Abstract: A contents receiving system uses a digital broadcast wave or a broadband network to enable a user to suitably view main content, and provide a user with subsidiary content information desired by the user. Each of subsidiary content control receivers A (101), B (102) transmits ID information specific to each of the subsidiary content control receivers A (101), B (102), and a request for acquiring subsidiary content, from a communication control unit (405) to a main content receiving display unit 100. The main content receiving display unit 100 uses a content separation control unit (310) to separate a stream into subsidiary content corresponding to the request. Then, a request information input/transmission control unit (313) transmits the separated subsidiary content and the received ID information to the subsidiary content control receiver in question. The subsidiary content control receiver judges from the ID information that the subsidiary content should be acquired.

Abstract translation: 内容接收系统使用数字广播波或宽带网络使得用户能够适当地观看主内容，并向用户提供用户期望的辅助内容信息。 每个副内容控制接收机A（101），B（102）从通信控制单元发送专用于每个辅助内容控制接收机A（101），B（102）的ID信息和用于获取辅助内容的请求 （405）发送到主内容接收显示单元100.主内容接收显示单元100使用内容分离控制单元（310）将流分离成与请求相对应的辅助内容。 然后，请求信息输入/发送控制单元（313）将分离的副内容和接收到的ID信息发送到所讨论的辅助内容控制接收器。 子内容控制接收器从ID信息判断应该获取附属内容。

Abstract: A pulse detection method resistant to changes in an imaging environment is provided.A biological information detection device includes an imaging unit that images reflected light from a target object and outputs a video signal including a plurality of wavelength components, a reflected light analysis unit that obtains a wavelength and an intensity of the reflected light from the video signal, a wavelength fluctuation detection unit that detects difference between the wavelength of the reflected light of each time and the wavelength of the reflected light of a time before each of the time, and a pulse detecting unit that detects a change in accordance with a time of the detected difference as a pulse.
