Service and system requirements from the major digital signage service providers Requirements for Mapping the requirements for Web environment Digital Signage 1 Targeted commercial exposure  Need to define metadata within the commercial to provide the information on their distributions  Need a dynamic Tag to provide situation-aware service Measurements for the exposure to 2 effectiveness analysis  Need elements(or attributes) for tracking within the commercial Interoperability on heterogeneous 3 H/W environments Linkage with mobile and customer 4  Need new Device API to communicate with the digital signage devices device (can be added on the existing Device API) Wide adaptability on the screen 5 size by content size  Extended functionality to carry the Web Objects (Beacon, Content PAN TM , etc.)  Be able to provide targeted information using the distribution 6 Cost-effective system build-up information within the contents’ metadata Particular content delivery for 7 emergent situations  Need a Tag on the exposure to provide situation-aware service Robustness operation along with 8 legacy systems 4

Problem Statement  The APIs to provide the sensor data from digital signage to the Web browsers  The interfaces that enables the Web browser to access to the various sensors (camera, proximity, CO2, lux, temperature, humidity, etc.)  Besides the APIs that has been dealt at the Device APIs WG, the standard interfaces that can support the content rendering on the public device environment like digital signage  Description of content distribution condition for digital signage  Ontology description for each content or segment which can be selectively exposed by the environmental conditions  Interoperability with the legacy W3C Media Ontology to be able to interoperable with current Web [1] 6

Our Approach Metadata for Distribution Condition Name Type definition Description (attName=“minUserObjCount", attValue=“Integer"), (att - Describe the expected number of users Name=“maxUserObjCount", attValue=“Integer") - Describe the recognized number of users from th userObjCount e digital signage device (attName=“minUserObjBehavior", attValue=“Decimal"), - Describe the motion data of expected users (attName=“maxUserObjBehavior", attValue=“Decimal") userObjBehavior (attName=“minTemperature", attValue="Decimal"), - Describe the expected temperature data. (attName=“maxTemperature", attValue="Decimal"), temperature (attName=“unit” attValue=“String”) (attName=“minLux", attValue="Decimal"), (attName=“m - Describe the expected lux data. lux axLux", attValue="Decimal") (attName=“minSound", attValue="Decimal"), (attName= - Describe the expected level of sound data. soundLevel “highSound", attValue="Decimal") (attName=“minCo2", attValue="Decimal"), (attName=“hi - Describe the expected CO2 density data. co2 ghCo2", attValue="Decimal") (attName=“proximity", attValue=“String") - Describe the expected distance proximity data. proximity 7

Suggestions  Device APIs for emerging Ad. Devices  Device APIs need to be extended to be able to support wide range of media, from various sensors to the new execution environment like digital signage.  Metadata ontology for Ad. exchanges  The metadata for environmental condition description and content distribution condition are also required. Cooperation with current WGs to keep the consistency and interoperability with legacy standards and technologies is needed as well 8
