Abstract: A projector includes a lens, a first base, a lock member, a second base and a first fixing member. The lens includes at least one adjusting member. The first base is disposed with respect to the lens. The lock member is disposed on the at least one adjusting member. The second base is disposed with respect to the lock member. When the first fixing member fixes the second base to the first base, the second base pushes the lock member, such that the lock member forces the at least one adjusting member on the lens tightly.

Abstract: A video streaming transmission system and a transmitter device are provided. The video streaming transmission system includes a receiver device and a transmitter device. The receiver device is coupled to a display module. The transmitter device is coupled to an image providing device through a transmission line. The transmitter device includes a processing unit, a storage unit, and a wireless communication module. The storage unit is coupled to the processing unit. The wireless communication module is coupled to the processing unit, and is coupled to the receiver device in a wireless communication manner. The processing unit generates virtual extended display identification data and stores them in the storage unit, and provides the virtual extended display identification data to the image providing device through the transmission line, so that the image providing device recognizes multiple virtual displays coupled thereto, and outputs multiple video streams through the transmission line.

Abstract: A video conference system including a first transmitter device and a receiver device is provided. The first transmitter device transmits a first video data. The receiver device includes a receiver control unit configured to assign a first identification code to the first transmitter device. The receiver control unit combines the first video data and a first identification image corresponding to the first identification code as a first combined video data and the receiver control unit outputs the first combined video data to the display device. Through the present invention, the conference participants can quickly identify which presenter is providing the video signal source corresponding to a particular frame on the split screen, and can raise questions to the right person.
