ExCel on the 26th February, where we’ll be discussing “OTT: Better than broadcast?” And “OTT moves towards microservices”.
The conference programme is available here and here’s a sample of topics below. Hope to see some of you there
I’m very grateful to have been asked to speak on a panel at the TV Connect conference in London, Olympia on the 9th May, where I will be discussing “The Great Codec War”. The conference programme is available here and here’s a sample of topics below. Hope to see some of you there 🙂
To follow up my previous series of five articles on the important elements of a live streaming service, I created an internal training course for Sky staff covering; transcoding, packaging, encrypt, origin/CDNs and video quality.
I wanted to explore new ways of bringing training to life and created an annotated online presentation of Content Delivery Networks using the excellent prezi.com site. I hope you find it informative.
One key observation is that “You cannot manage, what you cannot measure” and having insight into the video player behaviour is essential to optimise the viewing experience.
I was invited to present a joint case study by Sky and Conviva at the Future of Broadcasting conference in London. Where we describe how we saved up to 4,500 streaming sessions by automatically detecting and moving them to another CDN with our CDN selector capability.
For example, if a customer is unable to sustain a consistent 5Mbps throughput on their home broadband connection, the player will automatically step down to a lower bitrate and sometimes also to a lower screen resolution.
We take our customers streaming quality of experience very seriously and have four key streaming performance indicators that we constantly monitor.
- Buffering Ratio of under 0.4% per hour.
- Average Bitrate.
- Video Start Failure.
- Exit Before Video Start.

I’d like to thank Ed and Lindsey at Conviva for their assistance.
