+<p>
+  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.
+</p>
+<p>
+  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.

+<p>
+  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.
+</p>
+
+<p>
+  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.
