1. A display apparatus, comprising:
a display;
a user input interface, configured to receive an instruction from a user; and
a controller, in communication with the display and the user input interface and configured to perform:
while a program content of a first channel in a first channel list is played on the display, in response to a digit of a channel number input from the user via a remote control device, presenting the channel number on an electronic program guide (EPG) interface on the display in real time, and presenting a selector for indicating a current channel on the first channel on the EPG interface, wherein the first channel list comprises a plurality of channels from a type of broadcasting signal, and the channel number comprises one or more digits input one-by-one via the remote control device; and
in response to a length of the current channel number after receiving the digit of the channel number input from the user being equal to a maximum length of the channel number in the first channel list within a first preset duration, switching the program content of the first channel to a program content of a second channel corresponding to the current channel number without a user's confirmation instruction via a button on the remote control device within the first preset duration, landing the selector on the second channel corresponding to the current channel number, and not responding to a digit of a channel number that the user continues to input within the first preset duration;
in response to a length of the current channel number after receiving the digit of the channel number input from the user being less than a maximum length of the channel number in the first channel list, updating the current channel number presented on the display in real time;
in response to a length of the current channel number after receiving the digit of the channel number input from the user being greater than a maximum length of the channel number in the first channel list, not responding to the digit recently received from the remote control device by not presenting the digit recently received from the remote control device on the display.
