Read the following unedited passage and identify the INCORRECT$/$ILLOGICAL statements from the alternatives below.

To guarantee quality of service for $360$ virtual reality $($VR$)$ streaming service, the resolution of video should be high and the switching latency $($time taken from the streaming server to rendering moment at the end user's display device$)$ should be as lowest as possible. $360$ VR streaming service with nontiled video does not have any problem, but it is necessary to use tiled streaming because supporting a good quality of $360$ VR streaming service with over $8$K resolution still has realistic issues. However, in tiled streaming, it is impossible to avoid switching latency except if the tiles corresponding to the changed Viewport is already stored in the buffer. In the result of our proposed method confirms that providing low switching latency less than $450$ milliseconds when the viewport is changed, with $16$K $360$ VR video streaming service

If tiled streaming is used, tiles that are not already stored in the buffer can be streamed without any switching latency.

Quality of service is ensured by high video resolution and low switching latency.

The use of nontiled video results in implementation issues in $360$ VR streaming of videos with a resolution higher than $8$K$.$

$$ The proposed method is able to stream $16$K $360$ VR video and transmit low switching latency in less than $450$ ms$.$
