Fig. 1 is a schematic diagram of a prior art stadium information publishing device, which includes:
the information sending terminal 101 is typically a computer or a live video server. The computer is provided with information release software and has the functions of managing an information receiving end, sending public information to the receiving end and the like. Public information content includes announcements, welcome words, advertisements, trailers, live game scenes, and the like. The video live broadcast server can compress and push the signals of the camera or other video input devices to an IP network, and then the signals are decoded and output to the display terminal by the information receiving terminal.
The information transmission device 102 is based on an IP network, and the hardware devices include switches, optical fibers, network cables, and the like, and may use a private network inside a venue or an independent private network for information distribution.
The information receiving device 103 is used for converting the multimedia information on the network into a video signal interface, such as VGA, DVI, HDMI, etc.
The information display terminal 104, which is generally a liquid crystal display or a liquid crystal television, is used in cooperation with the information receiving device. The information display terminals are distributed in all corners of the stadium, such as entrances and exits, corridors, VIP boxes and the like.
Generally, the building area of the venue is large, the terminal devices are distributed dispersedly, and centralized information publishing and unified management are required to be carried out on each terminal device. The display screen in the venue can be utilized to play the role of a notice board, and also can display information such as videos, pictures, time, weather and the like.
The existing stadium information publishing system uses video coding compression technology when transmitting real-time signals. The video source signal is generally from a relay car or a camera, the analog video signal of the camera enters an information sending end, is compressed into a digital signal by using H.264/H.265 or other video coding technologies, and is transmitted to an information receiving device through an IP network, and the information receiving device decodes the digital signal into a video interface signal and outputs the video interface signal to a television or an LCD screen for display. But the displayed content is uniformly distributed and controlled by the administrator.
However, in the prior art, because the streaming media video source adopts a compression technology with a high compression ratio, the display definition of the terminal cannot achieve the ultra-high definition display effect. Due to the problems of video source compression and soft decoding delay of the terminal, the real-time video of the game is generally delayed for 3-4 seconds when being displayed at the terminal, and the user experience is poor. In addition, because the displayed content is issued and controlled by the administrator uniformly, the user cannot switch the video source to be watched by himself, and the flexibility is insufficient. In addition, if the terminal uses a television as a display terminal, the management terminal cannot control the power switches of the television one to one, and the management efficiency is low.
In view of the above technical problems, embodiments of the present application provide a method and an apparatus for publishing stadium information, so as to implement non-compression and ultra-low delay transmission of a 4K ultra-high-priority video, thereby improving user experience. Support compression transmission when not compression transmission, be convenient for set up different equipment according to the scene of difference to every display terminal can show different content through the mode of split screen, and every display terminal can long-rangely open or close the power, thereby improves flexibility and managerial efficiency.
It should be noted that the 4K ultra-high-definition signal source described in this embodiment is specifically defined as a signal source with a resolution of 3840 × 2160 (wide × high) and a refresh rate of 60Hz at the highest. The higher the refresh rate, the greater the network bandwidth requirement, e.g., 60Hz bandwidth is 2 times the 30Hz bandwidth requirement. The refresh frequency is 4K super high definition signal source of 60Hz, can be called as 4K @60Hz signal source for short.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
It should be noted that the display sequence in the embodiments of the present application only represents the sequence of the embodiments, and does not represent the advantages and disadvantages of the technical solutions provided by the embodiments.

The first format code is an uncompressed code to meet the requirements of ultra high definition and ultra low delay display. As a preferred example, the first encoding format may be SDVOE encoding, which is described herein as SDVOE (Software Defined Video-over-Ethernet) Ethernet-based Software Defined Video.
The second format code is a high-compression code, so that the high-compression code is compatible with high-compression coding equipment in the prior art, the requirements of occasions without ultra-high definition display and low delay requirement are met, and the cost is reduced. As a preferred example, the second encoding format may be h.264/h.265 encoding. Among them, h.264 may also be referred to as AVC (Advanced Video Coding), and h.265 may also be referred to as HAVC (High Efficiency Video Coding).
In this step, the first format encoding and the second format encoding are performed simultaneously. Carrying out first format coding on a video signal source to obtain first format data; and carrying out second format coding on the video signal source to obtain second format data.
S203, outputting the first format data and the second format data to a first network switch, and outputting the second format data to a second network switch;
in the embodiment of the present invention, the first format data and the second format data are transmitted through different network switches, corresponding to the first format data and the second format data in step S202. The transmission rate of the first network switch is greater than the transmission rate of the second network switch.
The first network switch is a gigabit network switch and is used for transmitting data in a first format; the second network switch is a gigabit network switch and is used for transmitting the second format data.
In the embodiment of the invention, the first format data is uncompressed, the second format data is highly compressed, the first format data volume is larger than the second format data volume by the same video signal source. In order to output the encoded data to the corresponding network switch, the rates of the transmission interfaces are respectively required to meet the requirements of the first format data and the second format data. As a preferred example, the first format data is output to a gigabit network switch through a gigabit optical fiber; the second format data is output to a gigabit network switch through a gigabit fiber, and the second format data can be output to the gigabit network switch through a gigabit fiber.

In steps S204 and S205, the first signal receiving box is a receiving box matched with the first format data, that is, a receiving box capable of receiving and decoding the first data is provided. Accordingly, the second signal receiving box is a receiving box matched with the second format data, that is, a receiving box capable of receiving and decoding the second data is provided.
As a preferred example, when the first format encoding is SDVOE encoding, the first signal-receiving box is an SDVOE signal-receiving box; when the second format code is H.264/H.265 code, the second signal receiving box is H.264/H.265 signal receiving box.
The interface between the first signal receiving box and the second signal receiving box and the display terminal needs to meet the transmission requirements of the first display data and the second display data. Accordingly, the first display data is an ultra high definition 4K signal, and the transmission rate requirement is higher than the transmission rate requirement of the second display data decompressed after the compression.
As a preferred example, the first display data is output to a display terminal through the HDMI interface; and outputting the second display data to a display terminal through the HDMI interface.
It should be noted that the first signal receiving box and the second signal receiving box may be integrated in the same receiving box, that is, the same receiving box, and can simultaneously receive and decode the first format data and the second format data. The first signal receiving box and the second signal receiving box may be separate and independent receiving boxes.

the whole interface not only gives consideration to the live broadcast requirement when a plurality of events are carried out simultaneously, but also gives consideration to the publishing and displaying of public information.
Split screen mode 2:
as shown in fig. 6, in a game such as basketball and tennis, only one game is played in the same time field, so that the signal source 1 is accessed to a live game picture, and the signal source 2 is accessed to a game result and data analysis statistical picture of the timing and scoring system;
the bottom column content is in the same split screen mode 1.
Split screen mode 3:
as shown in fig. 7, in the games such as table tennis and curling, a plurality of groups of games are simultaneously played in the field, so that a signal source 1 is accessed to a first group of live broadcast pictures, a signal source 2 is accessed to a second group of live broadcast pictures, and similarly, a signal source N is accessed to an nth group of live broadcast pictures (generally, 4 signal sources are available);
the bottom column content is in the same split screen mode 1.

The first format coding and the second format coding (for example, the SDVOE coding and the H.264/H.265 coding are simultaneously used) are used for considering both the functional requirement and the management cost, and the SDVOE version signal receiving box is configured at important positions, such as a VIP box, an entrance, an exit and the like, so that ultra-high-definition non-delay pictures are provided for users. In general locations, such as elevator rooms, corridors and mobile equipment, the H.264/H.265 version signal receiving box or the integrated machine with lower cost is used, so that the expense is saved.
By the stadium information publishing method provided by the embodiment, the split screen display function can be realized, and users can check different video source signals at the same time. For example, a field and a track may be played simultaneously in a stadium, and the user may watch different events simultaneously. The user can also select the signal source which the user wants to watch in a full screen mode by using the remote controller.
