Problems solved by technology

However, the authorization of digital content by existing digital copyright protection technologies is often only for a single device, that is, users can only use and consume digital content on this device, and cannot use it on other devices in the same way.
This obviously cannot meet the needs of users, and may cause users' resistance to digital copyright protection technology to a certain extent

Embodiment Construction

[0040] As shown in Fig. 1, the present invention is a domain-based home network system providing digital copyright protection. The home network system is composed of a server and a home network. The present invention defines a home network as a user domain, referred to as a domain for short, consisting of a home network server HS and several member devices. The home network server HS is the core device of the user domain, responsible for domain and The server side communicates, manages each member device in the domain, and is qualified to distribute the content license certificate. There may be several domains, two of which are shown in Figure 1, namely domain A and domain B.

[0041] As shown in Figure 1, the member devices of the domain can be: digital TVs, set-top boxes, PCs, notebook computers, multimedia playback devices (such as DVD players, MP3, etc.), portable devices such as multi-functional mobile communication devices, digital DV, etc. Various digital devices. In ...

Abstract

The provided digital copyright protective family network system based on domain comprises: a server, and a family network including a HS and different member devices. Wherein, the HS applies corresponding certificate to the family management network and server providing digital content, and forms a domain as the family network; the server takes the domain as integer for management, and communicates only with the user domain instead of device in the domain. The enciphered digital content can transmit and share freely, and the certificate prohibits the digital content out of the domain. This invention protects both the digital content copyright and the free share for legal user, and ensures both-side legal benefits.

Description

technical field [0001] The present invention relates to a home network for digital copyright protection, in particular to a home network system based on the domain concept and capable of providing copyright protection for various digital contents. Background technique [0002] With the development of computer network and communication technology, the application of network is more and more extensive. At the same time, digital content, that is, digitally encoded multimedia content, such as movies, music, video / audio streaming, digital broadcasting, etc., has also become the mainstream of network dissemination content because of its convenient and lossless transmission and copying characteristics. However, it is precisely because of the characteristics of digital content that it is easier to be pirated and illegally tampered with and used. Therefore, digital content providers urgently need related technologies to protect the copyright of digital content. [0003] The current...
