【摘要】：本文研究了電視臺(tái)節(jié)目收錄時(shí)使用的收錄系統(tǒng)。該系統(tǒng)的作用是通過三個(gè)子系統(tǒng),完成電視臺(tái)不同來源的節(jié)目的收錄任務(wù)。整個(gè)系統(tǒng)以軟硬件產(chǎn)生節(jié)目文件為系統(tǒng)開端,以太網(wǎng)為傳輸介質(zhì),節(jié)目管理、存儲(chǔ)或者被制播網(wǎng)使用為最終目的,從而實(shí)現(xiàn)電視臺(tái)節(jié)目的收錄、傳輸與管理。本文中提出的收錄系統(tǒng),從業(yè)務(wù)角度主要分為AV收錄、TS收錄和IP收錄三個(gè)子系統(tǒng)。其中AV收錄和TS收錄子系統(tǒng)通過軟件和I/O卡進(jìn)行信號(hào)的編解碼,產(chǎn)生出節(jié)目文件,再使用以太網(wǎng)進(jìn)行傳輸,將產(chǎn)生的節(jié)目文件放入存儲(chǔ)中進(jìn)行管理保存,或者將節(jié)目文件推送到其他制播網(wǎng)存儲(chǔ)中被其他系統(tǒng)使用。IP收錄則直接通過掃描網(wǎng)絡(luò)路徑,捕獲最新的媒體文件來進(jìn)行節(jié)目文件的收錄。同AV收錄和TS收錄一樣,捕獲的文件在進(jìn)行殺毒,解析,轉(zhuǎn)碼等工序之后,也由網(wǎng)絡(luò)進(jìn)行傳輸,拷貝到指定的存儲(chǔ)中去。本文中提出的收錄系統(tǒng),從程序功能角度主要分為編單軟件、收錄控制中心、采集服務(wù)器、遷移服務(wù)器以及網(wǎng)絡(luò)管理五大程序。通過BS編單軟件,可以查詢、新建、編輯和刪除收錄任務(wù)�？刂浦行膹臄�(shù)據(jù)庫中讀取收錄任務(wù)信息,并根據(jù)時(shí)間先后順序產(chǎn)生節(jié)目單。采集服務(wù)器接受控制中心的命令控制。對收錄的信號(hào)進(jìn)行編碼處理,使信號(hào)最終以媒體文件的形式進(jìn)行保存。遷移服務(wù)器讀取數(shù)據(jù)庫中的記錄,將媒體文件拷貝到收錄網(wǎng)管中配置的存儲(chǔ)中去,并添加數(shù)據(jù)庫素材信息記錄。收錄網(wǎng)管修改系統(tǒng)的各個(gè)參數(shù)信息。其中包括存儲(chǔ)路徑信息,設(shè)備信息,信號(hào)管理,矩陣信號(hào)管理、用戶及其權(quán)限等多種參數(shù)。收錄系統(tǒng)不僅要滿足電視臺(tái)的傳統(tǒng)業(yè)務(wù),新媒體的業(yè)務(wù)也要得到更好的滿足,一個(gè)可以同時(shí)進(jìn)行AV收錄、TS收錄和IP收錄,自動(dòng)進(jìn)行任務(wù)收錄,節(jié)目自動(dòng)拷貝分發(fā)的收錄系統(tǒng),有望在中國的廣電市場上得到廣泛的應(yīng)用,為國家廣電事業(yè)做出貢獻(xiàn)。
[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.
