SEAMLESS VIDEO SWITCHING METHOD AND SYSTEM IN VIDEO MATRIX

A method and seamless video switching method and system in video matrix. The method includes dividing a memory address on a memory for storing video data into several memory spaces; and reading and writing the video data normally under the condition that no video switching instruction is received; or executing steps as follows: enabling, during a period when the video switching instruction keeps valid, a write control module to skip back to a head address of a memory space currently written to write a frame of image in video data of a target channel after switching into the current memory space; and enabling a read control module to skip back to a head address of a memory space currently read to read a frame of image from the current memory space until the video switching instruction is invalid.
