The CPU1050 of personal computer PC 4 shows that the data file that preservation destination, filename, password, the p.m.entry of input data file are used preserves information setting picture CW as shown in Figure 26.Have again, in the present embodiment,, suppose the catalogue of the regulation in the specified file server FS as the default value of each destination.In addition, suppose in the information of place of retention, to comprise and preserve destination and filename.In addition, password and p.m.entry are input transactions arbitrarily.Since p.m.entry information as after state and such in projector PJ4, be shown simultaneously with the filename of data file, so can be for example key word, p.m.entry when retrieving use.When the setting of password, for example import 5 numerals arbitrarily of 1 to 5 through keyboard 1551.

The CPU1050 of personal computer PC 4 judges whether the preservation destination is default value (step S120), being judged to be under the situation that the preservation destination is a default value (step S120:Yes), generates index file (step S130).On the other hand, be judged to be under the situation that the preservation destination is not a default value (step S120:No), destination (step S140) is preserved in the CPU1050 change, generates index file (step S130).As shown in Figure 27, index file is the file of each data that comprises preservation destination IP address D 1, catalogue D2, filename D3 and the p.m.entry D5 (during setting) of data file, is not included in the data itself that comprise in the data file.Thereby in general the file size of data file is about 10KB～several MB, and the file size of index file is about 1～2KB.In addition, in the present embodiment, suppose to constitute and preserve the destination, constitute place of retention information by these 3 data of preservation destination IP address D 1, catalogue D2 and filename D3 of data file by the preservation destination IP address D of data file 1 and these 2 data of catalogue D2.

CPU1050 is sent to data file and preserves the destination, is file server FS in the present embodiment, index file is sent in the external memory storage 1041 of projector PJ4 (step S150), finishes this handling procedure.That is, storing data files on file server FS is stored index file in the external memory storage 1041 of projector PJ4.

Secondly, with reference to Figure 22, Figure 23, Figure 28～Figure 33, explain and in projector PJ4, use externally stored index file in the storer 1041, the playback process of having carried out when broadcast has been stored in the data file on the file server FS.Figure 28 is the process flow diagram that is illustrated in the handling procedure of carrying out when using stored index file in the storer 1041 externally to play on file server FS stored data file among the projector PJ4.Figure 29 is the key diagram that is shown schematically in the telepilot 1040 that uses among the 4th embodiment.Figure 30 is the key diagram that an example of the menu screen among the projection display picture SR of projector PJ4 is shown.Figure 31 illustrates the key diagram that file among the projection display picture SR of projector PJ4 is selected an example of picture.Figure 32 is the key diagram of an example that the demonstration of the password input frame PB1 among the projection display picture SR of projector PJ4 is shown.Figure 33 is the key diagram of an example that the demonstration of the authentification failure display box PB2 among the projection display picture SR of projector PJ4 is shown.

In this handling procedure, the telepilot 1040 that sends instruction has possessed 1～5 numerical key 1041 of the function of the function key that the function that execution is assigned with is in advance arranged as shown in Figure 29.Telepilot 1040 also possesses operating rod 1402, menu call key 1403 and the execute key 1404 etc. that make on by projection and picture displayed SR cursor or pointer position on direction up and down, move usefulness.Have, before this handling procedure begins, suppose the menu call key 1403 of remote controller 1040, projection has also shown the menu screen shown in Figure 30.

The 1CPU1200 of projector PJ4 waits for the input (step S200:No) through the index picture display requirement of telepilot 1040.On the other hand; Press execute key 1404 under the state that the menu bar MB1 of " 2. index picture show " shows for counter-rotating if in the menu screen shown in Figure 30, utilizing the operation of operating rod 1402 to make, then the 1st CPU1200 file selection requirement (step S200:Yes) that has been judged to be generations (input).If file selection requirement that the 1st CPU1200 has been judged to be generation (input) then requires projection and shows the index picture (step S210) shown in Figure 31 for the 2nd CPU1300.

In the index picture, show with the form of index slip IB to be stored in filename and the p.m.entry in the information that comprises in the index file in the external memory storage 1041.The 1st CPU1200 judges whether to have determined the data file (step S220) that in the index picture, should play.1CPU1200 has been judged to be decision (input) and in the index picture shown in Figure 31, utilizing the operation of operating rod 1402 to make desirable file, be under the state that shows for counter-rotating of the index slip IB of " 2.*****.ppt... ", here if press the broadcast that execute key 1404 has just carried out counter-rotating data presented file.

If 1CPU1200 is judged to be the broadcast (step S220:Yes) that has determined data file, then require to set the input (step S230) of password.That is, the 1st CPU1200 requires the 2nd CPU1300 projection and shows the password input frame PB1 shown in Figure 32.

For password input frame PB1, through the password that constitute of the function key of telepilot 1,040 1041 inputs by 1～5 numeral.The 1st CPU1200 judges whether the password that has been transfused to meets the password (step S240) that has been set; Be judged to be under the situation that two passwords meet (step S240:Yes); From being obtained the preservation destination (file server FS) of determination data file, require the transmission (step S250) of determination data file with determining the corresponding index file of data file of broadcast.

The 1st CPU1200 waits for the acceptance (step S260:No) of determination data file; If accept determination data file (step S260:Yes) from file server FS; Then graphics controller 1210 is required the processing of drawing of decision files, begin to determine file broadcast (step S270).Through the projection and be presented at the view data of having been drawn generation in the graphics controller 1210 on screen of signal of video signal translation circuit 1310, LCD driving circuit 1330, LCD1332 and the projection optical system 1360 of projector portion 1030.

Be judged to be under password that telepilot 1040 is imported and the inconsistent situation of password that has been set (step S240:No) at the 1st CPU1200; The 2nd CPU1300 is required projection and shows the authentification failure display box PB2 (step S280) shown in Figure 33, do not carry out the broadcast of selecteed file.Have again,, under incongruent situation of the above password of number of times that has continued regulation, also can forbid the broadcast of determination data file for the mistake input of password.

According to present embodiment, when data file being kept at the projector PJ4, generate the index file that comprises the preservation destination information necessary in order to obtain data file through network from personal computer PC 4.And, possess the structure of the larger data file of storage file size in the less index file, the file server FS on network of in the external memory storage 1041 of projector PJ4 storage file size.In addition, the file size of index file as narrating, is about 1～KB.Thereby projector PJ4 there is no need to possess the big external memory storage of memory capacity 1041, in addition, no matter the memory capacity of external memory storage 1041 how, can transmit the larger data file of file size in fact to projector PJ4.That is,,, can construct and same execution environment when projector PJ4 transmitted data file so transmit index files through external memory storage 1041 to projector PJ4 because index file comprises the preservation destination information etc. of data file.

When in projector PJ4, playing desirable data file, projector PJ4 uses the index file of having stored to confirm the file server FS as the preservation destination of data file, obtains data file and plays from file server FS.Thereby even projector PJ4 direct storing data files in the storer 1041 externally not also can and utilize index file through storage, the situation of having stored data file with storer 1041 externally is playable data files likewise.In addition, because the file size of index file is little more a lot of than the file size of data file, can under the situation of the memory capacity of not expanding external memory storage 1041, realize and the same effect of situation of having stored the more data file in projector PJ one side.For example, even under the situation of showing, also can likewise operate projector PJ4 with the situation of in the external memory storage 1041 of projector PJ4, having stored whole data files by much human.

Moreover, through in the external memory storage 1041 of projector PJ4, storing storing data files in index file, the file server on network in advance, can under the situation that does not connect personal computer PC 4, use projector PJ4 to carry out projection separately.Thus, when using projector PJ4, can save the time that connects personal computer PC 4 at every turn.
