Introduction to Audio and Video Transmission Projects
(1) Introduction to the Broadcasting Signal Assurance System for the 11th National Games
As the most important comprehensive sports event in the country, the 11th National Games has garnered widespread attention from the public. This places high demands on the live broadcast signal assurance system for the event. To fully support the National Games and accomplish this honorable yet challenging task, Onebandxin has designed a comprehensive backup plan for the assurance system and dispatched an experienced technical team to provide maximum support for the broadcast assurance.
Oneband has developed a detailed support plan for the 11th National Games. The National Games will be jointly hosted by cities including Yantai, Dezhou, Jining, Liaocheng, Linyi, Zaozhuang, Heze, Zibo, Weifang, Tai'an, Dongying, Binzhou, Weihai, Rizhao, Laiwu, Qingdao, and Jinan. Each city will have corresponding competition venues and events, and the signals from each competition venue must be uniformly transmitted to the dispatch center for signal switching and output.
From the competition venues in various cities, two signal paths, one primary and one backup, are output and enter the primary and backup optical terminal equipment via optical cables. These signals are transmitted to the local broadcasting station's equipment room, where the primary and backup encoders encode the signals separately and output DS3 signals to the Shandong Broadcasting SDH transmission network for transmission. The Shandong Broadcasting SDH transmission network consolidates all 17 real-time primary and backup signals from the competition venues and transmits them to the dispatch center, where they are allocated to their respective decoders. This decodes 17 primary signals and 17 backup signals, with each signal subsequently entering the corresponding SDI distributor, which distributes the SDI signals for monitoring, testing, and transmission to the dispatch center.
The design of the entire system comprehensively considers the primary and backup switching, with each signal having a corresponding backup signal. Each device and every link achieves complete 1:1 redundancy, ensuring that there are no single points of failure in the entire system. This maximally guarantees the signal transmission for the National Games and provides a solid foundation for the security assurance of the event. This is also a representative work of Onebandinp, demonstrating its strong technical capabilities in ensuring the safety of major events.
(II) Introduction to the Meteorological Channel Transmission Coverage and Insertion System of the China Meteorological Administration
The Meteorological Channel is a professional satellite channel broadcasted nationwide by the China Meteorological Administration, operating 24/7 with continuous rolling broadcasts. In addition to airing professional information and educational content, it also regularly broadcasts real-time meteorological information. Due to China's vast territory and diverse climates, local meteorological bureaus are allowed to broadcast half an hour of local meteorological information programs on the Meteorological Channel to timely disseminate real-time weather information to the public. The flowchart of the entire system is as follows:
The system's process is described as follows: The program content produced and broadcasted by relevant studios is encoded and compressed, then transmitted via fiber optics to the Dingshi Media satellite platform, where it is scrambled and sent to Zhongxing 6B, achieving nationwide coverage.
At the meteorological information centers of the provincial and municipal meteorological bureaus, there are two methods for inserting local meteorological information:
One method is for the local cable network front end to receive the Meteorological Channel from the satellite, unscramble it, and output the ASI transmission stream. This stream is then sent to the local meteorological information center using an ASI optical device, where it is decoded by a professional decoder to output an SDI signal to the SDI switcher. The center's broadcast control system is responsible for broadcasting the local meteorological information program content to be inserted in SDI format, sending it to the SDI switcher. The SDI output from the switcher is sent to the UE-9000 / Ellipse1000 encoder, and the encoded and compressed ASI signal is then transmitted via the ASI optical device to the local cable network front end equipment room.
The other method is for the meteorological information center to directly receive the Meteorological Channel from the satellite, where it is unscrambled and decoded by a professional decoder equipped with satellite reception, outputting an SDI signal to the SDI switcher. The broadcast control system and subsequent processes are the same as above.
Typically, the SDI switcher outputs the Meteorological Channel content from the cable network front end or satellite to the UE-9000 / Ellipse1000 encoder. The encoded and compressed ASI transmission stream is sent via the ASI optical device to the cable network front end equipment room. Based on the insertion schedule negotiated between the provincial and municipal meteorological bureaus and the National Meteorological Administration, the broadcast control system controls the SDI switcher to switch the local meteorological information program content to the subsequent encoder for encoding and compression, thus sending it via the ASI optical device to the cable network front end equipment room; this achieves the insertion of local meteorological information.
(III) Introduction to the Medium Wave Broadcasting Audio Codec Transmission System of the Henan Provincial Radio and Television Bureau
The Radio Management Center of the Henan Provincial Radio and Television Bureau aims to improve the safety and transmission quality of the signal sources required by various transmission stations, necessitating the construction of a program transmission system. This project expands the program transmission network of the provincial people's broadcasting station, where 7 sets of broadcast program signals are transmitted through Skopas codec equipment via an SDH optical fiber network to 18 municipal transmission stations, forming a broadcast program optical fiber network transmission system organized with the decoding equipment equipped at each transmission station. The flowchart of the entire system is as follows:
The management center receives signals for 7 broadcasting programs from the provincial people's broadcasting station, which are transmitted to the management center via E1 links. At the management center, the signals are distributed through an E1 distributor and decoded into 7 channels of analog stereo audio using two decoders that support 4-channel stereo audio decoding. The left and right channels of the stereo audio are then mixed together to create one mono channel (a total of 7 mono channels), which are sent to an encoder for compression and output through its IP output port, resulting in 7 mono IP transmission streams. Finally, these streams are transmitted via an SDH optical fiber network to 18 medium wave stations, each equipped with decoders and audio matrix equipment that have IP input interfaces. The existing satellite reception signals serve as backup signal sources, forming a fiber optic network transmission system for broadcasting programs, providing a secure and high-quality signal source for medium wave transmitters.
Due to the varying program requirements and quantities needed by each medium wave station, the decoders allocated to the 18 medium wave stations differ as well. Five of the medium wave stations are equipped with decoders that have 8 mono audio decoders (with corresponding audio matrices of 16x8 capacity), while the remaining medium wave stations are equipped with 4 mono audio decoders (with corresponding audio matrices of 8x4 capacity).
Introduction to the Bidirectional Network Renovation Project

Consequently, the demand for spiritual and cultural life has also increased, placing higher demands on broadcasting and television. Under these new requirements, the performance of analog microwave equipment, which can only transmit one set of television programs and three mono broadcasting programs per channel, is far from meeting the needs of modern societal development. With advancements in science and technology, the production of broadcasting and television programs is gradually transitioning to digital formats, with digital video broadcasting (DVB), digital audio broadcasting (DAB), and high-definition television (HDTV) programs already in operation. Digital programs require digital transmission methods.
The broadcasting and television microwave transmission network bears significant political responsibilities. It is one of the security and early warning systems for national and local safety, a vital channel for fulfilling political tasks, a platform that ensures high reliability in broadcasting and television service transmission, and an important transmission method for resisting natural disasters and countering human-made destruction.
The SDH digital microwave network can transmit dozens of television programs and audio broadcasting programs, not only delivering more high-quality broadcast television signals to various stations and remote rural areas but also promoting the development of broadcasting and television technology in different districts and cities, thereby achieving broader coverage. Additionally, by utilizing the digital environment of digital microwave technology, a two-way interactive information network can be established, enabling comprehensive utilization and development of network functions, which is beneficial for the advancement of government information initiatives.
The encoder and SDH microwave integrated system of Dongguan Broadcasting and Television Station consists of the following three components: digital television signal processing system, multi-service transmission and access, and SDH microwave transmission platform.
In the digital television signal processing system, our company has adopted the ION standard definition multiplexer, Ellipse1000 high-definition encoder, and ProStream1000 stream processing platform from Harris Corporation, in conjunction with the NMX intelligent network management system to achieve encoding and multiplexing of all high-definition and standard-definition signals, and to enable emergency switching of primary and backup devices and signals in the system through network management. This ensures stability and safety in the digital television signal processing phase.
The multiplexed video signals that have been encoded require combining processing, converting unstructured digital signals into structured digital signals through multiplexing equipment. In the system, we use the ADP2000 DS3 adapter to convert the signals into DS3 structure for transmission via the SDH transparent channel.
To achieve digital television broadcasting transmission and comprehensive utilization of bandwidth for uplink and downlink television program services, we have configured the Fujitsu SDH multi-service transmission platform in the system. This equipment comes in various capacity types, including STM-1/155Mbps, STM-4/622Mbps, STM-16/2.5Gbps, and STM-64/10Gbps, enabling connections to SDH microwave (1+1)/STM-1 to 2x(7+1/8+0)/STM-1 systems; service interfaces include E4/140Mbps, E3/34Mbps, DS3/45Mbps, E1/2Mbps, 10/100 Ethernet, and Gigabit Ethernet interfaces, meeting various broadcasting service requirements. Typically, the DS3/45Mbps frame structure is selected to transmit multiple compressed video broadcast signals, fully utilizing the channel bandwidth. The E1/2Mbps frame structure is chosen for transmitting compressed video conferencing signals or broadcasting value-added service signals, allowing flexible application of different data bandwidths. The selection of Ethernet interfaces and bandwidth mapping can be conveniently set according to specific needs. This equipment features a built-in large-capacity cross-connect matrix, enabling point-to-point and point-to-multipoint connections for VC3, VC4, and VC12 granularities, with powerful cross-connection capabilities and flexible service bandwidth management functions. Therefore, this equipment not only meets the diverse functional requirements of the aforementioned services but also provides Ethernet interfaces with layer 2 switching capabilities and network transmission functions, facilitating the transmission of multiple service requirements within the same transmission network.
The SDH microwave transmission method can achieve the reception and transmission of Dongguan Broadcasting and Television Station's digital broadcast television signals at its three microwave sites, characterized by high capacity, long distance, and wide range. SDH microwave is the primary choice for long-distance and wide-range transmission solutions for digital broadcast television signals. In this system, we have selected NEC's SDH microwave equipment, allowing for the selection of transmission capacities based on the number of television programs to be transmitted, such as (1+1)/STM-1/155Mbps, (3+1)/STM-1/155Mbps, with a maximum capacity of 2x(7+1/8+0)/STM-1/155Mbps. For long-distance solutions, frequency ranges of 4/5/6/7/8GHz can be chosen, while short-distance solutions can select frequency ranges of 10/11/13/15/18/23GHz. Depending on the geographical distribution of the television transmission stations, single-hop or relay methods can be selected to achieve long-distance transmission network connections, addressing areas that wired methods cannot reach due to complex terrain. The SDH microwave operates safely and reliably, reflecting a reasonable routing topology network structure, meticulous frequency planning, appropriate antenna height and feeder configuration, and effective spatial diversity measures, which avoid internal and external system interference, showcasing the high quality, high performance, and high reliability of NEC SDH microwave equipment.
