Station search method based on digital audio signal recognition

Abstract

The invention relates to a station search method based on digital audio signal identification, including the steps of station cycle search and station playback; the station search includes the following steps: 1) locking the station and obtaining the corresponding digital audio signal of the station; After the audio signal is identified by the radio content and classified based on the type of audio content, the radio identification result is obtained; 3) The radio identification result after step 2) is saved and displayed through the radio selection module; 4) The radio is controlled based on the radio scanning range Scan and switch, re-lock the new station and repeat steps 1) to step 3); the station playback means that when the user needs to select a station to listen to, select the corresponding station from the station identification results in the station selection module according to the demand, through Lock the station and play back the acquired digital audio signal of the station. The method of the invention allows the user to directly select a desired radio station to receive and listen to, thereby improving user experience.

Description

technical field [0001] The invention relates to the technical field of station search, in particular to a station search method based on digital audio signal identification. Background technique [0002] At present, the technology of station search mainly focuses on the following three aspects: 1) how to lock the best frequency of the channel; 2) how to automatically select the station under the known station name or station attribute (such as RDS system); for example, apply No. 200810177411.2 invention patent, which provides an RDS receiver and its receiving method, which can reduce automatic tracking switching actions such as useless AF search. The RDS receiver, which receives RDS broadcasts, is characterized in that it has: a receiving state detection unit, which detects the received receiving state of the RDS broadcast; a receiving state judging unit, which judges the level of the detected receiving state; and a control unit , corresponding to the level, perform an auto...

Problems solved by technology

[0004] However, at present, for many situations where the content of the radio station and the attributes of the current program of the radio station cannot be obtained directly, the user needs to perform complex processes such as receiving, auditioning, and changing stations one by one when actually listening, and even the desired station has not been found after the search.
