Some D3&4 errors are now fixed.

Current status is:

services present in the EITpf on BBCA but missing in D3&4
nit version_number = 17
TSID SID LCN service_name
8008.8200 206 POP
8008.8240 208 POP MAX

800B.8240 208 POP MAX
800B.82C0 207 Tiny Pop
800B.8540 069 LEGEND XTRA
Total = 8


This is off Winter Hill which is rather unusual in transmitting three Local Multiplexes.

I think the above are likely missing because they each have the same SID in each multiplex.

On the Liverpool Multiplex, only TalkLiverpool is in the D3&4 EIT.

On the Manchester Multiplex, only That's TV is in the D3&4 EIT.

All services in the Preston Multiplex are present in the D3&4 EIT.

The Freesat Streams are mapped to every Freesat service in the Program Map Table of the service.

The PMT is a list of the streams that comprise the program and corresponds to the components list helpfully given in the ASTRA EIT.

The streams are streams of packets with the same Packet ID or PID, each consisting of a 4 byte header that indicates the PID and a 184 byte payload.

The Freesat Streams PIDs can have any value so stream descriptors are used to indicate a stream is a Freesat Streams and the kind of stream it is.

Unfortunately, something has gone awry with the three ITV HD transport streams such that these descriptors are missing for FSAT EIT pf and FSAT NIT.

The three ITV HD transponders that had missing descriptors for some Freesat streams are now fixed.

These are the Freesat stream PIDs as indicated by the stream descriptors:

transport_stream_id = 2063
11052.75 H
fsatPids
eit = 3842
eitpf = 3843
nit = 3840
sdt/bat = 3841
tdt/tot = 3844

transport_stream_id = 2064
11067.50 V
fsatPids
eit = 3842
eitpf = 3843
nit = 3840
sdt/bat = 3841
tdt/tot = 3844

transport_stream_id = 2066
11097.00 V
fsatPids
eit = 3842
eitpf = 3843
nit = 3840
sdt/bat = 3841
tdt/tot = 3844

The streams that had missing descriptors were eitpf - used for recording by running status, and the nit - which contains a descriptor pointing to FreesatHome

This evidently led to failure to record and failure to load the EPG on boot up off FreesatHome.

What is curious is that it apparently did not affect all boxes.

It could be the case that the Freesat stream PIDs are now fixed, so the descriptors are only needed by legacy Freesat devices.

It is a fact that, at this time, the only transponders with different Freesat stream PIDs are these:

transport_stream_id = 2108
11265.00 V
fsatPids
eit = 3844
eitpf = 3841
nit = 3843
sdt/bat = 3842
tdt/tot = 3840

transport_stream_id = 2024
12168.00 V
fsatPids
eit = 3841
eitpf = 3842
nit = 3840
sdt/bat = 3844
tdt/tot = 3843

The Freesat services carried 12168.00 V are:

BBC ONE So HD [BBC One South HD]
CNBC
ITV1 HD [Central West]
Channel 4 HD [Midlands]
Channel 4 HD [North]
