Description
[technical field]
The present invention relates to a kind of memory storage of play medium, especially when not being connected with the external data disposal system by communication interface, the memory storage that can play the audio frequency of its stored.
[background technology]
Development along with semiconductor memory technologies, semiconductor storage (hereinafter referred to as memory storage) because its high capacity, at a high speed, characteristics such as light and handy are widely used in the various data handling systems, this data handling system includes mobile computer, desktop PC, digital camera, mobile phone, audio player etc.In these data handling systems, memory storage is used to store Various types of data, as operating system associated profiles, types of applications system associated profiles, text archives, image file, audio file and video archive etc.
Memory storage in the data handling system can be divided into two types, a kind of is to be fixed on the memory storage of generally not changing and moving in the data handling system, as hard disk in the various computer systems (mobile computer, desktop PC etc.) and the memory storage in the audio player.And another kind of for being connected in the packaged type memory storage of data handling system by the external communication interface of data handling system, as portable hard drive and various types of flash memory devices.
Generally speaking, various memory storages have only a kind of standard communication interface of support usually, for example hard disk has generally included only a parallel communication interface (as the IDE communication interface), and portable hard drive or all kinds of flash memory devices have also included only a USB (universal serial bus) communication interface (as the USB communication interface).So each memory storage can only be used in the data handling system of supporting this kind communication interface, owing to often need to carry out the exchange of data between various data handling systems, if when a memory storage will be used on the data handling system of supporting other communication interface, need be by adapter with signaling transfer point or read write line, so not only increased user's burden, returned the user and bring a lot of inconvenience.For example, when user's out using portable data disposal system, must carry special adapter or read write line, if leave behind special adapter or read write line just can't be from memory storage reading of data.
Therefore a kind of memory storage of supporting multiple interfaces occurred, can include multiple parallel communication interface and/or serial communication interface in this memory storage, this memory storage can use in having the data handling system of different communication interfaces like this.Yet, this kind supports the memory storage of multiple interfaces still to exist deficiency to have: when this memory storage is not connected with data handling system by communication interface, memory storage can't be play the audio file of its stored, can't accomplish optimum utilization to memory storage, promptly when this memory storage is not connected with data handling system by communication interface, but can not use as the apparatus for processing audio of an independent operating.
And for general portable electron device such as media playing apparatus, it can carry out communication by a serial communication interface (as: USB (universal serial bus) communication interface) and external data processing system, but, can't directly use as a hard disk because it does not support parallel communication interface (as the IDE communication interface); And it can't play the related media archives according to the playlist that sets in the data handling system externally.
[summary of the invention]
In view of this, be necessary to propose a kind of memory storage of play medium, it can play the medium archives that are stored in the memory storage when it is not connected with the external data disposal system by communication interface.
The memory storage of above-mentioned play medium also can be stored in medium archives in the memory storage according to user's hobby or shuffle.
Above-mentioned memory storage also can use as mobile briefcase when it is connected with the external data disposal system by serial communication interface.
The memory storage of described play medium, it includes a storage unit, is used to store data, and these data include medium archives, default playlist and a media list; At least one communication interface comprises a parallel communication interface, is used to be connected in external computer system, makes this memory storage directly use as the hard disk of outer computer; One control panel is located at the appropriate location of this memory storage, and this control panel is used for operating the generation control signal according to the user; And a processing unit, be connected this control signal of response with a DCU data control unit to this medium archives decoding output by an internal control interface.
The memory storage of described play medium further includes following feature: when this control signal was the shuffle signal, this processing unit produced shuffle tabulation at random according to this media list and in regular turn this medium archives decoding is exported; When this control signal was default play signal, this processing unit was play this medium archives decoding output in regular turn according to this default playlist.
The memory storage of described play medium further includes a D/A switch unit and at least one audio output unit, is used for the sound signal of this processing unit output is converted to simulating signal and outputs to this audio output unit; One serial communication interface is used for memory storage and is electrically connected with the external data disposal system, and DCU data control unit is controlled this external data disposal system to data write and calculation process in this storage unit; One Power Management Unit and a rechargeable battery when being used for these a plurality of communication interface units and not being electrically connected with the external data disposal system, provide power supply to supply with this memory storage; One power control unit and Power Management Unit also can be used for obtaining power supply from communication interface when this when wherein a communication interface unit is electrically connected with the external data disposal system, and power supply are supplied with this rechargeable battery charge.
The memory storage of described play medium further includes following feature: when this memory storage by this serial communication interface when being connected with this external data disposal system, change the path of personal like's information and configuration information in this external data disposal system; With the archives and the external original path that is connected to this computing machine of configuration information of the correspondence in the common storage area, and check related setting; Carry out the generality operation; Recover to be modified in this external data disposal system the personal like's archives in path and the path of configuration information during end operation.
By above-mentioned memory storage, can also be when not being connected with data handling system by communication interface, voice data to its stored can be play according to user's hobby, effectively utilizes this memory storage, makes this memory storage obtain preferable value.
By above-mentioned memory storage, also further can when being connected with data handling system by serial communication interface, it use as mobile briefcase, and the user can use other people computing machine under the environment that the oneself is familiar with, and plays privacy functions.
