Encoding data arrays

A data array is coded. When encoding a stream of a data element array or a data element array, an encoder comprising an encoding circuit is used (32,62) which can work to encode the array of data elements as a plurality of independent segments, wherein, each of the independent segments being independently decodable; generating a header that is output together with a encoded data stream comprisinga plurality of independent segments. (14), wherein the header comprises an encoded data stream indicating each of the plurality of independent segments (20), and the information of the position in theposition. The encoded data stream associated with such a header is to be decoded (20) so that the decoder can read the header to identify the independent segment in the data stream (20), and then reading and decoding the identified segment from the identified location in the data stream. 对数据阵列进行编码。当对数据元素阵列或数据元素阵列的流进行编码时，使用包括编码电路的编码器(32、62)，该编码电路可进行工作以将数据元素阵列作为多个独立段进行编码，其中，各独立段可以被独立解码；生成与包括多个独立段的编码数据流(20)一起输出的报头(14)，其中，该报头
