DV-Lab - Wireless Camera COFDM Systems

VideoLink HD

The new generation of VideoLink is intended to be used both with HD and SD video cameras for live reporting of events (news, sports competitions, rallies, concerts, etc). A distinctive feature is using of a new MPEG4/AVC (MPEG-4 Part 10) encoder which allows to transmit HD and SD signals. In SD mode it is possible to transmit 1.5 times more information (with the same picture quality) than when using the MPEG2 transmission . But the main thing is the possibility of transferring HD signal of 1920h1080i format Maximum stream bit rate: up to 12 Mbps. Modulation : QPSK and 16-QAM. Transmitter control has become more obvious and intuitive. All information is displayed on the LCD : channel number, channel frequency, mode (SD or HD) and if SDI or HDMI input is used. An operator can choose one of 8 or 16 preset channels. Each channel can be set to the desired mode and frequency.

VideoLink 800

The VideoLink 800 Wireless Camera COFDM system is intended for digital video/audio transmission in a frequency range of 762-818 MHz from a professional video camera to a TV van.The system provides reliable transmission for up to 70 m indoors and under severe conditions and up to 500 m at open areas.The VideoLink is capable of operation at one of 8 fixed frequencies in 762-818 MHz frequency range. The frequency selection is controlled by buttons placed at the unit panel as well as selection of rate (6 or 10 Мb/s). As a receiver it is used a DVB-T tuner (third party product that isn’t included in standard delivery set). The system provides one channel video and audio transmission. It is possible to complete the system with SDI or DV input option. Fastening element for Sony or Anton Bauer video camera is provided.

VideoLink-2300

The VideoLink-2300 Wireless Camera COFDM system is intended for digital video/audio transmission in a frequency range of 2300 MHz from a professional video camera to a TV van.The system provides reliable transmission for up to 70 m indoors and under severe conditions and up to 500m at open areas.

VideoLink-Simple

The VideoLink-Simple Wireless Camera COFDM system is intended for digital video/audio transmission in a frequency range of 762-818 MHz from a semi-professional video camera or other video/audio source. The system provides reliable transmission for up to 70 m indoors and under severe conditions and up to 500m at open areas.
