    • The present invention relates to a bidirectional DID (Digital Information Display) apparatus and a driving method thereof. The bidirectional DID apparatus is able to record and modify voice and video image, and comprises: a message input unit for recording, modifying or inputting voice and video image; a central control unit for controlling bidirectional DID and input/output of the voice and video image; a memory unit for encoding and storing inputted voice and video image and transmitting the stored information according to a request from the central control unit; a display unit for outputting transmitted voice and video image; and a power supply unit for supplying electric power to drive the bidirectional DID. The message input unit includes: a microphone for inputting a user's voice; a camera for recording a user's video image and inputting the recorded video; a receiver for inputting a premade advertisement; a controller for modifying the user's voice, video image and the advertisement, and presetting conditions of the message input unit; and an A/D (Analog-Digital) converter for converting an analog signal into a digital signal when the user's voice, video image and the advertisement are in an analog signal. The memory unit further includes a filter that links the modified voice and video image to the entire voice and video image if some portions thereof are stored after being modified.
    • 双向DID(数字信息显示)装置及其驱动方法技术领域本发明涉及双向DID(数字信息显示) 双向DID设备能够记录和修改语音和视频图像,并且包括:消息输入单元,用于记录,修改或输入语音和视频图像; 中央控制单元,用于控制语音和视频图像的双向DID和输入/输出; 存储单元,用于编码和存储输入的语音和视频图像,并根据来自中央控制单元的请求发送存储的信息; 显示单元,用于输出传送的语音和视频图像; 以及用于供应电力以驱动双向DID的电源单元。 消息输入单元包括:用于输入用户语音的麦克风; 用于记录用户的视频图像并输入记录的视频的相机; 接收器,用于输入预制广告; 控制器,用于修改用户的语音,视频图像和广告,以及预设消息输入单元的条件; 以及A / D(模拟 - 数字)转换器,用于当用户的语音,视频图像和广告处于模拟信号时将模拟信号转换为数字信号。 存储器单元还包括滤波器,如果修改后存储了修改的语音和视频图像的一些部分,则滤波器将修改的语音和视频图像链接到整个语音和视频图像。

    • The present invention relates to an apparatus and method for extracting the representative still images from MPEG video. The apparatus includes a video curve generation unit for calculating the distances between the adjacent frames of all intra frames of input video a certain number of segments; at generation unit for selecting video certain points of the divided video video curve that is a video cumulative curve of curve division unit for dividing the least and generating a the distances; a video curve into one still image images corresponding to curve as representative still images; and a video output unit for outputting the still images selected by the still image generation unit. In addition, the present invention can summarize the video and provide the representative still images to a user at high speed.
    • 本发明涉及从MPEG视频中提取代表静止图像的装置和方法。 该装置包括视频曲线生成单元,用于计算输入视频的所有帧内的相邻帧之间的距离,该特定数量的段; 用于选择视频分割单元的视频累积曲线的划分视频视频曲线的某些点的视频,用于划分最小值并产生距离; 将视频曲线转换为与作为代表静止图像的曲线相对应的一个静止图像图像; 以及用于输出由静止图像生成单元选择的静止图像的视频输出单元。 此外,本发明可以总结视频并且以高速向用户提供代表性的静止图像。
