The testing cases are generated by fuzzing testing methods according to the HDLC specifications. The CTT 3.1 is used as the client sending requests to the smart meter server.

The continuous development of the media has drawn it closer to sports, and television broadcasting is an important facilitator in making sports events widely popular among people.The sports of table tennis require the use of a small court and a small ball played in a fast speed with strong rotation and variable landing points. These characteristics also lead to some limitations, which may greatly reduce audiences’ sense of immersion, experience and participation in events; and the screen design of television broadcast becomes very important.
