Hi guys,

I found the following code in the descriptors declarations:

class lcn_service_descriptor_loop_item(DVBobject):

def pack(self):
fmt = "!HH"
return pack(fmt,
self.service_ID,
((self.visible_service_flag << 15) | 0x7C00 | self.logical_channel_number),
)

However for nordig LCN, the logical_channel_number field is expected to be 14 bit, not 10 bit. Has anyone done any alterations to this which allow nordig compliant LCN generation?

Thanks! Jules

Don't worry, cracked it. Made a new descriptor as follows:

class lcn_service_descriptor_14_loop_item(DVBobject):

def pack(self):
fmt = "!HH"
return pack(fmt,
self.service_ID,
((self.visible_service_flag << 15) | 0x4000 | self.logical_channel_number),
)

Now the LCN is respected when 14 bit logical_channel_number field is expected...
