    摘要： The OD servers, encoders, NOD servers and CPUs supply voice data, character data and remote control data together with the control information. A transmitter modulates the control information and voice data, etc. by the QPSK modulation method. An infrared ray emitter outputs the modulated infrared ray depending on the modulated signal. A receiving apparatus reproduces acoustic signal from the modulated infrared ray and displays characters and also transmits the signal corresponding to the remote control data to the transmitting apparatus with the infrared ray. An infrared ray detector receives the modulated infrared ray output from the receiving apparatus. Thereby, with this system, the signal, required by the receiving side or suitable for the condition of the receiving side, supplied through many channels can be transmitted without any restriction on the wiring.

    摘要： A learning apparatus in which a memory contains a first plurality of data units and a second plurality of data units each of which is related to a unit of the first program. Switches are provided for switching between the first and second pluralities of data units and for switching between the units within the selected plurality. Reading means are provided for reading a designated unit of data from the memory, based on a signal from the operation switch, thus making it possible to access and reproduce any desired program or articles related to the program. In another embodiment, a control memory holds the addresses of the data units, and the reading means obtains the address of the selected data unit from the control memory and reads the data at that address. The apparatus is uniquely suited for audio teaching material, such as languages, but may be used with any information which may be organized into logically related units.

    摘要： The present invention provides a transmitting apparatus, a transmitting method, a receiving apparatus, a receiving method, and a transmitting and receiving system that allow the maximum waiting time for the beginning of a content to be shortened in a near-on-demand transmission.When the length of a content is denoted by L seconds, the number of channels on which the content is transmitted is denoted by K, and the beginning detecting time of the content on the reception side is denoted by λ, if L satisfies the relation of λ*(2K−1) (where L and K are contents), the beginning detecting time λ can be decreased to L/(2K−1) against L/K as the conventional value.In reality, the transmission side divides L by the ratio of (2K−1) and repeatedly transmits each divided portion (section) on a discrete channel. The reception side connects each divided-portion (section) transmitted on each channel through a buffer memory, with which the maximum waiting time of the minimum divided portion (section) placed at the beginning of the content is used.

    摘要： Formerly, an individual communication operation was repeated between a dedicated terminal apparatus and other terminal apparatuses. Therefore, an extremely wide transmission band was required depending on the number of terminal apparatuses. The present invention transmits significant data unidirectionally among a plurality of terminal apparatuses and causes a terminal apparatus at the downstream end of a transmission path to collect the significant data. Each terminal apparatus includes a data detection section for detecting whether or not significant data written at another terminal apparatus located toward the upstream side of the transmission path is received, and also includes a data selection section for transferring the significant data as is to a downstream terminal apparatus when the reception of the significant data is detected or outputting significant data generated within the terminal apparatus to a downstream terminal apparatus when the reception of the significant data is not detected.
