Detailed Description
in order to make the technical solutions and advantages of the present invention more apparent, the following further detailed description of exemplary embodiments of the present invention is provided with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and are not exhaustive of all embodiments. And the embodiments and features of the embodiments in the present description may be combined with each other without conflict.
the inventor finds that although no APP interactive connection system special for the radio-frequency level is provided in the prior art, a system for interactive connection by using civil software (hereinafter referred to as a civil interactive connection system) already exists, in the civil interactive connection system, the civil software also plays a transitional role as a temporary substitution scheme, and the civil interactive connection system consists of four parts, namely a connection system, a video conversion system, an audio conversion system and a connection conversation system.
a) the connection system is characterized in that civil connection software such as WeChat and QQ is used for network connection, a back-field receiving tool is a computer capable of outputting VGA signals, and a front-field reporter uses a mobile phone as a connection tool.
b) In the video conversion system, since the video signal returned from the civil software cannot enter the broadcast and television production and broadcasting system, the desktop of the operating system needs to be output to the professional information source conversion equipment through the VGA interface of the back field computer. And the professional information source conversion equipment converts the VGA signal into an SDI signal and outputs the SDI signal to a large screen of a studio for use.
c) In the online conversation system, as the civil software can only support one path of audio return at the same time, the front reporter can only hear the voice of the host through the mobile phone and cannot hear the sound of the director. To solve this problem, the system can only prepare one more mobile phone for the former reporter to talk directly to the director in the studio.
d) the audio conversion system, because the audio and video signal of the civil system are separated, does not contain the audio in the screen projection signal, so need an extra audio conversion system to imbed the audio signal into SDI signal, make the audio and video synchronous, just can receive for broadcasting and TV system.
By understanding the architecture and working principle of the civil interactive connection system, it can be concluded that the civil interactive connection system mainly has the following disadvantages:
the safety of the civil software is not good enough, and the civil software with uncontrollable technology is always applied to the interactive connection line, so that the safety hazard exists. The user is not examined and authenticated, and the risk of the software for the embedded advertisement is also not controllable.
The output signal has potential safety hazard, as the civil software is only a tool for civil communication, the front field signal cannot be output through the SDI signal, and the only method is to output the desktop signal of the operating system after signal conversion. External conversion equipment is needed, so that the reliability of the whole link is reduced, and the desktop of the operating system is used as a signal output source and is a broadcasting potential safety hazard.
The two-way three-wire real-time conversation is not realized, and the director can only carry out the off-line conversation with the front reporter through another telephone in the conversation process of the host and the front reporter, so that the operation complexity of the front reporter is increased, and the control force of the director on programs is obviously reduced.
The embodiment of the invention provides an interactive connection processing method, a server, a system and a mobile terminal, which are described below.
Fig. 1 shows a server-side interactive connection processing method in an embodiment of the present invention, which includes:
Step 101, receiving a connection application sent by a mobile terminal and reminding the connection application;
Step 102, entering a pre-monitoring stage according to the first broadcasting instruction, wherein the pre-monitoring stage comprises: selecting a monitoring channel for the connection application according to a first guide instruction so as to pass the connection application, and receiving a video and audio signal sent by the mobile terminal in the monitoring channel; receiving an audio signal of the broadcasting-directing audio equipment and feeding back the audio signal to the mobile terminal;
Step 103, entering a connection interaction stage according to a second program guide instruction, wherein the connection interaction stage comprises: the video and audio signals are subjected to modulation and resolution processing according to the second broadcasting instruction and sent to the studio switching station; and receiving and synthesizing the audio signals of the host audio equipment and the director audio equipment, and feeding back the audio signals to the mobile terminal.

Step 307, the studio director sends out a second director instruction, and switches the signal corresponding to the reporter to the PGM (PROGAM, main output) channel;
Entering the connection interaction phase according to the second guide indication, and steps 307, 308, 309, 311 are the connection interaction phase processing of the interactive connection server, and starting the connection interaction.
Step 308, the interactive connection server performs modulation and resolution processing on the video and audio signals according to the second director instruction, converts the processed video and audio signals into SDI signals which are general for broadcasting and television systems, and sends the SDI signals to the studio switching station;
In this step, the video signal of the passerby is modulated and transferred to meet the requirement of PAL modulation broadcasting of 25 frames per second, and the pictures with different picture resolution transmitted by the mobile terminal are converted into standard 720P signals. Since the resolution of the camera of the mobile terminal is usually not sufficient to be 720P, the resolution processing here is usually up-conversion.

After which the moderator can interact with the reporter.
and 310, receiving and synthesizing the audio signals of the host audio equipment and the director audio equipment, and feeding back the audio signals to the mobile terminal.
in the step, the audio bidirectional three-wire connection between the host audio equipment and the broadcasting audio equipment and the audio bidirectional three-wire connection between the host audio equipment and the mobile terminal are established for interactive connection.
After the front reporter and the host finish the interactive connection, the front reporter or the director can close the interactive connection, thereby ending the interactive connection.

By adopting the scheme of the embodiment of the invention, the defects of the traditional interactive connection system and the civil interactive connection system are overcome, and the method comprises the following steps:
1. The defects of the traditional interactive connection system are overcome:
Defect one: video recording system of traditional interactive connection system is heavy
Because the traditional interactive connecting line system uses a professional camera to collect video and audio, the equipment is heavy and inconvenient to carry. The embodiment of the invention only uses the mobile phone as the shooting and recording equipment, thereby being convenient and fast. And with the continuous improvement of the hardware performance and the network bandwidth of the mobile phone, the video shot by the mobile phone can completely meet the requirements of the program set on the interactive connection resolution.
And defect two: connection time inflexibility of traditional interactive connection system
The embodiment of the invention can adopt a 4G network or Wi-Fi as a transmission channel, can carry out interactive connection at any time and any place, does not need to reserve satellite resources and is not limited by a connection point line.
And a third defect: the operation of the traditional interactive connecting line system is complicated
The traditional interactive connection system not only needs a front team to perform operations such as camera shooting and transmission line maintenance, but also needs an additional connection communication system to return a back audio signal. The embodiment of the invention abandons a heavy camera and abandons additional conversation equipment, so that a former reporter can finish interactive connection work which can be finished by combining the camera and the conversation mobile phone only by using one mobile phone.
and a fourth defect: the manpower cost of the traditional interactive connecting line system is large
The traditional interactive connection system at least needs three forecourt teams to support one-time connection, and the embodiment of the invention can complete the whole process of the whole interactive connection by only one front reporter.
2. the defects of a civil interactive connection system are overcome:
Defect one: the safety of the civil interactive connecting line system is not good enough
The embodiment of the invention can be provided with an account management system, in the embodiment of user verification, only a professional reporter authorized by the management system has the authority to use the reporter special APP, and only an authorized user can be connected, and the program is controllable, thereby reducing unknown risks and greatly improving the safety of the system.
and defect two: potential safety hazard of output signals of civil interactive connecting line system
the embodiment of the invention uses the pure video signal as an output source, but not a mode of operating system desktop projection and SDI conversion, and the mode of operating system desktop projection and SDI conversion is easy to cause broadcasting accidents due to misoperation in the interactive connection process.
And a third defect: civil interactive connection system does not solve the problem of two-way three-wire call
