Abstract

A method for content projection and a mobile terminal are provided. The method includes that a mobile terminal runs a local playing service, a content projection control service and at least two protocol projection control services. A first projection instruction is acquired through the content projection control service, a first content played by the local playing service is intercepted, and the intercepted first content is transmitted to first protocol projection control service. The first content is transmitted to a first projection service through the first protocol projection control service by virtue of a first projection protocol.

First claim

What is claimed is:

1. A method for content projection, comprising:
running, by a mobile terminal, a local playing service, a content projection control service and at least two protocol projection control services, wherein different protocol projection control service supports different projection protocols;
acquiring a first projection instruction through the content projection control service, intercepting a first content played by the local playing service, and transmitting the intercepted first content to a first protocol projection control service, wherein the first protocol projection control service is a protocol projection control service, among the at least two protocol projection control services, which detects a first projection service issued by playing equipment; and
transmitting the first content to the first projection service through the first protocol projection control service by virtue of a first projection protocol, the first content being configured for the first projection service to play on a corresponding playing equipment, wherein the first protocol projection control service and the first projection service both support the first projection protocol,
wherein a number of the protocol projection control services run by the mobile terminal is determined according to a number of projection protocols to be supported.

2. The method according to claim 1 , further comprising:
when the first content is transmitted through the first protocol projection control service to the playing equipment issuing the first projection service, if a second playing instruction of indicating a second content to be played is acquired through the local playing service, playing the second content on a display interface of the mobile terminal through the local playing service, and maintaining the first projection service for the first content through the first protocol projection control service, the second content being different from the first content.

3. The method according to claim 1 , further comprising:
when the first content is transmitted to the first projection service through the first protocol projection control service, acquiring through the content projection control service an instruction of switching the first protocol projection control service to a background; and
executing through the first protocol projection control service an operation of switching to the background, and maintaining the first projection service for the first content.

4. The method according to claim 1 , wherein transmitting the first content to the first projection service through the first protocol projection control service by virtue of the first projection protocol comprises:
causing the first projection service to try to play the first content in different formats on the corresponding playing equipment through the first protocol projection control service until the first projection service successfully plays the first content in a certain format on the corresponding playing equipment.

5. The method according to claim 1 , further comprising:
displaying a status control interface on a display interface of the mobile terminal through the content projection control service, wherein a status of the first projection service for the first content is displayed on the status control interface; and
acquiring a status control instruction for the first projection service for the first content through the content projection control service, and transmitting the status control instruction to the first protocol projection control service to cause the first protocol projection control service to regulate the status of the first projection service.

6. The method according to claim 1 , further comprising:
displaying a candidate projection service on a display interface of the mobile terminal through the content projection control service, the candidate projection service being at least one projection service issued by the playing equipment and detected by the at least two protocol projection control services;
acquiring through the content projection control service an instruction of switching a projection service used for the first content, and determining a second projection service to be switched for the first content; and
transmitting through a second protocol projection control service the first content to playing equipment issuing the second projection service, the first content being configured for the second projection service to play on a corresponding playing equipment, wherein the second protocol projection control service is a protocol projection control service, among the at least two protocol projection control services, which detects the second projection service, and the second protocol projection control service and the second projection service both support a second projection protocol.

7. The method according to claim 1 , further comprising:
displaying a candidate projection protocol on a display interface of the mobile terminal through the content projection control service, the candidate projection protocol being a projection protocol supported by a projection service detected by the at least two protocol projection control services;
acquiring through the content projection control service an instruction of switching a projection protocol used for the first content, and determining a new projection protocol for the first content; and
transmitting the first content to a new projection service through a third protocol projection control service to cause the new projection service to play the first content on a corresponding playing equipment, the third protocol projection control service being a protocol projection control service using the new projection protocol.

8. The method according to claim 2 , wherein a playing progress of the first content played by the local playing service is transmitted to the first projection service through the content projection control service, and the first projection service plays the first content on the playing equipment according to the playing progress of the first content.

9. The method according to claim 3 , wherein if second content is played on a display interface of the mobile terminal and after the first protocol projection control service is switched to the background, then the second content is continued to be played in a non-full screen window on the display interface of the mobile terminal.

10. The method according to claim 4 , wherein the first projection service tries to play the first content in one format on the corresponding playing equipment for multiple times before success; when a maximum try count is reached, the first projection service tries to play the first content in another format on the corresponding playing equipment.

11. The method according to claim 6 , wherein the mobile terminal stores, through the content projection control service, progress information of the first content played by the first projection service and transmit the progress information to the second projection service.

12. A mobile terminal, comprising:
a processor; and
a memory storing instructions that, when executed by the processor, cause the processor to:
run a local playing service, a content projection control service and at least two protocol projection control services, wherein different protocol projection control service supports different projection protocols;
acquire a first projection instruction through the content projection control service, intercept a first content played by the local playing service, and transmit the intercepted first content to a first protocol projection control service, wherein the first protocol projecti
