Setting up the Transport Stream Output (TSO)

Set-up Procedure

Page 3 of Menu #11 is used to allow the transport stream for the current
service to bypass the CA module on its way to the TSO module.
Table 3.13: Setting up the Transport Stream Output (TSO)
Step Action
1. In Menu # 11 (Data), go to page 3.
2. If the Alteia is appropriately authorised, and the TSO selection is DECRYPTED,
then the transport stream passes through the CA module as follows:
·
·
·
·
If the transport stream output is to remain encrypted, choose the ENCRYPTED
option.
For VideoGuard, only components of the currently selected service, which is
being successfully decoded and decrypted by the IRD, will be presented to the
TSO in their decrypted form.
A maximum of 6 components, all from the same locally selected service will be
passed to the TSO in their decrypted form. If a service contains more than 6
components, the remainder will stay encrypted. (see table C.22, [Menu 10,
pages 11 and 12] for instructions on selecting which components remain
encrypted).
The Semi-decrypted output contains the original, unmodified SI, PSI and CA
information. This includes CA descriptors of the currently selected service. This
should be considered when feeding downstream re-mux type products.
This restriction does not applied to RAS decryption where the entire transport
stream can be decrypted.
3. Press SAVE to store the choice.

Packet Lengths

The output is an MPEG-2 bit-stream from the received services.
The output packet length depends on the input.
·
For Receivers, if the incoming stream is 204-bytes (because of
Reed-Solomon coding), the output bit-stream also consists of 204-byte
packets (containing 16 bytes of redundant Reed-Solomon error
correction).
·
For Decoders, the output packet length is the same as that at the
input.

Result
This displays the current status of
the incoming Transport Stream.
The Transport Stream Output will
be formatted according to the
choice made.
The Transport Stream Output
(TSO) is now set.
