## Abstract

A multimedia playing application control method and a terminal. A terminal receives physical indication information, where the physical indication information is used to control a multimedia playing application running in the terminal. The terminal converts the physical indication information into corresponding control indication information according to a preset correspondence. The terminal sends the control indication information to the multimedia playing application running in the terminal, where the control indication information is used to instruct the multimedia playing application to execute an operation corresponding to the control indication information.

## Claims

### Claim 1

A multimedia playing application control method, comprising:
receiving, by a terminal, physical indication information, wherein the physical indication information is used to control a multimedia playing application running in the terminal;
converting, by the terminal, the physical indication information into corresponding control indication information according to a preset correspondence; and
sending, by the terminal, the control indication information to the multimedia playing application running in the terminal, wherein the control indication information is used to instruct the multimedia playing application to execute an operation corresponding to the control indication information;
wherein sending, by the terminal, the control indication information to the multimedia playing application running in the terminal comprises:
determining, by the terminal, a multimedia playing application to be controlled by the physical indication information,
acquiring, by the terminal, a preset identifier corresponding to the to-be-controlled multimedia playing application, and
broadcasting, by the terminal, a control message carrying the preset identifier and the control indication information, so that the to-be-controlled multimedia playing application receives and executes the control indication information; and
wherein before acquiring, by the terminal, a preset identifier corresponding to the to-be-controlled multimedia playing application, the method further comprises:
sending, by the terminal, a query message to all multimedia playing applications installed in the terminal, wherein the query message is used to query for a preset value corresponding to each multimedia playing application,
receiving, by the terminal, the corresponding preset values that are separately returned by all the multimedia playing applications according to the query message,
using, by the terminal, the preset values as preset identifiers, or generating, by the terminal, preset identifiers according to the preset values, and
storing, by the terminal, the preset identifiers corresponding to the multimedia playing applications.

### Claim 2 (depends on 1)

The method according to claim 1, wherein acquiring, by the terminal, a preset identifier corresponding to the to-be-controlled multimedia playing application comprises:
acquiring, by the terminal, the preset identifier corresponding to the to-be-controlled multimedia playing application from the stored preset identifiers corresponding to the multimedia playing applications.

### Claim 3 (depends on 1)

The method according to claim 1, wherein:
the preset values are package names of the multimedia playing applications; and
generating, by the terminal, preset identifiers according to the preset values comprises:
using, by the terminal, the package names of the multimedia playing applications and a preset character string as the preset identifiers.
