Abstract
Systems, methods, and devices perform synchronization operations for video streams. Methods include receiving a video frame at a frame capture unit, the video frame being included in a stream of video data, buffering the video frame using a buffer coupled between the frame capture unit and a frame display unit, and determining an offset value based, at least in part, on a refresh rate associated with the frame capture uni. Methods further include reading, using the frame display unit, the video frame from the buffer after a designated period of time defined by the offset value.
Claims20
A method comprising:
- receiving a video frame at a frame capture unit, the video frame being included in a stream of video data;
- buffering the video frame using a buffer coupled between the frame capture unit and a frame display unit;
- determining an offset value based, at least in part, on a refresh rate associated with the frame capture unit;
- and
- reading, using the frame display unit, the video frame from the buffer after a designated period of time defined by the offset value.
A system comprising:
- a memory device comprising a buffer, the buffer being configured to buffer video data;
- and
- a processing device comprising a frame capture unit and a frame display unit, the processing device configured to:
- receive a video frame at the frame capture unit, the video frame being included in a stream of video data;
- determine an offset value based, at least in part, on a refresh rate associated with the frame capture unit;
- and
- read, using the frame display unit, the video frame from the buffer after a designated period of time defined by the offset value.
A device comprising:
- processing elements configured to:
- receive a video frame at the frame capture unit, the video frame being included in a stream of video data;
- buffer the video frame using a buffer coupled between the frame capture unit and a frame display unit;
- determine an offset value based, at least in part, on a refresh rate associated with the frame capture unit;
- and
- read, using the frame display unit, the video frame from the buffer after a designated period of time defined by the offset value.
