- PortTarget: Target port related to the streaming service.
Meanwhile, the information presented for a MPTS service is the same except Components and TstreamId, being
substituted by the frequency information.
The parameters associated to a streaming service can be modified, whenever this service is not running, making a double
click on it, or executing the “Stm Services/Modify Streaming Service” menu option.
2.4.3.1. Definition of a streaming service from an existing service/transponder in database
This way to define a streaming service is the more common. From “Database” tab, we select the service or services that
we want to define as streaming services. These services pass to the “Streaming Services” clicking on the icon , or on the
menu option “Services/Create Streaming Service(s)”. In MPTS mode we can only add a service, but in SPTS mode it is
possible to add up to eight services in the same transponder.
In SPTS mode, by default, the application adds up the services only with video and audio PIDs (plus PCR PID); but if the
user wants to create the services with all the PIDs that make up them, from “Database” tab, he has to select the menu
option “View/Advanced View”, and with the service(s) selected, pulse the menu option “Services/Create Streaming
Service(s) with ALL PIDs”. You have to be careful with this alternative because you can add up PIDs that are not
necessary for our goal, and run out the device hardware resources; so, if you want to add up any PID different from video
or audio, we recommend you add up these PIDs modifying the service created with only video and audio PIDs (menu
option “Stm Services/Modify Streaming Service”).
In order to add up the information of some descriptors included in the original PMT associated to the service, we should
activate “Enable PMT Descriptors” tick and select those we want to introduce. When a descriptor is added, the possible
component or components associated are also added; this is the case of the teletext descriptor: if we add the teletext
descriptor (tag 0x56), the component or PID that contains the teletext data is added up.
A streaming service defined like this, initially presents a “No Config” state and all video and audio PIDs that make up the
original service. The generated IP Target belongs to the multicast address range and follow the rule configured and
explained in the paragraph 8.2. The default value for Port Target is 20000. The default Streaming Mode is SPTS-UDP o
MPTS-UDP depending on the operation mode.
2.4.3.2. Definition of a streaming service from an existing streaming service (SPTS)
In order to define a streaming service from an existing one, we have to select this one and copy it, clicking on the menu
option “Stm Services/Copy Streaming Service”.
Once it is copied, the new service will be in the list as a copy of the former but with the PIDs field unassigned. Before the
new service can be started, it is necessary to edit the PIDs field. The definition of the rest of the parameters for the new
service will follow the rules seen in previous paragraph.
2.4.3.3. Definition of a streaming service with no previous service reference (SPTS)
In order to define a new service, we have to click on the menu option “Stm Services/Add New Streaming Service” (
).
The following window will pops up with different tabs “General Information”, “PIDs Information” and “Descriptors
Information”:
