Disclosed herein are a method and device for transmitting digital content. A selection of at least one device authorized to receive digital content is detected. It is identified whether each selected device contains a session key that corresponds to a local session key. Digital content is transmitted to each device whose session key corresponds to the local key. Digital content is prevented from transmission to unselected devices not having a corresponding session key.

A server device that includes a receiving unit, a browse page creation unit, a mail creation unit, and a mail transmission unit. The receiving unit receives an image transmitted from an electronic camera via a wireless network. The browse page creation unit creates a browse page for browsing the transmitted image from the electronic camera, the image having been received by the receiving unit. The mail creation unit creates a notification mail for introducing the browse page that has been created by the browse page creation unit to a person other than a user of the electronic camera. Furthermore, the mail transmission unit transmits the notification mail that has been created by the mail creation unit to a specified mail address.

An apparatus for decoding a media stream includes a memory module, a processor module coupled to the memory module, wherein the memory module contains instructions that when executed by the processor cause the apparatus to perform the following: receive a media stream including a segment signaling information and a plurality of segments, wherein the plurality of segments includes encoded and unencoded segments, wherein the segment signaling information includes identification of at least two segment groups each including at least one segment, identify at least one segment group using the segment signaling information in the media stream, identify at least one segment decoding algorithm for the at least one segment group, identify at least one decoding key for the at least segment group, and decode each encoded segment within the at least segment group using the at least segment decoding algorithm and the at least one decoding key.

A method for enforcing entitlements includes configuring a wide variety of entitlements at a server; determining applicable combination of entitlements for a given client request; sending entitlements to the requesting client securely; handling entitlement information securely on a plurality of client devices at run time; storing entitlement information securely on a plurality of client devices for offline use; and enforcing entitlements on a plurality of client devices. The method employs manipulation of manifest files by a proxy that may be included in the client device or located in the network.

A system for validating an authorization request to facilitate controlling access to content or computer commands, in which the access is requested by multiple entities operated on discrete computing environments. The techniques make use of a system including a switchboard and a rule engine that collect parameter sets required for validation from the entities and dynamically generate a lock and key combination based on the collected parameter sets. The key of the lock and key combination allows the system to validate each entity independently regardless of the required parameters specified in the lock and key combination.

Provided are a video information system and a method of providing video data access history. Biomedical information or non-biomedical information that may authorize a user who is accessing video data stored in the video information system is stored to be linked to the video data as metadata of the video data, and thus, an authorized user who later accesses the video information system may identify an identity of a user who has accessed the video data. If it is determined that the user is an unauthorized user, the biomedical information or the non-biomedical information of the user may be used to determine who the unauthorized user is.

A system that incorporates teachings of the present disclosure may include, for example, a gateway comprising a controller to receive from a communication device a request for media content, receive a key and a record associated with the communications device from an interactive television system, wherein the record comprises a list of entitled media content, determine whether the requested media content is in the list of entitled media content, retrieve the requested media content from the interactive television system when the requested media content is determined to be in the list of entitled media content, encrypt the retrieved media content utilizing the key, and transmit the encrypted media content to the communications device. Other embodiments are disclosed.
