Embodiment Construction

[0046] A content reproduction control system in one embodiment of the present invention will be described below with reference to the drawings.

[0047] figure 1 is a schematic diagram showing the conceptual configuration of the content reproduction control system 1 as a whole in this embodiment of the present invention.

[0048] The content reproduction control system 1 is a system for securely controlling reproduction when a user uses encrypted content to be distributed from a distribution center (that is, a service provider) through a network or the like in a terminal device. Such as figure 1 As shown, this system has a distribution center 101 that distributes licenses or the like to give content and content use permission, a plurality of terminal devices 102a to 102c (three devices are shown in the figure) that use these contents, and The Internet is such a network 103 interconnected.

[0049] The distribution center 101 includes a rights management server 101a that man...

Abstract

A content reproduction control system (1) comprising a server apparatus (101b) and a terminal apparatus (102) that are connected via a communication path (103), wherein the server apparatus includes: based on time information attached to a content, a control information generation unit (1106) operable to generate control information (1503) for specifying a range for permitting or prohibiting a user's predetermined operation in the terminal apparatus; and a distribution unit (1110) that distributes the control information to the terminal apparatus (102), the terminal apparatus includes: a content use unit (2108) operable to use the content; a receiving unit (2101) operable to receive the control information; and a content use control unit (2106) operable to control reproduction of the content based on the received control information.

Description

technical field [0001] The present invention relates to a system in which a server device distributes digital content such as video and music through communication and broadcasting, and a user uses the digital content in a terminal device. Specifically, it relates to a system for controlling time skip and fast-forward such specific reproduction (a trick play) of a specific portion of digital content in a terminal device according to the provider's intention. Background technique [0002] In recent years, due to the needs of practical use, it has been developed to distribute digital contents such as music, video and games from server devices to terminal devices through communication means such as the Internet, digital broadcasting, and cable television (CATV) (hereinafter referred to as content ), and content distribution services using these contents in terminal devices. A public system for content distribution employs copyright protection technology to protect the copyrigh...
