Fujitsu V01 manual 124

Appendixes

STN and DSTN, and active matrix LCD such as TFT.

LED (Light-Emitting Diode)

The IP-9500/IP-900 series has power LED and alarm LED lamps. The power LED lamp lights in green to indicate that the power is on. The alarm LED lamp lights in red to indicate that an alarm has occurred.

Letter Box

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 black bars at both upper/down parts of the video.

MLD v1 (Multicast Listener Discovery version 1)

A protocol that has been defined by RFC2710. It is used to detect a multicast listener that receives a multicast datagram.

MLD v2 (Multicast Listener Discovery version 2)

A protocol that has been defined by RFC3810. In addition to the MLD v1 supporting function, it has an information source filtering function, which enables the specification for receiving only the packets sent from specific origination addresses (or addresses that are not specific origination addresses).

MPEG-4

Video data compression method that is a part of the MPEG standard. MPEG-4 was designed to distribute video images of low picture quality (due to a high compression ratio) over slow communication lines (e.g., cellular phone and telephone lines.) MPEG-4 was also designed to transmit video together with audio at about 64 kilobits per second.

NTSC (National Television Standards Committee)

The standard for analog television systems established by a US standardization body.

IP-900 Series

NTSC images are made of 29.97 interlaced frames per second, each of which is composed of 525 scan lines in total.

Original network ID

ID for identifying a transport stream. Each transport stream is identified by the combination of an original network ID and a transport stream ID.

PAL (Phase Alternating Line)

The standard for analog color television broadcasting developed in Germany. PAL images are made of 25 interlaced frames per second, each of which is composed of 625 scan lines in total.

PAT (Program Association Table)

Table included TS (Transport Stream) and the list in PMT PID. The PID of PMT is 0.

PES (Packetized Elementary Stream)

A packetized method provided by MPEG2 System. Encoded video or audio bit streams are called “Elementary Stream.” These streams are packetized by standard and are called “PES.”

PID

A packet identifier which has the 13 bits information, included in TS packet.

Pilot Mode

A mode adopted in the DVB-S2 standard to improve synchronization characteristics at a low C/N ratio. This device has a setting for specifying whether to insert the pilot signal for synchronized playback into physical layer frames.

Ping

A command supported by operating systems such as UNIX and Windows that are used in a TCP/IP network to determine whether IP packets can reach or have reached a communication destination.
