Based on the location of users, users were divided to two classifications named primary users (when users near to VLC-AP) and secondary users (when users far from the VLC-AP). A handover in a VLC system was proposed based on the joint transmission in which the mobile user served by two VLC-APs when moved toward the edge of the cell. In these two algorithms, a user that was in the overlapping area of two VLC-APs, was served by two VLC-APs and these two VLC-APs used different frequencies. Two algorithms were proposed to manage the soft handover in the orthogonal frequency division multiple access (OFDMA) VLC system. The coverage area of VLC-APs was dynamically altered to obtain the handover during the mobility of the user. To decrease the delay of the handover, predictive and pre-scanning received signal strength was proposed in. Based on the intensity of the received signal, a handover was investigated in two indoor VLC cases: overlapping and non-overlapping cases. To manage the mobility in VLC systems, many methods have been used. Consequently, proper indoor handover mechanism is needed between VLC-APs. Therefore, managing the mobility of the user (changing from the serving VLC-AP to a candidate VLC-AP) in VLC systems is one of the main challenges that needs to be handled. In addition, distance between VLC-APs and the optical receiver has a great impact on the performance of VLC systems. Therefore, to get full coverage, multiple VLC-APs are needed to maintain lighting and wireless connections in the whole area of the indoor environments. The coverage area of each light unit is small and one LED light unit (access point, AP) is not enough for lighting and for data communication in indoor environments such as homes and offices. In visible light communication (VLC) systems, light units are used for both illumination and data communication.

It would have been cool to have a background audio while the picture slideshow was in action. We can’t use audio effects on it for obvious reasons. That means, we can apply video effects like rotating, adjusting image contrast and brightness and overlaying text or logos. So, modify that frame with all the customization options that are present in VLC. If you think about it, an image is a single frame of a video. What Else Can We do After Opening Photos?Īfter opening photos inside VLC Media Player, we can do a lot of things that we do to videos. Now, all the photos in your VLC’s slideshow will display for the new defined number of seconds. Change the value of Duration in seconds from 10.00 to something else (like 3).Navigate to Input / Codecs > Demuxers > Image.Click on All to reveal Advanced Preferences.It can be done from the advanced settings. The pause, play, next and previous buttons can help in navigating the images.īut what if you wanted to change this 10-second limit to 3 seconds or 20 seconds. If multiple photos are chosen, then one photo will have 10 seconds and the next one will come on the screen. When a photo is opened, it displays on the screen for 10 seconds. You can select and open them like you would open any other media file. Then from the dropdown on the right, instead of Media Files (*.3g2, *.3gp …) option, choose the one that says All Files (*).Īfter that, all the files including. Just browse to the folder containing all the photos that you want to open after hitting Media > Open File. jpg files instead of the usuals.Īdditionally, the Media > Open File method can also be used to open photos inside your computer. That means selecting the individual JPG files. We will have to manually select the images inside the folder and drop it on the playlist. You can either drag a single photograph or multiple images directly to VLC’s interface or to the playlist window.īut note that folders having a collection of photos inside them cannot be dragged to the player. The drag and drop method is the best way to use it. So, how do you properly use this feature? It is just like creating a playlist for music but instead with photos. Once it reaches the end, it might loop or not loop from the start depending on what setting you have. The next one will load, and the slideshow will continue. One image will be given 10 seconds of screen time. If you drag and drop multiple photos, it will display all of them as a slideshow. Now, this functionality isn’t limited to a single image. That’s right! Drag any JPG image on to VLC Media Player and see how it will gleefully open right inside the application. It may or may not come as a big surprise, but VLC Media Player can open images as well.
