Instruction Manual: evolution 5000 E5710 and E5720 Encoder
ST.TM.E10074.1
The audio functionality supports multiple sampling frequencies, bit-rates
and coding modes. Audio can be input in balanced analogue, digital
AES/EBU input as a discrete channel or embedded on serial digital video.
Additional audio channels can be accommodated by using the appropriate
option (see Chapter 3, Options and Upgrades).
Control of the unit is via an Ethernet connection to the evolution 5000
Multiplex Element Manager (MEM) (see Section 1.3.5, Control and
Monitoring for more ways to control the unit) or via local control using the
front panel keyboard. Local health monitoring is incorporated, as is
automatic redundancy switching and a local alarm/fail/reset port.
The output of the unit is a multiplexed transport stream in DVB ASI
format. Three ASI outputs are provided; two to ensure that redundancy of
multiplexing equipment can be supported, one as a spare output for
monitoring purposes.
Unit functionality can be further extended with option modules (see
Chapter 3, Options and Upgrades).
1.2.2
Single Programme Transport Stream
If the SPTS mode is used, the multiplexed video, audio and data signals
are output in an SPTS MPEG-2 transport stream format for direct
connection to a Modulator (see Figure 1.5). A direct connection is provided
for a control computer.

For further information on the evolution 5000 range of products, refer to
the appropriate manual or contact Customer Services (see Preliminary
Pages).
1.2.3
Multiple Channels Per Carrier
If the Multiple Channels Per Carrier (MCPC) mode is used, the multiplexed
video, audio and data signals are output in an MCPC MPEG-2 transport
stream format for direct connection to a Multiplexer (see Figure 1.6). A
direct connection is provided for a control computer.
