FIELD: physics; communication.
SUBSTANCE: invention relates to communication networks, and particularly to electronic service guides used in communication networks. The technical result is achieved due to that, when transmitting electronic service guide ESG fragments, identifier (ID) values are processed and compared, as well as the version and/or uniform resource identifier (URI) associated with ESG fragments for transmission. ESG fragments are encapsulated into an electronic service guide delivery unit (SGDU) based on processing and comparing values. Similarly, the SGDU can be received in a receiver, data associated with ID values, version and/or URI of the SGDU, and associated ESG fragments can be extracted and compared with already stored values. The SGDU and ESG fragments can be processed in accordance with comparison results.
EFFECT: identification of ESG fragments with small amount of service information.
