Many WebTV programs could automatically play the next episode by pressing the "autoplay" button on the remote control. However, if the TV supported the smart play function, it could also use the smart play function to automatically play the next episode. The specific steps were as follows: 1. Turn on WebTV and switch to the TV series you want to watch. 2. Press the "Smart Play" button on the remote control to activate the smart play function. 3. In the smart play interface, the next episode can be automatically played according to the plot progress or time progress. It should be noted that if the TV supports the smart play function, it is recommended to turn off the TV and turn it on again to ensure that the smart play function is activated normally. In addition, if you were using a smart TV, you could also check the TV's manual for more detailed operation steps.
