Glossary and Index

TS (Transport Stream)

The stream used in the multi-programs multiplexing, standardized in MPEG-2 systems. The transport stream offers features for error correction for transportation over unreliable media, and is used in broadcast applications and ATM telecommunication.

TTL (Time To Live)

Abbreviation of time to live, which indicates the survival time of a packet in a network. If a packet sent to a network happens to enter a loop because of a setting error on a router, it will not survive forever but will be discarded when the time specified in the Time To Live field of the IP header is reached.

UDP (User Datagram Protocol)

Abbreviation of User Datagram Protocol, which is a TCP/IP transaction protocol used for specific applications such as remote network management and naming service access

Unicast

Communication with a station at a single address (i.e., most general one-to-one communication)

UTP Cable

Abbreviation of unshielded twisted pair. It is a unshielded pair of wires twisted together, and these wires are used for Ethernet cabling and other purposes.

VFD

Vacuum Fluorescent Display. Because VFD emits by itself, the contrast is clear rather than LCD. Wide temperature range for operation makes less influence to functions.

10BASE-T

LAN that uses unshielded twisted-pair (UTP) cables and complies with the IEEE 802.3 standard. A 10BASE-T connection uses a concentrator called a hub. It is widely used because special cabling work is not necessary and wiring can be done easily. The maximum length of cable wiring is 100 m.

100BASE-TX

One of the 100BASE LAN standards (also called Fast Ethernet), it supports a transfer rate of 100 Mbps. Other 100BASE standards are 10BASE-T4 and 100BASE-FX, and the difference is the type of cable used. 100BASE-TX uses unshielded twisted-pair (UTP) cables. It also uses the RJ-45 connector, which is similar to the modular jacks used for telephones.

1000BASE-T

One of the Gigabit Ethernet standards. It standardized as IEEE802.3ab in 1999, uses the UTP cables of the category 5 (CAT5) and the enhanced category (CAT5e). The maximum transmission distance is 100m and it supports the topology of the hubbing, star and so on.

3G-SDI

A family of interfaces used in the high-definition video transmission required for 1080p and digital cinema.With a transmission capacity as high as 3 Gbps, 3G-SDI enables transmission of 1080/ 60p signals through a single BNC cable.
