PREMIUM VIDEO DELIVERY

Erstream has been operating globally for the past 14 years as a leading technology company with a strong presence in the world’s leading markets providing top-quality products and solutions to content owners and broadcasters. Their products include encoding, CDN and web streaming software and services that are researched and developed in their own R&D labs under the expert supervision of uniquely gifted engineers. Erstream works in collaboration with Turkey and the international market’s established content creators and broadcasters.

Erstream focuses on end-to-end online video delivery and works continuously to improve cost-effective solutions to their customers. Erstream CDN Special Features Compared to other CDN services available in the market, Erstream is only focused on premium video delivery. Features include the following: • Storage cost of the customer brought down by 70-80%. • Increases performance of storage and origin dramatically. • Provides a high performance Edge server that does not require a specific

HW; and a very powerful cache layer with enhanced features, and a cost effective proposal.

As many other traditional E2E CDNs, Erstream’s operational flow is as below;

Ingest Work Flow (VMS) • Encoding VOD and LIVE. • Multi DRM. • Common Encryption. • Number of chunks reduction of HLS files. • Upload, callback notification. • Multi CDN support. • Thumbnail, logo, watermark insertion, etc. • API.

Storage & Origin • Based on Gluster File System. • Similar Topology Netflix. • Built-in origin, zero network delay between storage and origin. Storage and origin server are built by Erstream based on an open source SW. • Arc Cache file system with custom settings according to last miles

behaviour and content type (MP4, HLS, SMOOTH STREAMING, JPEG, HTML, CSS, etc). • Multi Nodes. • 10Gbps constant uplink for chunked content. • Multi-Format Support (mpeg-dash, HLS, Smooth Streaming). • Multi DRM Support. • On the fly DRM support. • Custom Firewall settings for DDOS or SYN(when server serves directly to last mile).

Cache • Customised for premium video delivery only. • Enhance caching algorithms. • Enhance fingerprinting techniques to prevent re-broadcast of any important event especially sports. • Custom Edge service.

Analysis • Based on no-SQL DB. • Flexible filtering based on any different dimension in server logs.

Encoding Service Erstream Encoder / Encoding Service supports H264 and HEVC as codec; HLS, Smooth Streaming and Mpeg-Dash as video format. So how is the Erstream Encoder different from other encoders? The Erstream Encoder makes a pre-calculation before the encoding process starts. This calculation finds out the ideal maximum bitrate for a specific content. The ideal bitrate is often determined by operators. Most operators want to give the best picture quality to their viewers and the easiest way to achieve that is by increasing the size of the bitrates of the outputs. However this usually causes other issues and does not increase picture quality as expected.

To achieve picture quality, there are two criteria to be observed. One, if the size of the bitrate is lower than it should be, then you lose quality. And vice versa – which is if the size of the bitrate is higher than it should be, then there is the loss of storage size and storage performance (especially for standard HLS format, wherin storage is important as each HLS folder consists of thousands of mini ts files). There is also capacity demands in terms of CDN Edges or Uplink and unwanted re-buffer issues at the last mile because of high size bitrates, or low bitrate viewing ratio as it is difficult for client devices to download high-sized chunks. As a result of these blocks in bitrate determination, Erstream developed a workable logic that would help decipher it. In 2011, they created pre-calculation for deciding the ideal maximum bitrate size for a specific content. The ideal bit rate size is the bit rate size above the picture quality that does not increase and below the point where the picture quality can get worse.
