Benefits of technology

The technical effect of this patented technology allows for easier upgradation from 480p videos into 30 frames at 1920x speed without requiring expensive equipment like high definition cameras that are used during production. Additionally, it ensures accurate remote broadcasts even when there may be temporary inclement weather conditions such as rain or snow can affect their quality.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving upon current methods of playing back videos recorded at different locations during four KV cameras' live broadcastings due to their expensive infrastructure requirements.

Embodiment 1

[0029] as attached figure 1 , attached figure 2 And attached image 3 The shown visual VR guide system for venue control includes a demultiplexing module, an audio and video cache module, a decoding video module, a monitoring module, a switching logic module and a streaming multiplexing module, including the following steps:

[0030] S1: Input the rtmp stream into the demultiplexing module, and then the demultiplexing module pulls the 8K rtmp live stream and demultiplexes it;

[0031] S2: Import the demultiplexed data of S1 into the audio and video cache module, then use the audio cache module to read from the cache, and then decode the corresponding video;

[0032] S3: Input the decoded video in S2 to the monitoring module, zoom and display it in a specified window, and issue a switching command to notify the switching module to switch;

[0033] S4: Enter the switching logic module, receive the switching command through S3, and use the audio time axis as a reference to sw...

Embodiment 2

[0045] Concretely with the bureau difference of embodiment 1 and wherein the initial data flow in the audio module is four groups; Embodiment 3

[0046] Concrete and the bureau difference of embodiment 1 and the initial data flow in wherein said audio module are two groups; Experimental example

[0047] Three sets of equipment were used, and the technical means in Examples 1, 2, and 3 were respectively installed, and then the data transmission volume per second during the four sets of operations was recorded.

[0048] Example 1 Example 2 Example 3 Data transfer volume / second 92.2M 176.4M 160.3M

[0049] To sum up: In the same cost budgeting process, the efficiency of the existing three sets of data flow supply is the best.

Abstract

The invention discloses a visual VR director system for meeting place control, and relates to the field of VR directors. The system comprises a demultiplexing module, an audio and video caching module, a video decoding module, a monitoring module, a switching logic module and a plug flow multiplexing module, and comprises the following operation steps: S1 inputting rtmp pull flow into the demultiplexing module, and then pulling 8Krtmp live broadcast flow by the demultiplexing module and demultiplexing the 8Krtmp live broadcast flow; and S2 importing the data demultiplexed in the step S1 into the audio and video caching module, reading a corresponding video from a cache by utilizing the audio and video caching module, and then decoding. According to the invention, the demultiplexing moduleis added to zoom the original 8k video resolution to 2K or lower video resolution for preview switching; the cloud deployment reduces the front-end hardware cost, reduces the early-stage manufacturingdifficulty, enables each video transmission to be stably monitored through the arrangement of the monitoring module, greatly guarantees the remote broadcast guide precision, and solves a problem thatthe playing is not convenient caused by a live broadcast accident.
