Patent attributes
A data packing circuit and a data packing method operated in a high definition multimedia interface (HDMI) transmitter that adopts a fixed rate link mode are provided. The data packing circuit can output a plurality of FRL super blocks at a plurality of unit times. In the data packing method, multiple valid data inputted to the data packing circuit at the (i)th unit time are mapped to a plurality of FRL characters, and the FRL characters are stored to the first or the second buffer. At the same time, an amount of tri-byte of the multiple valid data is counted for determining number and positions for inserting gap characters to form the (i)th FRL super block, which is outputted at the (i+1)th unit time. The numeral ‘i’ is a positive integer.
