| ↳ | [android.media.tv.TvInputManager](https://developer.android.com/reference/kotlin/android/media/tv/TvInputManager#) |
Central system API to the overall TV input framework (TIF) architecture, which arbitrates interaction between applications and the selected TV inputs.
There are three primary parties involved in the TV input framework (TIF) architecture:
- The**TV input manager**as expressed by this class is the central point of the system that manages interaction between all other parts. It is expressed as the client-side API here which exists in each application context and communicates with a global system service that manages the interaction across all processes.
- A**TV input** implemented by[TvInputService](https://developer.android.com/reference/kotlin/android/media/tv/TvInputService)represents an input source of TV, which can be a pass-through input such as HDMI, or a tuner input which provides broadcast TV programs. The system binds to the TV input per application's request. on implementing TV inputs.
- **Applications** talk to the TV input manager to list TV inputs and check their status. Once an application find the input to use, it uses[TvView](https://developer.android.com/reference/kotlin/android/media/tv/TvView)or[TvRecordingClient](https://developer.android.com/reference/kotlin/android/media/tv/TvRecordingClient)for further interaction such as watching and recording broadcast TV programs.

static val ACTION_QUERY_CONTENT_RATING_SYSTEMS: String
```
Broadcast intent action used to query available content rating systems.
The TV input manager service locates available content rating systems by querying broadcast receivers that are registered for this action. An application can offer additional content rating systems to the user by declaring a suitable broadcast receiver in its manifest.
Here is an example broadcast receiver declaration that an application might include in its AndroidManifest.xml to advertise custom content rating systems. The meta-data specifies a resource that contains a description of each content rating system that is provided by the application.
```kotlin
```
In the above example, the`@xml/tv_content_rating_systems`resource refers to an XML resource whose root element is``that contains zero or more``elements. Each` `element specifies the ratings, sub-ratings and rating orders of a particular content rating system.
Value: "android.media.tv.action.QUERY_CONTENT_RATING_SYSTEMS"

### updateTvInputInfo
Added in[API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
fun updateTvInputInfo(inputInfo: TvInputInfo): Unit
```
Updates the`TvInputInfo`for an existing TV input. A TV input service implementation may call this method to pass the application and system an up-to-date`TvInputInfo`object that describes itself.
The system automatically creates a`TvInputInfo`object for each TV input, based on the information collected from the`AndroidManifest.xml`, thus it is not necessary to call this method unless such information has changed dynamically. Use[TvInputInfo.Builder](https://developer.android.com/reference/kotlin/android/media/tv/TvInputInfo.Builder)to build a new`TvInputInfo`object.
Attempting to change information about a TV input that the calling package does not own does nothing.
| Parameters ||
|-------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `inputInfo` | [TvInputInfo](https://developer.android.com/reference/kotlin/android/media/tv/TvInputInfo):The`TvInputInfo`object that contains new information. This value cannot be`null`. |
| Exceptions ||
|--------------------------------------|---------------------------|
| `java.lang.IllegalArgumentException` | if the argument is`null`. |
