摘要： Methods, apparatus, and systems for signal continuity assessment using embedded watermarks are provided. The embedded watermarks are recovered from the content and one or more attributes associated with the recovered watermarks are identified. A continuity of the content can then be assessed in accordance with the one or more attributes. The continuity assessment may be based on a variety of factors, including but not limited to a determined heartbeat of the recovered watermarks, a density, separation, location, or extent, of the recovered watermarks, as well as information associated with the watermarks, such as a stego key, channel bits, packet numbers, a fingerprint, or the like.
摘要翻译：提供了使用嵌入水印进行信号连续性评估的方法，装置和系统。从内容中恢复嵌入的水印，并且识别与恢复的水印相关联的一个或多个属性。然后可以根据一个或多个属性来评估内容的连续性。连续性评估可以基于各种因素，包括但不限于恢复的水印的确定的心跳，恢复的水印的密度，分离，位置或范围，以及与水印相关联的信息，例如作为隐藏密钥，信道位，分组号，指纹等。

摘要： A system that redefines how data is distributed on a conventional writable compact disc (CD-R/E). A rearrangement of the data on the disc provided during the writing operation preserves eight-to-fourteen channel frames and the control and display (C&D) channel and burst error mitigation while providing a direct access storage device (DASD) format and capability. The CD-DASD format is suitable for preformatting the CDs and has constant size sectors recorded contiguously along the spiral track. Each sector is independently addressable and synchronous with the C&D data word and ATIP channel words on the CD-R disc. The system uses the components of a conventional CD device and a mapping controller address translator to encode and decode the data bytes using a conventional CIRC encoder/decoder. A rectangular product code of C1 and C2 CIRC subcodes is provided that is interleaved to mitigate the effects of handling. The system provides for locking in on the changing data frequency that occurs when moving between spirals of the CD allowing reading and writing to occur while the CD is coming to the proper speed.
摘要翻译：重新定义数据如何在常规可写光盘（CD-R / E）上分配的系统。在写入操作期间提供的盘上的数据的重新排列在提供直接访问存储设备（DASD）格式和能力的同时保留八到十四个通道帧以及控制和显示（C＆D）通道和突发错误减轻。 CD-DASD格式适用于预格式化CD，并具有沿着螺旋轨道连续记录的恒定尺寸的扇区。每个扇区可独立寻址并与CD-R光盘上的C＆D数据字和ATIP通道字同步。该系统使用常规CD设备的组件和映射控制器地址转换器来使用传统的CIRC编码器/解码器对数据字节进行编码和解码。提供C1和C2 CIRC子码的矩形产品代码，其被交织以减轻处理的影响。该系统提供锁定在CD的螺旋之间移动时发生的变化的数据频率，允许在CD达到适当速度时发生读取和写入。
