Embodiment Construction

[0031] Below we will describe the embodiments of the present invention in detail with reference to the accompanying drawings.

[0032] see figure 1 , which is a flow chart of an IPTV-based orientation display method provided by an embodiment of the present invention; the method includes:

[0033] Step 101: Obtain local location information and destination location information that the user needs to point to from the IPTV system;

[0034] Step 102: Obtain the current geomagnetic declination from the indicating device, and obtain the address information of the indicator light in the direction of true north in the current indicating device according to the current geomagnetic declination;

[0035] Wherein, the indicator light may be a Light Emitting Diode (LED, Light Emitting Diode) light, or a display or a display screen integrated with an LED light, of course, it may also be other light emitting devices, which are not limited in this embodiment.

[0036] Step 103: Calculate a...

Abstract

The invention relates to an internet protocol television (IPTV)-based azimuth display method, a set-top box and an IPTV-based azimuth display system. The method comprises the following steps of: acquiring local position information and destination position information to be pointed by a user from an IPTV system; acquiring a current geomagnetic declination from an indicating device, and acquiring address information of an indicating lamp of the north direction in the current indicating device according to the current geomagnetic declination; performing calculation according to the local position information, the destination position information and the address information of the indicating lamp of the north direction in the current indicating device to acquire address information of an indicating lamp corresponding to the destination position information; and controlling the corresponding indicating lamp to display the address information according to the address information of the indicating lamp corresponding to the destination position information. The problem that an electronic compass points any specific direction is solved with low cost.

Description

technical field [0001] The present invention relates to the technical field of terminal communication, in particular to an azimuth display method based on network television, a set-top box and a system. Background technique [0002] With the development of science and technology, the electronic compass can realize the function of a common compass (compass), but the general electronic compass can only point to a fixed direction, that is, south, and its principle is mainly to measure the earth's magnetic field. Since the earth's magnetic field is a weak magnetic field, at present, anisotropic magnetoresistive sensors (such as AMR) can meet the requirements for measuring the earth's magnetic field. However, due to the difference between the earth's magnetic field and the geographical north and south poles, the electronic compass can also provide the angle between the actual location and the direction of true north. [0003] However, in the current prior art, the following meth...
