Live video sharing method and system and readable storage medium

The invention provides a live video sharing method, which is applied to a digital terminal and comprises the following steps: acquiring a target live program code stream according to a trigger instruction; decoding and forwarding the target live program code stream to a first playing device; slicing the decoded target live program code stream, adding verification data and writing into a built-in database; and forwarding the target live program data in the built-in database to the second playing device through the 5G module. The invention further discloses a system and a storage medium. According to the invention, the live program video stream is distributed through the digital terminal, and the high-resolution original live program code stream data after decoding, frequency locking and slicing of the live program code stream is issued to the third-party playing device through the 5G network while the playing effect of the first playing device is not affected, so the user can obtain real-time live broadcast wa
