Problems solved by technology

[0004] When it is necessary to edit the unified material, the material can only be edited one by one, and the unified editing cannot be realized, and the attributes of the material cannot be managed and utilized in a unified way, resulting in a lot of duplication of labor and increasing the probability of errors
[0005] At the same time, since the information matching between the broadcast control system and the subtitle machine can only be carried out manua

no. 1 example

[0038] see figure 1 , the first embodiment of the method of the present invention, the method that the play control system sends the program list to the subtitle machine to generate the subtitle program list file through the method includes:

[0039] D1) Generate program list

[0040] The broadcast control system generates the program list file, usually through the broadcast control system including: a disk array, a call unit, and a broadcast control machine. The broadcast control machine performs the generation of the program list file, and in this program list file, at least To include the material number ID, this number corresponds to the corresponding material number ID in the disk array in the playback control system.

[0041] D2) Generating material timing program list

[0042] After the program list file of the broadcast control system is generated, the attributes of a certain type of material can be extracted. For example, in the program list, there is an attribute fil...

[0054] see figure 2 , the second embodiment of the method of the present invention specifically includes:

[0055] P1) Generate program list

[0056] The process of generating the program list in this embodiment is the same as that in the first embodiment.

[0057] P2) Generate material timing program list

[0058] The process of generating material timed program list in this embodiment is the same as that in the first embodiment.

[0059] P3) for format encapsulation

[0060] The format encapsulation process in this embodiment is the same as that in the first embodiment.

[0062] The sending process in this embodiment is the same as that in the first embodiment.

[0063] P5) Receive

[0064] When the subtitle machine receives the material timing program list sent by the broadcast control system, it will display the received material timing program list file information of the broadcast control system on the user display interface of the subtitle mach...

Embodiment 3

[0075] see image 3 , in Embodiment 1 of the present invention D5) the file parsing step can also specifically include:

[0076] Q1) Perform file parsing:

[0077] Analyze the file format of the material timing program list file sent by the broadcast control system to the subtitle machine, and restore the material timing program list file;

[0078] Q2) Identification:

[0079] Judging whether the material timing program list file is an identifiable file format, if so, then sending the material timing program list file to the subtitle machine to be processed program list list and jumping to Q3, otherwise, the subtitle machine starts an error processing program That is, jump to Q4.

[0080] Q3) Sent to the subtitle machine to be processed material timing program list list:

[0081] Store the recognized material timing program list file in the subtitle machine's pending program list or cache.

[0082] Q4) Start error processing:

[0083] Give further processing to the situa...

Abstract

The invention discloses a synchronous manufacturing method and a synchronous manufacturing system of character generator timing materials, mainly relating to the field of broadcast television programming and broadcasting. The method comprises the following steps that: 1) a broadcast control system generates a program list file; 2) the broadcast control system extracts an attribute list of general materials in the program list file, and generates a material timing program list according to a timing material list; 3) the broadcast control system carries out format packaging on the material timing program list file according to a protocol format, and the broadcast control system transmits the packaged material timing program list to a character generator; and the character generator receives the material timing program list; 4) the character generator analyzes the file according to the protocol format so as to restore the material timing program list file; and 5) the character generator generates a subtitle file according to the material timing program list file; and the system comprises a broadcast control unit, a material attribute program list generating unit, a protocol packaging unit, a protocol analyzing unit and a character generator unit. Therefore, the material generality attribute of the program list file in the broadcast control system is extracted; a common timing subtitle is endowed according to the requirements on a material attribute subtitle; and moreover a uniform material timing list is generated so as to generate the subtitle file, so that the uniform subtitle editing process on materials of same attribute is solved; and the subtitle files of such kind are generated and processed uniformly.

Description

technical field [0001] The invention relates to the field of production and broadcasting of radio and television programs, in particular to a method and system for synchronous production of subtitle machine timing materials. Background technique [0002] In the field of radio and television program production and broadcasting, a large amount of subtitle synthesis processing is required in the process of program material production to meet the needs of program material broadcasting. The subtitle synthesis method in the prior art is that the broadcasting control system The control computer generates the program list file, and copies the program list file to the subtitle machine. The subtitle machine makes subtitles according to the program list file. On the one hand, because there is no communication between the broadcast control system and the subtitle machine, it needs to be manually moved Storage device, copy the program list file in the broadcast control machine to the sub...
