A method for implementing a discrete frame-based scene section, the method comprising: obtaining at least one first tag for mapping a discrete frame to a scene section; for any second tag among the at least one first tag, performing polling query on to-be-processed first discrete frames respectively to determine whether there is a second discrete frame matched with the second tag in the first discrete frames; characterised in that: if there is the second discrete frame, marking the second discrete frame with the second tag corresponding to a scene section; if the execution of the polling query corresponding to the second tag is completed, storing start frame timestamp information and end frame timestamp information of the scene section, wherein the start frame timestamp information and end frame timestamp information of the scene section are stored respectively in the Begin_time and end_time attributes of the meta field of the stored scene section, the method further comprises: obtaining a search request carrying at least one tag; determining the scene section corresponding to the tag; generating a search result according to the stored start frame timestamp information and end frame timestamp information of the scene section and returns the search result. obtaining at least one first tag for mapping a discrete frame to a scene section; for any second tag among the at least one first tag, performing polling query on to-be-processed first discrete frames respectively to determine whether there is a second discrete frame matched with the second tag in the first discrete frames; characterised in that: if there is the second discrete frame, marking the second discrete frame with the second tag corresponding to a scene section; if the execution of the polling query corresponding to the second tag is completed, storing start frame timestamp information and end frame timestamp information of the scene section, wherein the start frame timestamp information and end frame timestamp information of the scene section are stored respectively in the Begin_time and end_time attributes of the meta field of the stored scene section, if there is the second discrete frame, marking the second discrete frame with the second tag corresponding to a scene section; if the execution of the polling query corresponding to the second tag is completed, storing start frame timestamp information and end frame timestamp information of the scene section, wherein the start frame timestamp information and end frame timestamp information of the scene section are stored respectively in the Begin_time and end_time attributes of the meta field of the stored scene section, the method further comprises: obtaining a search request carrying at least one tag; determining the scene section corresponding to the tag; generating a search result according to the stored start frame timestamp information and end frame timestamp information of the scene section and returns the search result. obtaining a search request carrying at least one tag; determining the scene section corresponding to the tag; generating a search result according to the stored start frame timestamp information and end frame timestamp information of the scene section and returns the search result.
