Sony Corp announced a new version of the "Location Porter," a professional-use real-time video transmission system.

The Location Porter is a system that uses mobile phone networks and the Internet to transmit high quality video in real time without a mobile unit.

Sony unveiled its first Location Porter, which consists of the audio-visual transceiver "RVT-SD100," in February 2009. The RVT-SD100 can be used for both transmission and reception. It transmits video in real time via a mobile network (NTT Docomo Corp's FOMA service) and the Internet.

The RVT-SD100 approximately measures 143 x 80 x 222mm, and cameramen can send video while hanging it from their shoulders.

Because of its small size, Sony considers that the Location Porter can be used not only for broadcasting but also for many other purposes. For example, the company expects that government offices, police agencies and fire departments will use it to collect information in case of emergency. Also, it can be used for monitoring factories, offices and construction sites as well as for other industrial purposes, Sony said.

The new Location Porter consists of the "RVT-SD200," which was developed by improving the functions of the RVT-SD100, and the "RVT-MR200" multi-channel receiver, which can receive images from up to 12 locations at the same time.

While the first Location Porter is only capable of one-to-one communication, the new system enables to send images from up to 12 transmitters to one receiver at the same time. When a monitor is connected to the multi-channel receiver, it is possible to display images from 12 locations at the same time.
