Abstract
Methods and devices for encoding or decoding messages, each message including a list of information items. The encoding method comprises determining a first list of indexes associated with information items that are already indexed in a local indexing table and a second list of literal values of other information items not yet indexed in said indexing table; encoding the indexes of the first list; binary compressing at least a serialized binary representation of the literal values of the second list; and concatenating the first list and the second list together to obtain an encoded bitstream of the information items. When the messages are sent over a plurality of connections, a global table is shared between the connections to store the indexed items of information; and a local indexing table for each connection associates indexes with references to an entry of the shared global table.
