Provided is a method for creating a virtual reality content, storing the virtual reality content in a transmission buffer, and after that, managing the transmission buffer. A server creates the virtual reality content based on user's motion information, stores the virtual reality content in the transmission buffer and is allowed to modify the virtual reality content stored in the transmission buffer based on subsequently received user's motion information, so that the most recent user's motion information can be appropriately reflected in the virtual reality content. It is possible to provide a more immersive virtual reality service.

The present invention relates to a method for estimating an optimized transmission bit rate in a wireless local area network (LAN) system, which is to provide an accurate data transmission bit rate according to channel status when block data are transmitted in the wireless LAN system. According to the present invention, there is provided a method for estimating an optimized transmission bit rate according to the status of a data transmission bit rate in a wireless LAN system, comprising the steps of determining whether to change a current data transmission bit rate in a wireless LAN network; and estimating an optimized transmission bit rate on the basis of results of the determination in the determining step, and reflecting the estimated transmission bit rate upon transmission of data. The method is effective in that when data blocks are transmitted in the wireless LAN system, the performance degradation of data transmission invited due to an inappropriate selection of a transmission bit rate can be reduced.
