ABSTRACT:
A time code generator is provided and contains a detector, a serial-to-parallel (S/P) converter, a selector, a latch, a line window signal generator, a clock generator, and an interface. The detector detects serial time code information by comparing a composite video information having a digital conversion level with a selected reference level. The S/P converter converts the serial time code information into parallel time code information. The selector selectively outputs the composite video information or the parallel time code information as selected information. The latch latches the selected information as latched information in accordance with a predetermined transmission rate and outputs the latched information as an output signal. Also, the latch latches the selected information in response a time code clock signal. The line window signal generator generates a line window signal by comparing a line count value of the composite video information with preset time code start information and preset time code stop information. The clock generator generates the time code clock signal in response to the line window signal. The interfaces inputs external data and generates control signals which control the detector, the S/P converter, the selector, the latch, the line window signal generator, and the clock generator in accordance with the external data. Based on the above configuration, the time code information can be generated in response to externally supplied data, and thus, the generator is compatible with different types of time code information.
