Video supply system and method based on scene mode and user perception demand

Abstract

The invention provides a video supply system and method based on a scene mode and a user perception demand, and solves the problems that video supply lacks user feedback and transmission resources arewasted. A user interaction sub-module receives a user demand and transmits the user demand to a server; a video quality decline judgment sub-module gives a video quality judgment result, and a codingcontrol module and a coding module jointly realize video quality adjustment. According to the method, video data acquisition, transmission and objective quality evaluation are carried out, a video supply mode is selected, and videos are supplied according to the selected mode. The video quality is adjusted according to the perception requirement and the scene mode of the user. The control mode issubjective and automatic, and the strategy is divided into dynamic and static scenes. According to the supply method, the perception requirement and the scene mode of the user are integrated, the perception experience of the user is improved, visual redundancy is reduced, and it is guaranteed that the main requirement of the user is met when transmission conditions are insufficient. Video supply.

Description

technical field [0001] The invention belongs to the technical field of video supply, and in particular relates to video supply for user-controlled supply demand, specifically a video supply system and method based on scene mode and user cognitive demand, which can be used in a video transmission system. Background technique [0002] With the update and iteration of image acquisition equipment and display equipment, the amount of data presented to users is getting larger and larger, which places higher and higher requirements on storage and transmission equipment. However, in some working environments, the transmission conditions cannot meet the transmission requirements of visual data, and the purposeless and unorganized high-definition image collection creates a huge amount of redundant data, making it impossible for users to obtain key effective data in time, resulting in a decline in experience or even Important information was missed. [0003] The human visual system is...

Problems solved by technology

However, the existing supply systems and methods cannot accurately measure the user's demand for video quality, lack the feedback of user demand, cannot feed back the user's perceived demand to the server, and cannot accurately supply video data according to the user's demand

In addition, the user's perception needs are different in the dynamic scene mode and the static scene mode. The existing supply systems and methods do not take into account the impact of the scene mode on the user's perception, and cannot accurately supply videos that meet the user's perception needs according to the scene mode. As a result, the supply of video is blind and directionless, and a large amount of visual redundant data wastes transmission resources. When the transmission conditions are poor, a large amount of redundant data will prevent users from receiving key data in time, resulting in a decline in user experience; In the case of insufficient transmission conditions, the existing transmission systems and methods lack solutions and cannot adjust the transmission requirements according to the transmission conditions. Packet and frame loss will occur, resulting in a decline in user experience, and in severe cases, key information will be missed.
