Remote information processing terminal machine and method for updating audio firmware thereon

Abstract

The invention relates to a telematic terminal unit which is easy for renewing an audio firmware. The telematic terminal unit comprises: a storage part which stores the audio firmware containing different-frequency tuning information and an interface routine; and a storage medium access part used for accessing a storage medium which records the audio firmware or the storage medium which records an aural signal, and transmitting the data which is read, wherein if the aural signal is transmitted, the aural signal is analyzed, and an aural signal processing part for tone quality is tuned and played according the running conditions of the audio firmware; if audio firmware data which is accessed is transmitted, the data in the storage part is renewed, and the audio firmware runs if an audio playing command is input by the interface routine, so as to process a controlling part of the aural signal processing part. The invention has the effects that a deviser can directly operate without replacing the hardware or devices, and a common one can also realize different tone quality of various vehicles. Not only the production cost is saved, but also the audio function of the vehicle is effectively controlled.

Description

technical field [0001] The invention relates to a remote information processing terminal, in particular to a device and method for controlling audio data on a remote information processing terminal. Background technique [0002] Currently, car navigation systems are widely used, and car audio, which is regarded as an essential function, also provides various functions depending on the type of vehicle. [0003] Taking the telematics terminal as an example, it is a device that can realize complex functions including navigation function, audio function, etc., thereby providing users with convenience. The so-called telematics terminal refers to an automotive system that is organically combined with GPS (Global Positioning System: Satellite Positioning System) and mobile communication technology to provide position tracking system and remote diagnosis function. [0004] Telematics is a compound term of Telecommunications (Telecommunications) and Informatics (Informatics; Informa...

AI Technical Summary

Problems solved by technology

[0018] The disadvantage of the structure of the existing telematics terminal as described above is that in order to update the memory data installed in the above-mentioned audio control unit 135, a specific interface device such as a flash writer (flash writer) must be installed, so its The process is very complicated, and the designer needs to compare the vehicles one by one, the work is very cumbersome

[0019] In addition, even if the same navigation system is used for different types of vehicles, it is necessary to install differentiated car audio devices in order to apply different sound quality tuning values
