摘要： A video encoding decoding method and device and a video codec are provided. The video encoding method includes the following steps. A first view picture is basic-layer encoded as a reference view picture, prediction information is extracted in combination with a second view picture, and the second view picture is re-created. A residual value is calculated according to a re-created second view picture and the original second view picture. When the residual value is greater than a threshold, both the residual value and the prediction information are enhanced-layer encoded simultaneously; otherwise, only the prediction information is enhanced-layer encoded. Encoded information is obtained by multiplexing the enhanced-layer encoding with the basic-layer encoding of the first video picture. The video decoding method includes the following steps. After de-multiplex, basic-layer encoded information and enhanced-layer encoded information are decoded respectively to obtain a first view picture, prediction information, and a residual value, and then a second view picture is re-created. The embodiments of the invention can realize the effective compression of stereo video data, reduce an encoding complexity, and are compatible with the conventional two dimensional displaying, so as to correctly and easily re-create a stereo view picture.
摘要翻译：提供视频编码解码方法和设备以及视频编解码器。视频编码方法包括以下步骤。第一视图图像被基本层编码为参考视图图像，与第二视图组合提取预测信息，并且重新创建第二视图图像。根据重新创建的第二视图图像和原始第二视图图像来计算残差值。当残差值大于阈值时，残差值和预测信息同时增强层编码; 否则仅增强层编码预测信息。通过将增强层编码与第一视频图像的基本层编码进行复用来获得编码信息。视频解码方法包括以下步骤。在解复用之后，分别对基本层编码信息和增强层编码信息进行解码以获得第一视图图像，预测信息和残差值，然后重新创建第二视图图像。本发明的实施例可以实现立体视频数据的有效压缩，降低编码复杂度，并且与常规二维显示兼容，以便正确且容易地重新创建立体视图图像。
