Alexa.VideoRecorder Interface 3
Implement the Alexa.VideoRecorder interface in your Alexa skill so that users can find and schedule a recording for a specified video item. Also implement this interface to cancel a scheduled recording or inquire about the recording space left on a digital video recorder (DVR). To record video content that's currently playing, implement the Alexa.RecordController interface instead.
For the list of languages that the Alexa.VideoRecorder interface supports, see List of Alexa Interfaces and Supported Languages. For the definitions of the message properties, see Alexa Interface Message and Property Reference.
Utterances
The Alexa.VideoRecorder interface uses the pre-built voice interaction model. After the user says one of the following utterances, Alexa sends a corresponding directive to your skill.
The following examples show some user utterances:

أليكسا، سجلي الحلقة اللي بعدها من لعبة نيوتن
أليكسا، سجلي الحلقات الجديدة من مسامير
أليكسا، ألغي تسجيل مسامير

Reportable properties
The Alexa.VideoRecorder interface uses the following properties. You identify that you support the properties in your discovery response.
| Property | Description | Type |
|---|---|---|
|
|
Indicates the type of graphical user interface shown to the user. |
Boolean |
|
|
Indicates the percentage of storage used on the recording device. |
Integer |
Discovery
You describe endpoints that support Alexa.VideoRecorder by using the standard discovery mechanism described in Alexa.Discovery.
Set retrievable to true for the properties that you report when Alexa sends your skill a state report request.
For change reporting, set proactivelyReported to false for the Alexa.VideoRecorder interface.
Set proactivelyReported to true as appropriate for other interfaces that you implement in your skill.
Use TV, STREAMING_DEVICE, GAME_CONSOLE, or other appropriate display category. For the full list of display categories, see display categories.

Proactive Discovery with AddOrUpdateReport
When a user adds a new endpoint to their account or makes changes to an existing endpoint, you must proactively send an Alexa.Discovery.AddOrUpdateReport message to the Alexa event gateway. You can include all the endpoints associated with the user account, or only the new or updated endpoints. You can choose based on your skill implementation. For details, see AddOrUpdateReport.
Directives
Alexa sends the following Alexa.VideoRecorder interface directives to your skill.
The directives include an entity object that specifies the requested content. For details, see Entity Types for Video Content.
