Installation Details

The stadium's broadcast system was updated to Full-HD.

The Nagoya Keirin Stadium, which opened in 1949, holds cycle races and sells betting tickets both for its own races and races at other cycling tracks. In November 2014, the stadium upgraded its indoor broadcasting system to a Full-HD system. Durable Panasonic LCD displays were selected for outdoor installation.


Displays are installed under the eaves. The surrounding area is very bright on clear days, but the images are constantly sharp and clear.

The weather resistance of durable LCD displays was highly evaluated, leading to their outdoor installation use.

A wide range of information, including betting odds and race results as well as live, high-speed race images, are displayed at the stadium. Until now, CRT displays were used to show this information, but they were all upgraded to consumer-type LCD TVs with Full-HD compatibility.
However, the displays, which are installed at the outdoor ticket counters, must provide a high level of durability against wind and rain, and offer clear legibility even under bright sunlight conditions. These were difficult requirements for consumer-type TVs.

TH-47LFX6N displays were proposed because they offer the following features:

  • IP55 equivalent levels of dustproof and water-resistant performance, allowing outdoor installation without requiring any special casing.
  • High-brightness performance to display clear images even under bright outdoor conditions.
  • An Outdoor mode that enables stable operation in outdoor environments, under hot summer and cold winter conditions.
  • Aluminum cabinets that resist corrosion and rust.

The performance was demonstrated using actual TH-47LFX6N displays, leading to the installation of 12 units for outdoor use.


Water-resistant performance was required for outdoor installation. Durable LCD displays are ideal because their wide operating temperature range withstands temperature changes.

System Details

Stadium broadcasting system built for multi-channel, long-distance distribution.

The Nagoya Keirin Stadium required a multi-channel, long-distance distribution system to meet the following conditions. For this purpose a stadium broadcasting system was built using the same method as a CATV system.

  • Broadcasting over a distance of up to 300-400 meters was required between the Video Control Center and the displays.
  • A wide range of information needed to be presented, including betting odds, live race images, and race results. (Example: There are 7 ticket types, making a total of 783 combinations that needed to be displayed.)
  • Approximately 130 displays needed to be operated, and precise content had to be displayed at each location according to a preset schedule.

Text information on betting odds and race results, live race images, and other content were each assigned a channel number and this data was converted to RF signals by an ODFM modulator. Coaxial cables were used to distribute the signals inside the stadium. External tuners were connected to the displays installed outdoors, and the received RF signals were demodulated to HDMI images and displayed. The video content was switched by sending operating signals from the Video Control Center to the tuners, so information could be smoothly presented to the viewers.

Linking to Race Action for Various Information

Display content examples: 1Betting odds (the plate on the top of the display is a guide to the type of tickets displayed) 2Notification of the end of betting 3Live race images 4Race results. This content switches to match the race schedule. When a race ends, the display starts again from 1.
