In a specific embodiment, the terminal starts a navigation application, receives an origin and a destination set by a user, and approximately estimates a travel time from the origin to the destination by using a Global Positioning System (GPS) of the navigation application and combining the acquired road condition information. Here, the traffic information may be known from a road monitoring system.
Therefore, the terminal can conveniently judge the overall duration of the recommended multimedia information according to the travel duration, so that the duration of the multimedia information recommended to the user is adaptive to the travel duration, the problem that the user may not see or cannot see the recommended multimedia information due to the fact that the recommended multimedia information duration and the travel duration are not in time is solved, and the watching experience of the user is improved.
As another optional implementation, the acquiring the trip information of the user includes:
the travel information is formed by at least one of an origin point, a destination and a route point set in a planned travel set in a calendar application by a user, and a predicted arrival time.
In a specific embodiment, the terminal acquires a planned travel of the calendar application, determines at least one piece of geographic position information of an origin point, a destination point and a route point and at least one piece of time information of predicted arrival time, departure time and the like according to the planned travel, and roughly estimates the travel time length from the origin point to the destination point.
Therefore, the terminal can conveniently judge the overall duration of the recommended multimedia information according to the travel duration, so that the duration of the multimedia information recommended to the user is adaptive to the travel duration, the problem that the user may not see or cannot see the recommended multimedia information due to the fact that the recommended multimedia information duration and the travel duration are not in time is solved, and the watching experience of the user is improved.
In one embodiment, the terminal determines event information based on the scheduled itinerary of the calendar application, and presumably estimates the purpose of the user's itinerary or upcoming events, such as business negotiations, birthdays given to girlfriends, etc.
Therefore, the terminal can conveniently judge the type of the recommended multimedia information according to the trip event information, so that the type of the multimedia information recommended to the user is adaptive to the trip purpose, and the problem that the user is likely to have low satisfaction degree on the recommended multimedia information due to the fact that the type of the recommended multimedia information is not consistent with the current trip is solved.
For example, the calendar application has a planned travel of 12, which is flown by beijing to shanghai to give a girlfried birthday, and the terminal locates the category of the recommended multimedia information as a love comedy story or a birthday story according to the event information of giving the girlfried birthday, but does not locate the category of the recommended multimedia information as a love tragic story.
In a specific embodiment, the terminal determines time information such as departure time and arrival time according to a planned travel of calendar application, and determines holiday information related to the travel, such as love anniversary, according to the time information; or determining the throttle information related to the travel according to the time information, such as winter, winter solstice and the like.
For example, the planned itinerary for a calendar application is: if the departure time is thirty years, the terminal locates the category of the recommended multimedia information as the perennial subject matter or the comedy subject matter according to the time information of thirty years, and does not locate the category of the recommended multimedia information as the tragedy subject matter.
As another optional implementation, the obtaining the trip information of the user includes:
and running a multimedia application, and forming the travel information according to at least one of the starting point, the destination and the route point input in the multimedia application by the user.
