A mobile multimedia information storage and play device includes a control module, an information transmission port, and an information memory. Said control module has a central memory, an interface controller and an output port controller connected with the central processor. Said information transmission port includes multiple kinds of ports, having the character of good mobility, large volume and integrated memory and play. The storage and play method includes: The central processor initializes the system, detects the ports, reads the program code in the program memory in the random memory. The control module fetches information in the information memory to decode then plays the processed data via the output port controller.
Description
Technical field
The utility model belongs to multimedia technology field, belongs to multimedia information storage play-back technology field especially.
Background technology
Existing recording (as) band, CD (comprising VCD, DVD CD etc.) is simple multimedia messages carrier, need to use corresponding playing device just can read its contained information, and pass through the content of sound equipment, televisor or other device multimedia rendering information; And for recording (as) machine, CD player (VCD, DVD player etc.), have only that information reads, conversion and transmitting function, can not store the multimedia messages content, general machine does not have directly to show the function of multimedia messages yet.At present along with the popularizing and the raising of transfer rate of internet, the multimedia messages resource on the network is more and more abundanter, existing recording (as) machine, CD player etc. can't directly use the multimedia messages resource on these networks.
A kind of portable CD player is also arranged at present, have small-sized LCD, can under mobile status, play the content of VCD or DVD CD, also still can only use CD as information carrier.
Existing in addition CD, even the bigger DVD CD of capacity, information capacity also has only tens000000 (G) bit, reproduction time is generally in two hours.And abundant multimedia information content more and more requires storage space to be the bigger the better.
Summary of the invention
The objective of the invention is to overcome the information stores and the playing device that have multimedia technology now is separated, defective such as poor mobility, off-capacity, and a kind of portable multimedia information storage playing device and method are proposed, can in device, store the multimedia messages of larger capacity, can utilize internal or external screen to show simultaneously and think highly of the existing information content.Have that movability is good, capacity is big, incorporate characteristics are play in storage.
Purpose of the present invention can reach by taking following technical measures:
Design, make a kind of portable multimedia information storage playing device, comprise casing, control module 1, the information transmission port 2 and the power supply that are connected with control module; Also comprise the information-storing device 3 that is connected to described control module 1; Described control module 1 is provided with central processing unit 11, and the program storage 12 that is connected with central processing unit 11 respectively, random access memory 13, interface controller and output port controller; Described information transmission port 2 comprises USB port.
A kind of multimedia information storage player method, this method comprises the following step:
11 pairs of systems of central processing unit carry out initialization, detect the situation of each port;
Program code in the program storage 12 is read in the random access memory 13;
Control module 1 checks by interface controller whether transmit port etc. has the signal input, just carries out message exchange if having, and waits down the operational order that goes on foot; If there is not the signal input, just directly reads the information in the information-storing device 3 and wait down the operational order in step;
To the multimedia messages that reads from information-storing device 3, central processing unit is decoded, and again the data of handling is play output by the output port controller.
Description of drawings
Fig. 1 is the portable multimedia information storage playing device of a present invention principle schematic;
Fig. 2 is a workflow synoptic diagram of the present invention;
Embodiment
Below in conjunction with accompanying drawing in detail embodiments of the invention are described in detail.
A kind of portable multimedia information storage playing device comprises casing, control module 1, the information transmission port 2 that is connected with control module and power supply 6; It is characterized in that: also comprise the information-storing device 3 that is connected to described control module 1; Described control module 1 is provided with central processing unit 11, and the program storage 12 that is connected with central processing unit 11 respectively, random access memory 13, interface controller and output port controller; Described information transmission port 2 comprises USB port.
Use button or telepilot 41 to open the power supply of apparatus of the present invention, 11 pairs of systems of central processing unit carry out initialization, detect the situation of each port; Program code in the program storage 12 is read in the random access memory 13, and random access memory 13 is SDROM, DDR-SDROM, RDROM or other novel memory chips.Control module 1 checks by interface controller whether USB port, hard-disk interface (as IDE, PATA or novel serial hard disk interface SATA), 1394 ports, OTG port etc. have the signal input then, just carry out message exchange if having, wait into the operational order in step down; If there is not the signal input, just directly reads the information in the information-storing device 3 and wait down the operational order in step.
Described information-storing device 3 is at least a kind of in FLASH chip, CF card and the HDD hard disk, under prior art, these storeies all had a considerable capacity, special hard disk tens even hundreds of million capacity enough load the abundant multimedia information content.
To from information-storing device 3 or the multimedia messages that directly comes from the information transmission port reads, central processing unit is decoded, again the data of handling are play by the output port controller and outputed to delivery outlets such as being connected to sound, video, broadcast by external tv equipment or other equipment; Perhaps directly be sent to built-in display 5 broadcast contents by the output port controller.
Described information transmission port 2 also comprises a kind of port in hard-disk interface, OTG port, 1394 ports at least, and abundant external-connected port makes apparatus of the present invention obtain the multimedia messages resource more easily.Wherein use the OTG port more can between two identical devices, carry out information copy or exchange.
In other embodiment, the multimedia information storage playing device can also comprise the display 5 that is connected with described output port controller, does not need external display just can play like this, uses more convenient.
Described program storage 12 is to repeat to write nonvolatile memory E2ROM, employing can repeat to write nonvolatile memory, make apparatus of the present invention have good upgrading ability, adapt to the renewal upgrading of working routine, also make apparatus of the present invention that new multimedia messages is had higher compatibility.
Power supply 6 promptly can use internal battery, also can use outside constant voltage dc source to power; When not having external power source, internal battery is worked automatically; When external power source was arranged, external power source charged to internal battery in to the device power supply.
