摘要： An method for encoding comprising: obtaining, according to a data length of an overlapped portion between encoding data of a current frame and encoding data of a previous frame, encoding data corresponding to the data length of the overlapped portion from the previous frame if the previous frame is encoded in a first encoding mode and the current frame is to be encoded in a second encoding mode; and encoding, in the second encoding mode, the obtained encoding data corresponding to the data length of the overlapped portion from the previous frame and encoding data of the current frame to obtain an encoding result. The corresponding decoding method, encoding and decoding apparatuses are also disclosed.

摘要： A frame compensation method is provided. The method includes the following steps: obtaining a length of a lost frame and a length of a correct frame; determining that the length of the correct frame is integral power of 2 times of the length of the lost frame, and then obtaining a data sequence with the same length as the length of the lost frame according to the correct frame; and compensating the lost frame according to the data sequence to obtain a compensated data frame. A frame compensation system is also provided. The system includes: a first length obtaining module, a second length obtaining module, a data sequence obtaining module, and a compensation module. Lost frames in various formats are compensated according to correct frames in various formats, so that the limitation of the related art that a lost frame in a single format can be merely compensated according to a correct frame in a single format is eliminated, and the effect of the compensated data frames is better than that of filling comfort noises.
摘要翻译：提供帧补偿方法。该方法包括以下步骤：获得丢失帧的长度和正确帧的长度; 确定正确帧的长度是丢失帧的长度的2倍的整数倍，然后根据正确的帧获得与丢失帧的长度相同的长度的数据序列; 并根据数据序列补偿丢失帧以获得补偿数据帧。还提供了帧补偿系统。该系统包括：第一长度获取模块，第二长度获取模块，数据序列获取模块和补偿模块。各种格式的丢帧按照各种格式的正确帧进行补偿，因此消除了相关技术的限制，即单个格式的丢失帧只能根据单个格式的正确帧进行补偿，并且效果的补偿数据帧比填充舒适噪声好。
