Cloud Video on Demand (“VOD”) content End Subscriber

Fundamental points of cloud VOD delivery Higher quality more bits (higher resolution, lower

compression) Actual throughput from SERVER subscriber changes

dramatically from subscriber to subscriber and time of day due to changing micro and macro Internet conditions

Content Delivery

Chris Newton

Download (Progressive Download) Streaming

Delivery Methods

Chris Newton

Essentially same as downloading any file from a Web server

Progressive can start playing file as soon as a portion is downloaded without waiting for entire file

DEMO

Download Delivery

Chris Newton

Pros Can delivery a higher quality file Once loaded, subscriber can play over and over

again without being connected Cons

Security – once file on HD, can be copied Advertising Ability to delete Cannot jump ahead to parts not downloaded

Download Delivery, cont.

Chris Newton

Parts of file are delivered as small chunks (e.g. 2 seconds in length) from a special Streaming Server

Streaming Server receives commands from Application/Player to tell it what “chunks” to send

DEMO (single stream)

Streaming Delivery

Chris Newton

Pros Better overall security as content never

stored on local storage Easier to put in targeted Advertisements

Cons Must encode multiple streams to deal with

changing Internet conditions Requires special delivery formats

Streaming Delivery, cont.

Chris Newton

Microsoft Silverlight Adobe Flash over HTTP Apple HTTP Live Streaming (HLS) Widevine Proprietary

All operate in a similar, but PROPRIETARY fashion: Chunks delivered to player over HTTP

RSTP, RTMP all older formats

Common Streaming Formats

Chris Newton

Base Assumption for online TVE is that a subscriber would rather keep watching a program at a lower quality than “wait” while show “buffers”

This is done by adjusting the QUALITY (resolution/bit rate) automatically based on CURRENT SUBSCRIBER INTERNET conditions

Demo: ABR

Adaptive Bit Rate (ABR)

Chris Newton

Motion Pictures Expert Group – Dynamic Adaptive Streaming over HTTP Essentially a set of common tools (similar to

MPEG-2, MPEG-4) to allow for NON-PROPIETARY encoding, encryption, decryption and playback of content

Widevine (Google) one of first to announce a full MPEG-DASH compliant product (June/July 2014 release) for both VOD and LIVE content

Future MPEG-DASH
