"2003, standing in the third pole" large-scale TV live technology solution

Beijing time at 13:40 on May 21, 2003, is destined to become a memorable moment in the history of Chinese television development. At this moment, the 2003 Chinese team members of the Everest Mountaineering team held up a five-star red flag on the peak of Mount Everest at an altitude of 8,848.13 meters and was clearly presented to all Chinese people through the TV screen.

This is the first time that humans have been broadcasting the Everest summit. During the 11-day live coverage, Beijing, Everest base camp, campsite in front, and mountain video direct broadcast programs reached 206 hours, a new breakthrough in the history of CCTV broadcast. The successful completion of the live broadcast is not only an extreme challenge for television workers and various equipment in harsh environments, but also an unprecedented history of the development of China’s television industry and even the world media industry.

The live broadcast of CCTV has created nine “firsts”:
The first time live to climb Mount Everest;
First set up a satellite ground station at the 6500m forward camp;
For the first time in 11 days, live mountaineering in Mount Everest;
The first time from 7028 meters north camp to 6500 meters forward camp laying optical cable;
The first long-term shooting of the 6500-meter marching camp climbers' activities;
The first time live to climb the North Cliff Ice Wall;
Send the live broadcast signal from the second step for the first time;
The first one-hour continuous live broadcast from the peak of Everest;
The first installation of a wireless intercom system covers the entire climbing route. We specifically collected related live technology solutions and live broadcast sentiments, organized into "extreme broadcast" topics, for television broadcast counterparts referencing.

"Why live, because the Warriors are in the mountains!"


The "Zhumu" in the Tibetan "Qomolangma" is the meaning of the goddess, "Rangma" is the third, "Qomolangma" means "the third goddess." Fifty years ago, New Zealander Edmundo Hillary and his partner, the Nepali Sherpa Tenzin, created history on May 29th, becoming the first holy third goddess of humanity. "The hero who left footprints on the top of the hill. To commemorate the 50th anniversary of the summit of Mount Everest, the China Mountaineering Association organized the China Everest Mountaineering Team to perform a monumental climb to Mount Everest.

In order to comprehensively and accurately report the event in a timely manner, CCTV has planned a large-scale live special program of "2003, Standing on the Third Pole" to carry out a full-range simultaneous telecast on the Chinese mountaineering team's process of climbing Mount Everest. The Everest, which is known as the third pole of the earth, broadcasts live on TV. The technical difficulty is so great that many unknown factors and long time span are unprecedented in the history of CCTV.


In the world radio and television records, it is also an innovation. From 11th to 21st of May, 11 days of live TV broadcasts made the audience fully feel the charm of modern mountaineering and the spirit of China's mountaineering athletes who feared the hardships and dangers, bravely climbed the heights, and television workers to overcome difficulties and be scientific and pragmatic. In this large-scale live broadcast program, domestic and foreign media have commented that the success of this live broadcast is a brand-new breakthrough in the history of CCTV television broadcasting and is a severe challenge to the working limits of television workers and various devices in harsh environments. Is the history of the development of China's television industry, but also the world's media industry unprecedented history of a great creation.


The television broadcast on Everest is exceptional and unique, regardless of its uniqueness and challenge. Specifically, there are the following aspects:


First Everest terrain and climate


Mount Everest is located in the eastern section of the China-Nepal border. The northern slope is in the territory of China's Tibet and the southern slope is in Nepal. The entire mountain is in a giant pyramid, majestic, towering, and surrounded by extremely steep terrain, and the weather is changing rapidly. Everest is not only magnificent, but also magnificent. In the range of 20 kilometers around it, there are many peaks and mountains, and there are more than 40 peaks above 7000 meters above sea level.

The most famous are the Lhotse (8463 meters above sea level, the fourth highest point in the world) and the Zhuoqiu peak (7589 meters above sea level), 3 kilometers to the south, and the southeast is Macalulu (8463 meters above sea level, the fifth highest point in the world). The 3 km is Zhangzifeng with an altitude of 7543 meters, and the west is Nuzi (7855 meters) and Pemori (7145 meters). Here, a rugged landscape is formed around the peaks, the peaks and the waves.


This climb uses the traditional route of the northeastern ridge route. There are six mountaineering camps on the climbing route. The 5,100-meter base camp, the 1,500-meter-long camp 1, the 6,000-meter camp 2, and the 6,500-meter camp are also known as the advance camp. 7028 The No. 4 Camp is also known as the Beijiao Camp, the 7790m Camp No. 5, and the 8300m Camp No. 6 also known as the Assault Camp and the 8848m Mount Everest peak.


Base Camp is the general commander and general coordination and protection camp for climbing Everest. The forward camp is a frontline command and coordination camp for mountaineering. From the North Point camp, you can see almost all the climbing routes and camps, and you can see the forward camps down. Due to the obstruction of 7543 meters of Zhangzifeng, we can only see the height of 8,850 meters above the peak of Everest in the base camp. The distance from the base camp to the forward camp is approximately 18 kilometers. The base camp of the base camp is approximately 19 kilometers from the summit of the Mount Everest, and the forward camp is about 2 kilometers from the camp of Beidai. The north camp is about 6 kilometers from the camp. The terrain of the entire climbing route is complex, meandering, uneven and dangerous.


The climate in the Everest region is complex and changeable. Even within a day, it is often clear and snowy. The minimum temperature can reach minus 30 degrees. The maximum wind speed can reach 90 meters/second. Statistical analysis shows that, in mountain areas, the change in surface wind speed is greater than in plain areas, and the higher the altitude, the greater the change in wind speed.


The diurnal variation of surface wind speed at an altitude of 4,500 meters is 4.5 times the altitude of 1000 meters. At this altitude, the wind speed at 2 to 6 o'clock local time is 5.5 m/s higher than the average wind speed at night and in the morning. It is inferred that the diurnal variation of surface wind speed at an altitude of 6000 to 8000 meters is about 6 to 8 times the altitude of 1000 meters above sea level, that is, the wind speed in the afternoon is about 7.3 meters/second to 9.8 meters/second higher than the wind speed at night and in the morning.
