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.
摘要翻译：公开了一种用于保护流媒体内容的新颖方法和装置。一方面，该装置包括用于控制内容流或内容对象的控制装置，用于在控制装置的控制下解密内容流或内容对象的解密装置，以及用于跟踪内容流或内容对象的实际使用的反馈装置。控制装置可以根据作为流式内容的一部分接收的规则或者通过边带信道来操作。规则可以指定内容的允许使用，包括是否可以复制或传输内容，以及是否在什么情况下接收到的内容可以被“检出”一个设备并且在第二设备中使用。规则还可以包括或指定预算，以及将审计信息收集和/或传送到外部服务器的要求。在不同的方面，设备可以包括被设计为调用插件来辅助呈现内容的媒体播放器。公开了一种“信任插件”，以及使用信任插件的方法，使得设计用于不受保护的内容的媒体播放器可以呈现受保护的内容，而不需要对媒体播放器进行任何改变。在一个方面，流传输的内容可以是多种不同的格式，包括MPEG-4，MP3和RMFF格式。

摘要： The present invention is for an algorithmic method for compressing data. The data is compressed one cycle at a time and stores a data block each cycle. The method includes the steps of forming a storage array of binary bits. The array has a first plurality of columns, a second plurality of rows, a third plurality of right diagonals and a fourth plurality of left diagonals. In the preferred embodiment the array has 30 rows, 30 columns, 59 left diagonals and 59 right diagonals. The array also has a data entry site. The array is also segmented into a plurality of morsels each comprising a collection of a binary bits. A new data block is entered into the data entry site. A fifth plurality of sums is formed representing the sum of binary 1's in each column, each row, each right diagonal and each left diagonal. Each sum is right diagonal and each left diagonal. Each sum is stored into a morsel thereby forming a summation array. Each summation array contains sufficient information to decompress the parent array and a compressed bit of information.

摘要： A method and apparatus for testing materials for use in a laser resonator includes selecting a test fixture apparatus having a housing with an internal chamber volume selected to approximate the internal volume of a predetermined laser resonator and having a pair of sealed windows therein which are removably attached to the housing and having optical coatings selected to match the coating on the optics of a laser. The housing has a removable cover and a gas purging opening. A laser of a predetermined wavelength and power is mounted adjacent the test fixture and is aligned for directing the laser beam through both of the windows of the test fixture. A material is placed in the test fixture and a laser beam directed through the coated windows for a predetermined period of time and thereafter the coated windows are examined for damage or contamination. The test fixtures are also cleaned and certified prior to testing so that a preselected test fixture can determine damage for selective materials used therein.
