Last year’s discussion on the “Integrated Development of Traditional Media and New Media to Integrate†and the recent speech at the press media conference told us that no matter what kind of media, it is necessary to turn the requirements of guidance into guiding guidelines for the future work of radio and television. . The rapid development of network video will gradually standardize IP-based video distribution methods, and will be rapidly adopted by terrestrial digital television, cable television, IPTV and OTT, and accelerate the trend of media integration and integration; meanwhile, the trend of media convergence It will surely lead to the establishment of a unified media policy, evaluation and management system; the three technologies of immersive experience, HDR, 3D audio and AR/VR, will also be tested during the year.
1. The integration of media integration is the key to unified management. The establishment of a unified media policy, evaluation and management system is a general trend. In addition to further improving the traditional satellite, terrestrial and cable television monitoring and control, IPTV, Internet TV and mobile TV, including mobile Internet audio and video program client will be included in the unified supervision. The evaluation method of rating only can no longer meet the rapid development of media technology evaluation. Introduce new evaluation parameters, such as search start rate, search play rate and search play time ratio, to evaluate the program recommendation efficiency; attracting parameters such as positive coefficient, negative coefficient and search depth to evaluate the orientation will be the monitoring and supervision of technical development. the trend of.
2. IP-based video file formats, media distribution and distribution are quickly standardized and will be widely adopted by digital terrestrial television, cable TV, OTT and IPTV. HTML5, ISO media release description MPD, ISO media format BMFF, and delivery standard MPEG-DASH were successively standardized last year and adopted by US terrestrial digital TV ATSC 3.0, SCTE, and European ETSI. MPEG-DASH will also be the delivery standard for future OTTs. .
3. "TV +" or "Radio TV +" will be the main line for the development of broadcasting and television in the future. There are mainly two meanings: The first is to increase the service content of broadcasting and television, and to expand the service range of broadcasting and TV; to achieve this, it is necessary to adopt " "Internet", as soon as possible to achieve broadcasting and television technology, content, business, form, function and other aspects of the expansion of the Internet, and then do a good job of "Internet +"; second is the transformation and upgrading of broadcasting and TV, is to increase wisdom, to do smart broadcasting, improve Non-traditional radio and television services include e-government, e-commerce, tele-education, telemedicine, smart homes, smart industries, and smart city service levels, and comprehensively improve the dissemination, influence, and competitiveness of radio and television.
4. The development of cable television network from interoperability to further integration of network resources. At present, Internet TV has already achieved the one-stop service of using cloud technology to complete the production of programs and distributing them. It has also rapidly tapped into the broadcasting industry and even adopted cloud television directly. On the basis of nationwide network interconnection and interoperability, CATV will further integrate network, computing and storage resources including data centers and CDNs, and build a national or regional cloud distribution platform. Cable TV adopts cloud and virtual terminal technology to solve the problem of upgrading the original set-top box and non-uniformity of set-top boxes, and gradually adopts virtual set-top boxes or virtual gateways, thereby realizing a battle-based service of cable cloud distribution platforms to users.
5. Local television stations have adopted cloud and big data technologies to integrate computing, storage, and network resources. The popularity of the cloud is not just the adoption of cloud technology, but the transformation of the entire industry: regardless of the big platform, it is impossible for each TV station to establish its own cloud, whether it is to build the cloud or to cooperate with other cloud platform providers. . However, cloud platform providers are currently unable to meet the requirements of TV stations in terms of high-quality program video processing such as GPU and other cloud resources. Therefore, the integration of central, provincial, and local TV stations, and the establishment of certain radio and television networks by regions will be an inevitable trend. The use of a distributed cloud architecture between the stations and stations is actually a process of integrating resources within the stations. It integrates computing resources, network resources, and storage resources originally distributed between the stations and the stations. After virtualization, the implementation is realized. The unified scheduling, arrangement, management, and billing of image processing, transcoding, and packaging capabilities at the platform level will completely change the process of shooting, pre- and post-production and broadcast of original program production as well as production, broadcast, media assets, and monitoring. And security architecture. The entire ecosystem of the entire Taiwan, Taiwan, traditional media and new media will also undergo qualitative changes.
6. Network virtualization, software-defined networking and network function virtualization (NV/SDN/NFV) will be widely adopted. The widespread application of NV/SDN/NFV technology will trigger a wave of communications, mobile, cable TV, and intra-network transitions, and profoundly change the overall IT and communications architecture and relationships in the world. Network virtualization virtualizes the physical network into multiple application networks. Network function virtualization abstracts and moves network functions to the upper layers, further simplifying the network infrastructure. Software-defined networks separate the control and distribution functions of the data link layer. Functions such as management and service creation have been moved to orchestration and controllers. All of the aforementioned efforts will make traditional IT and communications more open, use common equipment, and reduce operating costs. At the same time, they will also face new security challenges.
7. The research and testing of the next generation of terrestrial digital television wireless standards in China will accelerate. The US terrestrial digital television wireless standard ATSC3.0 will enter the commercial phase this year. Both broadcast and broadband channels use IP and above protocols and can be delivered to multiple different platforms, which better solve the problems of mobile networks and wireless networks. relationship. The development and testing of China’s next-generation terrestrial digital television wireless network will enter the fast lane this year. Pilots will be piloted in several cities, focusing on the future relationship between broadcasting services and mobile Internet services, and the relationship between 4G/5G mobile networks and wireless networks. Relationship.
8. High Dynamic Range HDR Ultra HDTV will begin to land. At the end of last year, Europe announced the second phase of UHD-1 Phase 2 business requirements (UHD-1 Phase 2), which is divided into two nodes: Node A around high dynamic range, BT.2020 basic requirements and 10-bit sampling requirements to meet 2017 The initial business requirements; Node B increases the demand for high frame rates to meet the business starting in 2019. The audio system should be able to support both the current audio encoding and next-generation audio (NGA). With the popularization and price reduction of quantum dots and OLED high dynamic range receivers, high-end TV market in China will appear HDR ultra high-definition television this year.
9. The next generation of 3D sounds will begin testing. In a conventional channel-based mix, playback after sound mixing uses fixed speaker positions and angles, and assumes that each playback environment is the same, but there are deviations in the user's home. Next-generation sound combines traditional channel-based mixing with object-based mixing and sound field-based mixing to restore three-dimensional sound based on the user's speaker position. An object-based mix can describe single or combined sound elements in 3-dimensional space and present them to playback devices, presenting them in 1-, 2-, or 3-dimensional spatial sounds depending on the venue speaker arrangement. The acoustic field-based Ambisonics spherical surround sound technology, in addition to the horizontal plane, covers the listener's top and bottom, picks up and transmits sound field signals, and then restores the sound field according to the listener's speaker arrangement. 3D sound has already formed the corresponding international standard (MPEG-H) and industrial chip, domestic already has corresponding application.
10. Augmented Reality and Virtual Reality (AR/VR) will test the water. Virtual reality has been used for a long time in games, teaching, medical treatment, architecture, and simulated driving. In recent years, radio and television programs have also been widely used, and are currently being extended to personal applications. Since VR basically requires additional helmets, similar discomfort to 3D still exists. There have been many AR applications that link actual scenes with other information or the Internet through scanning or display glasses. Augmented reality has also been tried out in television broadcasts. But on the whole, there is still a lot of work to be done on the integration of AR/VR and TV.
The development of technology is so fast that no school graduate can use the knowledge and skills he has learned to serve the actual work. The Accenture 2016 technology concept puts forward the concept of Liquid workforce. Employees need to continuously perform various trainings. They must have liquid-like adaptability to the development of new technologies. The key to competition lies in whether they can use the most advanced technology. Technology armed people. Good water, people-oriented!
