Television Reception Improvement Committee

Until around 1965, when television broadcasting began, reception conditions were relatively simple, and reception methods were extremely easy. However, recently, the increase in television channels (multi-directional, multi-channel), the coexistence of UV broadcasting, the introduction of color television, the use of two or more TVs per household, collective reception in housing complexes and apartments, poor reception due to building shadows, and the emergence of cable television have made reception conditions more complex, making it difficult to cope with the simple reception methods of the past. As a result,
　reception problems have increased, and there has been a growing demand from viewers for improved picture quality due to the introduction of color television.
　Therefore, organizations related to television reception, such as retailers, manufacturers, and NHK, have taken the lead in forming the Television Reception Improvement Committee. This committee aims to formulate a comprehensive reception system, from receiving antennas to receivers, that can be applied to the above-mentioned reception conditions, thereby improving the performance of reception-related equipment and promoting its widespread adoption to realize a good television reception environment and meet the demands of viewers.

Background to the establishment of the Television Reception Improvement Committee (from “30 Years of Progress”)

Main business overview and achievements

■ Improvement and standardization of receiving system equipment

　To improve the performance of various individual components required for assembling the receiving system, we promoted the following prototyping, improvement, and standardization in collaboration with related industries.

　Development of high-interference rejection televisions
　; prototyping of antennas for VHF ghosting reduction
　; development of high-performance coaxial cables; JIS standardization
　; development and standardization of various connectors (push-on type, C15 type, for BSCX).

(1) Antenna for ghosting improvement		(2) C15 type connector
(3) Study on a simple installation method for BS antennas

■ Standardization of the receiving system

　- Butterfly mark designation for receiving antennas and shared antenna equipment
　- Establishment of BS mark and BS digital mark systems for satellite broadcasting receiving equipment

(1) Butterfly mark

(2) BS mark

(3) BS Digital Mark

■ Training of receiving system engineers

　To simplify and streamline the installation methods for receiving antennas, home shared antenna systems, BS antennas, etc., and to meet the demands of the times, we conducted technical training courses nationwide in collaboration with the National Federation of Electrical Contractors and Electrical Contractors’ Associations to acquire new technologies and train and improve the skills of construction technicians.
　 In addition, we held various seminars throughout the country in cooperation with local television reception improvement committees to keep up with current trends.

　　 • Satellite broadcasting reception technology training course
　　 • Broadcasting reception technology training course for the digital age
　　 • BS digital seminar

■ Development and promotion of receiving systems

　Each year, a theme was set for activities such as inspecting poorly receiving urban shared antenna systems, inspecting antennas and shared antenna systems for improvement, and conducting reception campaigns in preparation for the introduction of BS satellite broadcasting. These activities were carried out nationwide in cooperation with local television reception improvement committees
　 . In addition, desirable reception systems were exhibited at events such as “CEATEC JAPAN,” “Good Living Show,” and “Housing Renovation Fair.”

■Basic activities such as various fact-finding surveys

　As foundational data for promoting various activities, we conducted various surveys according to their purpose, such as surveys of the actual conditions in multi-directional reception areas, surveys of the actual conditions of television reception equipment construction, and performance surveys of BS/UV home reception system equipment. We strived to understand the current situation and identify problems, and used this information to support various projects.

　　 • “Survey on improving the operability of remote control functions”
　　 • “Survey on the actual usage status of receiving system equipment”
　　 • “Survey on methods for interconnecting AV equipment”
　　 • “BS-IF joint receiving system technology survey”

■ Various awards for various activities

○ Recipients of the Broadcast Culture Foundation Award
　: In 1975, the antenna development group that succeeded in “making receiving antennas high-performance and miniaturized” received the Broadcast Culture Foundation Award, and in 1977, individuals received the award for “editing and publishing the TV Reception Reader Series” in recognition of their respective achievements.

○ Receiving the Minister of Posts and Telecommunications Award
　 On June 1, 1999, “Radio Wave Day,” the company was awarded the Minister of Posts and Telecommunications Award for “making a significant contribution to the advancement of broadcasting by improving the reception environment through the establishment and dissemination of broadcasting reception systems, and by striving to train reception engineers who can respond to the digital broadcasting era.”
