The container according to claim 1 , wherein the code further comprises an end portion for identification of an end of the data sequence, the end portion comprising a marker and a marker location at the end of the data sequence, wherein a distance X3 therebetween is distinct from: the distance X1; the distance Δx; and when dependent on the directly preceding claim the X4 distance.

5. The container according to claim 1 , wherein the markers of the code are arranged sequentially to each other and radially on a single circumferentially extending line, which extends about an axis of rotation of the container or other rotational axis on a surface thereof.

6. The container according to claim 1 , wherein the markers of the code are formed by electrically conductive portions.

7. The container according to claim 1 , wherein the code is formed on a surface of the container or on an attachment, which is attached thereto.

8. The container according to claim 1 , wherein the container comprises at least one of the following:

a capsule;

a packet; and

a receptacle for consumption of the beverage or foodstuff therefrom.

9. A beverage or foodstuff preparation machine, said preparation machine comprising:

a preparation unit to receive a container and to prepare a beverage or foodstuff therefrom, wherein the container comprises a code encoding preparation information, and wherein the code comprises:

a data sequence having a plurality of marker locations, whereby said marker locations either comprise or do not comprise a marker as a variable to at least partially encode the preparation information therein, with adjacent marker locations separated by a distance of Δx;

a calibration sequence having two adjacent markers with a distance of X1 therebetween;

whereby the distance Δx between adjacent marker locations of the data sequence is related to the distance X1 of the calibration sequence; and

a locator sequence to enable location of the data sequence or calibration sequence, the locator sequence comprising two adjacent markers, whereby a distance X4 therebetween is distinct from the distance X1 and is distinct from the distance Δx;

a code processing system operable to read a code of said container or an attachment of the container or the machine to obtain encoded preparation information and process the encoded preparation information to decode said information; and

a control system operable to control the preparation unit using said decoded preparation information;

wherein the code processing system is configured to process the encoded preparation information to locate one or more code reads therein by locating markers that are a predetermined distance X4 apart, and for each located code read(s), the code processing system is further configured to:

locate the calibration sequence and determine therefrom the distance X1;

determine a distance Δx between adjacent marker locations of the data sequence using said determined X1 distance; and

determine, using said Δx distance, the presence of a marker at each marker location of the data sequence.

10. A beverage or foodstuff preparation system comprising:

a container for containing beverage or foodstuff preparation material and comprising a code encoding preparation information, wherein the code comprises:

a data sequence having a plurality of marker locations, whereby said marker locations either comprise or do not comprise a marker as a variable to at least partially encode the preparation information therein, with adjacent marker locations separated by a distance of Δx;

a calibration sequence having two adjacent markers with a distance of X1 therebetween,

whereby the distance Δx between adjacent marker locations of the data sequence is related to the distance X1 of the calibration sequence; and

a locator sequence to enable location of the data sequence or calibration sequence, the locator sequence comprising two adjacent markers, whereby a distance X4 therebetween is distinct from the distance X1 and is distinct from the distance Δx; and

a beverage or foodstuff preparation machine, comprising:

a preparation unit to receive the container and to prepare a beverage or foodstuff therefrom;

a code processing system operable to read a code of said container or an attachment of the container or the machine to obtain encoded preparation information and process the encoded preparation information to decode said information; and

a control system operable to control the preparation unit using said decoded preparation information;

wherein the code processing system is configured to process the encoded preparation information to locate one or more code reads therein by locating markers that are a predetermined distance X4 apart, and for each located code read(s), the code processing system is further configured to:

locate the calibration sequence and determine therefrom the distance X1;

determine a distance Δx between adjacent marker locations of the data sequence using said determined X1 distance; and

determine, using said Δx distance, the presence of a marker at each marker location of the data sequence.
