Injecting a code into video data without or with limited human perception by flashing the code

摘要

A playlist and a digital advertisement are received. The digital advertisement is output to a screen on the basis of information in the playlist. A code is generated based on the information in the playlist and the generated code is output to the screen. The generated code is output to the screen by flashing the generated code on the screen at a predetermined flash frequency and for a predetermined flash time so that the generated code is visually imperceptible or barely detectable to a human viewer. A suitable equipped electronic device may detect the code and utilize information encoded in the code in various ways.

主权项

1. A computer-implemented method for injecting a code into video data without or with limited human perception, the method comprising performing computer-implemented operations for:
receiving a playlist and a digital advertisement from a server; outputting the digital advertisement to a display screen using the playlist; generating a code containing information; and outputting the generated code to the display screen by flashing the generated code on the display screen during the outputting of the digital advertisement at a predetermined flash frequency and for a predetermined flash time so that the generated code is visually imperceptible or barely detectable to a human viewer, and
whereby a client device can capture the digital advertisement, decode the information in the generated code, and provide the information to the server, andwhereby the server can utilize the information received from the client device to determine an effectiveness of the digital advertisement at the display screen.
