Definitions
- the present invention concerns an automatic device for the delivering of video signals with a high capacity optical disks record.
- the cost first of all, the storage of a considerable quantity of video films requires a great space and this affects the extremely high costs of the present systems that make use of hard-disks as a storage support; slow loading and updating of the contents: the need of reducing the costs within reasonable limits requires the need of dimensioning the vide servers in such a way as to contain only those films that are to be broadcasted, storing all other films onto a tape and performing the loading thereof only when they are to be used.
- the loading of films from a tape is very long and may be compared to the duration of the films to be loaded.
- a server that generates 50 outlets e.g., can not send the same , veiy requested film on all 50 outlets, but a plurality of copies of saod film must be loaded. The same, it is impossible to send 50 different films each on one of the 50 different outlets, due to the limited capacity of the video server;
- the aim set forth is reached by means of the device according to the present invention, that makes use of DVD disks as a support for the storage of the films, while the different storage technology used allows to solve the problems shown by the conventional video servers when they are used for the realization of a NVOD service.
- the use of the DVD technology for the storage of the films to be broadcasted allows a cosiderable saving with respect to the magnetic disks. This allows to realize systems with a much greater capacity than the one of the systems based on hard-disks, and thus to solve the problems arising from a reduced capacity;
- - quick loading of the contents the capacity of the robotized record may reach 10,000 DVD, maintaining a maximum loading time of the DVD inside the readers of 7 seconds.
- the record composition mix may be quickly adapted to the requests of the users by loading a plurality of copies of the most requested films;
- analogic and /or digital outlet the proposed system may supply - according to the utilization ambient - a standard analogic outlet or a non-compressed digital one, as well as - in case of digital television - directly supply in output a compressed digital outlet MPEG-2 in singles or multiple program transport stream format, according to the DVB standard. This latter outlet allows to eliminate the need of the real time encoders MPEG-2, allowing further saving;
- a modular and expandible architecture the structure of the proposed system is extremely modular and maybe fitted from time to time to the needs of the user, choosing the capacity of the record, the number of the readers, the number ad the kind of the outlet cards. These parameters may also be modified in time for getting fitted to new arising needs.
- Figure 1 shows a block scheme of an automatic device for the delivery of video signals with high capacity optical disks record, according to the present invention.
- FIG. 2 shows a functioning scheme
- Figure 3 shows a digital outlet module
- figure 4 shows an analogic outlet module
- the enclosed figures show a device based on a robotized system 1 for managing a DVDs 2, responsible for the recording of films to be broadcasted and of their loading in DVD 3 readers which transfer the content 4 of the DVDs - a film in MPEG-2 format for each DVD - towards an output module 5 consisting of cards which, according to the use of the outlets, multiple a plurality of MPEG flows into one or more transport stream MPEG2 in accordance with the specifications of Digital Video Broadcasting, or transform each MPEG flow into a corresponding standard analogic outlet (compound, component or digital non compressed signal Dl), while the check system 6 coordinates the operations of te different components of said system and realized an interface with possible other scheduling or check systems.

- a robotized record DVD 1 that stores and mechanically manipulates a great number of DVD disks (up to 10,000).
- the use of this system eliminates all manual operations of loading from cassettes or tapes, with a consequent saving of time and money.
- the outlet data flow contains the video in MPEG2 format, one or more audio channels linked thereto and possible teletext or data channels.
- An outlet module 5 that integrates in a suitable way the cards for a non-compressed analogic /digital-like outlet and cards of the standard multiplex MPEG2 DVB kind.
- Cards for a non-compressed analogic and digital outled which convert the flow coming from the DVD readers into a standard television signal of the kind of PLA or NTSC, according to the features of the recorded video.
- the outlet of the card may be synchronized with other video signal sources (genlockable) and is usually supplied in compound, as an optional in components and in non-compressed digital.
- a card for digital MPEG-2 outlet that doesn't convert the flow MPEG-2 coming from the readers, but combines a plurality of flows containing one single film (single program transport strean) into one single outlet flow containing all films (multiple program transport stream).
- the outline of the card and the combinations of the flows are managed by the control system, according to the needs of the user.
- the outlet flow is supplied in a LVDS or ASI interface, as specified by the DVB standard.
- a control system 6 that controls and synchronizes the functioning of all components of the system, having one single external control interface. Therefore, the whole system is run through the control system, locally by means of a graphic interface or by a remote control on a serial or network interface.
- the control system has a record for storing the content of the DVDs present in the system so as to perform its control and coordination functions. Said record is automatically updated each time DVDs are loaded or cancelled from the system. Said record allows the search of the titles for broadcasting: once the titles is selected, the corresponding DVD in loaded in the reader. From this moment on the title may be broadcasted in outlet through the output cards. Also more complex operations are possible, like fast forward, pause, slow motion, fast backward, positioning to a specific time-code.
- the aim of the system is to supply a plurality of video outlets, of different kinds, independent one from the other and corresponding to as much DVDs loaded in the readers, the presence of further surrounding functions seems to be required for realizing this particular function, and they are grouped according to their single components as follows: - robotized DVD 1 record: it has an external interface and all running and monitoring functions are run by the control system:
- an outlet module 5 that integrates in a suitable manner the outlet cards of the non-compressed analogic/ digital kind and of the standard multiplex MPEG2 DVB kind.
- the functions performed by the different kinds of card are:
- control system 6 that manages and synchronizes the functioning of all components of the system and that has one single external interface; consequently, the control system must be able to send all orders relative to the functions available in the different under-systems and possibly to translate the orders coming from outside into orders intelligible by said under- systems.
- an order coming from outside might be: ⁇ ou will send film X to outlet Y. This order must be converted in the following sequence of controls:
- control system For performing this complex function, the control system must also be able to run and to signal possible error situations due to bad working or to wrong orders.
- the main functions of the control system are:
