发明名称 METHOD AND DEVICE OF DATA TRANSMISSION
摘要 <p>A method for transmitting video communication data includes: allocating a redundant audio data bandwidth according to an obtained current packet loss ratio of audio data, generating redundant audio data according to the redundant audio data bandwidth, and sending the redundant audio data; calculating a target total video data bandwidth according to a video communication bandwidth, an encoded audio data bandwidth, and the redundant audio data bandwidth; allocating a redundant video data bandwidth according to an obtained current packet loss ratio of video data and the target total video data bandwidth, generating redundant video data according to the redundant video data bandwidth, and sending the redundant video data. A method for transmitting video communication data and a video communication device are also provided. By using the method and device, the quality of voices and videos is improved in the video communication, and the utilization efficiency of the communication bandwidth is guaranteed.</p>
