Abstract: A video sharing method and system in smart TV, the method comprising: in the process of playing a video by a smart TV, receiving a control instruction to intercept the currently playing video, the control instruction comprising an intercept start instruction and an intercept end instruction to intercept the currently playing video; according to the playback progress of the current video upon receipt of the intercept start instruction and the intercept end instruction, acquiring the start time and the end time of the intercepted video clip in the current video; uploading the identification information of the current video and the start time and the end time to a server, such that the server generates a shared link about the intercepted video clip, and provides the shared link for a user. The present method can share the link of any highlight in a video program played on a smart TV, thus improving the convenience and flexibility of video sharing in the smart TV.

Abstract: A method includes: when a login request is received from a user, sending account information input by the user to a user center server of a smart TV for authentication; after the authentication succeeds and login is completed, receiving login information returned by the user center server and corresponding to the account information, and saving the login information in a preset database; and when the user enables a target application in the smart TV, receiving a login status query request sent by the target application, returning a response message to the target application, and notifying the target application that the current user has logged in, so that the target application acquires corresponding login information from the preset database, and completes a service request by using the login information. With the present disclosure, uniform account management on various applications in a smart TV can be achieved, thereby saving resources.

Abstract: A cursor control method and cursor control device of a smart TV, wherein when a character inputting box in a character inputting interface is in a non-editing state, the method includes the following steps: receiving and resolving a control signal from a remote control; triggering the character inputting box into an editable state if the control signal instructs to move the cursor into the character inputting box; judging whether a string exists in the character inputting box; if the judgement result is yes, judging a target position in the string where an input error may exist; and positioning the cursor at the target position in the string. The cursor control method and cursor control device of a smart TV in the present disclosure can make modification of strings existed in the character inputting box is more convenient, thereby improving modification efficiency and saving input operation cost for users.
