New pending patent applications are published by the USPTO on Thursdays. Both of today's Spotlight Applications concern aspects of digital rights management. Assigned to ActiveVideo, the first application discloses techniques for secure bridging of third-party digital rights management to local security. Assigned to TP Vision (NL), the second application discloses techniques for a common interface host and common interface conditional access module.
20170078721, "Secure bridging of third-party digital rights management to local security," assigned to ActiveVideo Networks, Inc.
Encrypted content from a content provider is received at a central location of a multichannel video programming distributor (MVPD). The content provider is distinct from the MVPD. The content is decrypted and processed in a virtual set-top application associated with a set-top of a customer of the MVPD. The set-top of the customer is located in a customer premises remote from the central location. The processed content is provided over a secure data link to a conditional-access encoder at the central location. The conditional-access encoder encrypts the processed content, which is then transmitted to the set-top of the customer.
20170078711, "Common interface host and common interface conditional access module," assigned to TP Vision Holding B.V. (NL)
The invention provides a Common Interface, CI, host (10) comprising a Universal Serial Bus, USB, controller (30) for connecting to a USB device (31) of a Common Interface Conditional Access Module, CICAM, (20) the USB controller being configured to use--a first logical pipe (33) for transferring control information between the CICAM and the CI host; and--a second logical pipe (35) for transmitting to the CICAM a first CA encrypted signal.--a third logical pipe (37) for receiving a first CA decrypted signal, corresponding to the first CA encrypted signal, from the CICAM, wherein USB isochronous pipes are used as the second logical pipe (35) and the third logical pipe (37) when the first CA encrypted signal originates from a DVB broadcast and USB bulk pipes are used as the second logical pipe (35) and the third logical pipe (37) when the first CA encrypted signal originates from an Internet source.
