Benefits of technology

[0010] It is a first object of this invention to provide an improved method of presenting content.

Problems solved by technology

However, digital audio-visual content that is available for sale on the Internet is still limited because content owners, artists, and publishers are concerned about protecting their copyright works from illegal use.
Unfortunately, Internet piracy and illegal global distribution have been always a headache to the entertainment industry.
In general, DRM distributes digital audio-visual content and limits access to only those people who have acquired a proper license to play the content.
Although 100-percent security is not possible, DRM can prevent naive attackers from bypassing such a DRM system and make it difficult and costly for skilled attackers to compromise such a DRM system.
In addition, DRM can minimise the scope of breaks and limit commercial opportunities for professional attackers.
Typically, the majority of DRM solutions are complicated and expensive to implement, such as a Microsoft Corporation's Media Player system, or Macrovision's systems.
Currently there does not exist a low cost and easy implemented solution providing satisfactory performance.

first specific embodiment

[0109]FIG. 1 shows a DRM (digital rights management) system according to a first specific embodiment of this invention. With reference to FIG. 1, the DRM system includes a session resource manager (SRM) 5 coupled via a suitable connection, such as an SSL (secure sockets layer) connection, to a web server 13. In turn, the web server 13 is used to allow a client 23, such as a user's end station, to access the features provided by the SRM 5 via an appropriate web browser 15 and / or an SSL connection. A server agent platform 14 is implemented and provided in the web server 13.

[0110] The client 23 forms an end station or an end device also referred to as a client device. The client 23 is coupled to, or includes a playback device for displaying content. The playback device includes an AV (audio-visual) decoder 16 and an AV renderer 17. The AV renderer 17 includes a display.

[0111] It should be noted that there may be another client or other clients similar in structure to the client 23.

Abstract

There are a base station and at least one end station which can communicate with each other. The end station generates an access request when wishing to present content. The access request is transferred from the end station to the base station. The base station provides an agent in response to the received access request. The agent is installed in the end station before being implemented by the end station. The implemented agent determines end station data indicative of an identity of the end station. The end station data is transferred from the end station to the base station. The base station authenticates the end station in response to the received end station data for an allowance of the presentation of the content.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention relates to a method of presenting content, a method of authenticating an end station for an allowance of the presentation of content, a digital right management system, a method of decrypting content for presentation, and a method of encrypting content for presentation. [0003] 2. Description of the Related Art [0004] Conventionally, content owners sell premium content in tapes, CDs, and DVDs through traditional outlets. However, due to the success of more powerful personal computers, high speed Internet connections, and superior compression technologies, the way that digital media content, for instance, music or video is produced, distributed, and consumed has been dramatically changed. [0005] Downloading encoded digital audio-visual content files via HTTP, FTP, etc, has gained favour among Internet users because of the immediate access to desired content and no need of a trip to a store or reliance o...
