On July 18, the new version of "News Network" was launched. In this revision, the title is "completely upgraded", and the familiar background music and opening animation are still used. The main vision retains the world earth and starry sky background, but fine-tuned fonts, images, colors, etc. In addition, the biggest change in the title after the revision is that the 16:9 HD title is enabled for the first time, realizing the full HD production and broadcasting of current affairs news. What is full HD production and broadcasting? Why should the picture be adjusted to 16:9 composition?
Full HD news production and broadcasting, clear picture quality and better impression
The revision of "News Network" focuses on upgrading the "Full HD News Production and Broadcasting", which is an important step in the high-definition upgrade of the news programs of the Radio and Television General Station.
Recently, the State Administration of Radio and Television requested that from June 15th, all localities start the shutdown of the central program terrestrial analog TV signal and complete it before August 31. If there are special circumstances, it will be completed before December 31, 2020 after approval by the SARFT. Shut down.
Analog TV is no longer the mainstream of home TV. According to data provided by the State Administration of Radio, Film and Television, as of the end of June 2019, there were a total of 216 million cable TV users across the country, including 203 million digital TV users, with a digitization rate of 93.98%.

The picture shows that compared with analog TV, digital TV has a good reception effect, with high image quality, large program capacity and good sound effects. The quality of the TV image and sound received at the receiving end is very close to the studio level. From the above data and comparison, it can be seen that the audience's demand for high-definition and high-quality images is increasing, and the realization of full HD news production and broadcasting is imminent. This revision is in line with the development trend of radio and television and the audience's viewing needs.
16:9 composition to enhance visual presentation
The screen aspect ratio of "News Network", which was launched on July 18, has been changed from 4:3 to 16:9, the word "HD" is displayed in the upper right corner of the screen, and the host’s screen scene and seat spacing have been fine-tuned to enrich Lens language and picture information.

The superiority of 16:9 HD production and broadcasting is not only reflected in the clearer picture quality, but also in the composition. The traditional 4:3 standard definition composition has great limitations. It has very strict requirements on the distance between the stations and the scene of the picture. If you are not careful, accidents such as "head stuck" and "person separation" may occur.
Compared with 16:9, 4:3 standard-definition composition is more limited in viewfinder. When using large panoramas to explain the background and atmosphere of the environment, the amount of information that can be reflected is limited, which can easily cause scene cutting or incomplete lens language. Wait for the situation.

In addition, as modern living rooms continue to grow, the user market's demand for large-screen digital TVs is also increasing, so many TV screens are developing to widescreens. Due to the different ratios, there are black borders on both sides of the title and content of "News Network" currently displayed on many TVs, which greatly reduces the display effect. After the revision, the 16:9 widescreen ratio is more in line with the visual habits of the human eye. Being able to adapt to the needs of new TVs and adopting 16:9 high-definition composition is the current trend of mainstream TV media in the world.
