Seamless 1 mode can use video bit-rates from 0.8 Mbit/s to 10 Mbit/s,
with the actual limits de pending on video standard and resolution. This
would be used for 4: 2:0 DTH statistical mu ltiplexing 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 stat istical multiplexing applic ations. The Encode r delay is
approximately 1.1 seconds.
Seamless 4 mode has a very low Bmin. 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 multiplex ing and
a low Bmin. 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 Bmins.
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.
