DVB-I Client

Android library that implements a DVB-I client for the Open Red Button (ORB) stack. DVB-I can be integrated into an Android Tv Input Service: the library discovers service lists, presents DASH and broadcast instances, and feeds channel/EPG data into Android TvContract.

This is a library, not a standalone app. Host it from your own TvInputService (or equivalent Android TV input).

What it does

• Fetches and parses a DVB-I service list (ETSI TS 103 770) and keeps it versioned.
• Tunes a service or a specific service instance (DASH via dash.js in a WebView, or RF/broadcast via the host tuner).
• Publishes programmes from the DVB-I content guide into Android TvContract.
• Surfaces linked HbbTV applications, parental rating, tracks/components, and stream events to the integrator.

Using the library

Instantiate once from your TV input or setup flow, then search and tune:

DvbIClient.instantiate(context);
DvbIClient client = DvbIClient.getInstance();

client.setTvInputCallback(/* tuner, video, parental callbacks */);
client.startServiceSearch("https://example.com/servicelist.xml");

client.tune(serviceUid, /* instanceIndex, or -1 for highest priority */ -1);
View dashView = client.getView(); // overlay for DASH playback

startServiceSearch(null) / updateServiceList(null) use the built-in HbbTV test-harness URL (http://hbbtv1.test/servicelist.xml). Production integrators should pass their own service list URL.

Host integration is through:

• ITvInputCallback — tuner, video availability, parental override
• DvbCallback / HbbTVCallback (from companionlibrary) — channel/EPG and HbbTV signalling
• DvbIClient.Callback — DVB-I playback and instance changes

Layout

• src/main/java/org/orbtv/dvbiclient/ — DvbIClient and supporting managers (tune, EPG, database)
• src/main/java/org/orbtv/dvbiclient/model/ — service list, instance, programme, and related types
• src/main/assets/polyfill/ — DASH player page (dvbipage.html + dash.js)

Depends on companionlibrary for shared channel/EPG models and callbacks.

Minimum SDK 28. Build as an Android library (build.gradle) or as the AOSP static Java module org.orbtv.dvbiclient.
