Description
Technical field
The present invention relates to broadcast TV program production system, relate in particular to inking device and the method for service sub-system in television station production system.
Background technology
Current television station production system is based on full court planar network architecture and networking manufacturing technology, its core architecture corresponding to business in platform and each service sub-system, substantially realized the networking production and construction of standardized TV station and standard, and realized the production automation and omnidistance without paper without bandization.TV stations at different levels, according to self scale and service conditions, can realize cordwood system Construction, as shown in Figure 1 substantially.
But the television station production system of existing full court planar network architecture remains in following some shortcomings:
(1) demand that meets distributed business model is still had to limitation
TV station's system of full court planar network architecture is all business in platform due to what mainly face at the beginning of design, therefore consider not enough to the support of the outer business of platform.Such as: the private network connection technology of using between the TV station unit of several dispersions, can not effectively utilize day by day fast-developing public network resource; The resources such as storage that strange land production system comprises, calculating be all by strange land relatively independent design, therefore can not carry out unified allocation of resources and management, thereby in most of the cases, production system user can only operate local limited resource; And the data manipulation between other unit and material and program is mutual, all take indirect operation pattern as main (comprising the operations such as document retrieval, migration copy and file warehousing); Due to the unified managing portal planning of shortage, the demands such as the access to branch system, mobile system and mobile subscriber, all need planning separately and process, and therefore existing production system construction complexity is very high, and later maintenance difficulty.
(2) to meet multiple core demands simultaneously, still there is limitation
The one, the limitation that issue is supported to new media.Under commensurate's organizational system, owing to can not realizing platform net interlock (being to produce resource-sharing and the broadcast of synchronizeing between network and the Internet in TV station), can not utilize fast existing resource seamlessly to support new media system, thereby can not efficiently the video and audio content-data in new media system be drawn back to constitution equipment and personnel's waste thus.And under commensurate's organizational system not, the efficiency that video and audio content externally provides is lower, need the long period to carry out secondary format conversion and content delivery exchange, form thus the wasting of resources.
The 2nd, to the limitation of content collecting and distribution support.Video and audio content aggregation is mainly included based on digital serial interface (SDI, Serial Digital Interface), therefore program material source is limited; Again due to shortage data transaction door, therefore there is the popularization of valency data only to rest on, participate in program alliance and program exchange meeting, make the channel of potential user (as professional television program designing mechanism, the advertisement mechanism etc.) information that is short in understanding, therefore the channel of data recycling is very limited.
The 3rd, the limitation that new program form is supported.Following TV programme form and the mode of watching need to be more flexible, and spectators can be from seeing that Polarizations for Target Discrimination in Clutter is to participating in TV, adding TV community.Some new program forms are emphasized user's property of participation, wish to utilize multiple communication channel simultaneously with other televiewer by exchanging alternately, wish by multiple route of transmission transmission interchange content, and obtain the feedback information of TV user.And the operation system of existing full court planar network architecture is comparatively sealed, be difficult to provide the support to this pattern.
(3) to carrying out fast operational response, still there is limitation
Can not meet the demand of instant making and report program, so that social hotspots is made to fast reaction, assemble fast resource (equipment and manpower) and make whenever and wherever possible and produce corresponding program, and report.
(4) harmony and the business retractility of utilizing resource are still had to limitation
For each production subsystem, there is memory space, database and synthesis server and the transcoding server of oneself; All resilient expansion as required of these resources, and its utilance is unbalanced.And if can carry out to a certain extent the pool of infrastructure device resource, will greatly save equipment investment, and reduce to a certain extent the maintenance cost of each television station production system.
For the product platform interconnecting, each is produced between service sub-system and exists multiple network agreement to connect; In order to realize intercommunication, product platform is realized the resettlement copy work of the intercommunication of subsystem route, video/audio file by a large amount of migration server.The route of this mode is too complicated, and migration resource sharing degree is poor, and efficiency is also lower; The resources such as storage on product platform, transcoding, because the factor of management and route can only offer each subsystem as " near line resource ", and can not serve as the online resource of each subsystem, and extremely loaded down with trivial details to the invoked procedure of these resources, thereby utilance is low, uneconomical.
Known in sum, because following TV programme has polymorphic fusion, audient, play an active part in, issue and across various features such as media links by all kinds of means, and these forms are also in the process in development and creation.This just requires television station production system to possess enough adaptability to changes flexibly, is enough to support the development of the business of manufacturing with these features.Although and existing station synchronization production system supporting business reluctantly, but obviously can not adapt to demand quick, High-efficient Production, can not provide thus the powerful tool of production to be supported, cause a large amount of repeated system Constructions, and cause " the high-carbon operation " of system.
