Abstract
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.
Claims18
A 360-degree virtual reality (VR) video segmentation transmission system comprising:
- a transmitter configured to:
- generate a plurality of frames of a 360-degree VR video comprising a low resolution content and a high resolution content for transmitting the 360-degree VR video through multiple channels based on a motion picture expert group (MPEG) transport stream (TS), the low resolution content comprising a plurality of low resolution content segments, the high resolution content comprising a plurality of high resolution content segments, each of the plurality of frames comprising metadata, one of the plurality of low resolution content segments, one of the plurality of high resolution content segments and a null packet;
- generate a plurality of header packets, process each frame to generate a plurality of frame segments of each frame, and generate a plurality of channel signals, each of which contains one of the plurality of header packets and one of the plurality of frame segments;
- and
- transmit each of the plurality of channel signals of each frame through a corresponding one of the multiple channels;
- and
- a receiver configured to receive the plurality of channel signals from the transmitter transmitted through the multiple channels to combine contents contained in the received channel signals through synchronization, and to output the combined contents.
A 360-degree virtual reality (VR) video segmentation transmission method using a 360-degree VR video segmentation transmission system including a transmitter and a receiver, the method comprising:
- generating, at the transmitter, a plurality of frames of a 360-degree VR video comprising a low resolution content and a high resolution content for transmitting the 360-degree VR video through multiple channels based on a motion picture expert group (MPEG) transport stream (TS), the low resolution content comprising a plurality of low resolution content segments, the high resolution content comprising a plurality of high resolution content segments, each of the plurality of frames comprising metadata, one of the plurality of low resolution content segments, and one of the plurality of high resolution content segments and a null packet;
- generating a plurality of header packets, processing each frame to generate a plurality of frame segments of each frame, and further generating a plurality of channel signals, each of which contains one of the plurality of header packets and one of the plurality of frame segments;
- and
- transmitting each of the plurality of channel signals of each frame to the receiver through a corresponding one of the multiple channels so that the receiver receives and processes the plurality of channel signals to output the 360-degree VR video.
