Product Description
  R760, as one neo-type HD wireless video transmission Rx module, can receive the HD wireless live video and audio signals sent by MV2000, MV2025 and MV2500 series transmitters. It is propitious to mobile video transmission in NLOS condition and high-speed movement due to its small size, low consumption and high receiving sensitivity. Its mater chip adopts COFDM demodulation, embedded system and MPEG-2/H.264 video cramping and de/encoding based on HD standard for high stability, good extensibility and benign transmission.
   R760 has diversity of interfaces: one CVBS, one HDMI, one USB, one RJ45, two analog audio outputs and two 233 serial ports. One more CVBS extended is available if required and two IR interfaces reserved for remote control. Extension of all the interfaces on the module is possible though MINI PCI in line with its physical criterion.
