Embodiment Construction

[0024] Such as figure 1 As shown, the principle adopted in the method for automatically adjusting the call resolution provided in the embodiment of the present invention is as follows: firstly, obtain the CPU performance of the local terminal (for example, whether the main frequency of the terminal is above 1GHZ); then, determine that the current network environment is 3G It is still WIFI, so as to obtain the resolution range supported by the local terminal; then negotiate with the remote terminal of the call party to obtain the resolution range supported by the other party, and compare and choose the highest resolution acceptable to both parties. Session control adopts SIP protocol, and video encoding adopts H.264.

[0025] Such as figure 1 As shown, the local terminal provided by the embodiment of the present invention is used in the program configuration item. By default, the program intelligently selects appropriate parameters without manual operation, and achieves high-q...

Abstract

The invention provides an automatic adjustment method of resolution of a video call of an intelligent terminal. The automatic adjustment method comprises the following steps of S1, obtaining video processing capacity of a local terminal by a local client, and setting an upper limit of video resolution according to the video processing capacity of the local terminal; S2, obtaining an access manner of a local network by the local client, as for different network access manners, transmitting a negotiation message carrying different resolution information to a remote terminal by the local client; S3, receiving the negotiation message by the remote terminal, selecting the resolution matched with the local client according to a resolution format supported by the own coding and decoding capacity and the network access manner, and replying to the local client through the negotiation message. According to the automatic adjustment method of the resolution of the video call of the intelligent terminal, which is provided by the invention, the proper parameters can be selected intelligently, the proper resolution is arranged, the excellent call quality in the video call is achieved, complexity and difficulty of user operation are reduced, and the good user experience is realized.

Description

technical field [0001] The invention relates to the setting of the resolution in the video call of a mobile terminal, in particular to a method for automatically adjusting the resolution of the video call of an intelligent terminal. Background technique [0002] In today's video call products, the video resolution is usually set manually by the user, and the configuration process may involve the configuration of various parameters. This configuration method not only fails to achieve the best call quality, specifically manifested as slow speed or unclear images, but also brings additional operations to the user, resulting in poor user experience. [0003] In the process of manual parameter configuration by users, the user’s parameter settings cannot achieve the ideal call effect usually due to the following factors: first, users do not know the network conditions of both parties; second, most users do not know the specific parameters of VGA and QVGA Meaning; moreover, the us...
