Embodiment 1

[0024] Such as figure 1 As shown in FIG. 1 , it is a processing flowchart of a method for realizing a digital photo frame by a set-top box in this embodiment. The method comprises the steps of:

[0025] S10: Detect whether an external storage device is connected to the set-top box. In this embodiment, the set-top box has a USB interface, and the external storage device can be a U disk, a hard disk connected by USB, or an SD card, wherein the SD card can be connected to the set-top box after being converted by a USB adapter. If it is not detected that the external storage device is connected to the set-top box, no action is taken; if it is detected that the external storage device is connected to the set-top box, then go to step S20.

[0026] S20: Retrieve all the files in the above-mentioned storage device, and list the picture file table. Generally, the search is performed according to the image format, and the mainstream image formats include JPG, GIF, BMP, etc. The pict...

Embodiment 2

[0031] In the above embodiment, if the resolution of the picture file is not greater than the resolution output by the set-top box, then the picture file can be read and decoded for display. If the resolution of the picture file is greater than the resolution output by the set-top box, when the picture file is read and decoded for display, the picture will be truncated by the TV screen and cannot be displayed completely.

[0032] In this embodiment, before the picture file is played on the TV according to the playing list, the picture file is further scaled. The general steps of the scaling process are to read a picture file, then decode it, resample the decoded picture according to a predetermined resolution, and output a picture with a predetermined resolution.

Embodiment 3

[0034] When playing pictures, you can also play background music. In this embodiment, on the basis of Embodiment 1, a list of music files can also be listed. According to the needs of the user, the music files supported by the set-top box are stored in the storage device in advance. In the above step S20, when the storage device is retrieved, the music files are identified according to the file format, and then a list of music files is listed.

[0035] At the same time, users can select music files to be played according to their own preferences, and the set-top box organizes and manages the music files to generate a music playback directory. In this way, music can be played while playing picture files.

Abstract

The present invention provides a method for realizing a digital photo frame by using a STB (Set Top Box), belonging to the STB field. The method comprises the steps as follows: whether an external storage device is accessed in the STB is detected; if no external storage device is detected to be accessed in the STB, no operation is adopted; if the external storage device is detected to be accessed in the STB, all files in the storage device are searched, and a picture file list is listed; then a picture playlist is generated according to picture files selected by a user; and the picture files are played in the television according to the picture playlist. In addition, the present invention also provides a STB provided with a function of the digital photo frame. According to the method and the STB in the present invention, the picture files in a user storage device are read by the STB, then the picture files can be played with the television, so that the function of the digital photo frame can be realized without buying a specialized digital photo frame device, thereby reducing user cost, and being convenient for popularization.

Description

【Technical field】 [0001] The invention relates to a set-top box, in particular to a method for realizing a digital photo frame by the set-top box and the set-top box. 【Background technique】 [0002] With the gradual popularization of digital cameras, digital photos are increasing day by day. In addition to the computer, the general family needs to use a digital photo frame to play photos. However, at present, the digital photo frame is a special device for displaying digital photos, and the cost is relatively high, and the screen is small, and the user needs to purchase it separately. 【Content of invention】 [0003] Aiming at the problems of high cost and inconvenient popularization of digital photo frames, a method for realizing digital photo frames by a set-top box is provided. [0004] A method for a set-top box to realize a digital photo frame, comprising the following steps: detecting whether an external storage device is connected to the set-top box; if no external...
