A realization method, device and system for broadcast service grouping are provided. The method includes: receiving, by a terminal, at least one virtual channel table delivered by a network side, where the virtual channel table includes a first checksum and a data object that are generated by the network side, and the data object includes channel information; using a preset broadcast service group identifier and the data object of the virtual channel table to acquire a second checksum of the preset broadcast service group identifier and the data object of the virtual channel table; and acquiring a virtual channel table that passes check from the at least one virtual channel table delivered by the network side, when the first checksum matches the second checksum. According to the embodiments of the present invention, authorization of services according to levels and groups may be realized based on a simplified control system, a deployed terminal is limited to being only capable of receiving basic programs in a case that software is not upgraded, while a subsequently released terminal may receive channel information of a service group to which the subsequently released terminal belongs. The subsequent released terminal is a terminal equipped with checksum computation and check capabilities. |
