Adobe Access uses “soft enforcement” of time-based license restrictions. If a time right expires during playback of a video, the default behaviour of Adobe Access is to not restrict playback until the next time the video stream is recreated (by calling
While soft enforcement is the default behavior, you can also enable hard enforcement by performing one of the following tasks:
DRMManager.loadVoucher(LOCAL_ONLY).An error code indicates that the locally-stored license is no longer valid.
Netstream.stop().When the user clicks the Play button, you can seek to the recorded location and then call
Specifies the date after which a license is valid.
Example use case: Use an absolute date to issue content licenses ahead of the availability date of an asset, or to enforce an “embargo” period.
Specifies the date after which a licenses expires.
Example use case: Use an absolute expiration date to reflect the end of distribution rights.
Specifies the license expiration date, expressed relative to the date of packaging.
Example use case: In an automated packaging process, use a single policy with this option for a series of videos to set the expiration date to 30 days relative to the date of packaging.
Specifies the duration a license can be cached on disk in the client’s local License Store without requiring reacquisition from the license server. You can alternatively specify an absolute date/time after which a license can no longer be cached.
Once the cache expiration date has passed, the license is no longer valid, and the client must request a new license from the license server.
Example use case: Use the license caching duration to specify a fixed amount of time valid for a particular license, such as in a rental use case. A 30-day rental can be specified (with license caching) to indicate the total license duration within which to consume the content.
Specifies the duration a license is valid after the first time it is used to play protected content.
Example use case: Some business models allow a rental period of 30 days but, once playback begins, it must be completed in 48 hours. This 48-hour longevity of the license is defined as the playback window.
Specifies the frequency in which the client will synchronize its state with the server. If the client has been issued an out-of-band license (without a license server being contacted), usage rules may specify that the client must send synchronization messages to the server in order to synchronize the client’s secure time and report client state to the server.
The synchronization behavior is defined using the following parameters:
This usage rule is supported by Adobe Access clients version 3.0 and higher. The behavior on older clients depends on the minimum client version supported by the license server. See, Minimum Client Version.
