Embodiment Construction

[0023] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In the following description, even if the same elements are shown in different drawings, they are denoted by the same reference numerals. Also, in the following description of the present invention, a detailed description of well-known functions and configurations incorporated herein will be omitted when it may make the gist of the present invention unclear.

[0024] First, in order to further understand the present invention, the basic principle of the present invention will be described. In the present invention, if Digital Multimedia Broadcasting (DMB) data is received, I frame data is decoded in the received DMB data. Furthermore, the decoded I-frame data is scanned, and a region of interest (ROI) is detected from the scanned data. Here, the ROI refers to a portion of the display area selected according to a preset condition in an object area,...

Abstract

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.

Description

technical field [0001] The present invention relates to digital multimedia broadcasting (DMB), and more specifically, to a DMB receiving terminal. Background technique [0002] In general, Digital Multimedia Broadcasting (DMB) refers to broadcasting services for providing high image quality, high sound quality, and advanced services to users instead of analog broadcasting. Furthermore, with the development of DMB and mobile communication technologies, interest in a DMB service for enabling DMB to be viewed and listened to while a DMB receiving terminal is moving has grown. Therefore, a non-directional DMB receiving antenna has been attached to a mobile communication terminal so that DMB can be received through the mobile communication terminal. [0003] In order to improve the user's convenience in such a general DMB, a telephone number can be inserted into the broadcast to support information communication, product sales, etc. at the same time as the broadcast, so that the...
