1. A display apparatus, comprising:
a display configured to display an image from a broadcast system or network and/or a user interface;
a modem;
a communication device configured to communicate with an external device;
a user input interface configured to receive an input signal; and
at least one processor in connection with the display, the modem, the communication device and the user input interface and configured to execute instructions to cause the display apparatus to:
detect a signal source of the display apparatus when the display apparatus is powered on; based on that the signal source is a first channel, determine whether a code stream exists in the first channel;
based on that a code stream exists in the first channel, parse the code stream to obtain first time information, wherein the first time information comprises first time zone information, a first Universal Time Coordinated (UTC) time and a first daylight saving time, or the first time information comprises first time zone information and a first UTC time; wherein the first channel is a Digital Television (DTV) channel;
based on that the first time information comprises the first time zone information, the first UTC time and the first daylight saving time, determine a first offset time corresponding to the first time zone information, and sum the first offset time, the first UTC time and the first daylight saving time, to obtain a current time;
based on that the first time information comprises the first time zone information and the first UTC time, determine a first offset time corresponding to the first time zone information, and sum the first offset time and the first UTC time, to obtain a current time;
in response to receiving a first command for displaying a first user interface, detect the signal source of the display apparatus, wherein the first user interface comprises a time zone setting control and at least one parameter setting control;
control the first time zone Information to be displayed at a position corresponding to the time zone setting control, and set the time zone setting control to be in a first display state and the parameter setting control to be in a second display state, to distinguish the time zone setting control and the parameter setting control via the first display state and the second display state;
wherein the time zone setting control is located between two parameter setting controls;
in response to receiving a fourth command for moving a focus in a direction from a parameter setting control at one side of the time zone setting control to the time zone setting control, control the focus to move directly to a parameter setting control at the other side of the time zone setting control;
wherein the at least one processor is further configured to execute instructions to cause the display apparatus to:
in response to receiving a fifth command for selecting the time zone setting control, not perform an operation of selecting the time zone setting control;
based on that the signal source Is not the first channel, obtain second time zone information, wherein the second time zone information is locally stored time zone information; and
control the second time zone information to be displayed at the position corresponding to the time zone setting control, and set the time zone setting control to be in the second display state;
based on that no code stream exists in the first channel, obtain second time zone information; and
control the second time zone information to be displayed at the position corresponding to the time zone setting control, and set the time zone setting control to be in the second display state.
