PROGRAM SWITCHING METHOD, DEVICE, TELEVISION SET, AND READABLE STORAGE MEDIUM

The present application discloses a program switching method, a device, a television set, and a readable storage medium. The method comprises: upon receiving a program switching instruction, requesting, according to a target program identifier in the program switching instruction, to obtain a program description information USD table, corresponding to a target program, as a target USD table, and acquiring a target program content identifier of the target program from the target USD table; determining whether a pre-determined mapping table has a target resource package identifier corresponding to the target program content identifier; and if so, acquiring and playing corresponding target program data according to the target resource package identifier, so as to switch a current program to the target program. The present application reduces the time required to switch programs by using the pre-determined mapping table, and increases a program switching speed, thereby improving the user experience, and solving t
