Abstract
A method implemented on a computing device including at least one processor and a storage for synchronizing video transmission with physical layer. The method includes determining a first time point corresponding to a frame header of a video frame, determining a second time point corresponding to a frame header of a physical layer frame based at least in part on the first time point, and starting transmitting the video frame at the second time point.
Claims12
A method implemented on a computing device including at least one processor and a storage for synchronizing video transmission with physical layer, the method comprising:
- determining a first time point corresponding to a frame header of a video frame, the video frame including a plurality of sub-frames;
- determining a time period for compressing a sub-frame of the plurality of sub-frames according to a length of the sub-frame and a compression algorithm used for compression the sub-frame;
- determining a second time point based on the first time point and the time period for compressing the sub-frame;
- adjusting a third time point corresponding to a frame header of a physical layer frame to synchronize the third time point with the second time point;
- and
- starting transmitting the sub-frame at the second time point.
A system for synchronizing video transmission with physical layer, the system comprising:
- a memory that stores one or more computer-executable instructions;
- and
- one or more processors configured to communicate with the memory, wherein when executing the one or more computer-executable instructions, the one or more processors are directed to:
- determine a first time point corresponding to a frame header of a video frame, the video frame including a plurality of sub-frames;
- determine a time period for compressing a sub-frame of the plurality of sub-frames according to a length of the sub-frame and a compression algorithm used for compression the sub-frame;
- determine a second time point based on the first time point and the time period for compressing the sub-frame;
- adjust a third time point corresponding to a frame header of a physical layer frame to synchronize the third time point with the second time point;
- and
- start transmitting the sub-frame at the second time point.
A non-transitory computer readable medium including executable instructions that, when executed by at least one processor, cause the at least one processor to effectuate a method comprising:
- determining a first time point corresponding to a frame header of a video frame, the video frame including a plurality of sub-frames;
- determining a time period for compressing a sub-frame of the plurality of sub-frames according to a length of the sub-frame and a compression algorithm used for compression the sub-frame;
- determining a second time point based on the first time point and the time period for compressing the sub-frame;
- adjusting a third time point corresponding to a frame header of a physical layer frame to synchronize the third time point with the second time point;
- and
- starting transmitting the sub-frame at the second time point.
