What is Live
Streaming? Live Streaming is the ability for you to send a video signal, in real time, to your viewers. For example: As a Brightcove publisher, I want to stream my events Live! As a Brightcove publisher, I want to have a Live, 24/7 Internet Video Stream. 4 | Confidential © 2013 Brightcove Inc.
5.
Steps to stream
live 1 You must have some type of video source, this can be either live video or pre-recorded content. 2 You must have some type of encoder, either software based or hardware based. 3 You must have an entry-point and an exit point on a CDN. 4 You must have a player which plays the stream appropriate to the device. 5 | Confidential © 2013 Brightcove Inc.

Encoding Options
12.
Options for live
streaming • Software Only Encoding On Site – This is great for low budget productions, and has the ability to deliver a live stream to almost any Flash Enabled device. • Software Encoding On Site with In-Cloud Transcoding – This is perfect for sites with poor connectivity, or low cost solutions that require delivery to all devices. • Hardware Encoding On Site – Are essential for a mission critical live event, with high quality, high availability bandwidth and a large production. © 2013 Brightcove Inc.
13.
What do you
send? • You have many options for encoding live streams. How do you decide which are right? – Best Practices; Understand the various devices and their native screen sizes you plan to deliver to. • Estimate the bandwidth available for your target audience. • Evaluate the size of the player as it will be displayed on the web page. • In most cases, a top rendition of 1280x720p feed, at about 2 – 2.5 Mbps will very high quality. • Test and confirm the bandwidth available to you on site. • Review budgets to understand if limiting the streaming options will be required to stay on budget for • bandwidth consumption by users. • Choose up to 10 renditions from the following list and modify their sizing to match your player and device displays; 13 | Confidential © 2013 Brightcove Inc.

Connectivity & CDN Confidential
15 |
16.
The Internet •
What’s Required? – A high speed, high quality, rock solid connection. Most hardware encoders will need at least a 10 Mbps “up” pipe available for them, to stream 6-10 renditions. • What if that’s not available? – Then you should consider using an in-cloud transcoding service, like Zencoder. This allows you to send up a 2 Mbps 720p rendition (best practice) and receiving multiple renditions and multiple formats, delivered to all devices. • What if that’s not available either? – You can try to send a smaller, and lower quality signal up to the cloud for transcoding. Some customers have reported descent results by sending a 500kbps 640x360, and having it transcoded to all devices. • Wi-Fi? LTE? 4G? – While these technologies are becoming more and more common, their connectivity is still spotty, and ultimately, they may not be able to sustain a single, solid stream. However, there are ways to leverage several of these together, to get a solid connection. © 2013 Brightcove Inc.
17.
CDN •
To stream your live event, you’ll need a Content Delivery Network to deliver the resulting live stream. – Some key items to considers; The number of Points of Presence in your target region or, the world • The ability to deliver live stream HLS segments (HTTP Live Streaming Protocol) • The capacity to support a large amount of concurrent viewers • The availability of DVR for your live stream • Various security options for Live Streams (i.e.: HLSe AES-128, SWF+V, RTMPe, TTL, etc) • 17 | Confidential © 2013 Brightcove Inc.

Players Confidential 18

19.
Playing back your
live stream, to your viewers • Ultimately, after you’ve created all of your renditions for your live stream, you still have to deliver them to the end user in a way in which their device can ingest it, and offer a manual or automated option to switch between these renditions, based on screen size, connectivity and CPU Utilization. – For example, the Brightcove Player loads, and performs the following checks; • Detects user agent, and loads in Flash or HTML5, based on device capability. • Receives rendition list, and has the ability to move between the renditions based on needs. • Evaluates the display size and CPU utilization to ensure a smooth playback experience. • You will also want to ensure that the player has the ability to monetize your content, based on your needs. – Advertising Delivery to all platforms – Paywall options for all platforms – App Compatibility for App Delivered content © 2013 Brightcove Inc.

21.
To get started •
Here is what you need to get started – An Entry Point – A Username and Password for that Entry Point – Rendition List – A Stream Name (or Names, based on your Rendition List) • This, you make up, but may need to formulate based on requirements (event_angle_bitrate@epcode) – An Exit Point – Adobe Flash Media Live Encoder or Wirecast (for our demo purposes) – A Brightcove Account (for CDN info and Player Playback) – Zencoder (optional, but for delivery to all devices) © 2013 Brightcove Inc.
