During the boot process, a secure wireless display connect module of the BIOS can authenticate a wireless display and determine whether the wireless display can comply with the HDCP. When the secure wireless display connect module determines that the wireless display is HDCP compliant, the secure wireless display connect module can create an ACPI secure blob in which is stored a shared session key generated as part of determining that the wireless display is HDCP compliant. A video authentication session module of the BIOS can then retrieve this shared session key from the ACPI secure blob and use it to encrypt video frames that are to be sent to the wireless display. The video authentication session module may additionally embed a session ID and a timeout into each video frame which the wireless display can employ to detect when the video frame should no longer be displayed.

Systems and methods are provided for temporarily granting access to a digital gateway. One example method includes receiving a request for temporary access to the digital gateway. A temporary access token is generated at a server. The temporary access token is assigned to a user. Access to the digital gateway is granted via the temporary access token. The temporary access token is automatically expired after a pre-set period. Access to the digital gateway is revoked once the temporary access token has expired.

Disclosed is a method for maintaining security of video data of a decryption server. The method comprises registering at least one of an internet protocol (IP) address and a media access control (MAC) address of the security devices, generating a plurality of public key and private key pairs, encrypting and storing private keys comprised in the plurality of public key and private key pairs using a master key provided from a master key management unit, selecting any one of a plurality of public key and private key pairs when the access of the security device is approved and providing a certificate comprising the selected public key to the security device, receiving a symmetric key encrypted with the public key of the certificate from the security device, and decrypting the private key using the master key provided from the master key management unit.

An electronic apparatus which registers a device to a server by using a voice, and a method therefor are provided. The electronic apparatus includes a communication circuit, a microphone, a memory for storing computer executable instructions, and at least one processor configured to execute the computer executable instructions to acquire, from a voice received through the microphone, information on an external device which a user wishes to register, based on an external device corresponding to the acquired information being searched through the communication circuit, control the communication circuit to transmit information on an access point to the external device to enable the external device to communicate with a server, and control the communication circuit to transmit a registration request with respect to the external device to the server.

Provided is a video playback system based on approval of a playback approver. A decryption key that can decrypt an encrypted and stored recorded video is generated only when video playback is approved by a playback approver using an appointed playback approval method and transmitted to the video recording device so that it is possible to prevent leakage of the recorded video with sensitive personal information.

A method and apparatus for secure multimedia transfer provides an encrypted data transfer system that makes transferring multimedia content from a client to any incompatible system or to a system outside the location of the client very difficult.

A method of controlling ability of a client device to access media content available from a server device on a network is provided. The method includes the steps of receiving with the server device a request from the client device via the network for media content and determining with the server device a type of the client device and a type of the media content. Thereafter, a step of applying a policy stored in software form in the server device for determining actions allowable for the client device with respect to the media content is performed. After the applying step, access of the media content is provided to the client device only to an extent defined and permitted by the policy. A server device for functioning as a Digital Media Server (DMS) on a Digital Living Network Alliance (DLNA) network is also disclosed.

Systems and methods for synchronizing the playback of network media across multiple content playback devices, termed herein as “playback devices”, “clients”, or “client devices”. In one implementation, client devices are controlled to parse and buffer media content separately. Once all clients are ready, a controller may cause the client devices to start in a synchronized fashion based on signals sent by the controller. The controller adjusts the timing of the signal so that the outputs are displayed in synchronization on each client device. In other implementations, device lag times may be measured. In still other implementations, a master device may synchronize playback of media content on slave devices. In yet other implementations, devices may buffer and join playback of media content occurring on other devices. In further implementations, the systems and methods may be expanded to include steps of processing authentication for service providers prior to arranging synchronized playback.

A method and system for providing on-site content delivery and on-demand content access. The method comprising recording digital media content on a DMR device, managing distribution of the digital media content to one or more remote devices, automatically distributing the digital media content to the one or more remote devices, the distributed digital media content configured for local hosting at the one or more remote devices, and monitoring consumption of the digital media content distributed to the one or remote devices.

In some embodiments, a method selects an account associated with an application that is displaying content. A plurality of contact options is retrieved where the contact options in the plurality of contact options are able to receive pull notifications for the account. The method ranks the plurality of contact options based on information associated with the account and generates a plurality of pull notification options using the ranking of the plurality of contact options. The plurality of pull notification options is output to the application for display on the application. A pull notification option in the plurality of pull notification options is associated with information to cause an associated contact option to be contacted upon selection of the pull notification option.
