Appendixes
IP-900 Series
126
RS-232C
Interface standard that was mainly established
by the Electronics Industry Association (EIA) for
communication between data terminal and data
communications equipment.
RTP
Abbreviation of real-time transport protocol.
This transport protocol is for transferring the
image data or the voice data in real time.
SD-SDI (Standard Definition television
- Serial Digital Interface)
Standard definition digital video interface
standardized in SMPTE259M.
Session Word
12-character (48-bit) word specified by the user
in BISS MODE 1. The specified session word is
used for encryption or decryption in BISS MODE
1.
Side Cropped
One of the methods to downconvert video
sourse of screen size ratio (aspect ratio) from
16:9 to 4:3 screen size. The resulting image has
both left and right sides cropped.
SNMP v1 (Simple Network Management
Protocol version 1)
Communication protocol defined by RFC1065,
RFC1066, and RFC1213 for monitoring and
controlling network devices. The protocol
defines a framework for network management
protocols and other protocols. This framework is
used for SNMP v2c, SNMP v3, etc.
SNMP v2c (Simple Network Management
Protocol version 2c)
Communication protocol defined by RFC1901
and RFC1908 for monitoring and controlling
network devices. The protocol enables
communications using v2, which has higher
communication security and performance, on a
community basis similar to communications
using v1.
Spectrum
Specified spectrum sense for the IP-9500
series can be "Normal" or "Inverted." Select the
setting according to local configuration of your
wireless devices and transponders.
Symbol Rate
Symbol transmission speed defined by the
number of symbols sent to the transmission line
per second. The unit of measurement is
symbol/s.
System rate
Data amount per second of the encoding data
including up to MPEG2 system. The data for the
network packet or FEC packet is not included.
Subnet Mask
Mask value that is used to obtain the network
address of a subnet from an IP address. The
subnet address is obtained when the IP address
is ANDed with the subnet mask.
TCP (Transmission Control Protocol)
Abbreviation of Transmission Control Protocol,
the protocol required for direct connection to the
Internet. In the OSI reference model, TCP
corresponds to the transport layer and IP
corresponds to the network layer. TCP has been
a global standard protocol that is supported by
major operating systems, including UNIX, OS/2,
and Windows.
TOS (Type Of Service)
Type of service that can be added within IP
packets. It is used for controlling the order of
priority of packets in the router etc.
Tri-sync
Sync signal used for High Definition TV. There
is a feature of not generating the phase gap
even if sync signal shrinks by the signal
attenuation.
TS (Transport Stream)
Abbreviation of Transport Stream, which is an
MPEG-2 systems for multiplexing video, audio,
and data. A stream consists of packets, each of
