摘要： A transmission method of a digital broadcast, which is compatible with a DVB-T terrestrial digital broadcast system in Europe, saves a battery in a mobile terminal. Superframes in DVB-T are divided into units each including plural symbols so that an integer number of TS packets can be carried in each slot. At least one slot is used to transmit one service. Energy dispersion, Reed-Solomon coding, byte interleaving, convolutional coding, and time interleaving are applied to each service. When services for mobile terminal reception and services for fixed terminals are transmitted as the provided services, null packets may be transmitted before and after the slot carrying the mobile receiver service so that the fixed reception service and the mobile reception services are not mixed.

摘要： In a null symbol detection device, at the time of receiving a terrestrial digital broadcast, a null symbol can be stably detected even under a fading environment. A synchronous addition buffer group is provided subsequent to an amplitude detector so as to synchronously add an OFDM signal at a null symbol repetition period. A moving average processing unit performs a moving average operation upon synchronous addition data with the number of samples corresponding to a null symbol to output a moving average value. A transmission mode determining unit detects the minimum value among the moving average values normalized in a correction processing unit and compares levels of the minimum values to determine a reception mode. A null position detector generates a synchronous pulse at a null position.

摘要： An array microphone is a directional microphone having an improved directional characteric in which both the sensitivity and the sound pressure frequency response are uniform within the recording area and more particularly, the quality and level of sound remain unchanged. The array microphone includes a microphone array including a plurality of microphone units, and a two-dimensional filter for filtering an output of the microphone array in the dimensions of both time and space. When the two-dimensional filter is a digital filter and varied in its two-dimensional filter coefficient and sampling frequency, the array microphone serves as a variable directional microphone whose directional characteristic can be varied with the sound quality and level remaining unchanged throughout the recording area.
