摘要： PROBLEM TO BE SOLVED: To provide an emergency broadcasting system which can broadcast a current broadcasting by normal broadcasting and an emergency broadcasting simultaneously without a sense of discomfort, making smooth broadcasting available without any interruption of currently viewed program.
SOLUTION: The emergency broadcasting system is equipped with a weight adjustment means 110 for adjusting the weights of three signals, that is, an L channel sound signal SL from a sound source 10L for L channel, an R channel sound signal SR from a sound source 10R for R channel, and an emergency sound signal SE from a sound source 10E for emergency broadcasting; and an emergency sound mixing switching means 130 which switches between mixing and unmixing of a weight-adjusted emergency sound signal SEa into weight-adjusted L channel sound signal SLa and R channel sound signal SRa. The switching operation of the switching means 130 is controlled by a system controller 120.

摘要： PROBLEM TO BE SOLVED: To attain the stabilization of reception by dividing a stereo sound signal to a mobile body into left and right groups and transmitting them with a time difference to decrease the probability for left and right groups to simultaneously turn into reception interruption. SOLUTION: On the side of transmission, the input signal of right channel is delayed in a prescribed packet length by a delay circuit and transmitted while being multiplexed with a left channel. On the side of reception, a received radio wave is demodulated by a radio reception part 15 and demultiplexed into left and right channel signals 502 and 501 by a demultiplexing part 16, and the left channel signal 502 is delayed in a prescribed packet length by a delay part 50 and inputted to a discrimination part 51 after left and right packets are made coincident. The discrimination part 51 sends a result signal 504, which discriminates whether the respective packets are normal or not, to a switching part 52 and supplies left and right stereo digital signals 503 and 501 through output signal lines 506 and 505 to a decoding part 17 based on a prescribed algorithm. When only one of left and right channels is received, for example, the channel is outputted to both speakers.

摘要： PURPOSE: To improve the SN ratio by switching the signal paths so that one stream is inputted to two D/A converters and the outputs of these coverters are merged to be amplified by a LPF amplifier. CONSTITUTION: The L- and R-channel outputs of the D/A converter 25 are supplied to a mixing circuit 33 through the LPF amplifiers 29, 30 and the L- and R channel outputs from the D/A converter 26 are supplied to the mixing circuit 33 through the LPF amplifiers 31, 32. By receiving voice switching signal E, the mixing circuit 33 mixes the voice signals inputted from the LPF amplifiers 29, 31 with the outputs of the LPF amplifiers 30, 32 for each channel and outputs the respective mixed signals to the L-channel output terminal, 34, and the R-channel output terminal 35.

摘要： PURPOSE:To provide the acoustic reproduction device preventing deterioration in the S/N and increase in power consumption when left and right surround speakers output 2-channel surround signals from an audio signal sent in the radio system. CONSTITUTION:Audio signals L, R from a video tape recorder 1 are converted into a difference signal (L-R) by a radio transmitter 7 and also into a monaural radio signal M(L-R) and the result is sent to a radio receiver 8 as a radio wave. The radio receiver 8 receives the radio signal M(L-R) and converts it into left right difference signal (L-R) to generate 1st and 2nd delay difference signals phi1(L-R) and phi2(L-R) and the result is sounded out from left right surround speakers 9L, 9R. Thus, while the deterioration in the S/N and increase in power consumption is prevented in the case of transmission by the radio system, two channel surround signals are outputted to the left/right surround speakers arranged at the back side of the listener.
