What does the following percentage mean when watching WebTV? The answer to this question may vary depending on the region and the network TV service. Generally speaking, when watching WebTV, the lower percentage indicated the network delay or network speed. For example, some WebTV might display a percentage when displaying a video, indicating that the video is loading. The higher the percentage, the higher the network delay, and the slower the video loading. Why was it that they could only watch it when it was more than 90%? Some WebTV services may require users to reach a certain network delay or speed threshold before they can watch videos normally. This threshold may vary from service to service or it may be set by the WebTV platform to protect the user's viewing experience. For example, some WebTV services may require a network delay of more than 90% to watch normally. This is because such a delay or speed can better ensure the smooth playback of the video. Different WebTV services may have different requirements. You should check the description of the WebTV service you are using to understand the minimum delay or speed requirements for normal viewing.
