Display apparatus, light receiving apparatus, communication system, and communication method
First Claim
1. A communication method performed between a display apparatus having a display screen capable of displaying moving pictures and a light receiving apparatus having a light receiving means capable of receiving light by using a two-dimensional dynamic code which is a two-dimensional code changing along a time axis, the communication method comprising the steps of:
- configuring the two-dimensional dynamic code so as to include a plurality of symbols, the symbols including a data symbol which is a two-dimensional code expressed with a format for data transmission, and an anchor symbol which is a two-dimensional code expressed with a format for anchor transmission; and
displaying the data symbol on the display screen in the display apparatus, along the time axis, while displaying the anchor symbol on the display screen every time the data symbol is displayed once or a plurality of times.
