Abstract

The invention provides a dual-coding cloud director method and system. The method comprises the following steps: collecting video signals shot by a plurality of cameras in each shooting scene; respectively coding the video signals shot by each camera in each shooting scene into multiple paths of coding signals with different time delays and resolutions; screening out a first type of coded signalsof each shooting scene of which the time delay is less than a time delay threshold; screening out a second type of coded signals of each shooting scene of which the resolution is higher than a resolution threshold; performing clock time service on the first type of coded signals and the second type of coded signals; directing to produce the first type of coded signals of each shooting scene to obtain production information; performing director production on the second type of coded signals of each shooting scene according to the production information; and publishing the second type of coded signals of each shooting scene after director production. According to the method and the system, the switching coherence of the camera lens is ensured, and high-quality broadcasting guidance can be realized.

Description

technical field

[0001] This description relates to the technical field of cloud broadcasting, and more specifically, to a dual-coded cloud broadcasting method and system. Background technique

[0002] The OB van is produced by on-site broadcasting directors. It directly inputs multiple video baseband signals, switches or mixes them into one video stream output as required. In the existing broadcasting scene, the video signal is produced on the spot based on the baseband signal with no delay or very low delay (<10ms). According to the video signal with no delay or very low delay (<10ms) seen, the director directs the camera crew to shoot (set up the machine), and switches the broadcast to complete the production of the broadcast signal. Therefore, what the director must see is the no-delay or extremely low-latency (<10ms) images captured by the camera before directing.

[0003] With the development of cloud technology, cloud broadcasting technology is becoming more...
