Abstract:
Embodiments of the present disclosure relates to a method and a system for switching display from a first video source to a second video source. The system receives a source switch indication request for switching the display from the first video source to the second video source identified by source identification of the second video source. Further the system synchronizes the source switch indication request using frame sync of the first video source and the second video sources and mask the interface signals of the first video source to generate output interface signals corresponding to the second video source. The display is then driven by the output interface signals of the second video source thereby enabling seamless switching of the display without using frame buffer, thereby rendering the video stream from multiple video sources without any tearing artifacts or display glitches and still optimizing the switching latency.

Claim (Index 7):
A video switching processing system for switching display from a first video source to a second video source, system comprising:\n a multilayer synchronization and mask unit (MSMU) and a switching unit coupled with the MSMU, wherein the MSMU is configured to receive one or more interface signals from the first video source and the second video source, wherein one or more interface signals include at least one of frame sync, line sync, clock, data enable and data, wherein the MSMU comprises at least:\n a first delay unit, a second delay unit, and a sync mask unit coupled with the first delay unit and the second delay unit; \n wherein the first delay unit is configured to: \n receive input frame sync of plurality of video sources that comprises at least the first video source and the second video source; \n receive one or more user inputs comprising at least a source switch indication and new source identification (ID) associated with the second video source, wherein the source switch indication comprises a request for switching the display from the first video source to the second video source; and \n synchronize the source switch indication and the new source ID with frame sync of the first video source to generate a first delayed source switch indication and first delayed new source ID; \n wherein the second delay unit is configured to synchronize the first delayed source switch indication and the first delayed new source ID with frame sync of the second video source to generate a second delayed source switch indication and second delayed new source ID; \n wherein the sync mask unit is configured to mask the one or more interface signals of the first video source using the first delayed source switch indication; and \n wherein the switching unit is configured to generate one or more output interface signals for switching the display from the first video source to the second video source based on the second delayed source switch indication and the second delayed new source ID.
