Embodiment Construction
[0045] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
[0046] At present, there are some set-top boxes on the market that can simultaneously receive high-definition terrestrial digital signals, cable digital signals and satellite positioning signals, but there is no solution for finely locating the boundary of a certain area (such as the boundary line corresponding to the map). Specifically, in the prior art, it is impossible to locate t...

The embodiment of the invention is suitable for the technical field of information, and provides a positioning method, a signal processing method and digital video conversion equipment, and the signalprocessing method comprises the steps: receiving a positioning signal transmitted by a positioning satellite, and receiving a satellite television signal transmitted by a live broadcast satellite; analyzing the positioning signal to obtain longitude and latitude information of the current position; and matching the longitude and latitude information with preset map data, and determining an area to which the current position belongs, the map data being a data set including a plurality of position points of at least one area; and processing the satellite television signal according to the areato which the current position belongs. According to the embodiment, the analyzed longitude and latitude information is matched with the map data, so that the area to which the current position belongscan be accurately determined, and accurate positioning of the area to which the current position belongs is realized. On the basis, the embodiment of the invention can also realize accurate control of the satellite television signals in the area.
Description
technical field [0001] The application belongs to the field of information technology, and in particular relates to a positioning method, a signal processing method and a digital video conversion device. Background technique [0002] With the rapid development of science and technology, especially information technology, people's lives have already entered the era of digitalization and informationization, and the digitalization and personalization of satellite radio and television are also accelerating the layout. Although satellite TV broadcasting has been realized in most parts of the world, in some special areas, the broadcasting of satellite TV programs is still affected by factors such as national relations, geographical location, and urban-rural differences, and there are certain usage restrictions. For example, in a particular area where the current relationship is tense and complicated, the satellite TV programs of country A are not allowed to be broadcast in country...
