Embodiment Construction

[0072] In general terms, the present invention relates to an improved method of encoding data (D1) to generate encoded data D2, which method provides a higher level of encoding efficiency. The improved method is able to efficiently encode a variety of content represented by the data to be encoded (D1), such as still images, video content, image content, audio content, ECG (electrocardiogram), seismic data etc.

[0073] see figure 1 , which provides a schematic diagram of an encoder 10 for encoding data 20 (D1) using the method of the present invention. The encoder 10 generates encoded data 70 ( E2 ), which is stored and / or streamed for subsequent decoding in one or more decoders 25 . One or more decoders 25 generate corresponding decoded data 75 (D3) for use by one or more users. The decoded data 75 (D3) optionally substantially corresponds to the unencoded data 20 (D1). The combination of at least one encoder 10 and at least one corresponding decoder 25 forms a data commu...

Abstract

An encoder encodes input data to generate corresponding encoded output data. The encoder includes an analysis unit for analysing a portion of the input data and directing the portion to appropriate encoding unit(s), wherein the encoding unit(s) are operable to encode the portion thereat to generate the encoded output data. At least one of the encoding units is operable to compute an average value of data values present in each portion received thereat, to subdivide the data values into at least two sets, to compute average values of the data values in each set, and for each set to allocate the average value for that set to all data values in that set, whilst retaining a spatial mask of the portion, and wherein the spatial mask and information representative of the average values computed for the at least two data sets is included in the encoded output data.

Description

technical field [0001] The invention relates to an encoder for encoding data (D1) corresponding to a plurality of contents, which may be still images, video contents, graphic contents, audio contents, measurement data, to generate corresponding encoded data (E2) etc. The invention also relates to an encoding method for encoding data (D1) corresponding to a plurality of contents, which may be still images, video contents, graphic contents, audio contents, measurement data and so on. Furthermore, the invention relates to a decoder for decoding the data (E2) in encoded format produced by the aforementioned encoder. The invention also relates to a method of decoding the data (E2) generated by the aforementioned encoder. Further, the present invention also relates to a software product recorded on a non-transitory machine-readable data storage medium, wherein the software product is executed on computing hardware to implement the above method. Background technique [0002] Th...
