[edit] Main concepts
Check the readme.txt file provided by the people of JustDVB-It.
read about MPEG transport stream.
[edit] How JustDVb-It works
1- Generate the psi tables.
2- Generate events and carrusels.
3- Muxes elementary streams, carrusels and psi tables to obtain a transport stream.
4- Plays the generated transport stream.
[edit] Recipes
[edit] Quickstart
Buy a DTA-110T board and download the JustDvb-It live cd at CINECA web site.
[edit] Adding applications
Edit psi-config.py placed in bash-config folder
1- Follow application3 by this
myNewApplication = application_loop_item( # <<<<<<<<<<<<
organisation_id = 10,
application_id = 1003,
application_control_code = 2, # PRESENT
application_descriptors_loop = [
transport_protocolB_ds,
app_ds_b,
application_name_descriptor(application_name = "My new application"),
dvb_j_application_descriptor(parameters = ["dvb://1/sample9"]),
dvb_j_application_location_descriptor(
base_directory = "/",
class_path_extension = "",
initial_class = "myNewApplicationFileClassName",
),
]
)
2- Add new application to the AIT
ait = application_information_section(
application_type = DVB_J_application_type,
common_descriptor_loop = [],
application_loop = [ # <<<<<<<<<<<<
application1,
application2,
application3,
myNewApplication,
]
)
3- Place in ocdir1 a myNewApplication.class file which implements an Xlet
4- Excecute transport-generator.sh
[edit] Adding audio and video
[edit] Creatting channels
- Add another PMT and some (elementary stream)
- Link it to PAT
- Add in the SDT the service name
- Add a couple of "tsloop" in the transport-generator.sh file
