Brings the Tizen TV player to parity with the other players: closes the five
Tizen issues Bold Media Group filed (#118-#122) and adds the two larger renderer
features it was still missing.
Fixes (#118-#122)
- #118 Sticky "Not authenticated" banner. On TV sleep/wake the socket reconnects
and a heartbeat could land on the fresh, not-yet-registered socket; the server
rejected it and the old handler painted a permanent banner AND dropped the saved
credentials, forcing a re-pair. Heartbeats are now gated on a per-connection
authenticated flag (true only between device:registered and disconnect/auth-error),
the heartbeat stops on connect/disconnect/auth-error, the banner clears on
device:registered, and the auth-error toast is non-sticky.
- #119 app_version stuck at 1.0.0. Resolved at runtime from config.xml via the Tizen
application API, with a fallback constant that build-wgt.sh stamps from config.xml.
- #121 Remote commands. Added a device:command handler (refresh/launch/screen_on/
screen_off; honest no-op toasts for update/reboot/shutdown, which need B2B/MDM
privileges a sideloaded app lacks). Removed the dead device:reload listener.
- #120 Dashboard preview. Added device:screenshot-request + remote-start/remote-stop.
Images capture; video/YouTube fall back to a status card (TV hardware video plane
and cross-origin iframes can't be read into a canvas).
- #122 Updates/boot. Documented the real paths (re-sideload or URL Launcher/MDM
refresh; display-level kiosk/boot settings) since a sideloaded .wgt has no in-app
OTA or config.xml autostart.
Multi-zone layouts (Android parity)
- New ZoneRenderer ports the Android ZoneManager: zones positioned by percent
geometry with z_index/fit_mode/background, assignments grouped by zone_id
(unassigned content goes to the first zone), each zone rotating independently with
the same per-item schedule gating (#74/#75). app.js selects the renderer from
payload.layout; single-zone playback is unchanged.
Video walls (web-player parity; Android has none)
- New WallController mirrors the web player: when payload.wall_config is present the
stage is positioned (vw/vh) as this screen's slice of the wall. The leader plays
normally and broadcasts wall:sync at 4Hz; followers hold the leader's item, align
index, and lock their video to the leader's clock with a latency-compensated drift
controller (hard-seek past 0.3s, gentle +/-3% playbackRate nudge past 0.05s), and
request an immediate position on (re)connect via wall:sync-request. Per-tile
rotation is not applied yet (matches the web player). Wall emits are gated on
auth + connection so a pre-register tick can't trip device:auth-error.
Not ported: video-wall per-tile rotation, plus the minor Android-only reporting
events (device:playback-state, device:log) and the N/A offline-cache events
(device:content-ack/content-delete). None affect on-screen playback.
Verified: JS syntax + headless unit tests of zone grouping/geometry and wall
leader/follower + drift logic. NOT yet validated on Tizen hardware - multi-screen
video sync in particular needs a real wall to tune.
Ports the ScreenTinker player to a Tizen TV / signage web app, speaking the
SAME /device socket.io protocol as the Android player — no server changes; a
Tizen display pairs from the same dashboard.
- app.js: device protocol client — register (pairing_code | device_id+token),
device:registered/paired/unpaired/playlist-update, 15s heartbeat, keep-awake.
Always reaches the server prompt until the display is actually paired; a
saved-but-unreachable server falls back to the prompt (no blank screen); BACK
returns to it.
- player.js: fullscreen single-zone renderer — image (duration timer), video
(play-to-end + loop), YouTube (iframe embed), widget (iframe render endpoint).
- config.xml: Tizen TV manifest; build-wgt.sh packages (signs if Tizen CLI
present, else unsigned); README covers URL-Launcher and signed-.wgt deploy.
Validated: headless protocol test vs the live server passed end-to-end
(register -> pair -> reconnect-auth -> playlist(2) -> content 200); loads +
renders in Chromium with no JS errors.
Not yet ported (fullscreen single-zone covers most signage): multi-zone, video
walls, screenshots, remote control, self-OTA. .wgt is a build artifact (gitignored).
