| 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. |

| 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. |
