Problems solved by technology

But when using the standard DLNA protocol to browse multimedia files at present, due to the transmission process, when the user selects a picture file to be browsed, the picture file is first compressed, and then the compressed picture file is transmitted to the wireless device that plays the picture file. equipment, so the loading speed of picture files is slow, which leads to slow browsing speed of pictures, and in severe cases, it will cause memory overflow and other problems

no. 1 example

[0065] refer to image 3 , image 3 It is a schematic flowchart of an embodiment of the server compressing pictures in the picture browsing method for sharing files of the present invention. Based on the first embodiment, in this embodiment, the step of compressing pictures by the server specifically includes:

[0066] Step S301, proportionally scaling the size of the picture, and generating a scaled compressed picture;

[0067] Step S302, saving the compressed picture.

[0068] In this embodiment, the server acquires the height and width of the picture, calculates a scaling value, and compresses the picture proportionally according to the scaling value to generate a scaled compressed picture. For example, the height and width of the original picture are 3000 and 4000 pixels respectively. If the height and width are both reduced by 10 times, the scaling values ​​of the height and width of the picture are 300 and 400 pixels respectively, and finally wait according to the sca...

[0078] refer to Figure 5 , Figure 5 It is a schematic flowchart of another embodiment of the server compressing pictures in the picture browsing method for sharing files of the present invention. Based on the fourth embodiment, in this embodiment, after performing the step S301, it also includes:

[0079] Step S310, naming the compressed picture with the absolute path of the picture.

[0080] In this embodiment, since the compressed picture is named with the absolute path of the picture, it is prevented that when the pictures located in different paths have the same name, the compressed picture has the same name, and the user cannot view the picture normally. .

[0081] The present invention also provides a picture browsing system for sharing files, which is used to realize the above method. refer to Figure 6 and Figure 7 , Figure 6 It is a schematic structural diagram of an embodiment of the picture browsing system for sharing files in the present invention; Fig...

no. 3 example

[0099] Based on the third embodiment, in this embodiment, the server 10 further includes a second processing module 104, and the judging module 101 is also used to judge whether there is an SD card in the server 10;

[0100] When there is an SD card in the server 10, the judging module 101 is also used to judge whether there is a folder for storing compressed pictures under the root directory of the SD card, and if it exists, the compression flag is set to be true by the second processing module 104 . If there is no folder for storing compressed pictures under the root directory of the SD card, then a folder for storing compressed pictures is created in the SD card by the second processing module 104, if the folder is created successfully, then the compression flag is set as true ; If the creation of the folder fails, set the compression flag to a false value and end the compression operation.

[0101] When there is no SD card in the server 10, the judging module 101 is also ...

Abstract

The invention discloses a method and system for browsing pictures of a shared file. The method for browsing the pictures of the shared file comprises the following steps that a server judges whether a target picture is compressed or not; if the target picture is compressed, the server sends URL information of the compressed picture of the target picture to a player terminal; if the target picture is not compressed, the server compresses the target picture and sends URL information of the compressed picture of the target picture to the player terminal; when a next pre-browsed picture is not compressed, the server compresses the next pre-browsed picture; the player terminal outputs an HTTP request to the server according to the URL information; the server receives the HTTP request and sends the data of the compressed picture to the player terminal according to the HTTP request, and then the player terminal displays the compressed picture. The method and system for browsing the pictures of the shared file improve the speed for browsing the shared pictures.

Description

technical field [0001] The invention relates to the field of multimedia applications, in particular to a method and system for browsing pictures of shared files. Background technique [0002] With the development of wireless transmission technology, wireless local area networks (such as home LAN and office LAN) have gradually become popular in people's daily life, and more and more wireless devices appear in a wireless local area network. Realizing seamless sharing of data resources between wireless devices within a distance can bring great convenience to users. But when using the standard DLNA protocol to browse multimedia files at present, due to the transmission process, when the user selects a picture file to be browsed, the picture file is first compressed, and then the compressed picture file is transmitted to the wireless device that plays the picture file. device, so the loading speed of the picture file is slow, which leads to the slow speed of browsing pictures, a...
