摘要： PROBLEM TO BE SOLVED: To provide a method for displaying a transmission state, which can support a running operation of an information transmission system so as to make it more simple by recording information related to the running operation of the information transmission system.
SOLUTION: Transmission information transmitted by radio is received from a mobile body which moves on a course having a go-out route and a come-back route whose transmission state are different from each other. A distance value by which the mobile body moves is obtained from the received transmission information. Position information of the mobile body is generated on a map by converting the obtained distance value into information of latitude and longitude. A position marker which indicates a current position of the mobile body is displayed on the course; and at least one of a relative distance 1144 between mobile bodies of a plurality of the mobile bodies, a distance 1143 from the current position of the mobile body to a predetermined position, and an estimated moving time from the current position of the mobile body to the predetermined position is displayed.

摘要： PROBLEM TO BE SOLVED: To provide a digital video signal transmission system or the like for reducing a deterioration in image quality of SDTV signals in the case of mapping two SDTV signals on an HDTV screen image and transmitting the resulting signal through an MPEG compression process. SOLUTION: In mapping two SDTV sources A, B on the HDTV image screen, the sources A, B are vertically arranged and extended in a horizontal direction. It is known that the MPEG system generates a failure in the screen image from detailed part (high frequency component) of the screen image at compression. When the SDTV sources are extended on the screen image in the horizontal direction and mapped thereon, since the high frequency component is suppressed, the deterioration caused by the compression process of the MPEG system can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a digital terrestrial broadcasting relay transmission apparatus which makes relay transmission possible while avoiding multistage connection with a microwave network and maintaining signal quality.
SOLUTION: A digital terrestrial broadcast wave of a speicfic channel is selectively received at a tuner 12. A digital broadcast signal (TS, TMCC/AC) is demodulated from a received signal at a demodulation part 13. Then an error correction is applied by decoding parts 14 and 15 to restore CN deterioration and decode. After TOT rewriting in consideration of a loss time required for signal processing at a TOT rewriting processing part 16, time division multiplex is performed by a multiplexing processing part 17 to reconfigurate a TS broadcast signal and then transmit from a TTL transmission part 18 to a nextstage relay station by a TTL wave. By arranging such a relay transmittion apparatus as this for an intermediate relay station, TTL 2-stage relay is disolved while maintaining the signal quality.
