Oki Electric Succeeds in Satellite Transmission with its Portable Video Compression Transmitter, MPEG-4 Encoder RS-M
Proves practical use viable in marine vessels and mountain areas
Tokyo, Japan, January 11, 2006 --Oki Electric Industry Co., Ltd. (TSE: 6703) today announced it has succeeded in transmitting video through satellite phone connections with its portable video compression transmitter, MPEG-4 Encoder RS-M. This experiment proved that a compact, light weighted encoder can transmit Internet Protocol video via satellite link, enabling a portable live streaming system.
"We conducted the experiment based on locations such as marine vessels and mountain areas, where normal transmission routes including fixed LAN, wireless LAN, FOMA® and PHS are unavailable or, at best, difficult to maintain," said Yasukazu Hontama, President of Broadband Media Company at Oki Electric."With the successful result which confirmed that the RS-M can transmit real-time video using a satellite phone connection, we believe the transmitter can be used in various applications, such as video transmission at disaster sites."
The RS-M, launched in February 2005, is a video compression transmitter that can easily send real-time live video from remote locations by simply connecting to a camcorder. It integrates various functions necessary to transmit video, making possible an IP network based video transmitter with a compact size of 180mm (W) x 117mm (H) x 105mm (D) and weight of 1.2 kg. The system can compress a video image to the MPEG-4, with a maximum bandwidth of 1Mbps, transmitting real-time high definition video via various networks including fixed LAN, wireless LAN, FOMA, and PHS.
Oki conducted the experiment to transmit video via the INMARSAT (*1) satellite communication service as follows:
- Encoded video taken by a small digital camcorder into MPEG-4(*2) via RS-M
- Transmitted compressed video to fixed satellite using the satellite phone system, INMARSAT M4
- Received video at ground base station
- Delivered to client PC via Internet
Following are the type of video and transmission speeds used in various experiments:
- Transmit 5 frame per second with QCIF(*3) with a 32Kbps transmission speed
- Transmit 10 frame per second with QCIF with a 48Kbps transmission speed
Through each experiment, video transmission was accomplished with a delay of 3 seconds or less, which was equivalent to video transmission via a FOMA line on ground. The experiments were conducted with the help of Teikoku Sen-I Co., Ltd., a company handling disaster prevention products. Teikoku Sen-I provided the satellite phone system, INMARSAT M4, used in the experiments.
