JCN joint communications network (US DoD) ) - Oki Electric announced on January 11 that it has successfully transmitted encoded MPEG-4 video over a satellite phone using its portable video encoder A hardware device or software that assigns a code to represent data. See encode.

1. (algorithm, hardware) encoder - Any program, circuit or algorithm which encodes.

Example usages: "MPEG encoder", "NTSC encoder", "RealAudio encoder".
2. transmitter MPEG-4 Encoder RS-M.

Connected to a camera, the RS-M can transmit encoded MPEG-4 video in realtime. Available on the market since February 2005, the product measures 180x117x105mm, weighs 1.2kg and enables video transmission via IP networks by compressing video in MPEG-4 format.

In an experiment via the INMARSAT satellite communication service, OKI used the RS-M to encode (1) To assign a code to represent data, such as a parts code. Contrast with decode.

(2) To convert from one format or signal to another. See codec and D/A converter.

(3) The term is sometimes erroneously used for "encrypt. video taken with a small digital camcorder in MPEG-4 format and transmit it to a fixed satellite using the INMARSAT M4 satellite phone system, received video at a ground base station and delivered it to a client PC via the Internet.

Oki tested two transmission speeds: 5 fps in QCIF See CIF.

QCIF - Quarter CIF format at 32Kbps and 10 fps in QCIF at 48Kbps. The company confirmed that transmission was completed within 3 seconds at either speed, not much different from ground transmission over the FOMA See i-Mode. cellular network.

Oki expects that the compact and light encoder will be used to transmit IP video via satellite, paving the way for the development of a portable live streaming system.
