Method, apparatus, and system for implementing video stream switching

A transmission device, comprising:

• a memory, configured to store computer program instructions;
• and
• a processor, configured to read and execute the computer program instructions, to cause the transmission device to perform the steps of:
• receiving a first video stream and a second video stream;
• sending the first video stream through a target egress port of the transmission device;
• and receiving a switching instruction, wherein the switching instruction is used to instruct to switch from the first video stream sent through the target egress port to the second video stream;
• obtaining the switching reference information of a first switching packet of the first video stream and the switching reference information of a second switching packet of the second video stream;
• and
• switching from the first video stream sent through the target egress port to the second video stream based on the switching reference information of the first switching packet and the switching reference information of the second switching packet.

A system for implementing video stream switching, wherein the system comprises at least one processor and memory storing instructions that when executed by the at least one processor cause the system to:

• receive a first video stream and a second video stream;
• send the first video stream through a target egress port of the transmission device;
• and receive a switching instruction, wherein the switching instruction is used to instruct to switch from the first video stream sent through the target egress port to the second video stream;
• obtain the switching reference information of a first switching packet of the first video stream and the switching reference information of a second switching packet of the second video stream;
• and
• switch from the first video stream sent through the target egress port to the second video stream based on the switching reference information of the first switching packet and the switching reference information of the second switching packet.
