Digital virtual anchor ＂hold the audience＂! CCTV’s ＂C+ Moment of the Two Sessions＂ highlights the creativity of intellectual media.

　　The "two sessions" is a conference where the delegates put forward their opinions on politics, and the whole country gathers together to jointly start a new era and a new journey. The "two sessions" have always been the "battleground for military strategists" expressed by major media innovation and media integration. In this year’s media products of the NPC and CPPCC, CCTV’s "C+ Moment of the NPC and CPPCC" is particularly eye-catching. This special program uses virtual digital person Xiao C to interact with real people, and the innovative live broadcast of the combination of reality and reality can be described as "unique". Compared with the existing AI anchor, Xiao C not only achieves real-time motion capture and rendering, but also enables multiple systems to be seamlessly integrated. This not only makes "C+ Moment of the NPC and CPPCC" better among the media products of the NPC and CPPCC this year, but also makes the industry see more possibilities of "media+technology".

　　Technology Leading: Making Reality and Virtual "Seamless Interaction"

　　The current news production pattern is showing a kind of "transition": the production process dominated by people in the past is turning to man-machine collaboration, and the leading force of technology is becoming more and more obvious. The technical focus of "C+ Moment of the Two Sessions" is Xiao C, which is also the "technical element" created by the creative team. It is a core figure active in the center of virtual space and an "important hub" for the transfer of mainstream ideas and technologies.

　　In order to present the best effect in the live scene, "C+ Moment of the Two Sessions" comes up with a variety of hard-core technologies such as real-time face+motion capture, real-time rendering, deep learning, etc., trying to make Xiao C look more natural and beautiful. Among them, the key technology of "face+action" capture makes Xiao C interact smoothly with real people. During the live broadcast, Xiao C’s expression, body and clothing all show real, smooth and natural effects, and support real-time interaction with guests. The delay of expression and action is controlled in seconds. The small C in the live broadcast has high fidelity, rich facial expressions and flexible and smooth whole body movements, which increases the user’s sense of substitution, as if he were still a familiar "host" in the center of the screen to lead the audience to understand the focus issues, effectively realizing the seamless interaction between real people in the real world and small C in the digital world.

　　For Xiao C, she is no longer an "additional character" in traditional practice, but can easily control the audience and finish the program. From this point of view, "digital people" are no longer fragments and short-term presentations in the program, but have integrity, thus bringing viewers a stronger novel visual experience. "C+ Moment of the NPC and CPPCC" is not a pure "cutting-edge technology exhibition", but really makes digital virtual people play a key role in the expression of mainstream ideas.

　　In fact, it is not easy to run through the whole process of "digital people" in live programs, especially in such a serious and in-depth interview and dialogue program. However, CCTV’s "C+ Time of the Two Sessions" succeeded: Xiao C achieved real-time presentation and real-time expression, which was synchronized with the "live state" of the program. Without the help of any real host, Xiao C is the most beautiful protagonist in the center of the stage.

　　Of course, we can find from the complex underlying technology behind C: the cutting-edge technology has achieved extensive and effective infiltration in the news production and broadcasting process, and has produced the integration efficiency of "1+1>2". Behind this trend is the increasingly sophisticated practice of intelligent media technology. The leading of technology has changed the traditional live broadcast program structure, and also made the serious content production such as "NPC and CPPCC" have a "sense of vitality" and "affinity" to attract more young users to watch.

　　Artistic sense: Make the interview full of "sense of science and technology" and "sense of the future"

　　The three issues of "C+ Moment of the NPC and CPPCC" all focus on the hot topics of the NPC and CPPCC, inviting people from relevant fields to discuss together and gain insight into the development of the times from microscopic details. In the program, there is almost no difference between Xiao C and the real host, and together with the guests present, he completed an innovative small-screen live broadcast.

　　It is worth noting that the space design of program recording: although in a virtual scene, the program has created a virtual studio space with a "sense of science and technology". Being in this environment, you obviously have a stronger sense of the future, which also provides a visual consistency for the guests to talk about the future development, and also adds a lot of artistic atmosphere to the whole interview program.

　　Behind it is the strong support of technology: the technical team of "C+ Moment of the Two Sessions" continuously optimizes the real-time rendering effect. In order to ensure the smooth live broadcast effect, the virtual scene in the real-time rendering engine is continuously optimized in the design process, which realizes the win-win of artistic effect and fluency of the virtual picture during live broadcast, which not only maintains the perfect artistic presentation, but also maintains the high frame rate of real-time image output.

　　As a result, C+ Moment of the NPC and CPPCC has achieved the integration of multiple systems: the digital person C, the invited guests in reality and the virtual scene built together, forming a virtual scene with great visual penetration. It is understood that in order to achieve this goal, "C+ Moment of the Two Sessions" has realized the perfect integration of "virtual+real-life studio" with the help of a high-precision, automatic tracking 4K ultra-high-definition pan-tilt camera and real-time matting technology of sub-pixel details. At the same time, in this live broadcast, the push-pull and swing of the camera in the virtual scene and the camera in the real world are driven in real time, presenting users with seamless lighting and lighting effects, achieving high-quality program broadcast effects and presenting more attractive "art" in a "technical" way.

　　The C+ Moment of the NPC and CPPCC pays more attention to the visual texture and viewing experience like a movie in the scene construction, which also creates a possibility for the combination of mainstream content and picture aesthetics: talk shows can also be "different" in visual expression, taking into account "ideological" and "artistic". "artistry" is no longer just an exclusive product of literary and artistic creation, but news programs can also be owned.

　　Frontier thinking: continuously stimulating the "creativity" of intellectual media

　　With the rapid penetration of intelligent technology into the texture of the media industry, the two sessions in the past two years have also become a time node for the concentrated appearance of various "black technologies". The "show" of cutting-edge technology not only makes us feel the vigorous tension of the development of smart media, but also witnesses the further maturity of "media+technology".

　　In fact, during the two sessions last year, CCTV’s Little C Digital Virtual Xiaobian made its debut. It showed people with a refreshing and capable short hair and high value, and played the role of a reporter in the "C+ Detective Series Live Programs of the two sessions", and made "cloud connection" with NPC deputies such as Liang Qianjuan, Ma Huijuan and Wu Duanhua. This innovation not only solved the urgent need of cloud interview during the epidemic, but also constructed a more interesting interview scene. This model organically combines digital human technology and cloud connection technology by using the latest achievements of AI technology, and is an innovative application of CCTV in major current affairs reporting.

　　The "Long March Road" of the intellectual media should never be once and for all, but requires a lasting enthusiasm for construction. The use of small C this year can be regarded as the continuation and upgrade of the technological achievements of digital virtual human last year. In fact, in the past two years, we can always see the diversified innovative practice of CCTV. From 2020′ s "Answering Questions, Opening to Traffic with Wisdom" to attract users to accept and perceive information in the gamification scene of thinking, talking and hands-on, to 2021′ s "AI Assistant takes you into the ministerial channel" to move the scene of the ministerial channel of the two sessions into the mobile phone; From the first appearance of Xiao C in 2021′ s "C+ Reality Show Series" to the more mature application of "C+ Moment of the NPC and CPPCC" in 2022, CCTV has always adhered to the experience of "scientific and technological innovation" in current political reports accumulated in the content practice again and again, by injecting scientific and technological genes into the whole communication chain, the technology and content are truly combined, and then the "creativity" of intelligent media is continuously stimulated.

　　At the key node of the new mainstream media entering the critical period, CCTV is constantly exploring the process of "smart media path", and it is also accumulating useful experience and expanding the imagination space of future media!
