摘要
The method involves transmitting an event i.e. change of service transmission parameter, before being notified at a short period within a flux of descriptor table, where the parameter e.g. frequency of transmission, is transmitted by a radiodiffused digital services transmission apparatus. The table is transmitted in the form of notification section inserted into certain bursts emitted between data sections and error correction sections, where the section contains information relative to moment of flow of data transmission of service or services conforming to a new parameter. Independent claims are also included for the following: (1) a method for receiving a notification of an event before being notified at short time by a service receiving apparatus (2) a device for transmitting radio diffused digital services at destination of receiving apparatus, comprising a transmitting unit (3) a device for receiving a service emitted by a radio diffused digital services transmitting apparatus, comprising a receiving unit (4) a data structure to be transmitted by a radio diffused digital services transmitting apparatus to destination of receiving apparatus.
