Method of analyzing broadcast data, a network analyzer implementing such a method, and receiver equipment using such an analyzer

摘要

A teletext network analyzer includes a coupler for forwarding received data to a data processor. The coupler is programmable by the data processor to select data associated with one or more hierarchical levels in a data broadcasting standard. A data processor includes a data analysis task and a results synthesis task for analyzing the data forwarded by the coupler and for synthesizing a teletext image representative of the results of the analysis. The image is displayed on a videographic terminal primarily intended for displaying the broadcast data.
