Using the Equipment
The RX8200 Advanced Modular Receiver is capable of performing simultaneous
down-conversion from HD to SD. This functionality means that the IRD can decode
the native HD video and output the on HD interfaces (HD-SDI and RGB/YPrPb), and
at the same time perform down-conversion on the decoded HD video and generate
an SD version for output on the SD interfaces (SD-SDI and CVBS).
The HD video and down-converted SD video are output simultaneously. Because
the HD and SD video are synchronized, audio lip sync is maintained on both HD and
SD video.
Figure 3.100 Down-conversion Quality Levels
The RX8000 Advanced Modular Receiver offers different levels of down-conversion
quality, where the Grade levels are defined by Ericsson:
•
•
•
Note: The RX8305 does not have HD decode capability so therefore does not
3-212
Grade 1 Down-conversion – High quality down-conversion option
(RX8200/HWO/HQDCONV) which requires a dedicated hardware option to be
present within the RX8200. This implies that the outgoing, down-converted SD
video is of the highest possible quality and eminently suitable for broadcast.
Grade 2 Down-conversion – Quality down-conversion option
(RX8200/SWO/DCONV) which can be enabled on every RX8200 via a
chargeable software license key. This video quality level is definitely suitable for
high quality monitoring applications and may be considered suitable for
broadcast by some operators, particularly if the incoming native HD content is in
720p format.
Grade 3 Down-conversion – Available on the RX8300 series IRDs, it offers
grade 3 quality down-conversion. This video quality is equivalent to consumer
set-to-box down-conversion quality. This level of quality is still considered
suitable for broadcast by many operators and broadcasters.
