The invention may be described in the general context of computer-executable instructions, programs, and programs being executed by a computer
As shown in fig. 1, a method for controlling multimedia content display to multiple sites remotely according to the present invention specifically includes the following steps:
s101, acquiring an exhibition hall multimedia playing material arranged at a first control end;
the specific steps of setting the multimedia playing materials are shown in fig. 2, and include starting to set a plan, setting a plan name, selecting corresponding exhibition equipment, adding screens, setting screen names, and adding task types. The step is convenient for uniformly setting the multi-inner-body playing material resources.
The added task types mainly comprise a playing task, a webpage task and an instruction task, after the task types are added, the playing attribute is set, the set playing material is added, the setting is submitted, the plan is applied, and finally the setting of the plan is finished, and the setting of the whole first control end on the playing material is completed. The playing material includes playing material resources, playing sequence and time period, and the playing material resources include characters, pictures, videos, and the like, but are not limited to the above playing material.
The first control end in the application can select a group headquarter or a superior exhibition hall in the multimedia field of the exhibition hall, the setting steps of the playing materials are convenient for unified setting, and the multimedia playing material resource content of the group headquarter and the sub exhibition hall is favorably unified.
S102, updating a preset playing material of a first control end to a public network cloud server;
as shown in fig. 3, the playing material update specifically includes the following steps:
the cloud platform sends a plan updating instruction 301 to the central control, the central control requests a plan 302 after receiving the plan updating instruction, and the cloud platform receives the plan requesting instruction of the central control and acquires a plan 303;
the central control receives a plan obtaining instruction of the cloud platform and then sends a request resource 304 to the cloud platform, the cloud platform obtains a resource 305, the central control receives a resource downloading request instruction 306 sent by the cloud platform and sends the resource downloading request instruction to the cloud disk;
the cloud disk receives the instruction of requesting to download the resource and downloads the resource 307;
the central control receives the download resource of the cloud disk to store the resource 308, and applies the plan 309. The playing material is updated to the cloud end, and the cloud end is stored, installed, convenient and backup, and does not depend on any hardware equipment. Greatly reduces the cost of updating the plan and is convenient for unified management.
The specific flow of plan updating and obtaining is shown in fig. 9, when the central control is started or receives a plan updating instruction, all plan data of the exhibition hall are requested from the management background, then the plan data are analyzed, whether different positions exist in the plan data or not is judged, if the different positions do not exist, the data are stored in the memory, the plan data are broadcasted to all the broadcast control servers through the message middleware, after the broadcast control servers receive the plan data, the plan data are analyzed, the own plan data are partially reserved, the data needed by the broadcast control are compared with the originally stored data, if the different positions do not exist, the plan updating operation is carried out, and if the different positions do not exist, the plan updating operation is not carried out, so that all the broadcast controls are prevented from updating the plan operation due to a little content modification.
In actual operation, when the upper exhibition hall sets a sharing plan for the lower exhibition hall, whether the sharing plan is shared in the existing plan is determined, if the upper exhibition hall does not want to share the content in the existing plan, another plan can be newly added, and the screen to be shared and the task editing are completed in the corresponding plan and the exhibition area.
And finishing the task editing, wherein the option appointed to the lower exhibition hall is set to be yes in the playing setting, so that the operation of sharing the plan of the upper exhibition hall is finished. It should be noted here that the sharing plan is set as the master newly, and the newly set sharing plan will override the previous sharing plan. And clicking an application plan button to send an instruction to the central control, so that the central control downloads newly added data such as plans, screens, tasks, resources and the like. The plan shared by the upper exhibition hall can be issued to the lower exhibition hall and the exhibition halls corresponding to the lower exhibition hall, and the plan sharing is completed.
S103, sending a playing material preset by the shared first control end to the second control end;
the broadcast material issuing and sharing is shown in fig. 4, and specifically includes the following steps:
starting a central control 401, sending an instruction for requesting a plan 402 to a cloud platform, receiving the instruction for requesting the plan by the cloud platform, and acquiring a plan 403;
the central control receives a plan obtaining instruction of the cloud platform and then sends a resource requesting instruction 404 to the cloud platform, the cloud platform obtains resources 405, the central control receives a resource downloading requesting instruction 406 sent by the cloud platform and sends the resource downloading requesting instruction to the cloud disk;
the cloud disk receives the instruction of requesting to download the resource and downloads the resource 407;
the central control receives the download resource of the cloud disk to store the resource 408 and applies the plan 409. The sharing is issued, the cross-space-time transmission is convenient and quick, the manpower and material resources are saved, and the resource content transmission efficiency is improved.
S104, receiving a playing material shared by the first control end to the second control end, carrying out token verification, and receiving the playing material after the verification is successful;
the token verification specifically comprises the following steps:
the first control end sends updated information to the central control of the second control end, and token information is set;
the second control end sends a request data issuing instruction to the first control end and sends a token checking request;
the first control end receives a token checking request of the second control end, then token information checking is carried out, and authentication identity is judged;
when the identity is verified to be qualified, the first control end allows the data to be issued and ends the identity verification;
otherwise, the authentication fails, and the authentication is directly finished.
The token is adopted to verify the identity in two directions, so that the accuracy of information transmission can be greatly improved, and the installation is guaranteed.
The second control end can select sub-enterprise, sub-exhibition hall, subordinate exhibition hall or subordinate exhibition hall in the exhibition hall multimedia field, and when the subordinate exhibition hall receives the sharing plan of higher level exhibition hall, the plan and the exhibition district that will receive are selected earlier, click the broadcast setting after the plan exhibition district is selected well, will connect higher level's exhibition hall option and set up to be yes, accomplish sharing plan and receive.
