# TvContentRating Added in[API level 21](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) # TvContentRating *** ** * ** *** Kotlin\|[Java](https://developer.android.com/reference/android/media/tv/TvContentRating "View this page in Java") ``` class TvContentRating ``` |---|----------------------------------------------------------------------------------------------------------------------| | [kotlin.Any](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-any/index.html) || | ↳ | [android.media.tv.TvContentRating](https://developer.android.com/reference/kotlin/android/media/tv/TvContentRating#) | A class representing a TV content rating. When a TV input service inserts the content rating information on a program into the database, this class can be used to generate the formatted string for[TvContract.Programs.COLUMN_CONTENT_RATING](https://developer.android.com/reference/kotlin/android/media/tv/TvContract.Programs#COLUMN_CONTENT_RATING:kotlin.String). To create a object, use the[TvContentRating.createRating](https://developer.android.com/reference/kotlin/android/media/tv/TvContentRating#createRating(kotlin.String,%20kotlin.String,%20kotlin.String,%20kotlin.String))method with valid rating system string constants. It is possible for an application to define its own content rating system by supplying a content rating system definition XML resource (see example below) and declaring a broadcast receiver that filters[TvInputManager.ACTION_QUERY_CONTENT_RATING_SYSTEMS](https://developer.android.com/reference/kotlin/android/media/tv/TvInputManager#ACTION_QUERY_CONTENT_RATING_SYSTEMS:kotlin.String)in its manifest. ### Example: Rating system definition for the TV Parental Guidelines The following XML example shows how the TV Parental Guidelines in the United States can be defined:
```kotlin ``` ### System defined rating strings The following strings are defined by the system to provide a standard way to create`TvContentRating`objects. For example, to create an object that represents TV-PG rating with suggestive dialogue and coarse language from the TV Parental Guidelines in the United States, one can use the following code snippet: ```kotlin TvContentRating rating = TvContentRating.createRating( "com.android.tv", "US_TV", "US_TV_PG", "US_TV_D", "US_TV_L"); ``` #### System defined string for domains | Constant Value | Description | |----------------|--------------------------------------------------| | com.android.tv | Used for creating system defined content ratings | #### System defined strings for rating systems | Constant Value | Description | |----------------|---------------------------------------------------| | AR_TV | TV content rating system for Argentina | | AU_TV | TV content rating system for Australia | | BR_TV | TV content rating system for Brazil | | CA_TV_EN | TV content rating system for Canada (English) | | CA_TV_FR | TV content rating system for Canada (French) | | DTMB | DTMB content rating system | | DVB | DVB content rating system | | ES_DVB | DVB content rating system for Spain | | FR_DVB | DVB content rating system for France | | ISDB | ISDB content rating system | | KR_TV | TV content rating system for South Korea | | NZ_TV | TV content rating system for New Zealand | | SG_TV | TV content rating system for Singapore | | TH_TV | TV content rating system for Thailand | | US_MV | Movie content rating system for the United States | | US_TV | TV content rating system for the United States | #### System defined strings for ratings | Rating System | Constant Value | Description | |---------------|-----------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | AR_TV | AR_TV_ATP | Suitable for all audiences.
