Abstract

The invention discloses an image resizing method and system of a double-current video conference terminal. The method comprises the steps that when a current video conference terminal receives the request of a user for terminal image resizing, the current video conference terminal sends the request to a local resizing control unit; the resizing control unit judges whether a remote video conference terminal has the image resizing function and sends the request to a local decoding unit if the remote video conference terminal does not have the image resizing function; all or part of decoded image information is displayed on the current video conference terminal by the decoding unit according to resizing identification and resizing area coordinates included in the request. According to the image resizing method and system of the double-current video conference terminal, the part, of interest to the user, of a double-current image can be obtained by controlling the video conference terminal located at an image receiving end or at an image sending end, and then the part of the double-current image can be displayed in a zoom-in mode to enable the user to observe the details of the image.

Description

technical field [0001] The invention relates to the communication field, in particular to an image scaling method and system for a dual-stream video conferencing terminal. Background technique [0002] Video conferencing is mainly to establish face-to-face communication between remote terminals in the form of voice and video. With the increasing application of conferencing systems, people are not satisfied with just seeing remote video images, but hope to see more information, such as charts, data or documents used in meetings, which are usually Stored in the computer in the form of data files. Therefore, in many occasions, such as remote conferences, distance education, remote office, etc., it is required to establish a collaborative work between video and data in video conferences to enhance the sense of presence and improve conference efficiency. [0003] The existing dual-stream technology can meet the above requirements. Dual-stream technology actually refers to dual ...
