Abstract

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.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a method, device and system for realizing broadcast service grouping. Background technique [0002] In order to meet the needs of digital conversion of the Cable TV system, the cable operators in North America have introduced simple set-top box terminal products such as Digital TV Adapter (DTA) to realize the reception and conversion of digital TV signals. For such simple set-top box products, the system control management method is generally relatively simple, and the control system scheme is simple. It provides an economical solution for low-end users who do not need complicated broadcasting services, and reduces deployment costs. [0003] Because the system is simple in structure, it does not consider individual broadcast service group authorization management for each user, so it also determines that it can only provide simple services to users, and cannot realize broadcast ...
