2. catalogue Business Process Analysis:

The catalogue and the arrangement of the data that is of working greatly in the operation system of the present invention, because catalogue work is mainly carried out by hand by the catalogue personnel, when making a catalogue level more for a long time, catalogue efficient is lower.According to demand 400 hours/day data production requirement of proposition at present, the catalogue production line of a multi-node collaborative job of planning, each node of this catalogue production line can be adjusted to adapt to the catalogue needs of dissimilar programs by the operational management configuration.By catalogue operational management workstation cataloging syytem is carried out operational management and statistical study simultaneously.

Be the design of example explanation catalogue flow process below with the news category program, this catalogue flow process is just illustrated at the catalogue flow process of news category program, in actual cataloged procedure, can carry out the adjustment of flow process and link at any time, so that improve catalogue production efficiency according to the condition of production.

Scheme one: too many levels serial catalogue flow process, see Figure 19, among the figure: the index of 19.1.1 program layer, 19.1.2 program index audit, 19.1.3 fragment clauses and subclauses are set up and the slice layer index, 19.1.4 fragment index audit, 19.1.5 the camera lens clauses and subclauses are set up and the index of camera lens layer, 19.1.6 camera lens index audit, 19.1.7CKM handles, and 19.1.8CKM manually proofreads, examine 19.1.9 catalogue is total, 19.1.10 catalogue finishes, 19.2 elementary catalogue metadata informations, and 19.3 extract key frame information automatically, 19.4 low code stream video/audio, the metadata information 19.5 finally make a catalogue, 19.6 final key frame pictures, 19.7 cataloging syytem operational managements.

According to demand and meet following catalogue standard, to its column of program of news category elementary cell as the program catalogue, promptly according to program in the catalogue standard, fragment, scene, the division of camera lens, the news column is as the program layer, news item is as slice layer, and the scene index does not need, and needs index to arrive concrete news camera lens for highlight.Therefore, in above-mentioned workflow, whole cataloged procedure is divided into: the index of program layer, the audit of program layer, fragment definition and index, the fragment audit, camera lens definition and index, the camera lens audit, CKM handles, and always examines this several catalogue links.

The index of program layer:

For the news category program, its catalogue elementary cell is decided to be the news column, and for example: index programme information on this aspect of news hookup comprises: name of tv column, just to inscribe one's name, and the column phase is inferior, age, broadcast time, information responsible etc.Also comprise some technical parameters in addition, as: channel format, colour/black and white, picture the ratio of width to height, image quality, sound quality, bearer type, standard, video data code check, video sampling form, video code model, file layout etc.

The information spinner of this aspect will be gathered from pre-service, and the metadata information that front end production links such as transcoding just exist (for some technical parameters, mainly come from and gather and the transcoding link) also can be imported by hand by the catalogue personnel.

The program audit:

Need just can enter next catalogue link through audit to the metadata of finishing after the program index, groundwork one in the audit is to judge whether inventory information is correct, the 2nd, judge whether to carry out the catalogue of next level, if need then transmission task to fragment index node; CKM handles and the total audit of catalogue if do not need then directly to carry out.

Fragment definition and index:

For the news category program, fragment means each news item.The definition index of fragment comprises by browsing video/audio gets the location ready, identify an independently news footage, and to its index of making a catalogue accordingly, here mainly be based on the index of content, and the notes that do not relate to technological layer are recorded, as: just inscribeing one's name, data provides, information responsible, synopsis (mouth is broadcast original text) etc.The index of slice layer also comprises arrangement and the modification to contained key frame information in each fragment in addition.

The fragment audit:

Automatically carry out segment after the fragment index is finished and examine, similar with the program audit, except that carrying out the inventory information audit, also need to analyze and judge whether to carry out lower floor and make a catalogue, root division border situation transmission task factually arrives camera lens index link or CKM and total link of examining.

Camera lens definition and index:

For some valuable news, some camera lens wherein need carry out independent index so that later-stage utilization.The index and the segment of camera lens are similar, need get the location ready by browsing audiovisual information, and create shot record.Though it is the indexing content of camera lens is less, professional very strong.

The camera lens audit:

Automatically enter camera lens audit node after the camera lens index is finished, carry out camera lens index information check, check by after enter CKM processing links and total examining automatically.

CKM handles:

The CKM software package of TRS can be classified automatically to Chinese written historical materials, abstract extraction, and the auxiliary automatically indexing work of computing machines such as cluster, but because its Word message of video and audio material is limited, so the CKM treatment effect needs checking.In the native system scheme, adopt 1 CKM server to carry out automatic cluster and abstract extraction work, and set 2 workstations the result is verified.

Catalogue is total to be examined:

After above-mentioned task is all finished, enter the total link of examining of catalogue.Catalogue is total to be examined whole tree-shaped programme information (program, fragment, fragment, scene, camera lens) is carried out complete audit and browses, in case examine by total, then data become final catalogue metadata, otherwise return corresponding processing links.

According to top flow scheme design as can be seen, whole catalogue flow process mainly adopts too many levels work in series mode, and its great advantage is the flow process compactness, division of labor careful, and dissimilar personnel can be engaged in different catalogue work respectively.In addition, the infiltration of audit link is set up successive check in the catalogue flow process.

Scheme two: too many levels serial parallel catalogue flow process, see Figure 20, among the figure: the material record of 20.1 all uncatalogs, 20.2 program predeterminations justice and look audio parsing, 20.3 program layer catalogue, 20.4 slice layer definition and first catalogue, 20.5 camera lens layers catalogue, 20.6 slice layer depth indexings and key frame audit, 20.7 camera lens layer depth index, 20.8CKM handle, 20.9 catalogues are total to be examined, 20.10 final catalogue metadata.

By this process design plan as can be seen, at the program in the scheme one, fragment, the catalogue of three aspects of camera lens adopts parallel mode to carry out, and can improve catalogue efficient greatly like this.In the catalogue of certain aspect, the work in series mode that can adopt many people to coordinate to make a catalogue too.

In sum: the design of catalogue flow process must be carried out dynamic-configuration by workflow management, adjusts flexibly and assembly according to different program categories and catalogue requirements of one's work.80 catalogue workstations have been disposed in the system schema and 10 catalogue examination stations need form the catalogue production line of the complete science efficiently of a cover through the configuration of workflow management.
