摘要： Since joint scalable video coding (JSVC) adopts a scheme in which numbers are assigned to all of the pictures according to the order in which the pictures are displayed, it is difficult to detect a drop (or loss) of a key picture and thus it is difficult to effectively take action against an error caused by the loss of the key picture. The present invention provides a coding method of detecting a loss of a key picture by numbering key pictures in JSVC in which predictive (P) pictures have a closed-loop structure and of effectively taking action against an error in the case of a loss of a key picture, and a codec using the coding method. The SVC method includes performing encoding while assigning a number to a key picture of an upper layer and performing decoding with respect to the number-encoded current key picture of the upper layer using data of a decoded image of a picture of a lower layer that is temporally matched with the current key picture of the upper layer when a loss of a key picture between the number-encoded current key picture of the upper layer and a previous key picture that is number-encoded prior to the current key picture is detected. Therefore, it is possible to effectively take action against to an error caused by a loss of a key picture by detecting the loss of a key picture during decoding by encoding using numbering of key pictures in JSVC in which closed-loop coding is performed by consecutively predicting key pictures. Moreover, it is possible to minimize degradation in image quality by concealing an error caused by an incorrect reference by using data of a decoded image of a corresponding picture of a lower base layer when a key picture of an upper layer is lost in an environment where transmission of the lower base layer is guaranteed with a video stream having a multi-layered structure.
摘要翻译：由于联合可缩放视频编码（JSVC）采用根据图像显示顺序将数字分配给所有图像的方案，因此难以检测到关键图像的下降（或丢失），因此它难以有效地采取行动打击由于失去关键图片而造成的错误。本发明提供了一种通过对JSVC中的关键画面进行编号来检测关键画面的损失的编码方法，其中预测（P）画面具有闭环结构，并且在丢失了关键图片和使用编码方法的编解码器。 SVC方法包括在向上层的关键图像分配数字的同时执行编码，并且使用下层的图像的解码图像的数据来执行关于上层的编号编号的当前密钥图像的解码当检测到在上一层的编号编码的当前关键图像与在当前关键图像之前被编码的先前的关键图像之间的关键图像的丢失时，与上层的当前关键图像暂时匹配。因此，通过在JSVC中通过使用编码密钥图像进行编码的解码期间通过检测密钥图像的丢失而有效地采取对由于密钥图像丢失引起的错误的动作，其中连续执行闭环编码预测关键图片。此外，当在上层的关键图像丢失时，通过使用下基层的对应图片的解码图像的数据，在由于不正确的参考引起的错误隐藏的情况下，可以最小化图像质量的劣化，通过具有多层结构的视频流来保证下基层的传输。
