Notification objects provide information related to the player’s status. TVSDK provides a chronologically sorted list of notification objects, and each notification contains the following metadata:

Element	Description
type	The notification type. Depending on the platform, this property refers to an enumerated type with possible values of INFO, WARN, or ERROR. This is the top-level grouping for notifications.
code	The numerical representation assigned to the notification: Error notification events, from 100000 to 199999 Warning notification events, from 200000 to 299999 Information notification events, from 300000 to 399999 Each top-level range, such as errors, is divided into subranges, such as 101000 through 101999 representing playback errors. The enumeration mediacore.PSDKErrorCode lists the possible values.
name	A string that contains a human-readable description of the code, such as SEEK_ERROR.
metadata	Key/value pairs that contain additional relevant information about the notification. For example, a key named URL would be paired with a value that is a URL related to the notification, such as an invalid URL that caused an error.
innerNotification	A reference to another MediaPlayerNotification object that directly affected this notification. An example might be a notification about an ad-insertion failure that directly corresponds to a time-line insertion conflict. Not all notifications provide an inner notification.
