Introduction

1.3.6 Table Processing

The SPR1100 generates the following tables:

 PAT (Program Association Table).

 PMT (Program Map Table).

 SDT (Service Descriptor Table).

 CAT (Conditional Access Table).

The SPR1100 will not pass through or process any other tables and these, including

the following, will be dropped:

 EIT (Event Information Table).

 NIT (Network Information Table).

 SDT (Service Description Table).

1.3.6.1 Multiple PMTs in a PID

The SPR11

00 can support incoming MPTSs where the PMTs for the services are in

one PID.

1.3.7 Transport Streams

1.3.7.1 Unicast Input

An incoming unicast is detected by its IP address. If the IP address is outside the

reserved multicast address range, it is treated as a unicast.

1.3.8 Redundancy

The SPR1100 supports the following redundancy modes:

 Input source redundancy.

 Input port redundancy:

- Active active 1+1 redundant pair or

- 2 inputs adding together i.e. each receiving different streams.

 Output Port redundancy:

- Active standby only.

- No active active yet.

 Chassis redundancy:

- 1+1 active standby.
