 * To create a {@code TvContentRating} object, use the

 * {@link #createRating TvContentRating.createRating} method with valid rating system string

 * constants.

 * <p>

 * 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 {@link TvInputManager#ACTION_QUERY_CONTENT_RATING_SYSTEMS} in its manifest.

 * <h3> Example: Rating system definition for the TV Parental Guidelines</h3>

 * The following XML example shows how the TV Parental Guidelines in the United States can be

 * defined:

 *             <rating android:name="US_TV_MA" />

 *         </rating-order>

 *     </rating-system-definition>

 * </rating-system-definitions>}</pre></p>

 * </rating-system-definitions>}</pre>

 *

 * <h3>System defined rating strings</h3>

 * The following strings are defined by the system to provide a standard way to create

 * {@code TvContentRating} objects.

 *

 * <p>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:

 * </p>

 *

 * <pre>

 * TvContentRating rating = TvContentRating.createRating(

 *         "com.android.tv",

    /**

     * Returns {@code true} if this rating has the same main rating as the specified rating and when

     * this rating's sub-ratings contain the other's.

     * <p>

     * For example, a {@code TvContentRating} object that represents TV-PG with S(Sexual content)

     * and V(Violence) contains TV-PG, TV-PG/S, TV-PG/V and itself.

     * </p>

     *

     * <p>For example, a {@code TvContentRating} object that represents TV-PG with

     * S(Sexual content) and V(Violence) contains TV-PG, TV-PG/S, TV-PG/V and itself.

     *

     * @param rating The {@link TvContentRating} to check.

     * @return {@code true} if this object contains {@code rating}, {@code false} otherwise.
