3.3.3.2 EMA 407 Transcoder, H.264/ AVC to MPEG-2

Example: A H.264/ AVC service from the ASI input signal is transcoded to MPEG-2 SD.

Maximum 2 per unit, services can be implemented in this mode.

ASI input is 

activated.

Encoder in slot A

is set to decoder

ASI main input is active

and is provided to the 

encoders as 

internal signal source.

The H.264/ AVC HD

service (SID 45) is

passed in the mode 

decoder through the

 internal output to the

 MPEG-2 encoder. 

The signal from internal

input is encoded to a

MPEG-2 service. 

Input signal of the 

encoder A is set to 

“Intern TS“.
