You need to have a DLNA server and a DLNA client to transmit content using this standard ,  You can play any multimedia file stored on the DLNA server using the DLNA client because of the wireless communication of your Wi-Fi or an Ethernet connection .

You know that DLNA is based on a widely used Universal Plug and Play (UPnP) platform for digital media management , file discovery and control , UPnP defines the types of devices that DLNA supports & the methods for accessing the media over the network , If you have the router in your home , you will be able to link DLNA-compliant products across your home network , If your router is wireless ,  You can do it all over Wi-Fi too .

Video streaming websites have been around for a long time ,  They are very popular , The people like streaming video websites because the website server has to host the large video file while the user can access it with the smartphone or the tablet , Most mobile computing devices do not have the storage space to accommodate the video library and that is why the websites are convenient .

DLNA disadvantages

One of the drawbacks that you may run into when sharing the content between your household devices is the copyright restriction , The Digital Rights Management (DRM) is another stumbling block , DRM controls the way that the people can share the digital media to protect copyright .

Some devices , despite being DLNA-certified , won’t share certain music or video files with the other devices due to DRM restrictions in place , If you’re a big user of Apple or Samsung products , you may be better served with their proprietary systems rather than DLNA if you want to share media files .

However almost 250 manufacturers are part of the DLNA Alliance , Some brands offer their own take on home networking , while the others don’t support DLNA at all , The file formats can be a bit of an issue , Some DLNA devices may play MP4 video files or the popular DivX , but the device is being sent to be unable to recognize this particular file type .

Some devices come with incompatibility but some multimedia servers like TVersity can solve this problem by encoding content on the fly , But this can be problematic to set up with such advanced settings .
