On the occasion of the completion of MBS Broadcast Complex in Osaka City, we made up a sophisticated SHF network. We developed and installed a multi-band developments let us to receive/transmit three same polarity SHF waves within 10-13 GHz which are given to MBS in one route. Without any trouble for a year in operation, we have confirmed usefulness of these developments.

NHK Osaka Regional Headquarters renewed a helicopter system on December 1991. This system equips a camera control system with three-axes gyrostabilizer, two transmitters which can be operated simultaneously and a direction find for a microwave reciever. Therefore it can offer fineand stabilized Pictures on three road-races held in Kyoto and Siga Pref. in a year. we introduce this system used for daily news and outside broadcasting.

Recently, in the routine work of the newscasting-department, we are required to improve its efficiency and share the materials for going on the air. On the other hands, in the actual operations, we often required quick-change of the order for the news items, and reduce our efforts for the operation. Then we developed new computer system, which intends to unify from gathering informations to going on the air, that if from making-reports, news-gathering writing-Cuesheets to Sub-control. At the same time, we developed the control method for Bata-cart, Electric-telopper, Video-filling machine. Here we hope to make a brief introduction mainly on The One-touch Control System.

CCD camera are now getting popular in broadcasting use. The improvement of CCD technique has resulted smaller smear and less FPN. But higher picture quality is needed in producing dramas, so more excellent CCD camera characteristics are required.

This equipment which is connected with a digital recorder, detects automatically any errors of sound signal while recording. Therefore this equipment will make sound engineers free from monitoring operations of a digital recorder. The bit errors of the digital signal recorded on the magnetic tapes are the most frequent troubles while digital recording. This equipment records the bit errors condition automatically. In case of recording troubles, it shows the information on its display and also inform with a voice. And in order to detect any general troubles of recording, it compares input signal and output signal to find out the lack of signal and the level difference. In addition, the control of a digital recorder is automatic and also the operation of this equipment is easy. Regardless of the video or the sound, it will be possible to apply this equipment to all kinds of digital recorder. Therefore this will play an important part in quality control and maintenance of the radio and television program.
