The annual NBA All-Star Game is about to be held. Fans can watch live videos on their computers, tablets and mobile phones. The development of technologies such as VR, AR has given us another step in the future of NBA live broadcast. Let me review and look at different NBA live broadcast methods.
Text Live
NBA mobile live broadcast is related to the mobile network speed and mobile phone performance. In the era of , the mainstream mobile phone live broadcast is text live broadcast. Text live broadcast refers to commentators transferring the live performance of the competition to the audience in text. This method saves traffic and can be qualified for 2G network speed. The requirements for mobile phones are also very low, as long as they are smart phones.
Now live graphic broadcasts still exist on the platform without NBA broadcasting rights
Later, live graphic broadcasts were released. Live text broadcasts are live text broadcasts with pictures. Text accounts for the main point, and pictures appear occasionally. Before the era of
video live broadcast
4G, there was live video broadcast on the computer. At that time, some third-party mobile APPs could even provide live broadcasts. However, the picture quality is poor, the traffic is expensive, and the experience is not good.
On December 4, 2013, the Ministry of Industry and Information Technology issued
Use Tencent Sports mobile client to watch NBA live broadcasts, and the live broadcast has added the unique elements of China's online live broadcast
Tencent NBA adopts the US "NBA League Pass" service to provide fans with NBA high-definition video live broadcasts. If you pay to become a member, fans can also enjoy 1080P clarity, Chinese-English commentary switching, multi-camera switching and casual viewing of all games.
Tencent NBA membership and live streaming without traffic service
Live streaming quality has improved, and network problems must be solved. First of all, the 4G network speed is fully capable of 1080P live video broadcast. Secondly, Tencent provides China Unicom King Card services to NBA Live. This service allows users to watch live videos without traffic, making it a reality to enjoy competitions anytime, anywhere.
VR live broadcast
VR is the next development point after the "mobile" of NBA live broadcast. Although has no VR live broadcast in China, including this season, the NBA has jointly provided VR live broadcast for two seasons with NextVR.
NBA official website VR live broadcast introduction
On October 27, 2016, NextVR used professional VR shooting configurations with 8 cameras to conduct the first VR sports event live broadcast in history. Since then, NBA's VR live broadcast has become more and more perfect. Today, NBA VR live broadcast supports head-mounted VR devices such as Samsung Gear VR, Sony PS VR, Google Daydream View and Windows MR.
NBA League Pass users can enjoy VR live broadcast and video highlights after installing the "NextVR" APP on any of the above devices.
Users who have not purchased NBA League Pass can also watch VR live broadcasts through TNT TV service. TNT's VR event live broadcast was brought by the NBA, Intel and Turner Sports' three-defense cooperation. TNT VR live streaming only supports Samsung Gear VR and Google Daydream View.
Netizens use Samsung Gear VR to experience NBA VR live
At present, I have not experienced NBA VR live
, but according to the descriptions of foreign netizens, I have summarized several characteristics of current NBA VR:
has a strong sense of presence.
has high clarity, such as seeing the player's shoelaces clearly.
viewing angle is slightly smaller than 180 degrees. The picture outside of 180 degrees is not a competition picture, but various competition data.
Because the viewing angle is not large enough, the broadcaster needs to switch the camera position to let the audience see every corner of the field. The broadcaster's lens cutting ability is very high.
sound effects are average, and the immersion level is not as good as the picture.
You can't watch mobile phones at any time when watching VR live broadcasts. Many people are a habit of watching games by browsing their phones to relax, but they cannot see the phone when wearing VR devices, which is not convenient enough.
has low popularity and high threshold for use.
AR live broadcast?
Last month, the NBA expanded its cooperation with wireless operator Verizon. will work on new forms of sports content, including AR and VR based on 5G networks.
AR example
If the broadcast can correctly move the AR content to the live broadcast screen, the fans' viewing experience will be greatly improved. AR can not only be integrated into VR live broadcast, but also into ordinary video live broadcast. The combination of ordinary video live broadcast + AR is more friendly than VR live broadcast, because VR devices are not cheap, and there are also limited areas for VR live broadcast. , so AR live broadcasts will have a larger audience in the short term.
Conclusion
NBA live broadcast is still in its infancy, but it has realized "watch the game if you don't go to the scene". Realizing an immersive feeling will be the next stage. VR and AR will play irreplaceable roles in it.
