  • Patent number: 11088999
    Abstract: A “trusted domain” is established within which content received from a communications network, e.g., a cable TV network, is protected from unauthorized copying thereof, in accordance with the invention. In an illustrative embodiment, the trusted domain includes a device associated with a user which receives content from the cable TV network. The content may be encrypted using a content key in accordance, e.g., with a 3DES encryption algorithm before it is stored in the device. In addition, a first encrypted content key version and a second encrypted content key version are generated by respectively encrypting the content key with a public key associated with the device and another public key associated with the user, in accordance with public key cryptography. The first and second encrypted content key versions are stored in association with the encrypted content in the device storage.

  • Patent number: 11082723
    Abstract: Apparatus and associated methods that allow a user (e.g., cable or satellite network subscriber) to access content, such as a video program, from a location outside the subscriber's network, with dynamic or adaptive insertion of secondary content (e.g., advertisements or promotions) that are more relevant for that context. In one embodiment, a personal content server streams the content to the subscriber over a network connection from the local e.g., (subscription) network to a remote network upon authorization by a content manager process; secondary content is evaluated and selectively inserted or replaced depending on factors such as the user's remote location, the configuration of their platform, the date and time of their access request, and/or the subject matter of the primary content.

  • Patent number: 10848806
    Abstract: A technique for securely transferring content from a first device in a first layer to a second device in a second layer. In one embodiment, the first device is a device in a trusted domain and the second device is outside of the trusted domain. Transfer of protected content to another device may require authentication of the receiving device. A rights file which specifies the rights of the receiving device to use the protected content, according to its security level is also transferred. These rights may concern, e.g., the number of times the receiving device may transfer the protected content to other devices, the time period within which the receiving device may play the protected content, etc. The higher the security level of the receiving device, the more rights accorded thereto. A minimum security level requirement may be imposed in order for protected content to be transferred to a device.

  • Patent number: 9781462
    Abstract: In response to a request initiated by a user at a user terminal, selected entertainment programming content, when broadcast, is recorded at a location remote from the user terminal. The request is communicated through a communications network, e.g., cable TV network, which is also used for transmission of entertainment programming content to user terminals. The recorded programming content is stored in a storage space at the remote location, which is allocated to the user terminal. In response to a review request from the user terminal, the recorded programming content is retrieved from the storage space allocated thereto, and transmitted to the user terminal through the communications network. The presentation of the recorded programming content may be manipulated by the user to perform rewinding, pausing and fast-forwarding thereon.

  • Patent number: 9313530
    Abstract: Technique for securely transferring programming content from a first device in a first layer to a second device in a second layer. Upon request to transfer protected content to the second device, the first device authenticates the second device. After authentication, the first device transfers the protected content and a rights file associated therewith to the second device. The rights file specifies the rights of the second device to use the protected content, according to its security level. These rights may concern, the number of times that the second device may subsequently transfer the protected content to other devices, the time period within which the second device may play the protected content, etc. The higher the security level of the second device is, the more rights accorded thereto. The second device may further need to meet a minimum security level in order for it to receive the protected content.

  • Patent number: 8799972
    Abstract: To effectively utilize the bandwidth of a cable TV network, which is limited, analog TV program material is digitized and compressed before its transmission over the network. The resulting signals consume only part of the analog TV band traditionally needed for transmission of the analog TV program material. The newly available bandwidth in the analog TV band may be utilized for other cable TV services, e.g., video-on-demand (VOD) services. A reception gateway is employed at a user location to frequency-translate any VOD signals, transmitted through the analog TV band, to another frequency band, thereby avoiding disturbing the normal operation of a set-top terminal in receiving the analog TV program material through the analog TV band at the user location.
