1 W3C TPAC 2016 Lisbon / Web-based Signage BG Group Meeting Introduction of Web-based Signage JS Player and proposal of APIs 22 September

2 Newphoria Corporation Offers complete web development services Client-side: PCs, Smartphones, Embedded devices Server-side: Clouds (AWS, etc.) Offers mobile app development services Developing apps for Android, ios Offering Hybrid app development environment service applican ( Offers digital signage solutions Creating contents for digital signage Developing CMS, JS Player 2

3 JS Player Newphoria had developed signage players as R&D for years All players are developed using only Web technologies HTML, CSS, JavaScript, HTTP, WebSocket, etc. The players were developed mainly for Enbedded devices TV sets (Linux, Android TV), STBs (Linux, Android), etc. Newphoria released a commercially based JS Player in 2016 Licensing, Customizing for digital signage operators: NTT Hikari Signage, etc. For now, supporting SONY BRAVIA (Linux, Android TV) Planning to support all TV sets for Japan market, which implement a web runtime for digital signage (Panasonic AF1, LG WebOS, etc.) 3

4 Field Test TPAC 2015 in Sapporo, Japan Newphoria provided the R&D-based JS Player The player played contents in multivendor environment TOSHIBA, SONY, Panasonic, Mitsubishi Electric INTEROP TOKYO 2016 in Makuhari, Japan Newphoria provided the commercially based JS Player NTT provided the digital signage service Hikari Signage SONY provided many TV sets BRAVIA 4

10 Architecture of Web-based Signage System Fetch the player Web Server Terminal Fetch the playlist (JSON) Fetch the contents (image, video) Send logs Adjust clock (Kind of like SNTP) Push commands Push emergency messages CMS Manage the terminals Location, Model name, IP address, HW Serial number, etc. Create playlists Time schedule for each content Upload contents images, videos, etc. Push commands to terminals Reboot, Updating contents, etc. WebSocket Server 10

11 Architecture of Browser-based Player HTML Contents Image/Video Contents, Ticker From CMS via Internet JS Player (JavaScript-base Web Application) Web Browser Runtime (Gecko, Edge HTML, WebKit, Blink, etc.) OS (Linux, Windows, Android, Firefox OS, etc.) JavaScript APIs - Standardized APIs - Proprietary APIs Terminal Hardware (STB, TV Panel) 11

12 Architecture of App-based Player HTML Contents Image/Video Contents, Ticker From CMS via Internet Hybrid Apps (applican) JS Player (JavaScript-base Web Application) Web Browser Runtime (WebView) JavaScript APIs - Standardized APIs - Proprietary APIs OS (Android, ios) Terminal Hardware (STB, Tablet) 12

13 Lack of APIs In my experiences, the standardized APIs are not enough for digital signage player Useful APIs for digital signage are provided by TV set manufacturers as proprietary APIs I hope that non-competitive common APIs are standardized I d like to propose that such APIs are added to the WG charter document Device Information API Network Information API Display Setting API NTP Server Setting API 13

14 Device Information APIs This API allows us to get the information of the device Hardware serial number Manufacturer name Model number Friendly name 14

15 Network Information API This API allows us to get the setting of the network Type of network (Ethernet, Wi-Fi, etc.) IP version (IPv4, IPv6) IP address of the terminal Subnet mask IP address of the default gateway DHCP (true or false) IP address of the DNS MAC address of the terminal 15

16 Display Setting API This API allows us to get and change the setting of the display (panel) Power (ON/OFF) Brightness Contrast Volume (if speakers are built in the panel) Mute (if speakers are built in the panel) 16

17 NTP Server Setting API This API just get and set the IP address or host name of the NTP server to the underlying OS Signage operators sometimes want to change the address of the NTP server set in terminals If the operator manage a lot of terminals, changing the setting remotely is useful 17
