The cloud relay platform, the unmanned hybrid interview system and the method according to the embodiments of the invention are described below with reference to the accompanying drawings.
Fig. 1 is a block diagram of a structure of a cloud relay platform according to an embodiment of the present invention.
As shown in fig. 1, the present embodiment provides a cloud relay platform 10, where the cloud relay platform 10 includes an instant interaction module 11 and a public signal making module 12.
The instant interaction module 11 is configured to receive a first code stream signal of the interview-side device, send the first code stream signal of the interview-side device to the reporter-side device, receive the first code stream signal of the reporter-side device, and send the first code stream signal of the reporter-side device to the interview-side device, so as to implement remote real-time interaction; the common signal making module 12 obtains a second code stream signal of the interview end device and a second code stream signal of the reporter end device in the remote real-time interaction process, and makes a common signal according to the second code stream signal of the interview end device and the second code stream signal of the reporter end device, wherein the code rate of the second code stream signal is greater than that of the first code stream signal.
Specifically, the cloud relay platform of the embodiment may be applied to an event interview to interview athletes after an event, and of course, may also be applied to other interview scenarios, such as an electronic product release meeting, a public character reporter release meeting, and the like, and may support one-to-one, many-to-one, and one-to-many interview modes. It should be noted that, in the embodiment of the present invention, the description is made by taking the post-event interview of the athlete as an example, wherein the interview end is the post-event athlete, and the interview end devices may include a camera, a display screen, a microphone, etc., it is understood that the interview end devices may be installed in a room dedicated to interview the post-event athlete, and may indicate on a screen in the room that the post-event athlete is in the interview area for interview. When the athlete is behind the interview area, the interview information related to the athlete, such as pictures, voice, postures and the like, can be acquired through the interview terminal equipment. The interview end equipment sends the acquired information to the instant interaction module 11 in the form of a first code stream signal, and the instant interaction module 11 sends the received first code stream signal of the interview end equipment to the reporter end equipment. The reporter end device may also include a display screen, a camera, a microphone, and the like, and the instant interaction module 11 may receive the first code stream signal corresponding to the reporter end device through the reporter end device, and then send the first code stream signal of the reporter end device to the interview end, so that remote real-time interaction between the reporter end and the interview end can be completed.
In the process of performing remote real-time interaction between the reporter side and the interview side, the public signal making module 12 can be used for obtaining the second code stream signal of the interview side equipment and the second code stream signal of the reporter side, and then making the public signal, and it can be understood that the public signal can be pushed to a new media platform, so that online audiences can watch specific interview contents between the reporter and the athletes by receiving the public signal. It should be noted that, in this embodiment, the code rate of the second code stream signal is greater than the code rate of the first code stream signal, where the code rate of the first code stream signal is lower, so that it can be ensured that remote real-time interaction between a reporter and an athlete can be smooth, and the code rate of the second code stream signal is higher, so that an interview lens with ultra-high definition television-level television effect can be generated, thereby improving the viewing experience of online viewers. It can be understood that the public signal making module 12 can also check, configure and manage the made public signal, and output corresponding to an input content and a plurality of different definitions after content transcoding, that is, including an input stream and a plurality of output streams, the cloud relay platform does not limit the number of channels, and can select one or more channels to be released as live broadcast activities or applied to a broadcast directing task, thereby realizing single-channel live broadcast, multi-channel live broadcast and cloud-end broadcast directing control. It can be understood that if the live broadcast is selected, the roll-out video bitrate required in the live broadcast can be selected, the viewing experience of different audiences under different network environments is met, and the audiences are manually switched on the player. The public signal making module 12 can also record a video, that is, in a live broadcast activity, the task progress can be checked in a recording task, deletion, preview, moving to a material library, downloading and the like can be performed, logo superposition can be completed on line, and a caption template and the like can be provided.
It should be noted that, before the athlete performs the match, the reporter or the athlete may advance to make an interview appointment through the appointment system, so that a communication channel between the reporter end and the athlete end may be established first, and then the communicable and video resources may be managed, and user management (such as registering reporter information, allocating interview authorities, etc.) may be performed to ensure the security of the channel, and then the athlete may quickly enter the interview stage after completing the match, so as to improve the efficiency.
In an embodiment of the present invention, the instant interaction module 11 is further configured to determine network transmission quality between the interview-side device and the cloud platform and network transmission quality between the cloud platform and the reporter-side device, adjust a transmission code rate between the interview-side device and the cloud platform according to the network transmission quality between the interview-side device and the cloud platform, and adjust a transmission code rate between the cloud platform and the reporter-side device according to the network transmission quality between the cloud platform and the reporter-side device.
Specifically, in this embodiment, in the process of performing remote real-time interaction between the reporter end and the interview end, if the network transmission quality between the interview end and the cloud relay platform is general or poor, the instant interaction module 11 may reduce the transmission code rate between the interview end and the cloud relay platform, so as to ensure that data in the interview end can be smoothly transmitted to the cloud relay platform, and avoid the influence on the interview efficiency due to the occurrence of a pause phenomenon in the interview process. Similarly, if the transmission quality between the reporter side and the cloud relay platform is general or poor, the instant interaction module 11 may also reduce the transmission code rate between the reporter side and the cloud relay platform to ensure that the data transmission between the reporter side and the cloud relay platform is smooth. It should be noted that if the network transmission quality between the interview end device and the cloud platform and the network transmission quality between the reporter end device and the cloud platform are improved, the transmission code rate can be improved, that is, the transmission code rate between the reporter end device and the cloud relay platform and the transmission code rate between the reporter end device and the interview end device and the cloud relay platform can be dynamically adjusted according to the respective network transmission quality, so as to realize flexible coding. For example, in the case that the network condition becomes worse, the code rate of the first code stream signal is automatically reduced to ensure that the transmission of the communication channel is stable, for example, the code rate can be reduced from 720P to 480P to 360P; and under the condition that the network condition is better, the code rate of the first code stream signal can be automatically increased, such as increasing from 360P to 480P to 720P.
In an embodiment of the present invention, the public signal making module 12 is further configured to obtain first code rate adjustment state information between the access terminal device and the cloud platform and second code rate adjustment state information between the cloud platform and the reporter terminal device, perform code rate adaptive adjustment on a second code stream signal of the access terminal device according to the first code rate adjustment state information, and perform code rate adaptive adjustment on a second code stream signal of the reporter terminal device according to the second code rate adjustment state information.
Specifically, in the process of performing remote real-time interaction between the reporter end and the interview end, the public signal making module 12 may obtain first code rate adjustment state information between the interview end device and the cloud platform, where the first code rate adjustment state information may specifically refer to the technical scheme disclosed in the above embodiment, and is not described herein again. After the public signal making module 12 obtains the first code rate adjustment state information between the access terminal device and the cloud platform, the code rate of the second code stream signal of the access terminal can be adaptively adjusted according to the first code rate adjustment state information, so that the code rate of the second code stream signal can also be adjusted according to the data transmission quality, and the smoothness of data transmission is ensured. The public signal making module 12 may further obtain second code stream state information between the reporter side device and the cloud platform, and then adaptively adjust the code rate of the second code stream signal of the reporter side device according to the second code stream state information. The second code stream state information between the reporter end device and the cloud platform can be obtained according to the data transmission quality between the reporter end device and the cloud platform, so that the code rate of the second code stream signal between the reporter end device and the cloud platform can be adjusted according to the data transmission quality, and smooth transmission is guaranteed. For example, when the network condition becomes worse, the code rate of the second code stream signal can be reduced from 4K to 2K to 1K; when the network conditions become better, the network conditions can be raised from 1K to 2K to 4K again.
In summary, the cloud relay platform according to the embodiment of the present invention can establish an instant connection line and a real-time interaction capability between the athlete and the reporter based on the low-code-stream signal (the first code-stream signal), so as to ensure real-time interaction between the reporter and the athlete and reduce an interaction delay. Meanwhile, the broadcast and television grade ultra-high definition signal video material can be distributed to a new media channel based on a high code stream signal (a second code stream signal), and the watching experience of audiences is guaranteed.
