WiFi Direct lets you push content directly to a TV from another device (if both devices support WiFi Direct). DLNA lets you share your entire media library from a device and use it on a TV but it requires a router in-between. Now the DLNA standard and WiFi Direct standard will join forces
WiFi Direct and DLNA join forces
Today DLNA requires a router between two devices to work but the DLNA standard will soon support WiFi Direct.
Stream content directly between devices
This basically means that users can share media content directly between devices such as laptops, tablets, PC/Macs, smartphones etc. and still keep the features of the DLNA specification such as content lists. The DLNA group also says that only one of the two devices need to be WiFi Direct certified, giving you the opportunity to share content from your smartphone to your PC even though the latter does not support WiFi Direct.
A date of availability has not been disclosed but we are guessing that current users either need to update their firmware or to buy new hardware.
