Abstract:
PURPOSE: A broadcast signal receiving device for controlling a broadcast program using a signature of program information and a method thereof are provided to control the use of a broadcast program using a signature included in program information. CONSTITUTION: A communication unit(210) receives a broadcast signal. An extracting unit(220) extracts a broadcast program and program information from the received broadcast signal. A determining unit(230) generates a signature for verification to check whether the program information is changed from the extracted program information. The determining unit compares the signature of the extracted program information with the signature for the verification. The determining unit determines the validity of the program information.
Abstract:
A method of obtaining data associated with a content item, comprising the steps of obtaining (32) an identifier for the content item, performing (33) a database lookup to obtain the data using the identifier and submitting (37) the content item to an output (210) for processing by a human (200) if the database lookup fails to obtain the data, characterized by a step (35) of automatically classifying the content item into one of a number of classes, and by performing at least one of the other steps conditionally based upon the classification of the content item. In an embodiment the content item is submitted to the output only if (36) the database lookup fails to obtain the data and the content item was classified into one of a number of predetermined classes. Also a server (300) and a computer program product arranged to carry out the method.
Abstract in simplified Chinese:本案系揭示用于与音频/视频内容发送及分配系统一起使用之以讯征为基础之频道或节目之辨识设备及方法。所揭示之设备及方法系取得一个参考音频信号及一个与音在一个消费位置处消费之音频/视频内容相关之一个音频信号之零交越之间之尖峰信号振幅。用于该些信号之讯征系使用尖峰信号振幅的总和而被发展出,且该些讯征系被比较,以辨识该消费位置处消费之该音频/视频内容。
Abstract in simplified Chinese:本案揭示把视听广播内容,从第一/源头设备经中间设备,移交到第二/目标设备。中间设备之置设,是要利用其本身机构接收与第一/源头设备所接收之相同视听广播内容。若中间设备检测到第一/源头设备播出视听内容中断,中间设备即把所接收之视听广播,存储在时间挪移记忆器内。当检测到有第二/目标存在时,中间设备即连接至第二/目标设备,并开始时间挪移流送至第二/目标设备。
Abstract in simplified Chinese:本发明系揭示一种适应地收集听众信息数据之方法及设备。该揭示之方法及设备系监视系统因子,且由定位成根据该被监视之因子而收集听众测量数据之复数个传感器中选择一或多个传感器。因此,该揭示之方法及设备系借由选择其收集之听众测量数据之一个数量及/或形式而适应其所面对之情况。
Abstract:
PURPOSE: A validation and fast channel change for the broadcasting system are provided to transmit data service without delay before decoding a channel to offer a video signal. CONSTITUTION: A terminal receives first data with a part of data service by using a broadcasting channel(S5.1). The terminal acquires a first signature data by processing the first data by using a signature generation algorithm(S5.2). The terminal transmits the first signature data to a content server by using a data channel(S5.3). The content server compares a signature acquired by processing the first data with a part of data service with the first signature data by using a corresponding signature generation algorithm(S5.4).
