Arris Wins Patent for OTT Policy Enforcement

Arris won a U.S. patent on Tuesday for an invention that could help pay TV distributors authorize devices subscribers can use to view over-the-top video content, including smartphones, tablets and IP-connected TVs.

The invention could help programmer and distributors adhere to content rights deals that limit the types of devices that can be used to watch both entertainment and sports programming.

“For example, a content provider may want to restrict a TV show from being played on a certain type of device, such as a TV show should not be played on smartphones,” Arris notes in the patent, titled, “Policy Enforcement For Multiple Devices Using An Audience Definition.”

Thomas Bahnck, an Intel and Motorola veteran who is currently staff systems engineer at Arris, is named as the inventor on the patent.

Abstract: In one embodiment, a method determines an audience rule to be applied for delivering content. The audience rule specifies an audience that is defined based on a combination of device properties, content properties, and digital rights management (DRM) properties. A device group associated with a group of devices is determined where devices in the device group are associated with content authorization properties, device properties, and digital rights management (DRM) properties. The method then applies the audience rule to the device group to determine any devices in the group of devices in which a content authorization for a device should be altered based on analyzing the content authorization properties, device properties, and digital rights management (DRM) properties of the device group and the combination of device properties, content properties, and digital rights management (DRM) properties of the audience rule.

 

Claims:

  1. A method comprising: determining an audience rule to be applied for delivering content, wherein the audience rule specifies an audience that is defined based on a combination of device properties, content properties, and digital rights management (DRM) properties; determining a device group associated with a group of devices, wherein devices in the device group are associated with content authorization properties, device properties, and digital rights management (DRM) properties; and applying, by a computing device, the audience rule to the device group to determine any devices in the group of devices in which a content authorization for a device should be altered based on analyzing the content authorization properties, device properties, and digital rights management (DRM) properties of the device group and the combination of device properties, content properties, and digital rights management (DRM) properties of the audience rule, wherein the altering determination for a device is determined when the group of devices is changed so that they have content associated with a different DRM property, content authorization properties, or device properties, wherein the altering determination is made after the DRM properties are initially established when the DRM properties are later modified, and are further made prior to receipt of a request for play of content by a device in the group of devices; and wherein determining if affected content authorizations should be altered in the affected device groups comprises: determining if the audience rule added at the system level conflicts with any audience rules at a device group level for the affected device group; and not altering content authorizations for any affected device groups if the audience rule at the system level conflicts with any audience rules at the device group level.
  1. The method of claim 1, wherein applying the audience rule comprises altering the content authorization, or de-authorizing a current content authorization for the device.
  1. The method of claim 1, wherein applying the audience rule comprises changing the DRM properties on the device to alter the content authorization.
  1. A non-transitory computer-readable storage medium containing instructions, that when executed, control a computer system to be configured for: determining an audience rule to be applied for delivering content, wherein the audience rule specifies an audience that is defined based on a combination of device properties, content properties, and digital rights management (DRM) properties; determining a device group associated with a group of devices, wherein devices in the device group are associated with content authorization properties, device properties, and digital rights management (DRM) properties; and applying the audience rule to the device group to determine any devices in the group of devices in which a content authorization for a device should be altered based on analyzing the content authorization properties, device properties, and digital rights management (DRM) properties of the device group and the combination of device properties, content properties, and digital rights management (DRM) properties of the audience rule, wherein the altering determination for a device is determined when the group of devices is changed so that they have content associated with a different DRM properties, content authorization properties, or device properties, wherein the altering determination is made after the DRM properties are initially established when the DRM properties are later modified, and are further made prior to receipt of a request for play by a device in the group of devices; wherein determining if affected content authorizations should be altered in the affected device groups comprises: determining if the audience rule added at the system level conflicts with any audience rules at a device group level for the affected device group; and not altering content authorizations for any affected device groups if the audience rule at the system level conflicts with any audience rules at the device group level.
  1. The non-transitory computer-readable storage medium of claim 4, wherein applying the audience rule comprises altering the content authorization, or de-authorizing a current content authorization for the device.
  1. The non-transitory computer-readable storage medium of claim 4, wherein applying the audience rule comprises changing the DRM properties on the device to alter the content authorization.
  1. An apparatus comprising: one or more computer processors; and a computer-readable storage medium comprising instructions, that when executed, control the one or more computer processors to be configured to: determining an audience rule to be applied for delivering content, wherein the audience rule specifies an audience that is defined based on a combination of device properties, content properties, and digital rights management (DRM) properties; determining a device group associated with a group of devices, wherein devices in the device group are associated with content authorization properties, device properties, and digital rights management (DRM) properties; and applying the audience rule to the device group to determine any devices in the group of devices in which a content authorization for a device should be altered based on analyzing the content authorization properties, device properties, and digital rights management (DRM) properties of the device group and the combination of device properties, content properties, and digital rights management (DRM) properties of the audience rule, wherein the altering determination for a device is determined when the group of device is changed so that they have content associated with a different DRM properties, content authorization properties, or device properties, wherein the altering determination is made after the DRM properties are initially established when the DRM properties are later modified, and are further made prior to receipt of a request for play by a device in the group of devices; wherein determining if affected content authorizations should be altered in the affected device groups comprises: determining if the audience rule added at the system level conflicts with any audience rules at a device group level for the affected device group; and not altering content authorizations for any affected device groups if the audience rule at the system level conflicts with any audience rules at the device group level.

  1. Unquestionably believe that which you stated. Your favorite reason appeared to be on the internet the simplest thing to be aware of. I say to you, I definitely get irked while people consider worries that they plainly do not know about. You managed to hit the nail upon the top and defined out the whole thing without having side-effects , people can take a signal. Will likely be back to get more. Thanks
