Patent ID: 8731049

Claim:
An image data transmitting apparatus comprising: an image compression unit configured to compress image data; a marker insertion unit configured to insert a synchronization marker for each of the image data compressed by the image compression unit; and a transmitter configured to transmit the image data into which the synchronization marker has been inserted, using a transmission method for digital audio signals, wherein a bit sequence constituting the synchronization marker is so set as to become a value different from a bit sequence, converging to zero, which is generated by the transmitter or a receiver for receiving the image data transmitted from the transmitter when a mute function is activated in the transmitter or the receiver, the bit sequence constituting the synchronization marker being set within an upper allowable range from an upper limit of a range of digital data compressed by the image compression unit or set within a lower allowable range from a lower limit of the range thereof toward the upper limit of the range thereof.
