Method and electronic device for decoding a data stream, and associated computer program and data streams

An electronic device comprising:

• at least one processor;
• and
• at least one non-transitory computer readable medium comprising program code instructions stored thereon which when executed by the at least one processor configure the electronic device to:
• obtain a data stream, including a plurality of identifiers, a sequence of binary elements and an indicator indicating a start of the sequence of binary elements within the data stream;
• and
• decode the obtained data stream into a sequence of data of respective predetermined types, the decoding comprising obtaining at least one piece of data of said sequence of data by:
• determining a context based on an identifier, from among the plurality of identifiers, that is associated with the respective type of the respective piece of data;
• identifying the start of the sequence of binary elements from the indicator;
• and
• decoding a part of the sequence of binary elements by using an entropy decoder receiving the sequence of binary elements as an input and parameterized in the determined context.
