Abstract
The present invention relates to internet functional equipment with functions of a DVD player, which is used for respectively processing computer data and DVD video and audio data of a read only DVD so that the computer data and the DVD video and audio data are calculated in the CPUs of respective IA systems and a dynamic image compressing decoder in a DVD player. In addition, a driver of the dynamic image compressing decoder and a master control program of the DVD player do not need to be redesigned. Therefore, the present invention is suitable for the requirements of the market.
Description
Technical field
The present invention relates to a kind of equipment of internet usefulness, particularly a kind of equipment with internet usefulness of DVD player function.
Background technology
Along with the augmentation day by day of multimedia application scope, and the user is more and more higher to the requirement of image and audio, causes required data quantity stored also more and more many.Yet the memory capacity with present CD CD only has 650MB, at most only can play 74 minutes during playing back music.Have at least more than 90 minutes for a common film, and cause multi-disc dress CD CD to roll up.And when movie, whenever just must interrupt showing with the replacing dish to a paragraph, operation is inconvenience rather, uses so the CD CD does not apply gradually.
Therefore Dutch Philips company/Japanese Sony Corporation and company of Japanese Toshiba (Toshiba) reach an agreement, and digital versatile disc (Digital VersatileDisc has been proposed jointly in April, 1996 with other manufacturers, DVD) specification is to satisfy higher data storage capacity.Make a film of 90 minutes can be accommodated in the dish of 12 centimeters of diameters, and the required capacity of novel discs is brought up to 5GB (for 8 times of CD CD).
In addition, since the fast development of science and technology, internet purposes (Internet Appliance; IA) product generally has been used in general life products, if will add DVD player (DVD-palyer) function that is used for audiovisual shadow dish, then need to use the CD (DVD-ROM) and the dynamic image compression decoder (MPEGA/V Decoder) of read-only type, known as shown in Figure 1 the equipment of its structure with internet purposes of DVD player function with IDE interface.It mainly comprises by DVD-ROM 10, chipset 12, CPU 14 and dynamic image compression decoder 16 and being constituted.When running, by DVD-ROM data are delivered to chipset 12 earlier and deal with usefulness, and then by system data bus (BUS) 18, deliver to computer-internal CPU 14 runnings, wherein above-mentioned data include DVD A/V data and computer data, when CPU 14 receives DVD A/V data, then need again via chipset 12, send back to dynamic image compression decoder 16 again, when therefore transmitting by bus again, can increase the burden of system design and running, we also must write the driver (Device Driver) of dynamic image compression decoder 16 and write the primary control program (Navigator) of DVD player in addition, therefore must readjust total system, make that the Time To Market of equipment is unfavorable.
Summary of the invention
In view of this, the present invention is providing a kind of equipment with internet purposes of DVD player function, at the driver that need not change the dynamic image compression decoder and writing under the primary control program of DVD player, DVD A/V data and computer data under supporting respectively, separately dynamic image compression decoder and system CPU are operated.
The invention provides a kind of equipment with internet purposes of DVD player function, in order to receive the data of a DVD CD-ROM, wherein these data comprise computer data and DVD video-audio data.
Above-mentioned equipment with internet purposes of DVD player function comprises by a switch switch, one first chipset, a central processing unit, one second chipset, a microprocessor and a dynamic image compression decoder and being constituted.
Wherein, the switch switch connects the DVD CD-ROM, in order to when different pieces of information is imported, switches; One first chipset connects the switch switch, in order to the receiving computer data; Central processing unit connects first chipset and switch switch, after handling the computer data by first chipset, sends first deal with data; One second chipset connects the switch switch, in order to receive the DVD video-audio data; One microprocessor connects second chipset, after handling the DVD video-audio data by second chipset, sends second deal with data; And one the dynamic image compression decoder connect microprocessor, in order to second deal with data that receives is decoded.
Description of drawings
For above-mentioned and other purposes of the present invention, feature and advantage can be become apparent, preferred embodiment cited below particularly, and in conjunction with the accompanying drawings, be described in detail below:
The simple declaration of accompanying drawing:
Fig. 1 is known equipment with internet purposes of DVD player function; And
Fig. 2 illustrates is a kind of equipment with internet purposes of DVD player function according to a preferred embodiment of the present invention.
Embodiment
With reference to Fig. 2, it illustrates is a kind of equipment with internet purposes of DVD player function according to a preferred embodiment of the present invention.
In the drawings, we as can be seen this equipment with internet purposes of DVD player function comprise by switch switch 36, first chipset 26, central processing unit 28, second chipset 30, microprocessor 32 and dynamic image compression decoder 34 and being constituted.Wherein switch switch 36, first chipset 26, central processing unit 28 are positioned at IA system 22 inside, and second chipset 30, microprocessor 32 and dynamic image compression decoder 34 then are positioned at DVD player 24 inside.
At first, we are by coming reading of data on the DVD CD-ROM (DVD-ROM) 20, and wherein these data include computer data and DVD video-audio data.Then data are input to IA system 22 switch inside switchs 36, can switch at different pieces of information input at this switch switch 36, be that computer data is then kept IA system 22 runnings on the left side in the drawings for example when importing data, otherwise when the input data are the DVD video-audio data, then switch switch 36 switches, and is input to DVD player 24 inside.
Then, illustrate that computer data is input to the running of the IA system 22 on the left side, after switch 36 is sent computer data and operated to first chipset 26, deliver to the central processing unit 28 that connects first chipset 26 again and handle, send first deal with data at last to switch switch 36.Between the wherein above-mentioned switch 36 and first chipset 26, data transfer is two-way between first chipset 26 and the central processing unit 28.
Then, illustrate that the DVD video-audio data is input to the DVD player 24 on the right, after switching output DVD video-audio data and operate by switch 36 to second chipset 32, delivering to the microprocessor 32 that connects second chipset 30 again handles, send second deal with data at last to dynamic image compression decoder 34, after this second deal with data that receives is decoded, export video-audio signal again.
In sum, device structure with internet purposes of DVD player function of the present invention, make computer data and DVD video-audio data do to support computing at the CPU and the dynamic image compression decoder in the DVD player of separately IA system respectively, and we do not need to design the driver of dynamic image compression decoder and the primary control program of DVD player again, so can be fit to the equipment of the required internet purposes with DVD player function in market.
Though the present invention discloses as above with preferred embodiment; right its is not in order to qualification the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention; can be used for a variety of modifications and variations, so protection scope of the present invention should be with being as the criterion that the claim scope is defined.
