Propagation system applied to small fields

This creation is about a communication system, especially a communication system applied to small fields.

In recent years, with the increasing popularity of wireless communication devices such as mobile phones and the rapid development of high-speed wireless communication networks, people have gradually become accustomed to extracting various multimedia messages such as sounds, videos, and movies from the Internet anytime and anywhere.

However, the use of wireless devices such as mobile phones is a point-to-point transmission. Therefore, if more than one person intercepts the same data at the same time, the same data will be repeatedly transmitted to different users, resulting in unnecessary spectrum usage. This leads to a decline in overall network speed. Especially in the small field, when multiple people use it at the same time, such as concerts, it often causes network traffic jams, making it impossible for people who need to contact to obtain spectrum resources. In the face of the future construction of smart cities, it is foreseeable that when there are more devices, there is a need for wireless devices such as mobile phones, which may not meet the demand for large amounts of data transmission and update. Therefore, a new wireless communication method is urgently needed. Solve the above problem. At the same time, due to the rise of the Internet, the traditional television or communication has spread the trend, and some of the spectrum is left white.

In view of the above problems faced by the conventional communication method, the present invention provides a propagation system applied to a small field, including: a transmitting and transmitting device, which utilizes an unused frequency band in the small field to transmit information from a signal source. And transmitting in the small field; and transmitting and receiving the device, receiving the information transmitted through the frequency band.

Preferably, as in the foregoing propagation system, the signal source is an image capturing device for capturing an image as the information. The source of the signal is an information integration device that integrates data from multiple parties into the information. At least one of the multi-party data captures the picture in the small field by the video capture device, and at least the other party is the information input by the data editor. The small field refers to the concert venue, the exhibition venue or the sports venue. The frequency band refers to the broadcasting band or the digital TV band.

As described above, since the information is transmitted using a one-to-many propagation method, information can be transmitted to multiple users at the same time, which can effectively solve the peer-to-peer network communication, and the same information is repeatedly transmitted to the multi-user. The bandwidth caused by people is wasted, and the situation of network traffic jams is avoided. In addition, by intra-area broadcast or idle spectrum in digital TV, it is possible to effectively transmit information in a small field without disturbing the existing spectrum, thereby avoiding spectrum interference and achieving efficient information dissemination.

The video recorder 132 integrates the video, sound, special effects, and the like from the other information device 134 on the screen returned by the plurality of cameras 131, and transmits the code to the encoder 133 for encoding. After the encoding, the image to be returned by the plurality of cameras 131 becomes a plurality of information to be transmitted, and It is transmitted to the propagation transmitting device 12.

When the plurality of pieces of information to be transmitted are transmitted to the propagation transmitting apparatus 12, the plurality of pieces of information to be transmitted are first transmitted through the multiplexer 121, and then transmitted to the switch 122. The switch 122 stores the information to be transmitted to the code stream storage device (not shown), and transmits the information to be transmitted to the transmitter 123 to convert the information to be transmitted into an electromagnetic signal for transmitting the transmission. Finally, the electromagnetic signal is transmitted to the distributor 124, and the electromagnetic signal for transmitting and transmitting is transmitted to the space of the concert hall 18 through the antenna 125 disposed at different positions.

The viewer in the concert can transmit the receiving antenna 141 on the receiving device 14, receive the electromagnetic signal, and then decode and restore the electromagnetic signal through the receiver 142, so that the camera can be viewed and returned by the plurality of cameras 131. 132 integrated screen. The audience can enjoy different angles of the concert at the same time in the concert. In addition, if there is a special situation that needs to temporarily leave the venue, you can enjoy the uninterrupted concert content on the way to achieve a richer concert experience.
