Seamless 1 mode can use video bit-rates from 0.8 Mbit/s to 10 Mbit/s,

with the actual limits depending on video standard and resolution. This

would be used for 4:2:0 DTH statistical multiplexing applications. The

Encoder delay is approximately 2.5 seconds.
Seamless 2 mode emulates System 3000 6U and 6U+ Encoders. Video

bit-rate can be between 1.5 Mbit/s and 10 Mbit/s. Actual minimum and

maximum rates depend on video standard and resolution.
Seamless 3 mode operates between 5 Mbit/s and 33 Mbit/s, with the

actual limits depending on video standard and resolution. It would usually

be used in 4:2:2 statistical multiplexing applications. The Encoder delay is

approximately 1.1 seconds.
Seamless 4 mode has a very low B

min

. Actual minimum and maximum

depend on the video standard and resolution. This mode would typically be

used for 4:2:0 DTH statistical multiplexing applications.
Seamless 5 mode minimum and maximum depend on the video standard

and resolution.
Seamless 6 mode is typically used with 4:2:2 statistical multiplexing and

a low B

min

. Actual minimum and maximum depend on the video standard

and resolution.

NOTE…
In Seamless Modes 4, 5 and 6 coding performance is compromised a little to achieve lower B

min

s.

Bit-rate Option

To access the Bit-rate option, press the Bit-rate softkey in the Video
Encoder

Menu. An error message is shown with the correct range of

bit-rates if the wrong rate is entered.

NOTE…
High bit-rates in low resolutions cannot always generate sufficient bits to match the requested bit-rate.

However, a valid picture will still be produced.

CAUTION…

When using the Encoder with a PRO IRD M2/PSR/3/422BAS in 4:2:2 mode the upper video bit-rate limit

of the IRD is 25 Mbit/s.

VBR Mode Option

NOTE…
This option is available in Build version 3.0 and later.
