摘要： PURPOSE: A system and a method for inputting subtitle using a voice recognition device are provided to input subtitle in live broadcasting program through a voice recognition device and a stenographer. CONSTITUTION: A system for inputting subtitle using a voice recognition device includes a voice classification unit(120), a voice recognition unit(130), a subject classification unit(140), a subtitle inputting and correcting unit(150), and a character data transmitter(160). The voice classification unit analyzes frequency components of voice signals output from a TV voice output unit(110) to classify voices. The voice recognition unit recognizes the voice signals to extract character data and calculates the reliability of the character data. The subtitle classification unit extracts a key word using the character data to classify subjects. The subtitle inputting and correcting unit outputs the character data and its reliability, voice classification information and subject information and receives corrected information according to the output data and information to output character data. The character data transmitter receives the corrected character data and transmits the data to a broadcasting server.
摘要翻译：目的：提供使用语音识别装置输入字幕的系统和方法，以通过语音识别装置和速记员输入现场直播节目中的字幕。构成：使用语音识别装置输入字幕的系统包括语音分类单元（120），语音识别单元（130），主题分类单元（140），字幕输入和校正单元（150）以及字符数据发射机（160）。语音分类单元分析从电视语音输出单元（110）输出的语音信号的频率分量以分类语音。语音识别单元识别语音信号以提取字符数据并计算字符数据的可靠性。字幕分类单元使用字符数据提取关键字以对被摄体进行分类。字幕输入和校正单元输出字符数据及其可靠性，语音分类信息和对象信息，并根据输出数据和信息接收校正信息以输出字符数据。字符数据发送器接收经校正的字符数据并将数据发送到广播服务器。

摘要： PURPOSE: An apparatus and a method for inserting Korean character caption in a digital TV broadcasting signal are provided to insert Korean character caption data into a standard TV transport stream by converting a voice signal into caption data. CONSTITUTION: A digital TV tuner device(10) extracts a required digital broadcasting frequency from the received broadcasting signals. A digital broadcasting signal treating section(11) divides the digital broadcasting signal into an image signal and a voice signal. A voice signal analyzer(12) is provided to convert a compressed voice signal into a pulse coded modulation voice signal. A voice signal generating device(13) generates the voice audio signal through a speaker. A voice recognizing caption converting section(14) is provided to convert the voice signal into a caption text. A caption stream generating section(15) creates a user data area. A transmit stream mixing section(16) is provided to compose the voice signals. A transmit stream storing section(17) stores the transmit stream as a file.
摘要翻译：目的：提供一种在数字电视广播信号中插入韩文字幕的装置和方法，通过将语音信号转换为字幕数据将韩文字幕数据插入到标准TV传输流中。构成：数字电视调谐装置（10）从所接收的广播信号中提取所需的数字广播频率。数字广播信号处理部分（11）将数字广播信号分成图像信号和语音信号。提供语音信号分析器（12）以将压缩的语音信号转换成脉冲编码的调制语音信号。语音信号产生装置（13）通过扬声器产生语音音频信号。提供语音识别字幕转换部分（14）以将语音信号转换成字幕文本。字幕流生成部（15）创建用户数据区。提供发送流混合部分（16）以组成语音信号。发送流存储部（17）将发送流存储为文件。
