2 stve (Pronounced Stevie ) Synchronized Television Ecosystem What is stve? Set of protocols to allow a display renderer, such as a TV, to participate in a synchronized orchestration of multiple content that is delivered to the renderer in different paths. P2

3 Motivation itv lacks a Production/Distribution Ecosystem Video itv Author? Edit? Distribute? Consume P3

4 The stve Ecosystem Content Identification Production & Operational Tools Skills needed: - UI design for non-technical personnel - Knowledge of various production workflows Distribution Skills needed: - Syndication logic for targeting multiple types of devices - Integrations with other core programmer technology Responses and Special features Skills needed: - Response server: Ability to process 100,000s transactions/sec - Feature Server: Specialized knowledge for specific event (fantasy football, judging apps, etc) Skills needed: - Fingerprint / Watermark / Signaling content identification - Maintaining massively growing database of available content - Servicing 100,000s transactions per second Applications Skills needed: - UI/UX Design for viewer interactions - HTML5, CSS, Javascript, other native device app technologies P4

5 IP layer and Semantic Standard Proliferation of IP connected devices that use HTML, CSS, Javascript for creating applications Can use these technologies as a base for building a semantic layer on top By defining a timeline object from which other event objects are hung, interactive applications can focus on user experience and less on basic data representations The device/application is responsible for identifying the content being watched (ACR, sync-to-broadcast, etc). The application then marries objects on timeline to current temporal location. For HTML applications, only a basic CSS reskin would be necessary to change the look and feel Other non-html platforms could use these protocols as well, as the data objects don t explicitly define the presentation layer and would provide the hooks necessary to invoke their own methods for applying styles P5

6 SmartTV ACR Application Usecase P6

7 Mobile/Tablet Application Usecase P7

8 Benefits of stve Recap Allows vendors to play to their strengths and helps open ecosystem up to become more mainstream Allows Application creators to start with a framework for how data will be represented Allows programmers to plug in new functionalities without replacing or replicating the entire system Allows interactive content to follow video content into syndication for reruns and International audiences P8

9 Future Work Compile lessons learned from first prototypes developed Further detailing in Browser-Server environment needed W3C would be ideal place to develop these standards for browsers and the Multimodal Applications that sit on top of them. P9

14 stve Protocols and Standards Synchronous Content Protocol Specify Communication Layer and Interactive Content Templates JSON-Based Abstract communication layer, and focus on how to request and receive synchronous content One Client, using Web technologies (HTML, Javascript, CSS) for browser based apps Utilizing any backend system that adheres to the spec Alternate content for different display devices Tablet, Smartphone, Laptop/Desktop, Connected TV, IP Connected Devices Style classes provided to link to CSS or other method of applying style (native platforms) Content Types: Poll, Trivia, Fun Fact, Chat, Data Table, Listing (headlines), E-Commerce, Video, Audio, Ad Unit, Link, Clear, Others P14

15 stve Protocols and Standards Timeline Data Structure Discreet Cues Can have multiple display resources in each cue targeted to different areas on the screen Multiple display resources in a cue can be user-advanced or auto-advanced like a slideshow Each object has a duration, min-duration, and transition type. Min duration is for determining if an object should be displayed if a user tunes in mid-broadcast Poll CTA Poll Results Fun Fact Chat Results Other Custom Event Timeline P15
