Embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and by embodiment.
The main thought of technical solution of the present invention provides a kind ofly can carry out related indexing method based on incident index with the resource index of time particle to audio frequency and video, and the content that allows to index possesses extensibility, indexing rule is safeguarded, can create and safeguard many cover rules, different indexing method when providing at the different resource type for the user, to determine its data structure for the result of this indexing method simultaneously, solve the relevance on time shaft between audio and video resources itself and the external resource from data plane.
Fig. 1 is the structural representation of audio, video data indexing system in the specific embodiment of the invention.As shown in Figure 1, this indexing system comprises audio frequency and video playing module 101, index operational module 102, rule parsing module 103, regular data module 104 and data memory module 105.
Wherein, the index operational module is connected with data memory module with audio frequency and video playing module, rule parsing module respectively, and the rule parsing module is connected with the regular data module.
Audio frequency and video playing module playing audio-video data, the index operational module is determined the audio, video data indexed positions, triggering index operation, selection needs the index dimension of index, the index operation interface that shows according to the rule parsing module adds indexing content, and the index result sent to data memory module, the rule parsing module obtains the indexing rule data from the regular data module, resolve, and according to current index dimension demonstration index operation interface, regular data module stores indexing rule data, the audio frequency and video index result that data memory module storage index operational module is sent.
Fig. 2 is the process flow diagram of audio, video data index in the specific embodiment of the invention.As shown in Figure 2, this flow process may further comprise the steps:
The rule of how to carry out index that the regular data module is pre-defined, it has at first defined indexing type, and indexing type mainly is divided into two kinds, and a kind of is the resource index, with the purpose that is associated as between foundation and certain static resource, as one section text of index, a pictures or a network address; Another kind is the incident index, with set up and certain dynamic event between related index be purpose, for example exercise test, comment or ballot are mutual etc.Under these two kinds of big indexing types, at concrete subtype, then need further differentiation, regular data defines these all types.
At indexing type, the regular data module has further proposed the index dimension, and the corresponding concrete indexing type of each index dimension is as shown in table 1.
Table 1
| The index dimension | Indexing type | The indexing content example |
| Main knowledge point | Resource index/text | Six grades numbers difficult to understand |
| Affiliated subject | Resource index/text | Mathematics |
| Subclass | Resource index/text | Number difficult to understand |
| Related picture | Resource index/picture | 123.jpg |
| Associated audio | Resource index/audio frequency | Abc.mp3 |
| The encyclopaedia network address | Resource index/URL | Http://www.example.com/1.html |
| Exercise after class | Incident index/test | ? |
| Test in the class | Incident index/test | ? |
An indexing type can be at a plurality of index dimensions, and an index dimension can only be an indexing type, and these indexing types both can utilize indexing system inside to come record, also can utilize the indexing system outside to come record data.For example, at the incident index of this test of exercise after class, indexing system can be done association with an examination test system that has existed, and only need indicate that type is exam in indexing system, and concrete examination is major key 100 that.
Step 203, rule parsing module read the indexing rule data, resolve, and show the index operation interface according to current index dimension.
Regular data has only just proposed each index dimension and its corresponding indexing type, and the rule parsing module is responsible for carrying out concrete parsing and is presented, when the index operational module had been selected certain indexing type, the rule parsing module can be called corresponding analytical capabilities and carry out the interface and present.
The rule parsing module is configurable flexibly, still for example with top examination system, when an examination of mark type, the rule parsing module can be regarded as the examination system that has existed with another one to the concrete parsing of this type and do the interface butt joint, and the content screening of all examination paper is provided.
And if the resource index module of a text class, then the rule parsing module will point out a text input to fill in for the user; When being the resource index module of a video file, the rule parsing module is then pointed out the user to select a local file or is filled in an external file path.The purpose of rule parsing module is the interface that each indexing type is provided the input index, for user's complete operation.
When concrete index, the user establishes a time point or time period (when the user has only selected a time point, promptly at the index of time point), and then selects specifically to want the content of index, after index is finished, call data memory module and be translated into specific data layout.
The preservation essential record start time point and the concluding time point (also can have only a start time) of data, determine indexing content then in this time point or time period correspondence, the content of index both can be a complete content--for example local binary data of just preserving complete text, complete picture file, it also can be an external address, the url of a picture for example, the examination paper ID of an outside examination system.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with the people of this technology in the disclosed technical scope of the present invention; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
