According to the on-site information service reflected by the audience, after further analysis, it is found that the audience in China like and rely on the information provided by the on-site commentary to a great extent. However, in the past, due to the lack of information transmission capacity of public broadcasting equipment, it was unable to resist the huge roar of the live racing engine, so a considerable number of viewers could not get clear explanation information. They can only face the racing cars speeding by on the track in front of them, but they know nothing about the rankings, team driver information, tactics or what is happening in other areas of the track. In order to meet the audience's needs and show their commitment to humanized service, the idea of developing China Grand Prix headphones (F 1) and cooperating with high-level on-site commentators to provide on-site information services for the audience emerged at the historic event. Although there is no similar experience in other F 1 events in the world, long-term events actively contact professional digital product manufacturers to study and explore the feasibility of developing F 1 dedicated headphones. The management of Jiushi Tournament believes that F 1 has accumulated decades of history in Europe and America and has formed a mature market. However, F 1 was only held in China for just four years. Therefore, it is necessary to open up new ideas and develop new service models to make it easier for the audience to understand the racing culture and enhance the experience. After contacting with professional digital manufacturers and using the existing products for simulation testing, Nine Lions Championship reached a cooperation intention with Patriots to develop F 1 dedicated headphones to provide technical support for improving information services. This earphone developed by Patriot will adopt active noise reduction technology. By receiving and analyzing the frequency of external noise through an audio receiver (such as a micro microphone) and an anti-noise output chip, waves with opposite frequencies will be generated, which will cancel each other out and finally achieve the purpose of shielding noise. At the same time, this headset will also integrate wireless broadcast receiving technology to listen to the live commentary information of the event. In order to ensure the listening quality, two special radio channels have been specially applied for long-term events, and relevant transmission facilities have been built on the field to ensure that the live commentary signals can cover the whole audience (including straw mats). Patriot said that there are still some technical problems to be solved, including the contradiction between the weight and function of headphones, the contradiction between compactness and comfort, and the contradiction between advanced technology and cost control. More importantly, active noise reduction technology was mainly used in ordinary outdoor environment before, but it has never been used in the engine roar of F 1, so it is necessary to optimize the structure and circuit to ensure the noise reduction effect. There are still more than two months before the F 1 China Grand Prix. Patriots said that although time is tight, they are confident to complete the research and development work before the grand prix and dedicate a perfect work to fans. The event also announced the way for fans to participate in the event: interested fans can give suggestions for the ideal F 1 special headphones through www.racing-china.com, official website, and the event will provide the enthusiastic fans with official posters of the 2008 F 1 China Grand Prix and audition tickets for special headphones. Improving information service, enhancing on-site experience, and high-tech special headphones are measures to comprehensively improve on-site information service. On-site commentary, because the previous commentary service was mainly aimed at the audience in the stands, the commentary perspective was limited. This year, a brand-new commentary service will be launched to provide real-time commentary from the perspective of each stand, so as to ensure that the audience can fully understand the real-time situation of the whole stadium no matter which stand they are in. In addition, through headphones, the audience can also listen to all kinds of service information and off-site activities of the whole stadium, including departure time and place, catering types and supply locations, shopping areas, various brand display activities, live exhibitions and performances, drivers' signatures and interactive activities with fans, etc.
