    • The present technology relates to a reception device, a reception method, and a program therefor that enable improvement in reception performance when information on a frequency band in which no data is transmitted is known. The reception device receives a broadcast wave of an OFDM signal transmitted from a transmission device at a broadcast station that is not shown. A transmission parameter interpretation unit acquires band information indicating a “no signal” band contained in transmitted control information. An interference rejection filter unit performs filtering at least when a signal with a level higher than a predetermined level is detected on the basis of the band information from the transmission parameter interpretation unit. The disclosed technology can be applied to a reception device that receives OFDM signals, for example.
    • 本技术涉及当已知没有数据被发送的频带上的信息时,能够提高接收性能的接收装置,接收方法及其程序。 接收装置接收从未示出的广播电台从发送装置发送的OFDM信号的广播波。 传输参数解释单元获取表示发送控制信息中包含的“无信号”频带的频带信息。 至少当基于来自传输参数解释单元的频带信息检测到具有高于预定电平的信号的信号时,干扰抑制滤波器单元执行滤波。 所公开的技术可以应用于例如接收OFDM信号的接收装置。

    • The present technology relates to a receiving device, a receiving method, a program, and a receiving system which may improve reception performance in the case of receiving a signal with a variable frequency band. A receiving device according to an embodiment of the present technology includes a demodulation unit configured to convert a received signal to a baseband signal in the case where a first frequency differs from a second frequency, wherein the first frequency is a center frequency in a band of the received signal, the second frequency is a center frequency in a band of a desired signal included in a part of the band of the received signal, and a DC component of the baseband signal is to be a frequency in the vicinity of the second frequency. The present technology may be applied to a receiver which receives an OFDM signal of DVB-C2.

    • A phenolic foam is made by foaming and curing a foamable phenolic resin composition that comprises a phenolic resin, a blowing agent, an acid catalyst and an inorganic filler. The blowing agent comprises a blend of chlorinated aliphatic hydrocarbon containing 2 to 5 carbon atoms and an aliphatic hydrocarbon containing from 3 to 6 carbon atoms mixed in a ratio of 60/40 to 5/5 parts by weight. The inorganic filler is at least one selected from a metal hydroxide, a metal oxide, a metal carbonate and a metal powder. The phenolic foam has a pH of 5 or more and a water uptake less than 1 kg/m2. A phenolic foam with a higher pH value compared with conventional phenolic foam reduces corrosion risk when in contact with metallic materials. The phenolic foam maintains excellent long-term stable thermal insulation performance, low water uptake and fire resistance performance and by using the said blowing agent, does not harm the environment as an ozone or global warming depleting material.
