before receiving the first instruction, receive a fourth instruction for moving the selector to a video application icon via the user input user interface from the user by operating a first key on a remote control of the display apparatus; and

in response to the fourth instruction, move the selector to the video application icon and output a fifth voice content corresponding to the video application, wherein the fifth voice content comprises a name of the video application.

6. The display apparatus according to claim 5 , wherein the fifth voice content further comprises an alert voice for indicating existence of a first explanation voice for the video application following the fifth voice content.

7. The display apparatus according to claim 6 , wherein the controller is further configured to:

while the selector is holding on the video application icon, receive a fifth instruction via the user input interface by operating a second key on the remote control; and

in response to the fifth instruction, output the first explanation voice for the video application without activating the video application icon, wherein the first explanation voice comprises content or controls in a user interface after activating the video application icon.

8. The display apparatus according to claim 7 , wherein the first explanation voice comprises another alert voice for indicating a second explanation voice for the video application following the first explanation voice.

9. The display apparatus according to claim 8 , wherein the controller is further configured to:

while the selector is holding on the video application icon, receive a sixth instruction via the user input interface by operating the second key on the remote control; and

in response to the sixth instruction, output the second explanation voice for the video application without activating the video application icon, wherein the second explanation voice comprises content different from the first explanation voice.

10. A content-based voice output method, comprising:

in response to a first instruction via a user input interface of a display from a user, locating a selector on a time progress bar of a video on a user interface of the display and outputting a first voice content corresponding to a first progress point indicated by the selector on the time progress bar in real time; wherein the user interface comprises at least one item, and the selector is configured to indicate that an item on the user interface is selected and move to select different items based on user inputs;

after outputting the first voice content corresponding to the first progress point, determining whether a voice content corresponding to a next progress point needs to be output, by performing:

in response to a second instruction, via the user input interface from the user corresponding to a second progress point on the time progress bar, determine to output a second voice content corresponding to the second progress point indicated by the selector on the time progress bar based on determination that playing of the first voice content corresponding to the first progress point has been completed, and

in response to a third instruction, via the user input interface from the user corresponding to a third progress point on the time progress bar, determine not to output a third voice content corresponding to the third progress point indicated by the selector on the time progress bar based on determination that either the playing of the first voice content corresponding to the first progress point has not been completed or a preset time interval since the playing of the first voice content has not reached,

wherein the third progress point is between the first progress point and the second progress point on the time progress bar and the preset time interval is set by the user.

11. The content-based voice output method according to claim 10 , wherein play time on the time progress bar is updated in real time, and the selector on the time progress bar is configured to move with a current play time on the time progress bar.

12. The content-based voice output method according to claim 10 , further comprising:

upon receiving the first instruction, determining a state of the video, wherein the state of the video playing comprises playing and paused;

in response to the state of the video playing being the paused state and the first instruction, outputting the first voice content corresponding to the first progress point indicated by the selector on the time progress bar directly without adjusting sound volume of the video; and

in response to the state of the video playing being the playing state and the first instruction, outputting the first voice content corresponding to the first progress point indicated by the selector on the time progress bar with a volume higher than a volume of the video.

13. The content-based voice output method according to claim 12 , further comprising:

after outputting the first voice content with the volume higher than the volume of the video, restoring the volume of the video to a volume of the video before outputting the first voice content.

14. The content-based voice output method according to claim 10 , further comprising:

before receiving the first instruction, receiving a fourth instruction for moving the selector to a video application icon via the user input user interface from the user by operating a first key on a remote control of the display apparatus; and

in response to the fourth instruction, moving the selector to the video application icon and output a fifth voice content corresponding to the video application, wherein the fifth voice content comprises a name of the video application.

15. The content-based voice output method according to claim 14 , wherein the fifth voice content further comprises an alert voice for indicating existence of a first explanation voice for the video application following the fifth voice content.

16. The content-based voice output method according to claim 15 , further comprising:
