A 360-degree virtual reality (VR) video segmentation transmission system and a method are disclosed. The system includes a transmitter and a receiver. The transmitter designs a frame for transmitting a 360-degree VR video divided into multiple channels, based on a motion picture expert group (MPEG) transport stream (TS), and transmits a signal combining the designed frame and a header for each of the multiple channels. The receiver receives the signal from the transmitter for each channel, combines contents contained in the received signal through synchronization, and outputs the combined contents.

360-degree VR video segmentation transmission system and method

The present invention relates to sound data transmission between a wireless sound transmitter that transmits sound data received from a multimedia source, and a wireless sound speaker that outputs sound signal by receiving the sound data, and more particularly, to a method for compensation of a play time delay between the wireless sound speakers occurring when the multichannel sound data is distributed and transmitted from the wireless sound transmitter to the multiple wireless sound speakers. The differences in the play time points occurring between the speakers in a TDMA based multichannel wireless transmission system, are pre-compensated through the delay of the sound data in the WSDT.
