For convenience of understanding and explanation, the broadcast internet base station and the system provided by the embodiment of the present application are described in detail below with reference to fig. 1 to 6.

Please refer to fig. 1, which is a schematic structural diagram of a broadcast internet base station according to an embodiment of the present application. The broadcast internet base station 100 includes a wireless receiver 101, a media processing server 102, a preamble distributor 103, and a base station wireless transceiver 104. Exemplarily, as described with reference to fig. 2 and fig. 3, TS code stream data of the broadcast and television single frequency network transmission tower 201 is derived from a television program and the internet, the wireless receiver 101 is configured to receive the TS code stream data broadcast by the broadcast and television single frequency network transmission tower 201, and the media processing server 102 is communicatively connected to the wireless receiver 101, and is configured to transcode the TS code stream data to obtain first IP code stream data, and store and manage the first IP code stream data; the prepositive data distributor 103 is used for connecting the second IP code stream data sent by the internet gateway 202 and all data requests sent by the base station wireless transceiver 104, and the base station wireless transceiver 104 is in communication connection with the media processing server 102 and the prepositive data distributor 103 and is used for sending the first IP code stream data or the second IP code stream data to the terminal 105.

It should be noted that the terminal 105 according to the embodiment of the present disclosure may include, but is not limited to, a mobile phone, a Tablet Computer (Tablet Computer), a palmtop Computer, a smart tv, a set-top box, a Personal Digital Assistant (PDA), a navigation device, a wearable device, and the like, and the terminal device needs to have a Super-Wifi chip module built therein.

Further, as shown in fig. 4, it is a schematic diagram of a network topology provided in the embodiment of the present application. The network topology includes a core layer, a convergence layer, and an access layer, wherein the base station 100 is disposed at the access layer. For TS code stream data of the broadcast single frequency network transmission tower 201, the TS code stream data may not pass through the core layer and the convergence layer, but be directly received by the base station 100 of the access layer; the access data of the internet gateway 202 is received by the base station 100 of the access stratum after passing through the core layer and the convergence layer. The advantages of such a configuration are that, in the embodiment of the present application, a broadcast plus bidirectional data mode is adopted, on one hand, media data is broadcast through the broadcast single frequency network transmission tower 201, which not only can perform downlink broadcast data channel shunting on traffic accessing the internet gateway 202, and save a large amount of downlink bandwidth, thereby greatly increasing the overall system capacity, significantly improving transmission efficiency and reducing transmission cost per GB, and being capable of broadcasting mass data content to the network edge by fully utilizing the advantages of broadcast, the terminal 105 can directly access the network edge server, only generates local traffic, has no other egress traffic, and significantly reduces the acquisition cost of streaming media data, the network topology data transmission cost is low and efficient, on the other hand, the terminal 105 still acquires internet service through the traditional internet service bidirectional data channel, thereby avoiding that the traditional broadcast network can only receive single downlink content, and cannot meet the current situation of bidirectional data personalized access; particularly, the method has a huge broadcast shunting effect on mass transmission contents (with the characteristic of extremely high download concentration) such as hot short videos, large games, software and the like, and greatly reduces the high cost of network capacity expansion caused by large-flow data impact in the mass data era.

It should be noted that, in the embodiment of the present application, the core layer is a high-speed switching backbone, and the main function is to provide optimal interval transmission between the convergence layer devices; the convergence layer is a demarcation point between the core layer and the access layer, and has the main functions of providing connection based on strategies, such as routing selection among VLANs, strategy routing, security strategies and the like; the access stratum is the point at which a local end user is granted access to the network, and the primary function is to provide user access to the network for multi-service applications or other network applications.

Optionally, in some embodiments of the present application, the base station 100 may include at least one of a Super-Wifi base station 1001 or a cellular network base station 1002. Illustratively, the Super-Wifi base station 1001 may include a SW6 base station, where the SW6 base station uses a TVWS frequency band, an air interface uses an IEEE 802.11ax protocol based on the TVWS frequency band, the power amplification efficiency is very high, and information of 1Gb/s magnitude can be transmitted to a kilometer distance at 10 watts. For example, the TVWS band includes any one of 470MHz to 699 MHz. Because the radio wave in the frequency range of the broadcast white band has the advantages of small free space propagation path loss, strong transmission and diffraction capabilities and the like, the equipment working in the frequency range has a wider coverage range under the same power, idle frequency band resources can be fully utilized, and meanwhile, the data content transmission in the era of mass data outbreak can be dealt with at lower cost.

The terminal 105 may include a Super-Wifi network connection mode and a cellular network connection mode, where the cellular network connection mode includes a 4G network connection mode and a 5G network connection mode, that is, the terminal 105 is a multi-mode terminal, which may not only complete the functions of the conventional mobile phone, but also view video and streaming media and other television program resources on line in real time at low cost through the Super-Wifi network.

It should be noted that, in the embodiment of the present application, a Mobile Edge Computing (MEC) is used to provide a Computing capability in a place close to the terminal 105, that is, the Computing capability is sunk to each distributed base station 100, so that functions such as Computing, storing, and processing are added on the wireless network side, thereby upgrading a conventional wireless base station to an intelligent base station. Among them, the moving edge calculation has the following features and advantages. (1) Distributed and low-latency computation: the analysis of real-time and short-period data is focused by edge calculation, so that the real-time intelligent processing and execution of local services can be better supported; (2) high efficiency: because the edge calculation is closer to the user, the data filtering and analyzing are realized at the edge node, and the efficiency is higher; (3) relieving the flow pressure: when cloud transmission is carried out, a part of simple data processing is carried out through the edge nodes, so that the response time of the equipment can be shortened, and the data flow from the equipment to the cloud is reduced; (4) the cost is low: cloud computing and edge computing are combined, and the cost is only 39% of that of the cloud computing alone. In summary, the edge computing makes the data not be transmitted to a remote cloud, but the edge computing can solve the problem, so the edge computing can better realize real-time data analysis and intelligent processing.

Optionally, an Adjacent Channel Leakage Ratio (ACLR) of the power amplifier in the base station wireless transceiver 104 according to some embodiments of the present application is greater than 55dBc, and is lower than 20dB by more than 4G base station and 5G base station, and the networking and operation and maintenance costs are low. Furthermore, the power amplifier has power amplification efficiency of more than 30% and low power consumption. Since the base station 100 operates below the frequency of the broadcast television service of 700MHz, the transmission loss is small, so the transmission distance is long, the ubiquitous performance that a 5G network does not have is provided, and the maximum throughput of a single base station reaches several Gb/s, which is equivalent to that of the 5G network, but is much larger than that of a 4G network.

Optionally, in some embodiments of the present application, the storage space of the media processing server 102 is PB level. In actual use, contents such as video programs are broadcast to an area of thousands of square kilometers in order through a connectionless broadcast television tower, received by thousands of Super-Wifi base stations 1001, and stored after TS code stream data is converted into IP code stream data. Therefore, each user can directly receive the short videos, advertisements, software downloads and other contents of the radio and television ultra-high definition television, videos and recommendation platforms which are sent by the Super-Wifi base station 1001 and stored in a memory or other storage servers through the terminal 105, only local traffic is generated, other exit traffic is not generated, the acquisition cost of streaming media data is obviously reduced, and the network topology data transmission cost is low and the efficiency is high. Of course, the user can also directly watch the television program by synchronously receiving the television video.

The embodiment of the application provides a broadcast internet base station, which is an integrated bidirectional data transmission device combining a traditional wireless transceiver unit with receiving, managing, storing and processing of receiving and receiving terrestrial digital wireless broadcast media data, and comprises a wireless receiver, a media processing server, a preposed data distributor and a base station wireless transceiver. The media processing server is used for transcoding to obtain first IP code stream data according to the TS code stream data and storing and managing the first IP code stream data; the preposed data distributor is used for connecting second IP code stream data sent by the internet gateway and all data requests sent by the base station wireless transceiver, and the base station wireless transceiver is used for sending the first IP code stream data or the second IP code stream data to the terminal. According to the method and the device, a broadcast and bidirectional data mode is adopted, on one hand, media data broadcasted to the edge of a network by a broadcast and television single-frequency network are received, so that a terminal can access and acquire the data nearby, and the acquisition cost is reduced; on the other hand, the terminal still obtains the internet service through the traditional internet two-way data channel, so that the current situation that the traditional broadcasting network can only receive single downlink content and cannot meet the two-way data personalized access is avoided; particularly, the method has a huge broadcast shunting effect on mass transmission contents (with the characteristic of extremely high download concentration) such as hot short videos, large games, software and the like, and greatly reduces the high cost of network capacity expansion caused by large-flow data impact in the mass data era.

Based on the foregoing embodiments, the present application provides a broadcast internet system. Please refer to fig. 5, which is a schematic structural diagram of a broadcast internet system according to an embodiment of the present application, wherein the system 200 includes a broadcast single frequency network transmission tower 201, an internet gateway 202, and the base station 100 in the corresponding embodiments of fig. 1 to 4. The advantage of setting up like this is that the network bandwidth of broadcast internet system 200 is extremely huge, only needs to reform transform current broadcast television network to build low cost's Wifi network, and convenient operation maintenance.

Optionally, the network corresponding to the broadcast and television single frequency network in some embodiments of the present application may include, but is not limited to, at least one of DTMB, DTMB-ase:Sub>A, CMMB, DVB-T, DVB-S, or ATSC 3.0.

It should be noted that, the DTMB employs a time domain synchronous orthogonal frequency division multiplexing (TDS-OFDM) multicarrier modulation technique filled with PN Sequence (Pseudo-Noise Sequence), which can organically combine the transmission of signals in the time domain and the frequency domain to transmit payloads in the frequency domain, and transmit control signals in the time domain by using a spread spectrum technique for synchronization and channel estimation, thereby achieving fast codeword acquisition and robust synchronization tracking performance. In the technology, (1) aiming at the traditional OFDM modulation mode of inserting the strong power synchronous pilot frequency, under the condition that the effectiveness and the reliability of a transmission system are lost, the high-protection synchronous transmission technology based on PN sequence spread spectrum and the filling technology of the OFDM protection interval in the embodiment of the application improve the spectrum utilization efficiency and the anti-noise interference performance of the transmission system. (2) Aiming at the defect that the channel estimation iteration process of the existing transmission standard of the ground digital television broadcasting is long, the TDS-OFDM channel estimation technology in the embodiment of the application can improve the mobile receiving performance of the system. (3) Aiming at the fact that the European standard DVB-T adopting the multi-carrier COFDM technology is worse than the American standard ATSC1.0 system error code threshold adopting single carrier 8VSB, the error correction coding and decoding (FEC) technology-LDPC in the embodiment of the application obtains better system error code performance than ATSC 1.0.

The technical advantages of the embodiments of the present application will be described in detail by taking DTMB as an example, and DTMB-ase:Sub>A is similar to the example. In a first aspect, a higher data transmission bandwidth is provided. Since DTMB does not need to waste as many pilot signals for synchronization and equalization as european DVB-T does, its payload transmission capacity is 10% higher than european DVB-T under the same conditions, which allows for higher data bandwidth to be provided within the same radio spectrum.

In a second aspect, greater signal coverage is achieved. Compared with the receiving threshold of European DVB-T, the DTMB has the advantage of 2dB, the receiving sensitivity is greatly improved, so that the DTMB can cover a larger area under the same transmitting condition, the coverage can be completed with less cost, and meanwhile, the electromagnetic radiation pollution can be reduced.

In a third aspect, metropolitan and provincial single frequency networks are better supported. Due to the frame structure of DTMB strictly synchronous with absolute time, compared with the same equipment of European DVB-T, the digital television receiver can more easily realize a single frequency network for simultaneously transmitting the same signal at the same frequency, saves non-renewable wireless frequency resources, and simultaneously can ensure a single frequency network supporting mobile reception in a larger-range metropolitan area and a province area.

And in the fourth aspect, the technology is prepared for the sustainable development of the terrestrial digital television. Due to the unique signal frame structure of the DTMB, multi-service broadcasting can be fused. The DTMB provides a new development space for high-speed information user access and mobile communication fields while solving the problem of digital high-definition television transmission. These new services mainly include the further expansion of internet applications, the addition of multicast, on-demand and call-guiding services, the expansion of comprehensive and interactive application services such as video, data, voice and the like, the development of more portable mobile receiving services including the reception of digital television by mobile phones and the like, and the further development of receiver positioning services.

The following describes the broadcast internet system 200 according to an embodiment of the present application in detail with reference to an application scenario of fig. 6. Because the broadcast television network is a unidirectional broadcast system and lacks a bidirectional interactive channel, the Super-Wifi base station 1001 is used for realizing ground bidirectional wireless data coverage in the embodiment of the application, and low-cost data transmission service can be provided in mobile and fixed service scenes.

For example, in a mobile scene, the Super-Wifi base station 1001 receives and stores data of the broadcast single frequency network transmission tower 201, and the terminal 105 in the sector covered by the Super-Wifi base station 1001 is a multi-mode terminal, supports Super-Wifi access, and supports access of 4G and 5G networks. The Super-Wifi base station 1001 is connected to a cloud service platform through the internet gateway 202, and the cloud service platform comprises an internet outlet, a Super-Wifi gateway, a data roaming management system, a video program source, large-scale software, a recommended optimal algorithm management system and the like, so that the terminal 105 can directly access the video and streaming media content broadcasted by the radio and television single frequency network transmitting tower 201 and stored in the Super-Wifi base station 1001. Because the Super-Wifi base station 1001 is provided with a PB-level memory, a traditional IP bearer Network does not need to access the Content of a related Content Delivery Network (CDN) around a large circle locally and remotely, only local Network traffic is generated, and the cost is much lower than that of data traffic. Data such as videos, short videos and streaming media can be obtained at extremely low cost under the framework, meanwhile, a large amount of downlink bandwidth is saved in a Super-Wifi network, and the Super-Wifi network is different from a traditional 4G network or a 5G network, and novel applications such as uplink live broadcast and the like can obtain more channel resource supports. Due to the fact that the data transmission efficiency of the broadcast mode is high, data such as short videos, advertisements, software downloading and updating and the like on the video optimization algorithm platform can be obtained more simply, and the defects of the network are overcome.

For example, as shown in table 1, if the ratio of the network upstream and downstream traffic (or bandwidth) is 2:8, after the video program with the highest downlink concentration and the large common software are played by the broadcasting tower through the big data recommendation algorithm, the downlink bandwidth is saved by 70%, and the total network bandwidth can be saved by one time (56%), so that the uplink and downlink traffic of the network can be greatly saved. It should be noted that, in the embodiment of the present application, the ratio of the network uplink traffic to the network downlink traffic is 2:8, that is, the ratio may be other values, which is not limited.

Table 1 downstream traffic splitting

TT	UDR	DBR	BTT	TTR
					100％	2:8	70％	56％	44％
100％	2:8	80％	64％	36％

Wherein TT (Total Traffic) represents Total network Traffic, UDR (Upper Down Ratio) represents a Ratio of uplink to downlink Traffic, DBR (Down Traffic Bypassed Ratio) represents a downlink Traffic splitting Ratio, BTT (Bypassed Total Traffic) represents Total split Traffic, and TTR (Total Traffic remaining) represents remaining Total Traffic.

In a fixed scene, as the ratio of the own optical fiber lines of the radio and television wired networks in various regions is low, most of the radio and television wired networks are leased operator lines, and the stock of optical fibers is extremely limited. Therefore, in The embodiment of The application, the edge cloud storage center 203 is built near The cell, the FTTB (Fiber to The Building) from The optical Fiber Ethernet to The corridor or The passive optical network is connected to The corridor, the entrance of The home is completed through The Super-Wifi, so that The 4-8K local television programs are transmitted to The home, and The set top box is additionally provided with The chip module of The Super-Wifi or The smart television is directly implanted into The chip module, so that The local IPTV program, the live broadcast and The OTT program can be watched.

In summary, the broadcast internet system 200 provided in the embodiment of the present application completes downlink distribution of mass data in a broadcast manner, which is equivalent to increase the capacity of the entire network bandwidth, and more bandwidth can be allocated to live video uplink services such as jittering and the like. When the user and data flow are increased rapidly, the transmission service requirement can be met without linear expansion of network equipment, the mass downlink bandwidth is saved, the whole network capacity and the data transmission efficiency are improved, and the transmission cost per GB is reduced to be below $ 0.1. Meanwhile, a connectionless-oriented mode is introduced into network design to provide extremely low mass downlink bandwidth, which is one of core concepts in future 6G network design.
