Problems solved by technology

For example, it is necessary to add additional circuits with related functions in the mobile playback device, resulting in additional overhead
Furthermore, due to the relationship of GPS signal transmission, there is a dead angle for the use of indoor environment, and not every mobile wireless TV viewing device has the GPS signal receiving function, so it is still inconvenient to use in some environments.

Embodiment Construction

[0032] To this end, the present invention is based on the Taiwan Patent Application 096146599, and further proposes the use of mobile communication systems, such as mobile phone communication systems or wireless network systems to obtain positioning. Since the definition of the frequency correspondence of wireless broadcasting systems depends on different regions Definition. Therefore, for mobile playback devices, the purpose of providing positioning is as long as it can provide information about the location without precise positioning of the location. In other words, the accuracy of the positioning information here only needs to be accurate enough to obtain the frequency information table of the corresponding area, so the relative error tolerance is also high.

[0033] Based on this concept, the present invention proposes to locate the mobile phone through the base station in the mobile phone communication system, or obtain the information of the area through the wireless networ...

Abstract

The invention discloses a mobile playing method and a mobile playing device, which are applied to a mobile playing device with wireless broadcast receiving function. The mobile playing device plays according to the following steps: first position information is obtained through the connection with a mobile communication system, so a first information table is chosen from a plurality of information tables, a first frequency range is chosen from a plurality of playing frequency ranges in the first information table, a first wireless broadcast signal is received according to the first frequency range and channel content thereof is played, when the mobile playing device is moved, second position information is obtained through the mobile communication system, so a second information table is chosen from a plurality of information tables and after a second frequency range is obtained from the second information table, a second wireless broadcast signal is received according to the second frequency range and channel content thereof is played. The invention can improve the convenience of the mobile playing device.

Description

Technical field [0001] The present invention relates to a mobile broadcasting device and method for wireless broadcast programs, and in particular to a mobile broadcasting device and method for providing location information through a mobile communication system. Background technique [0002] The current wireless broadcast programs and digital TV programs all send radio waves through wireless transmitters, and then pair them with general antennas or corresponding wireless signal receiving devices to convert the received signals into audio-visual content for users to listen to or watch. [0003] Take digital TV as an example. Because the picture quality is clearer than that of traditional cable TV, and it does not require monthly fees and is mobile, it has become more popular in recent years. Due to the mobility of the transmission and reception of digital TV programs, related mobile playback devices are also used in vehicles or when users are not using them at fixed points. [0004]...
