The invention discloses a method and a system for realizing interactive data. The method comprises the following steps: S1, data collection templates are made; S2, data are collected and acquired from different platforms, and according to different templates, data of the different platforms are converged; S3, interactive data are stored to a data storage disc of a data collection workstation; S4, the interactive data are transmitted and stored to a data storage disc of a data selection workstation; S5, a serial sheet is built, and a well-made data matching template is selected from a model library; S6, interactive data selected from an interactive teletext library are dragged to the serial sheet to be correlated to entries in the serial sheet, and are matched with a selected template; S7, data in need of adjustment are subjected to teletext parameter adjustment; S8, a data interactive sheet is generated; S9, the interactive sheet is transmitted and stored to a data storage disc of a data broadcasting workstation, dynamic resources of the interactive sheet are transmitted to be synchronized with the interactive data of an audience, and real-time updating is ensured; and S10, the interactive sheet is analyzed to be broadcasted to a live program.
