Abstract
Disclosed is a method for ensuring the integrity of a container to be transmitted to a Digital Video Broadcasting-Handheld (DVB-H) terminal. A DVB-H server divides a container in which data required to deliver broadcasting information is included into one or more sections, extracts a Cycle Redundancy Check (CRC) value related to data of each section, and then creates profile information of the container. The created profile information of the container is used to check the integrity of the container, and is transmitted following the addition of the created profile information to a header part of the container. Hence, the terminal compares data of an actually received container with data of a container which has to be received on the basis of the profile information related to the container, and determines if the data included in the container is lost.
