UNT UPDATE NOTIFICATION TABLE

SSU server can generate multiple UNT sub tables that each have a unique OUI (i.e. two sub tables can't use the same OUI value). Currently all UNT sub tables are sent on a single PID. To edit UNT PID, select UNT from server tree and click on the Set UNT PID button in the tool bar.

A data broadcast id descriptor is generated automatically to PMT for the UNT PID. OUI of each UNT sub table will be listed in the descriptor and version information for each OUI in the descriptor will be generated using the version number of the corresponding UNT sub table. Additional PMT descriptors can be added for the UNT PID by clicking on Edit PMT descriptors in the UNT sub tables tab.

The following information for an enhanced profile SSU data carousel will be inserted to the selected UNT sub table when a stream for the data carousel is started:

• Compatibility descriptor for each carousel group. This is equal to the compatibility descriptor that is inserted to the DSI group info of the DSM- CC data carousel.
  
• Target and operational descriptors for each carousel group.
  
• SSU location descriptor for each carousel group. This will associate the group to a data carousel PID using carousel's component tag.
  

For more information about starting carousels, see Managing DSM-CC Carousels -chapter.

ADDING SUB TABLES

To add a new UNT sub table, select UNT from server tree and click on the Add UNT sub table button in the tool bar. A dialogue (see figure 3.1) is presented with the following options:

Figure: Adding a UNT sub table

• OUI: IEEE OUI value that will be used for this sub table. OUI value is unique (i.e. two sub tables can't use the same OUI value).
  

EDITING COMMON DESCRIPTORS

Each UNT sub table has a list of descriptors that will be inserted to the common descriptor loop of the sub table. To edit this descriptor list, first select UNT from server tree. Then right click on a sub table in the list under the UNT sub tables tab and select Edit Common Descriptor. A dialogue that allows you to modify the descriptor list is presented.

SSU DATA CAROUSELS

SSU data carousel is a two-layered DSM-CC data carousel that is sent on a single PID. Carousel consists of groups that contain the carousel files.

1. ADDING CAROUSELS

To add a new SSU carousel, select SSU carousel repository from server tree and click on the Add new carousel button in the tool bar. A dialogue (see figure 4.1) is presented with the following options:

• Name: A descriptive name that is used only in PMC. Name must be unique, i.e. two carousels may not have the same name.
  
• Scheduled: If this checkbox is selected when creating the SSU carousel, the groups of that SSU carousel are deactivated be default and are activated by scheduler. In the UNT Operational Descriptors -window (for group) it is possible to add Scheduling descriptor and edit its parameters.
  
• SSU profile: Simple profile or UNT enhanced profile. UNT information is generated only for enhanced profile carousels.
  
• Bit rate: Transport stream bit rate for the DSM-CC data carousel in bits per second.
  
• PID: Transport stream PID for the DSM-CC data carousel. If auto is selected, PID will be automatically assigned when the carousel is started.
  
• Componenttag:Component tag that is used in UNT and PMT tosignal this carousel. If auto is selected, component tag will be automatically assigned when the carousel is started.

2. ADDING GROUPS

Every file in an SSU carousel must belong to a group. Each group corresponds to a group in the DSM-CC carousel's download server initiate (DSI) message as well as to a DSM-CC download info indication (DII) message. All data in a group is typically for one manufacturer, but one manufacturer can have multiple groups for multiple updates.

To add a new SSU carousel group, select a carousel from server tree, then select the Groups tab and click on the Add group button in the tool bar. A dialogue (see figure below) is presented with the following options:

Figure: Adding a group to an enhanced profile SSU carousel

• Name: A descriptive name that is used only in PMC. 
  
• OUI: OUI value used in DSI group info.
  
• UNT: UNT sub table where this carousel will be signalised. This option is shown only for UNT enhanced profile carousels.
  
•

• Add hardware descriptor: Check this if you want to add a hardware descriptor to DSI compatibility descriptor. Compatibility descriptor can also be edited later, for more information see Editing Compatibility Descriptor on page 23.
  
• Model: Value of the model field in DSI compatibility descriptor.
  
• Version: Value of the version field in DSI compatibility descriptor.
  

EDITING COMPATIBILITY DESCRIPTOR

To edit compatibility descriptor for an SSU carousel group, select the carousel from server tree and then select the Groups tab. Right click on a group and select Edit Compatibility Descriptor. An editor dialogue will appear, for more information about using the editor, see Editing PSI/SI Data Structures on page 32.

EDITING UNT DESCRIPTORS

To edit UNT target and operational descriptors for an SSU carousel group, select the carousel from server tree and then select the Groups tab. Right click on a group and select Edit Target Descriptors or Edit Operational Descriptors. An editor dialogue will appear, for more information about using the editor, see Editing PSI/SI Data Structures.

ADDING FILES

To add a new SSU carousel file, select a carousel from server tree, then select the Files tab and click on the Add file button in the tool bar. A dialogue (see figure below) is presented with the following options:

Figure: Adding an SSU carousel file

• Group: group where this file will be added.
  
• Path: local path for the file to upload to the server.
  

EDITING MODULE INFO DESCRIPTORS

To edit DII module info descriptors for an SSU carousel file, select the carousel from server tree and then select the Files tab. Right click on a file and select Edit. An editor dialogue will appear, for more information about using the editor, see Editing PSI/SI Data Structures.

For more information about using the editor, see Editing PSI/SI Data Structures.

RUNNING CAROUSELS

To start a carousel, you have to attach it to a service, i.e. create a stream for it. To create a stream, right click on a carousel in the server tree and select Attach to Service.... For more information about streams, see Managing DSM-CC Carousels.

SSU TRANSPORT STREAMS

SSU transport stream files are externally generated transport stream files that are played out from the Playout SSU server.

ADDING TRANSPORT STREAM FILES

To add a new SSU transport stream file, select SSU transport stream repository from server tree and click on the Upload transport stream file button in the tool bar. You are prompted to select a transport stream file that will be uploaded to the server. When you have selected the file, a dialogue (see figure below) is presented with the following options:

Figure: Adding a transport stream file

• Name: A descriptive name that is used only in PMC. Name must be unique, i.e. two transport stream files may not have the same name.
  
• Input PID: Data PID in the input file.
  
• Output PID: PID that will be used when sending the file. If auto is selected, PID will be automatically assigned when the carousel is started.
  
• Bit rate: Transport stream output bit rate in bits per second.
  
• PMT descriptors: Descriptors that will be added to PMT when this file is started. For more information about using the editor, see Editing PSI/SI Data Structures.
  

RUNNING SSU TRANSPORT STREAMS

To start a sending transport stream file, you have to attach it to a service, i.e. create a stream for it. To create a stream, right click on a transport stream file in the server tree and select Attach to Service.... For more information about streams, see Streams and Timers.
