Embodiment 1

[0044] 201. Through the user interface layer, the CMMB terminal receives the user's operation request, and the user interface layer sends the user's first operation request to the control layer. The user's first operation request may specifically include: system settings, hardware retrieval, channel switching, channel Scan and record programs, etc.;

[0045] 202. The control layer determines whether the first operation request is a first-type operation request or a second-type operation request according to a business rule.

[0046] If the first operation request is a first-type operation request, proceed to step 203, otherwise proceed to step 204;

[0047] Wherein, the type of the operation request can be divided according to whether the specific content of the first operation request needs to be executed by the driver layer, then: the business rule can include:

[0048] If the first operation request is a system setting, the first operation request is a first type of operat...

Embodiment 2

[0114] In the following, two specific operation requests are taken as examples to illustrate the processing procedure of the present invention. Such as image 3 Shown is the flowchart of Embodiment 2 of the present invention, including:

[0115] 301. The user searches for channel information through the user interface layer; the user interface layer is responsible for interacting with the user, so the user interface layer receives user operation requests by providing the user with methods such as clicking buttons and selecting menus,

[0116] 302. After the user selects the "search channel" operation, the user interface layer sends an operation request to the control layer. After receiving the operation request, the control layer analyzes it and learns that "search channel" needs thread execution, so it will start the channel thread to perform the following deal with:

[0117] 303. Determine whether the preconditions required for the execution of the "search channel" are sat...

Embodiment 3

[0131] Such as Figure 4 As shown, it is a block diagram of the device for playing mobile multimedia provided by the embodiment of the present invention. This embodiment has the same three-layer architecture as the method embodiment, including:

[0132] The first sending unit 401 is configured to send the user's first operation request from the user interface layer to the control layer;

[0133] The first judging unit 402 is used for the control layer to judge whether the first operation request is a first type operation request or a second type operation request according to business rules;

[0134] A first execution unit 403, located in the control layer, configured to execute the first operation request if the first operation request is a first type operation request;

[0135] The second execution unit 404, located in the driver layer, is configured to execute the first operation request if the first operation request is a second type operation request.

[0136] Wherein, ...

Abstract

The embodiment of the invention discloses a device for playing mobile multimedia, which comprises a first sending unit, a first judging unit, a first execution unit and a second execution unit, wherein the first sending unit is used for sending a first operation request of a user from a user interface layer to a control layer; the first judging unit is used for the control layer to judge whether the first operation request belongs to a first kind of operation requests or a second kind of operation requests according to business rules; the first execution unit is positioned in the control layer and is used for executing the first operation request if the first operation request belongs to the first kind of operation requests; and the second execution unit is positioned in a driving layer and is used for executing the first operation request if the first operation request belongs to the second kind of operation requests. The embodiment of the invention obviously improves the expandability, the stability and a large number of concurrency controls of a system and can more properly solve the problems caused by multiple concurrent operations of users.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and device for playing mobile multimedia. Background technique [0002] CMMB (China Mobile Multimedia Broadcast, China Mobile Multimedia Broadcast) is a mobile multimedia broadcasting technology. Mobile multimedia services have the advantages of high spectrum utilization, large capacity, relatively low construction cost, and wide audience, and have broad application prospects. [0003] China Mobile's multimedia broadcasting system clearly requires terminals to support all frequency points in the U-band 470MHz-798MHz frequency band. Such as figure 1 As shown in FIG. 2 , it is a schematic diagram of an architecture mode of an existing mobile multimedia playback technology and its processing procedure. It adopts a two-layer architecture model including user interface layer and system processing layer. When using the two-layer architecture mode, if the user performs...
