Abstract:
1. A linear time code (LTC) generator that is adapted to generate LTC data, the LTC generator comprising: a detector that is adapted to detect a frame sync input corresponding to a beginning of a frame time of video data and to generate a first synchronization signal corresponding to the frame sync input; a frame length determination block that is adapted to determine a frame length of the video data in clock cycles by counting a number of clock cycles in the frame time; a bit rate counter block that is adapted to generate a second synchronization signal corresponding to a bit rate that is determined from the frame length in clock cycles; and an output device that is adapted to insert a first data bit of the LTC data into a digital bit stream according to the first synchronization signal and to insert subsequent data bits of the LTC data into the digital bit stream according to the second synchronization signal, so that the application of the LTC data is not dependent on the frame length, wherein said bit rate being determined according to the formula where x is twice a length of a time code information word of the linear time code data and n is a number of time code information bits.
