Problems solved by technology

[0004] 1. When the program list changes, the order and priority of media preparation cannot be adjusted in a timely and dynamic manner, which may cause some media files to fail to be prepared to the broadcast video server on time;
[0005] 2. The preparation of the programs is carried out in the order of the broadcast time, but in some special cases, the programs that will be broadcast later may need to start preparations earlier. If the preparations are strictly in accordance with the broadcast time, there may be programs that cannot Completion of preparations on time;
[0006] 3. If there is a change in the program preparation, manual adjustments are often required, which not only requires a large amount of manual work, but also brings about some manual errors, which will affect the safety of broadcasting in severe cases

Embodiment 1

[0026] This embodiment is a method for preparing media files that can dynamically adjust priorities in real time. The system used in the method includes: a broadcast video server with storage, a secondary storage for broadcast, a near-line storage for broadcast, and multiple Migration cluster, maintenance management server, playbill editor, and database composed of three migration servers. The system as figure 1 shown.

[0027] The steps of the method are as follows:

[0028] The step of updating the program list in real time: the preparation management server receives the latest program list to be broadcast in real time, and saves the latest program list to be broadcast in the database. The method described in this embodiment is applied in the broadcasting process of the TV station, and once the broadcasting process is started, it is a continuous process under normal circumstances. There are constantly new program lists entering the preparation management server for prepar...

Embodiment 2

[0051] This embodiment implements the improvement of the first embodiment, which is the refinement of the first embodiment about the closing time. The closing time described in the present embodiment is calculated as follows:

[0052] The closing time of the video server is: n×Ta+C,

[0053] Where: Ta is the duration of the program, n is the coefficient of the migration time, and C is the protection time of the program in the video server.

[0054] The closing time of broadcast secondary storage is: (m×Ta+E)+(n×Ta+C),

[0055] Among them: Ta is the duration of the program, m is the efficiency of program preparation to the secondary storage, E is the protection time of the program in the secondary storage, n*Ta+C is the closing time of the program in the video server.

[0056] Both E and C in the above formula are constants, which are the margin protection time, and C is the protection time of the video server. Considering that the migration efficiency of program files is relat...

Abstract

The invention relates to a media file hostling method capable of regulating a priority level dynamically and in real time. The media file hostling method capable of regulating the priority level dynamically and in real time comprises the following steps: updating a playbill in real time; searching a to-be-played program; emergency processing; calculating closing time; confirming the priority level of the to-be-played program; detecting working state of a migration cluster; regulating the working state of the migration cluster: starting a free migration server; changing the migration; holding the migration; and emergency hostling. According to the media file hostling method capable of regulating the priority level dynamically and in real time, the problem of dynamic regulation for the program files in the migration process can be solved, broadcast safe hidden trouble caused by that the program is prepared simply according to broadcast sequence can be avoided, automatic program hostling is achieved, workload of workers is reduced, and accuracy and safety are improved.

Description

technical field [0001] The invention relates to a method for preparing media files that can dynamically adjust priorities in real time. It is a method for transmitting media files through a network, and is used in a broadcasting system of a TV station to ensure that the programs broadcast by the TV station are timely, normal and orderly. method of preparation. Background technique [0002] With the popularization of networking and documentation, the broadcasting system of TV stations has changed from traditional tape broadcasting to program file broadcasting. In addition, since other business links of the TV station, such as the program production system, program storage system, and program recording system, have been documented, the preparation of the TV station's programs to be broadcast can be carried out through file network transmission, instead of using the traditional The videotape delivery was carried out. [0003] The preparation of the programs to be broadcast in...
