Device and method for detecting telephone number information from digital multimedia broadcasting in digital multimedia broadcasting receiving terminal

摘要

Disclosed is a device and method for detecting telephone number information from DMB in a DMB receiving terminal. If DMB data is received, the present invention scans I-frame data from among the received DMB data, and detects an ROI from the scanned data. If the ROI is detected, the present invention binarizes the detected ROI, and extracts a numeral region from the correspondent ROI while passing through processes of removing a non-text region from the binarized ROI and partitioning a character string region and characters of the correspondent ROI. Blobs extracted from the extracted numeral region are recognized as numerals, combines telephone numbers using the recognized numerals, stores and outputs them. A user can obtain a telephone number broadcasted in the DMB without changing a general DMB data transmission/reception process, and receive services provided according thereto.
