摘要: An apparatus and method for encoding and decoding additional information into a steam of digitized samples in an integral manner. The information is encoded using special keys. The information is contained in the samples, not prepended or appended to the sample stream. The method makes it extremely difficult to find the information in the samples if the proper keys are not possessed by the decoder. The method does not cause a significant degradation to the sample stream. The method is used to establish ownership of copyrighted digital multimedia content and provide a disincentive to piracy of such material.

摘要翻译: 一种用于以附加信息编码和解码数字化样本的整体方式的设备和方法。 信息使用特殊键编码。 信息包含在样本中,不会附加到样本流中。 如果解码器没有合适的密钥,该方法使得在样本中找到信息非常困难。 该方法不会导致样品流的显着降解。 该方法用于确定拥有版权的数字多媒体内容的所有权,并对此类材料的盗版行为提供抑制措施。
