Web-based IPTV Brokering Service Models
and Scenarios
The key roles of the Brokering Service Provider are
(i) aggregating and managing contents or information on
contents from several original service providers
(ii) converting and optimizing the formats or codecs of
contents or information on contents

Make rich media management easy
canssManage offers a variety of products and services for effectively publishing your rich media for broadband and mobile
canssManage(Content Syndication)
Aggregation Service offers multiple easy-to-use tools for programmatically (or manually) uploading your media content into
canss using Watch Folders and Feed Readers by offering a reliable and versatile suite of tools for getting your media into our system.
Service Management Console provides a smart interface for managing your media. Ingest content, enter metadata, apply business
policies, and publish your media
Rule based Content Mediation converts your video into the media formats you need. Hosted by canss, transcodes can be
completed by our shared farm or on dedicated boxes
Profit Model Implementation helps you maximize your broadband video’s earning potential with effective ways to distribute it to the
right audience, connect it with quality advertising, and let viewers promote your video to their social networks.

QoS/QoE
QoE has became an important factor Video services through Internet has expanded not through broadcast network
E.g: Hulu, NetFlix, Youtube
Definition of QoE The overall acceptability of an application or service, as perceived subjectively by end-user (ITU-T
P.10/G.100)

QoE Measurement
Media Layer Model FR/RR/NR Model
Uses decoded media (audio/video) signal Measures video MOS (except audio MOS)
Related Staple Recommendations J.144 : 4 algorithms of FR (full reference) Model – SDTV
