The invention discloses a traffic information broadcasting device and method which are used in a vehicle-mounted multimedia system. The device comprises an antenna, a signal receiving unit used for receiving a broadcasting signal, a signal selection unit used for selecting a broadcasting signal at a specific frequency, a signal analytical unit used for analyzing the broadcasting signal, a data processing unit which is used for responding an operation request from a user and processing the analyzed broadcasting signal, a loudspeaker and a display screen which are connected with the data processing unit, as well as a state acquiring unit used for acquiring the working state of the current vehicle-mounted multimedia system and a priority unit used for storing priority order of various working states of the vehicle-mounted multimedia system. According to the device disclosed by the invention, when the vehicle-mounted multimedia system is in a working state, whether the current TA (traffic announce) information or other traffic information is broadcast is judged by comparing the priority and follow-up operation is carried out, and thus the effect of obviously improving user experience is achieved.
Description
technical field [0001] The invention relates to the technical field of vehicle-mounted multimedia, in particular to a device and method for broadcasting traffic information used in a vehicle-mounted multimedia system. Background technique [0002] With the development, more and more radio stations have RDS broadcast function. In addition to listening to radio programs, RDS can also display other information such as station name, program type, program content, date and time. RDS has been designed for vehicle mobile from the beginning. , so many features of RDS are related to the mobile environment, such as Traffic Announcement (TA) and Switching Frequency (AF) functions. The TA function provides the driver with relevant information on the current traffic conditions. When traffic jams or major traffic accidents occur, such as car accidents, landslides, etc., the RDS radio station with the TA function will send information containing the above traffic conditions. At this time, ...
