    • The present invention relates to a non-linear reproduction control method of multimedia stream and an apparatus thereof, the present invention comprises judging a skip direction by interpreting whether a skip request is a forward skip or a backward skip when the skip request is inputted from the user, determining a skip unit by judging whether the user request is a big unit or a small unit, selecting a structural information or semantic information change point of the multimedia stream mostly adjacent to the present reproduction position as a reproduction resume point on the basis of the determined skip direction and skip unit or selecting the reproduction resume point by using the set temporal offset from the preset reproduction position, accordingly it is possible to.
    • 本发明涉及一种多媒体流的非线性再现控制方法及其装置,其特征在于,本发明通过解释当从所述跳过请求被输入时跳过请求是前向跳过还是向后跳跃来判断跳过方向 用户通过判断用户请求是大单元还是小单元来确定跳过单元,基于大部分或小单元选择与当前再现位置大体相邻的多媒体流的结构信息或语义信息改变点作为再现恢复点 确定的跳过方向和跳过单元,或者通过使用从预设再现位置设定的时间偏移来选择再现恢复点,因此可以进行。

    • Disclosed are a method of constructing information on associate meanings between segments of a multimedia stream, which can describe the cause/effect or abstract/detail relationship between segments of the video streams to efficiently browse the video stream and a method of browsing a video using the same. The present invention defines the cause/effect or abstract/detail relationship between the segments, event intervals, scenes, shots, etc. existing within one video stream or between the video streams, and provides a method of describing the relationship in a data region based on the content of a video stream as well as a method of browsing a video by using the information on the cause/effect or abstract/detail relationship obtained by the aforementioned method. Accordingly, a video browsing on associate meanings is available with easy manipulation and easy access to a desired part, thereby providing an effective video browsing interface for easy browsing of desired segments in a short period of time.
    • 公开了一种构建多媒体流的片段之间的关联含义的信息的方法,其可以描述视频流的片段之间的原因/效果或抽象/细节关系以有效地浏览视频流,以及使用该视频流浏览视频的方法 相同。 本发明定义了存在于一个视频流内或视频流之间的片段,事件间隔,场景,镜头等之间的原因/效果或抽象/细节关系,并提供了描述基于数据区域的关系的方法 关于视频流的内容以及通过使用通过上述方法获得的原因/效果或抽象/细节关系的信息来浏览视频的方法。 因此,通过简单的操作和易于访问期望的部分,可以获得关于关联含义的视频浏览,从而提供有效的视频浏览界面,以便在短时间内容易地浏览期望的片段。

    • A rijndael block cipher apparatus including an operational unit that efficiently performs a round operation for encrypting/decrypting a rijndael block cipher and an encryption/decryption method thereof are disclosed. The rijndael block cipher apparatus is mounted in a mobile terminal such as a cellular phone and a PDA or a smart card, which requires a high-rate and small-sized cipher processor, and can encrypt and decrypt important data that requires security at high speed and perform the round operation with respect to upper 64 bits and lower 64 bits which are divided from 128-bit input data. Thus, the cipher apparatus can reduce the time required for encryption/decryption of the rijndael block cipher and the size of the apparatus.
    • 公开了一种rijndael块密码装置,其包括有效执行加密/解密rijndael块密码的循环操作的操作单元及其加密/解密方法。 rijndael块密码装置安装在诸如蜂窝电话和PDA或智能卡的移动终端中,其需要高速率和小尺寸的加密处理器,并且可以加密和解密需要高速安全性的重要数据 并执行从128位输入数据划分的高64位和低64位的循环运算。 因此,加密装置可以减少rijndael块密码的加密/解密所需的时间以及装置的大小。
