High-definition blue-ray recording and playing system

The utility model discloses a high-definition blue-ray recording and playing system. The high-definition blue-ray recording and broadcasting system includes an interface module; a recording module connected with tape recording data through the interface and connected with optical data disk data; a call output module connected with the optical data disk data and outputting through the interface module; a palyback module connected with the optical data disk data and outputting through the interface module; a control module connected with the recording module, the call output module and the playback module. The high-definition blue-ray recording and broadcasting system can record SDI video signals on a commonly-used blue ray disc with long service lifetime and high performance cost directly, and can be used for playing the blue-ray disc with recorded data directly and output the signals to other devices through an SDI interface.
