    • The present application relates to a method for embedded video compression comprising receiving image data. The method comprises compressing the image data into compressed data blocks with a predefined data rate by using a video compression mode. The method comprises compressing the image data into compressed data blocks with the predefined data rate by using a graphic compression mode, wherein the predefined data rate defines a target code size of a compressed data block. The method comprises detecting whether a code size of the data block does not meet the target code size. The method comprises quantizing at least one input pixel of the image data in case a code size of the data block does not meet the target code size. The present application relates also to a method for embedded video decompression, an apparatus for embedded video compression and an apparatus for embedded video decompression. Furthermore the present application relates to a system comprising said apparatus for embedded video compression and said apparatus for embedded video compression and to a computer readable medium having a computer program stored thereon for performing said method for embedded video compression and said method for embedded video decompression.
    • 本申请涉及一种用于嵌入式视频压缩的方法,包括接收图像数据。 该方法包括使用视频压缩模式将图像数据压缩成预定数据速率的压缩数据块。 该方法包括使用图形压缩模式将图像数据压缩成具有预定数据速率的压缩数据块,其中预定数据速率定义压缩数据块的目标代码大小。 该方法包括检测数据块的代码大小是否不满足目标代码大小。 该方法包括在数据块的代码大小不满足目标代码大小的情况下量化图像数据的至少一个输入像素。 本申请还涉及嵌入式视频解压缩方法,嵌入式视频压缩装置和嵌入式视频解压缩装置。 此外,本申请涉及一种包括所述用于嵌入式视频压缩的装置和所述用于嵌入式视频压缩的装置的系统,以及具有存储在其上的计算机程序的计算机可读介质,用于执行所述嵌入式视频压缩方法和所述嵌入式视频解压缩方法。
