Abstract: To provide audience measurement services without requiring broadcasters to install additional watermarking equipment, a small video capture device may receive a video signal viewed by an audience member, the signal including embedded closed captioning data, and may decode and transmit the closed captioning data to an audience measurement server. The measurement server may receive the data and compare the received data to a database of closed captioning text to identify matches. The database may be populated via one or more additional capture devices receiving local or national broadcast signals, or with data separately provided by broadcasters. When a match is found, the measurement server may determine that the audience member is watching a program having the corresponding closed captioning. Dynamically generated confidence scores may allow for reliable identification of audience members of content, even with very short closed captioning data lengths.

Abstract translation: 为了提供观众测量服务而不要求广播者安装附加的水印设备，小的视频采集设备可以接收由观众观看的视频信号，该信号包括嵌入的隐藏字幕数据，并且可以将隐藏的字幕数据解码并传送给观众 测量服务器。 测量服务器可以接收数据并将接收到的数据与隐藏字幕文本的数据库进行比较以识别匹配。 数据库可以通过接收本地或全国广播信号的一个或多个附加捕获设备或由广播商单独提供的数据来填充。 当找到匹配时，测量服务器可以确定观众成员正在观看具有相应隐藏字幕的节目。 动态生成的置信度分数可以允许对内容的观众成员进行可靠的识别，即使是非常短的隐藏字幕数据长度。
