摘要： A novel method and apparatus for protection of streamed media content is disclosed. In one aspect, the apparatus includes control means for governance of content streams or content objects, decryption means for decrypting content streams or content objects under control of the control means, and feedback means for tracking actual use of content streams or content objects. The control means may operate in accordance with rules received as part of the streamed content, or through a side-band channel. The rules may specify allowed uses of the content, including whether or not the content can be copied or transferred, and whether and under what circumstances received content may be “checked-out” of one device and used in a second device. The rules may also include or specify budgets, and a requirement that audit information be collected and/or transmitted to an external server. In a different aspect, the apparatus may include a media player designed to call plugins to assist in rendering content. A “trust plugin” is disclosed, along with a method of using the trust plugin so that a media player designed for use with unprotected content may render protected content without the necessity of requiring any changes to the media player. In one aspect, the streamed content may be in a number of different formats, including MPEG-4, MP3, and the RMFF format.

摘要： A software architecture and control protocol that provides applications with control over the transport that is frame-accurate, random-access, real-time and stream-based. Conventional server-based data network where media data resides on the server does not provide a frame accurate control of media data playback on a client workstation. The present invention provides control on the client with the implementation of a “client pull” data transport model. According to the present invention, requests for media data are sent from the client to the server one request at a time. The server, upon receiving the requests, retrieves the corresponding frames of media data and transmits the media data back to the client one frame at a time. In this way, the present invention allows a user-interface to provide frame accurate controls on the client workstation, while allowing for real-time playback of media data that resides on the server.

摘要： A software architecture and control protocol that provides seamless playback of multiple clips of media data across a data network. Conventional server-based data network architecture where playback logic resides on the servers does not provide the capability of seamless playback of multiple clips stored in different servers. The present invention allows users to specify a playlist and provides control on the client with the implementation of a “client pull” data transport model. According to the present invention, the playlist is translated into a plurality of frame accurate requests, which are sent from the client to the servers one request at a time. The servers, upon receiving the requests, retrieve the corresponding frames of media data and transmit the media data back to the client. In this way, the present invention allows a user-interface to provide seamless playback of multiple clips that reside on different servers on the client workstation.

摘要： A composite insulator containing means for providing early warning of impending failure due to stress corrosion cracking, flashunder, or destruction of the rod by discharge activity conditions is described. A composite insulator comprising a fiberglass rod surrounded by a polymer housing and connected with metal end fittings on either end of the rod is doped with a dye-based chemical dopant. The dopant is located around the vicinity of the outer surface of the fiberglass rod. The dopant is formulated to possess migration and diffusion characteristics, and to be inert in dry conditions and compatible with the insulator components. The dopant is positioned within the insulator such that upon the penetration of moisture through the housing to the rod through a permeation pathway in the outer surface of the insulator, the dopant will become activated and will leach out of the same permeation pathway or diffuse through the housing. The activated dopant then creates a deposit or stain on the outer surface of the insulator housing. The dopant comprises an oil-soluble dye, an indicator, or a stain compound that can either be visually identified, or is sensitive to radiation at one or more specific wavelengths. The dopant could also be formulated by a nanoparticle enabled material. Deposits of activated dopant on the outer surface of the insulator can be detected upon imaging of the outer surface of the insulator by appropriate imaging instruments or the naked eye.

摘要： Protection of digital content using a specific application of block cipher cryptography is described. The digital content is encrypted using an encryption key and a calculated initialization vector. The digital content includes a plurality of strides of data and each stride includes a string of data to be encrypted and a block of data to be encrypted. The calculated initialization vector to be used to encrypt the block of data is derived from the string of data in the stride to be encrypted. Furthermore, the initialization vector is calculated by performing an exclusive disjunction function on a seed value and the string of data for each stride.
