Problems solved by technology

The current video communication usually uses a fixed transmission format to transmit video data. When the network type changes, transmitting video data in this way not only consumes a large amount of data traffic, but also causes the video image to have low definition. , and even cause the screen to freeze
[0007] Further, since the configurations of the two mobile terminals participating in the video communication are different, for example, the resolutions of the display screens are different, and the resolutions of the cameras are different, which may cause the camera of a mobile terminal performing video communication The resolution of the device does not match the resolution of the display screen of the peer mobile terminal
As a result, the video image is not fully displayed on the peer display, or even cannot be displayed because it is not supported by the peer display

Embodiment 2

[0090] Embodiment 2, weighted average method. Specifically: the weight of terminal information or network information is pre-stored in the storage unit, and for multiple information collected, such as terminal information or network information, according to the preset weight, the weighted average value of all collected information is calculated, and stored in the storage unit A mapping table is also pre-stored in the unit, and the mapping table records the corresponding relationship between the weighted average value and the video parameters. When the weighted average value is known, the required video parameters can be obtained by looking up the table.

Embodiment 3

[0091]Embodiment 3, priority method. The comparison priority is pre-stored in the storage unit. According to the preset priority order of the terminal information and the network information, the collected information is compared one by one with their respective reference thresholds one by one. For the corresponding reference threshold, when the comparison result is smaller than the corresponding threshold, the video parameter is obtained from the pre-stored mapping table according to the mapping relationship between the information whose value is smaller than the corresponding reference threshold and the video parameter. For example, for information such as network type, network throughput, motherboard operating frequency, motherboard temperature, battery power, and available dynamic memory capacity, the order of priority for comparison is battery power, network throughput, and available dynamic memory capacity. Dynamic memory capacity, network type, motherboard temperature, ...

Abstract

The invention discloses a video communication method and device. The method comprises the following steps of collecting terminal information and network information; obtaining a first video parameter according to at least one of the terminal information and the network information; carrying out video recording according to the first video parameter; and carrying out video transmission according to the first video parameter. The device comprises an information collection module used for collecting the terminal information and the network information, a video parameter obtaining module connected to the information collection module and used for obtaining the first video parameter according to at least one of the terminal information and the network information, a video recording module connected to the video parameter obtaining module and used for carrying out video recording according to the first video parameter, and a transmission control module connected to the video parameter obtaining module and the video recording module and used for carrying out video transmission according to the first video parameter. According to the video communication method, recording and transmission of the video can be adaptively adjusted according to the state of the terminal and the access network, so that the quality of video communication is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a video communication method and device. Background technique [0002] With the development of communication technologies, terminals no longer only provide voice services, and video communication has increasingly become a method used by users. [0003] Video communication usually refers to: a communication method based on the Internet and mobile Internet (such as 3G Internet) to transmit human voice and images (such as human busts, photos, objects, etc.) in real time between terminals. According to different terminals, video communication is generally divided into four ways: PC-to-PC, PC-to-Phone, Phone-to-PC and Phone-to-Phone via Internet. [0004] When performing video communication, there are two critical components that affect the quality of video communication: the camera and the display screen. The camera collects video data, and the microphone collects audi...
