IP-900 Series
121
CF Card
A memory card of CompactFlash that is used
as storage for recorded data in the IP-9500
series/IP-900 series products.
Chroma Format
Representation of the ratio of the brightness
component (Y) and 2 color-difference
components (Pb and Pr) expressed for an
image. The 2 formats generally used are 4:2:2
and 4:2:0.
CSC4:2:2 (4:2:2 Chroma Scalable Coding)
4:2:2 encoding system unique to the IP-9500
series. In this system, the encoder applies
bandwidth splitting to the color-difference signal
of an input 4:2:2 video stream and generates
two video streams: a 4:2:0 video stream and a
0:0:2 video stream. The 4:2:0 video stream
includes a brightness signal and low-frequency
color-difference signal. The 0:0:2 video stream
includes only a high-frequency color-difference
signal. Then, the encoder encodes two video
streams. The IP-9500e decoder decodes these
two video streams and combines the
low-frequency and high-frequency
color-difference signals to output the 4:2:2 video
stream. Since a conventional 4:2:0 decoder can
decode and output the 4:2:0 stream included in
a CSC422 stream, the CSC422 encoding
system achieves scalability between 4:2:2 video
and 4:2:0 video.
Downconverter
Converting from HD-SDI signal to SD-SDI
signal. 3 modes are available: Squeeze, Side
cropped, and Letter box.
DVB-ASI (Digital Video Broadcasting
- Asynchronous Serial Interface)
Standard interface in DVB (Digital Video
Broadcasting: European Digital Broadcasting
standardization organization) and used in
MPEG CODEC most commonly. It is the
asynchronous serial interface and standardized
in ETSI 101 891.
DVB-S (Digital Video Broadcasting
-
Satellite)
Standard interface for satellite broadcasting
formulated by the DVB (European
standardization body for digital broadcasting.)
DVB-S2 (Digital Video Broadcasting
-
Satellite - Second Generation)
Successor standard to DVB-S. DVB-S2 adopts
more efficient error correction encoding and
multi-value modulation with 16 values or more,
ensuring an increased transmission capacity. It
supports various data formats in addition to
MPEG-2 TS. This enables flexible operation
because the modulation method, encoding rate,
and roll-off rate can be changed.
Embedded Audio
A method to embed AES/EBU digital audio
signal into the blank area of SDI (Serial Digital
Interface) signal.
Encrypted Session Word
16-character (64-bit) word specified by the user
in BISS MODE E. A session word is derived
from the specified encrypted session word (and
injected ID.) Then, encryption or decryption in
BISS MODE E is performed.
Ethernet
The protocol that has been standardized by the
IEEE 802.3 Committee, defining the physical
and link layers of a LAN. Typical Ethernet
connections use twisted pair cables, such as
10BASE-T or 100BASE-TX, and switching
hubs.
Factory Shipment Firmware
Firmware that is installed at a factory before
shipping and has the minimum function like the
installer, and so on.
FEC (Forward Error Correction)
A method that the sender transmits redundant
packet to the receiver for error correction in
addition to the sending packet. It enables the
