Abstract: To allow for greater interactivity in video chat environments, displaying multiple effects from a sender of a first electronic device to a chat client of a second electronic device on a video chat region starts with the sender selecting an effect. If the selected effect has a predetermined mapping interactive effect, the interactive effect is displayed on the chat client. Then, the sender applies the effect or the interactive effect to an application region of the video chat region of the chat client. The application region is a partial or an entire region of the video chat region.

Abstract: A method for weeding out commercials by searching for the existence of key segments at the time the commercials are going to interrupt and resume a main program is provided. The method includes steps of receiving an input source, searching for a program interruption section and a program resumption section in the input source, marking a plurality of key segments in the input source corresponding to the program interruption section and the program resumption section, and finding a plurality of commercials between the key segments. Therefore, similar key segments can be automatically or manually searched so as to filter commercials in the program.
