Watching live television shows and other continuous, channel-based content is a big part of the
|
|
TV experience. Android supports receiving and playback of live video content through the TV Input
|
|
Framework. This framework provides a unified method for receiving audio and video channel content
|
|
from hardware sources, such as HDMI ports and built-in-tuners, and software sources, such as
|
|
video streamed over the internet.
|

|

|
|
The framework enables developers to define live TV input sources by implementing a TV input
|
|
service. This service publishes a list of channels and programs to the TV Provider. The live TV
|
|
app on a TV device gets the list of available channels and programs from the TV Provider and
|
|
displays them to a user. When a user selects a specific channel, the live TV app creates a
|
|
session for the associated TV input service through the TV Input Manager, and tells the TV input
|
|
service to tune to the requested channel and play the content to a display surface provided by
|
|
the TV app.

The TV Input Framework is designed to provide access to a wide variety of live TV input sources
|
|
and bring them together in a single user interface for users to browse, view, and enjoy content.
|
|
Building a TV input service for your content can help make it more accessible on TV devices.

The APIs for the TV Input Framework are available in the L Developer Preview and you can
|
|
review them in the preview API reference docs. However, more changes are planned, so stay tuned
|
|
for additional information with the official Android platform launch.
