Patent number: 10869048Abstract: Embodiments of this application disclose a picture transmission method performed at a computer device. After obtaining a picture, the computer device generates a video sequence by replicating the picture N times, and N being a positive integer. Next the computer device obtains a resolution setting sequence and encodes the N to-be-encoded pictures in the video sequence according to the resolution setting sequence to generate N encoded pictures, each encoded picture having an associated resolution setting. Finally, the computer device sends the N encoded pictures to a decoding computer device. The decoding computer device then decodes and displays the N encoded pictures according to their respective resolution settings from low to high.Type: GrantFiled: August 20, 2019Date of Patent: December 15, 2020Assignee: TENCENT TECHNOLOGY (SHENZHEN) COMPANY LIMITEDInventors: Xunan Mao, Xinwei Gao, Tao Zhang, Licai Guo, Yongfang Shi, Anlin Gao, Haibo Deng, Yaoyao Guo, Chenchen Gu, Jian He, Jing Lv
