Video focus content transmission system and method

Abstract

The invention discloses a video focus content transmission system and method. The system comprises a data acquisition unit, a sending end data processing unit, a server unit and at least one path of user receiving end which are connected in sequence, wherein each path of user receiving end comprises a receiving end data processing unit, a playing unit in interactive communication with the corresponding receiving end data processing unit and a focus selection unit in connection communication with the playing unit; and the focus selection unit selects a focus area of interest on the panoramic image displayed by the playing unit, amplifies the focus area, and plays the amplified focus area image through the playing unit. According to the invention, a video receiving end user can randomly select a concerned content area to amplify, the amplified video can select different modes according to needs, and a user having a requirement on image quality can select a high-definition mode.

Description

technical field [0001] The present invention relates to a video transmission system, in particular to a video focus content transmission system and method capable of zooming in and switching focus content in a picture. Background technique [0002] At present, with the development and popularization of Internet technology, video chat (including video conferencing and live broadcast) is widely used in people's daily life and work, which enhances the convenience of living and working in different places and is widely used. Video screen transmission is a multimedia communication technology, which is characterized by real-time transmission of communicators' images, sounds and other information such as conference materials and physical images. In the video chat, the video capture side is defined as the sender, and the viewing side is defined as the receiver. The main implementation principles are as follows: figure 1 As shown, the data acquisition equipment is responsible for co...

Problems solved by technology

In the current video transmission method, the receiving end cannot arbitrarily select the partial image that needs to be enlarged. If the receiving end performs partial enlargement on the received image information, the resolution and image quality can only be sacrificed. At the same time, the panoramic image and partial image cannot enjoy the same image quality. The user experience is poor, and the current video transmission can only zoom in on a certain area of ​​​​the receiving end image, and the viewing flexibility is poor

Therefore, the current video transmission technology has poor user experience
