【摘要】：本文研究了电视台节目收录时使用的收录系统。该系统的作用是通过三个子系统,完成电视台不同来源的节目的收录任务。整个系统以软硬件产生节目文件为系统开端,以太网为传输介质,节目管理、存储或者被制播网使用为最终目的,从而实现电视台节目的收录、传输与管理。本文中提出的收录系统,从业务角度主要分为AV收录、TS收录和IP收录三个子系统。其中AV收录和TS收录子系统通过软件和I/O卡进行信号的编解码,产生出节目文件,再使用以太网进行传输,将产生的节目文件放入存储中进行管理保存,或者将节目文件推送到其他制播网存储中被其他系统使用。IP收录则直接通过扫描网络路径,捕获最新的媒体文件来进行节目文件的收录。同AV收录和TS收录一样,捕获的文件在进行杀毒,解析,转码等工序之后,也由网络进行传输,拷贝到指定的存储中去。本文中提出的收录系统,从程序功能角度主要分为编单软件、收录控制中心、采集服务器、迁移服务器以及网络管理五大程序。通过BS编单软件,可以查询、新建、编辑和删除收录任务。控制中心从数据库中读取收录任务信息,并根据时间先后顺序产生节目单。采集服务器接受控制中心的命令控制。对收录的信号进行编码处理,使信号最终以媒体文件的形式进行保存。迁移服务器读取数据库中的记录,将媒体文件拷贝到收录网管中配置的存储中去,并添加数据库素材信息记录。收录网管修改系统的各个参数信息。其中包括存储路径信息,设备信息,信号管理,矩阵信号管理、用户及其权限等多种参数。收录系统不仅要满足电视台的传统业务,新媒体的业务也要得到更好的满足,一个可以同时进行AV收录、TS收录和IP收录,自动进行任务收录,节目自动拷贝分发的收录系统,有望在中国的广电市场上得到广泛的应用,为国家广电事业做出贡献。
[Abstract]:This paper studies the recording system used when TV programs are collected. The function of the system is to complete the collection task of TV programs from different sources through three subsystems. The whole system starts with the software and hardware generating program files. Ethernet is the transmission medium, program management, storage or use by the production and broadcast network for the ultimate purpose, so as to achieve the television program collection, transmission and management. From the business point of view, it is mainly divided into three subsystems: AV inclusion TS and IP recording. The AV and TS inclusion subsystem encode and decode the signal through software and I / O card to produce program files, and then use Ethernet for transmission. Put the generated program files into the storage for management and save, or push the program files to other broadcast network storage to be included by other systems using .IP, then directly scan the network path, Capture the latest media files to collect the program files. Like AV and TS, the captured files are transmitted by the network after anti-virus, parsing, transcoding and other processes. Copy to the designated storage. This paper proposed a collection system, from the point of view of program function, mainly divided into single software, collection control center, collection server, migration server and network management. Can query, create, edit and delete included tasks. Control center from the database to read included tasks information, According to the time sequence, the program is generated. The acquisition server receives the command control from the control center. The signals are encoded and processed. The migration server reads the records in the database and copies the media files to the storage configured in the network management. And add database material information record. Include network management modification system parameters information. Including storage path information, equipment information, signal management, matrix signal management, The system not only needs to satisfy the traditional service of TV station, but also the new media service should be better satisfied. One can collect AV TS and IP at the same time, and carry out task collection automatically. The program automatic copy distribution system is expected to be widely used in China's radio and television market and contribute to the national radio and television industry.
