Abstract: 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.

Abstract: Time slice transmission methods transmit data in bursts, thus creating a delay until playback of a service can begin when changing the service and therefore preventing smooth zapping. To solve this problem, a first stream used for burst transmission of packet sets and a second stream for continuously transmitting packets at a speed determined according to the transmission rate required for a particular service are multiplexed and transmitted. The content is reproduced using the continuously transmitted second stream during zapping, and the first stream transmitted in bursts is reproduced after zapping ends.

Abstract: A portable terminal includes a receiver, a barcode former configured to form barcodes and a display. The barcode former forms a barcode from the data received by the receiver and the display displays the formed barcode.

Abstract: A digital broadcast receiving apparatus, which has a receiving circuit for receiving a transmitted high frequency signal of a plurality of time division multiplexed programs, includes a circuit for selecting a better receiving characteristic condition while a desired program is not received.

Abstract: Disclosed is an OFDM signal receiving apparatus for diversity reception, with a plurality of antennas, of an OFDM signal containing Y sub-carriers, where 2X?1<Y<2X and X>1. The OFDM signal receiving apparatus includes a plurality of receiving systems, and a diversity processing unit connected to the receiving systems and fed with sequences of data on sub-carriers demodulated by the respective receiving systems. At least one of the receiving systems includes an FFT circuit for Fast Fourier transforming, in parallel, only a sequence of data on 2Z sub-carriers contained in the OFDM signal received with a corresponding antenna, where X>Z. The diversity processing unit performs a diversity process on sequences of data on sub-carriers, out of all the Y sub-carries, redundantly demodulated.

Abstract: In communication transmitting a first stream (intermittent data portion) for burst transmission of packet sets and a second stream (continuous data portion) for transmitting packets at a speed determined by the transmission rate required for the service, the second stream related to the selected service is received and reproduced for the selected service when a service is selected until intermittent data transmitted in the first stream can be received, and reception and playback of the first stream begins when transmission of the intermittent data for the selected service in the first stream begins.
