Definitions
- This invention relates to media management systems. Aspects of the invention relate to managing data in the media management system and in particular, but not exclusively, to managing data for transmission.
- media intake 1 (for example from wire feeds) is received by a newsroom computer system (NCS) 2 which may comprise, for example ENPS (Electronic News Production System) software.
- ENPS is a system for use in the creation of news stories for broadcast; journalists use segments of the input items and perform various operations using ENPS to create news stories for broadcast.
- the news story may combine several media objects, for example video, text and graphics and ENPS can be used to create a script for the story as well as programme timing, running order, edits and other information.
- ENPS sends out data to a transmission system 3 for transmission of the story.
- the transmission system 3 comprises several playout devices or media object servers, for example video device 4, audio device 5, graphics device 6, banner device 7 and autocue 8.
- ENPS sends a command to each of the required media object servers with the relevant tagged media items. Thus a connection is required to each media object server from ENPS.
- NCS may communicate with each media object server, for example where more than one newsroom is creating stories for broadcast using the media object servers.
- Each of the NCS will send commands to each of the media object servers, as required, in the transmission of the story.
- the different media devices linked to the NCS require commands in different communications formats, for example different protocols or different versions of the same protocol, and thus communication with the NCS is complicated by the requirement for translation of messages by the NCS in dependence on the media device to or from which the communication is sent or received. In extreme cases, communication between devices requiring different protocols may not be possible. Even where a common protocol, such as MOS (Media Object Server) Communications Protocol is used, the playout devices may each be running different versions of the protocol. Thus it is often the case that data is required to be translated to a different format in dependence on the machine it is being sent to or from which it has been received, further putting a burden on the NCS and giving great scope for errors in communications to occur.
- MOS Media Object Server
- a media item which might be handled in a media management system generally comprises separate media objects or tracks, for example video, and audio.
- the tracks can be referred to as media essence.
- Media items can additionally comprise metadata, which describe attributes associated with a media item, and which is used to assist in processing of the media essence within the system eg. storing, tracking, editing, archiving etc.
- a media item can therefore be said to be made up of media essence (tracks), and associated metadata (attributes). While essence and metadata are associated they are usually used and stored separately and independently in the system.
- a media object generally includes a very large amount of data.
- the media essence - which may include video at broadcast quality resolution - requires a particularly large amount of storage.
- Stories may be completed by journalists a long time in advance of the planned transmission time, and the playout servers may hold at any one time a very large amount of data relating to media objects to be transmitted at a future time. This can lead to a storage capacity problem on the servers in the transmission domain.
- a method of managing data for transmission in a media management system comprising a data storage device and a transmission system, the method comprising: identifying data in the data storage device relating to a transmission by the transmission system; defining a scheduled transmission time for the transmission; defining a transfer time based on the scheduled transmission time; and loading data from the data storage device into the transmission system at the determined transfer time.
- the transfer time can be determined such that the data is loaded into the transmission system on a just-in-time basis.
- the data storage device may be located, for example, separately from the transmission servers. In preferred examples, the storage device is located as a part of the editing domain.
- the data comprises data for transmission.
- the data comprises media essence, for example audio or video tracks.
- Such media requires a relatively large amount of storage capacity at the transmission servers and thus significant reduction in storage capacity can be achieved by delaying the loading of the media essence to the transmission servers.
- the data which is loaded at the determined transfer time may comprise some or all of the relevant data relating to the transmission. For example, only the loading of data requiring the greatest storage capacity at the transmission system might be delayed by this method. For example, the loading of video tracks only might be delayed, or the loading of all media essence might be delayed.
- the loading of the data might be managed in dependence of other factors, for example the available storage capacity at the transmission servers.
- media essence may include, for example, video tracks which can use much storage.
- the data storage device is also accessible by the editing system and may be a part of the editing system. This feature is particularly attractive since the media essence need only be stored once in the system during editing and until it is loaded into the transmission system just before transmission. Thus the data is already present in the editing domain and therefore presents little storage burden there while it is waiting to be loaded onto the playout servers.
- the data may be loaded a predetermined time before the scheduled start of the transmission.
- the available storage capacity of the transmission servers could be a factor.
- Other factors could include the size of the data file to be transferred, the type of data, type of programme being transmitted, and/or other factors.
- the transfer time is defined as a set time period before the scheduled transmission time.
- the determined transfer time will generally be set to occur before the scheduled transmission time so that the data is available for the transmission.
- other factors are taken into account, for example the status of the transmission system, for example the available storage capacity, the status of the connection between the storage device and the transmission system, the size of the data files to be uploaded, the type of transmission (for example its level of importance), and/or other factors.
- This the transfer time may, for example, be a set period of time before transmission which is applied to all of the transmissions.
- different time periods could be set for different transmissions, or different types of transmission.
- data relating to news broadcasts might be allocated a different time period from other programmes.
- Different periods could be set for different times of day, or in dependence on other factors, for example the available storage capacity of the transmission system. For example, at night, there may be fewer transmissions, and thus less demand on the transmission servers; at night, the predetermined time period might be longer than in the daytime.
- the method further includes the step of determining an estimate of the storage capacity of the transmission system, and defining the transfer time based on the estimated storage capacity.
- the method includes the step of determining whether the necessary data has been loaded into the transmission system, and, if not, initiating loading of the necessary data.
- the step of determining whether the necessary data is loaded into the transmission system is carried out at a predetermined time before the scheduled transmission time. Thus this determination can provide a back-up check to ensure that the necessary data is available in time for transmission.
- This check may be carried out by the transmission system, the editing system, or other part of the media management system.
- the transmission system initiates the loading of the data.
- the transmission system is adapted to call for the loading of the relevant data at a predetermined time. Such a call may be made, for example, to a media editing system or data storage device
- the loading of the relevant data may be initiated by a different part of the media management system.
- the media management system further comprises a media editing system, and the media editing system initiates the loading of the data to the transmission system.
- a media editing system initiates the loading of the data to the transmission system.
- a preferred arrangement may use a combination of these methods
- the method includes the step of identifying a command for transmission of data, determining data associated with the transmission and determining the transfer time for that data.
- the system is adapted to monitor communications to look for messages including commands for the transmission of data. When such a command is identified, the system preferably determines whether there is data associated with the command to be loaded to the transmission system and, if so, determines a transfer time for the data.
- This feature can also be used to provide a back-up system to help ensure that the necessary data is available in the transmission system for transmission at the appropriate time.
- a check is preferably carried out to determine whether the necessary information has been loaded into the transmission system and/or whether a transfer time for loading the data has been determined.
- a further aspect of the invention provides a method of managing data for transmission in a media management system comprising a transmission system, the method comprising: producing data for sending to the transmission system, and determining a delay before sending the data to the transmission system based on the scheduled transmission time.
- the media management system comprises an editing system for communication with the transmission system, wherein the method includes routing communications between the editing system and the media devices through a router.
- a further aspect of the invention provides a method of managing data in a media management system comprising an editing system and a transmission system, wherein the management system further includes a router and the method comprises routing communications between the editing system and the transmission system through the router.
- a more transparent, resilient and extensible system can be provided.
- the system can be extensible in that further media devices can be attached.
- the transmission system preferably includes broadcast production apparatus and equipment; the transmission domain may be external to the editing domain or may be a part of a single system.
- the transmission system comprises a plurality of media devices, the router routing communications between the editing system and the media devices through the router.
- the media devices include one or more playout servers.
- the media device comprises a media object server, preferably adapted for communication using the MOS communication protocol.
- the media devices may comprise for example video servers, audio servers, still stores and character generators.
- the editing system comprises a plurality of editing devices.
- the editing devices include newsroom computer systems (NCS) which may comprise for example ENPS (Electronic News Production System) software.
- NCS newsroom computer systems
- ENPS Electronic News Production System
- the router can be used to connect simply a plurality of NCS and a plurality of media devices.
- the method comprises monitoring the communications routed through the router and outputting information regarding the communications.
- One of the disadvantages of previous systems is that there was no central log of communications passing between the editing and transmission domains. By using a router, the communications passing through the router can be logged and diagnostics information outputted.
- the router can also have further benefits, for example enabling central access to the media devices.
- the router can be used to trigger commands to the devices from a central point.
- the router can also be used to monitor commands, for example passing between the editing domain and the transmission domain.
- the router can be used to identify commands being sent to the transmission system to effect transmission.
- the router initiates the loading of the data to the transmission system.
- the router has the function of a playout manager, managing the loading of data to the transmission system.
- the router monitors commands relating to the transmission of data, and determines a transfer time for loading the data to the transmission system on the basis of the scheduled transmission time of the data.
- the router can preferably monitor commands being sent from the editing system to the transmission system and identify commands relating to the transmission of data. From these commands, the router can preferably determine the scheduled transmission time for the data and the identity and location of the data to be transmitted.
- the router can determine a transfer time for loading the data to the transmission system on the basis of the scheduled transmission time of the data. Preferably the router determines whether data for a scheduled transmission is loaded into the transmission system. This step may be carried out in addition to the determination of the transfer time, and may, for example, provide a back-up system for checking that the necessary data is available in the transmission system. Such a check may, for example, be carried out at a predetermined time before the scheduled transmission time of the data.
- the router initiates loading of the data for transmission to the transmission system at a determined transfer time.
- the router sends a communication to a data storage device to initiate the loading of the data.
- the router is in communication with the media store which holds the media essence for transmission with media items. This is of great potential benefit in that the router can act as a playout manager for the transmission of data and can manage the loading of data to the transmission devices.
- the router can receive information on the running order for transmission and can send commands to the media store to load data for transmission into the transmission domain.
- the router is preferably provided as a separate device although it may be incorporated into the system as software, for example in the editing domain, transmission domain, or elsewhere.
- the router has a single IP address.
- the connection information for the media devices can therefore be held centrally at the router.
- the router translates communications from a first format to a second format.
- the router is preferably adapted to translate messages to/from the editing domain to different formats in dependence on the media device to/from which the message is sent.
- the translation may be between, for example, different versions of the same protocol, or between different protocols.
- the communications between the router and the media devices are according to the MOS communications protocol.

- Figure 6 is a schematic representation of an example of editing and transmission domains in a media management system.
- News staff use a media management system to research, develop and produce news stories comprising media items.
- a metacore 200 is at the centre of the system, and comprises a metadata store 201 and a media store 202.
- Media intake for example from video feeds, agencies, newsgathering teams etc. can be received via an edit matrix 206 which is controlled by a network control system 208.
- metadata values which are stored in the metadata store.
- Media intake can also be received from viewing and editing services 210 and Archive service 212.
- the metadata values may be imported with the incoming media, may be assigned values by a system operator or may be assigned default values.
- the associated media is then stored in the media store 202.
- Users of the system can use viewing and editing services 210 to view and edit media managed by the system, and can search the system by metadata attributes to find relevant media. Once the relevant metadata describing the desired media has been found, the system can retrieve the associated media from the media store (if it exists there) for use by the user. Users can create new media items from existing essence, but with new metadata (which may be derived from existing metadata) to be input into the metacore.
- the media store is an online store, and media held within it can be accessed and manipulated directly via devices networked to the metacore.
- the practical constraints of media storage dictate that only a certain volume of media can be maintained online in this way, and as new media is constantly fed into the system, existing media must be removed. This is particularly true of the media essence, and less so of the metadata. If it is determined that the media is important and cannot simply be deleted, it must be stored offline, or archived. Both the process of selecting material to be archived, and the process of archiving it require considerable resources.
- An archive service 212 is therefore linked to the metacore.
- the archive service is in turn linked to one or more VTRs 214.
- the archive service identifies media, via its metadata, to be taken from the media store and recorded to tape (offline).
- the archive service can also act to re-ingest into the (online) media store tape based media.
- the metacore is connected to transmission servers 216. These transmission servers can accept media items which are to be broadcast on transmission system 218.
- the system also supports web based output, and the metacore is further linked to a post processor 220 which in turn feeds a web hosting 222.
- the routing of video, audio, and communication signals between various media systems and facilities, both internal and external, can be referred to in terms of 'Bookings'.
- a Booking may simply specify a media feed from one location that is to be routed to another location, internal or external to the media management system. Bookings may also include recording of the media being routed. For example, a booking may be made to enable an on-air news presenter to interview someone live at a remote location. Bookings can also be communications only bookings, enabling staff from various locations to communicate via a dedicated communication link. Any tasks that require recording or playout of media can be tracked as a booking.
- all media items and media essence contained in the system are either the result of recording from the edit matrix, or from the archive service, or imported from the Editing services.
- a variety of recording methods are supported by the system, including methods for media sources that must be recorded live from within the news facility, from a tape source, or an Agency feed.
- All of the media items recorded into the system are assigned metadata.
- the different types of metadata assigned to media items may vary according to the particular item. This metadata is assigned by the Mediaport or by Mediaport staff.
- the metadata may be automatically imported from an external source, assigned by the Mediaport, or automatically assigned a default value.
- the metacore 1702 includes a client side applications group 1704, a media service 1706 including a media store, an applications server 1708 and a metadata store 1710.
- Client applications are written in C++ and communicate using J2EE (Java 2 Platform Enterprise Edition) component level communications (JNI-RMI invocations), J2EE messaging and ' que ⁇ ing, (JMS via Active JMS).
- Server applications including system management applications could be written in either Java or C++.
- Media storage, transfer and editing will typically be provided by a third party media system and associated protocol running on a gigabit Ethernet. The components of the metacore all run off a media gigabit Ethernet.
- the metacore is linked to the transmissions domain 1712 by a transmission gateway 1714.
- the transmission gateway will communicate with the Transmission domains using the appropriate MOS protocol.
- Input feeds are routed through the Spur Central Apparatus Room (SCAR) matrix 1714 to the edit matrix 1716, for ingest into the metacore.
- SCAR Spur Central Apparatus Room
- the edit matrix features a filter comprising a dual redundant pair of PCs managing, filtering and auditing control requests from the system and transmission domains. Both the SCAR matrix and edit matrix are controlled by Broadcast
- BNCS Network Control System
- the CBIS will be configured to replicate to the Metadata Core on a regular basis (typically ⁇ 1 min).
- the Metadata Core will then update any application screens reliant on data that has changed.
- system clients will be implemented as Win32 native clients 1802. As such a mechanism must be provided to allow the clients to communicate with the J2EE application server 1804. The client server communications will be facilitated via use of a Java-C++ bridge 1806.
- the C++-Java Bridge allows C++ proxy stubs to be generated from Java classes. This allows any C++ client to behave exactly as a standard Java client.
- a thin C++ wrapper will be provided (generated) around the required J2EE client API's (Application Program Interface) to allow the client to access components on the application server.
- the C++-Java Bridge will be used to generate C++ proxy stubs for the EJB (Enterprise Java Bean) remote and home interfaces, thereby, allowing the client to perform interaction with the application server in the same way as any Java client would.
- Certain client views are required to receive events from the application server (e.g. notification on booking status changes). These will be sent to the clients in the form of JMS messages via JMS Service 1808 from the application server.
- the C++-Java Bridge will convert the message into an event and the appropriate action can then be taken by the client application.
- the client may register interest with any number of event topics. This will allow the client to receive events that represent actions performed by various metacore services.
- the payload of the message will vary depending on the type of event fired by the service and will include all the information required by the client to perform the required action.
- the metacore is linked to the transmissions domain 1712 by a transmission gateway 1714.
- the transmission gateway will communicate with the
- Figure 5 illustrates communication between the editing domain 11 and the transmission domain 13 in the media management system.
- the NCS devices 10, 10', 10" in the editing domain communicate with a router 12 which routes messages between the editing domain 11 and MOS devices 14, 14', 14", 14'" in the transmission domain 13.
- the router 12 comprises a MOS router having a single IP address and TCP/IP links to the NCS 10, 10', 10" and the MOS items 14, 14', 14", 14'".
- each NCS sends messages to a single object (the router) and the router then sends messages to the MOS items 14 using the MOS communication protocol.
- the router 12 logs all of the communications through the router between the NCS and MOS items and provides an output giving information regarding the communications.
- FIG. 6 shows the communication between the editing 121 and transmission 119 domains in more detail.
- TCP/IP links 100 connect NCS 120 to a MOS router 112.
- the MOS router 112 is shown as connected by further TCP/IP links to four playout servers 113: video server 115, an autocue 116, a graphic banner generating device 117 and a graphics device 118.
- a desk 122 provided downstream of the MOS objects provides the possibility of manual control of the data before broadcast, but is optional. Messages are sent from the NCS 120 to the router 112 at a single IP address.
- the router includes connection information for all of the relevant MOS devices.
- a data storage device 130 which includes media essence for use in the creation of stories for transmission.
- This data storage device 130 is accessible by the NCS 120, for example for use during the editing and creation of media items and stories, and is also arranged such that data can be loaded from the data storage device 130 into the transmission devices 113.
- a link between the router 112 and the data storage device 130 allows control of the data in the storage device 130 by the router 112, and in particular allows the router to initiate loading of the data for transmission into the transmission devices as described further below.
- the data storage device 130 is shown in Figure 6 as being separate from the editing system 121, but the storage device may be provided as a part of the editing system 121.
- a Journalist creates a story for transmission within NCS 120 (using ENPS).
- the story includes video elements, graphics and text for an autocue; the journalist creates media attributes relating to the story (for example script, running order and edits required).
- a running order is created in ENPS from the stories; as stories are finished, they are added to the running order.
- the stories created contain attributes and not the essence, for example the actual video clip, although such essence can be accessed by the journalist for reference in the creation of the story.
- the essence is stored in the data storage device 130.
- the running order can remain dynamic until it is sent to the transmission domain 119.
- the sending of the running order may occur once the running order is complete, or can be held in the NCS until a predetermined time before the scheduled transmission time for the stories of the running order, for example one hour before the first item of the running order.
- the running order can be sent to the router 112 once it is complete and the router may delay sending the information to the transmission domain until a desired time before the scheduled transmission time.
- the running order will not normally include any media essence.
- This essence will be stored in media stores, for example media store 130.
- This media essence must be transferred to the playout servers 113 before the transmission of the story can occur.
- the NCS first sends the running order to the playout servers 113 via the MOS router 112 in advance of the transmission time for the relevant stories. This transfer occurs as soon as the running order has been completed, or may be timed to occur a predetermined time before the transmission time.
- the NCS 120 sends a command to the media store 130 to load the required essence into the playout servers 113 for the stories of the running order.
- This command may, for example, be sent half an hour before the transmission time for that portion of the running order.
- the playout servers 113 can be adapted to request the loading of the relevant data prior to transmission. Since the running order has already been sent to the playout servers 113, the essence required to transmit the relevant stories is known, and the playout server sends a command to the media store 130 for the required data.
- the loading of the data is initiated by the router. The router identifies the essence required by the playout servers 113 in respect of each story to be transmitted. At a predetermined time before the transmission time, a command is sent to the media store 130 to load the required essence into the playout servers 113.
- the router effect the loading of the data into the playout servers. In this way, it is possible to ensure that the master data is always loaded into the playout servers for broadcast, rather than a derivative version, so that resolution is not compromised. It is to be noted that the essence to be transmitted is likely to have been viewed using the NCS by the journalist during the creation of the story, but the data viewed by the journalist is normally a lower resolution version of the data. It is clearly desirable that it is not this low-resolution version which is sent for transmission.
- a preferred technique might include more than one of the methods described above.
- the NCS or router may be programmed to send the commands for loading the required data into the playout servers 113, but as a backup, the playout servers 113 may be programmed to request the loading of the information themselves if they have not received the necessary data within a predetermined time before transmission-is due.
- the NCS may be programmed to effect the loading of the required information into the playout servers half an hour before the transmission time.
- the playout servers are programmed to carry out a check 15 minutes before the transmission time to determined whether all of the necessary information has been loaded and, if not, to request the missing data from the media store 130. This missing data may represent some or all of the data required for a particular transmission.
- the system is easily extensible, by adding further MOS objects, or NCS.
- MOS objects need not all require the same format of communications; the MOS router can provide dynamic filters which can interpret messages between the playout servers and the NCS.
- the router can provide on-the-fly translation of messages, for example between different versions of MOS and/or between
- the running order is sent via the router 112 to the playout servers 113.
- the router 112 monitors the message and notes that it includes a command for the transmission of video data by the video server 115.
- the router 112 determines from the message the following information:
- the media device to transmit the data (in this case the video server)
- the router 112 may also determine some or all of the following information: ⁇ the type of transmission (for example "evening news item")
- the router 112 uses some or all of this information to determine a transfer time for loading the data to the video server. This transfer time will be before the scheduled transmission time and will be chosen such that the data is available in the video server prior to the transmission time and yet the video server storage devices are not loaded with data before it is required.
- the router sends a command to the data storage device 130 to load the required information to the video server.
- the router carries out a check to see whether some or all of the data to be loaded is already present in the video server. If it is, then the loading of the data is adjusted accordingly.
- the router carries out a further check of the video server to determine that the required data has been loaded. If it has not, then further steps can be taken to effect loading of the data in time for the transmission.
- data may be sent to the transmission system, for example from the editing system through the router.
- the router can delay the loading of that data into the transmission system.
- the router can store the data (for example the data can be sent for storage to the storage device 130) and can determine a transfer time for transferring the data to the transmission system.
- the router can identify the change and send commands to effect loading of the new data required to the playout server.
