At present, the traditional broadcast and television media industry is brewing a brand-new change due to the introduction of new technologies such as TD-LTE, which is faster and more time-sensitive. And the mobile high-definition instant camera and instant messaging service that has been adopted in the Haixinsha torch relay process of the Guangzhou Asian Games on November 9 is a microcosm of this great change.
Mobile HD instant shooting is one of the most representative applications that show the advantages of TD-LTE's high bandwidth and mobility, and the transmission effect of TD-LTE is completely comparable to traditional broadcast TV signal transmission methods, such as satellite , Microwave, etc. On the one hand, the high bandwidth characteristics of TD-LTE can fully meet the needs of uploading high-definition video signals. On the other hand, based on the mobility advantages of TD-LTE, media interviews can easily achieve mobility. Only a small TD-LTE terminal needs to be added to the professional camera, and the information obtained during the interview can be transmitted to the broadcast center in real time. There is no need for the transfer of satellite communication vehicles, and the speed and timeliness of live TV broadcasts are therefore. It was enhanced.
In the life delivery of the Guangdong Asian Games on November 9, Guangdong TV station used TD-LTE high-definition instant shooting for live broadcast for the first time, and the effect was amazing.
Mobile high-definition instant shooting, as the most dazzling one of the top ten applications displayed in the TD-LTE demonstration network of the Guangzhou Asian Games, has created TD-LTE since the construction of the demonstration network, used in the process of major activities " "The first battle".
Under the mobile high-definition camera-and-transmission service, in order to ensure the quality of live TV, the transmission of the image not only requires real-time, but also must be clear and smooth, which not only raises high bandwidth requirements for the TD-LTE network, especially in the uplink, Correspondingly, reliability requirements were also put forward, and the TD-LTE Guangzhou Demo Network delivered a satisfactory answer in real-life applications. During the Asian Games torch relay, Guangdong Mobile teamed up with Guangdong TV Station, based on the TD-LTE demonstration network provided by Huawei, to formally apply the TD-LTE high-definition instant camera and pass-through service to the TV through a "TD-LTE mobile media interview vehicle" Live broadcast, real-time delivery of high-definition video signals. After watching the live TV broadcast, the relevant leaders of Guangdong TV Station could not wait to give telephone feedback: "5 live broadcast points, using satellite, microwave and LTE three different transmission technologies, of which LTE live broadcast is the best!" It is reported that both success After completing the live TV broadcast task of the Asian Games torch relay, the TD-LTE high-definition instant video transmission service has also undertaken the work of live broadcast connection in subsequent competitions, and is constantly winning the recognition of the traditional media industry. For example, before the opening of the Asian Games, CCTV has visited the China Mobile South Base for the instant camera business that it is concerned about.
1. In front of the China Mobile Asian Games Hall, staff members are standing on a mobile media interview vehicle to shoot, and the pictures taken are also displayed on the large screen behind them in real time.
2. Only need to add a small TD-LTE terminal to the professional camera to realize the high-definition instant shooting and transmission service.
In order to allow more people to fully experience the revolutionary changes brought about by this new application, Guangdong Mobile has set up a mobile high-definition instant shooting experience area in the Asian Games Hall and South Base. During the Expo, this business is still only in the stage of visiting. The progress made by the TD-LTE industry in the past few months can be seen. In the Asian Games Hall of China Mobile, the reporter personally played the role of a "new generation" live TV photographer armed with TD-LTE, a high-tech. After boarding the mobile media interview car, you can get rid of the shackles of the cable and freely find the best shooting location and angle. The high-definition pictures taken by Tianhe Sports Center are also displayed in real time in China Mobile On the large screen outside the Asian Games Hall, the speed and convenience of the whole process is really amazing.
