The Design And Implementation Of Video Automatically Record Systems

This thesis presents the video recording system for Televisions. The usefulness of the system will be completed the tasks of collection television through the three subsystems. The whole system is based on hardware and software. used Ethernet as the transmission medium. The program management, storage and television programs used by the broadcast network is the ultimate aim. The video recording system completed the collection, transmission and management of television programs.The video recording system proposing by this paper, included the AV collection, the TS collection and the IP collection three subsystems. Which included the AV collection and the TS collection subsystem software and I / O card encoding and decoding signals to produce a program file, and then use the Ethernet transmission, the program files will be generated into the store manage to save, or program files pushed to the other broadcast network storage system to be used in other systems. IP indexed directly by scanning the network path, catch the latest media files to be included in the program files. Included with the AV collection and TS as captured files after making anti-virus, analytical, transcending and other processes, but also by the network transmission, copied to the specified storage to go.The video recording system proposing by this paper, from the perspective of the main program functions into a single software compiled a collection of the control center, acquisition server, migrate servers and network management of the five programs. BS compiled by a single software, you can query, create, edit, and delete tasks included. Indexed mission control center to read information from the database, and according to the time the order to produce a single program. Command Control Center accepts acquisition server control. The signal is encoded for inclusion in processing the signal in the form of the final media files to be saved. Migrating server reads the database record, copy media files to a collection network configured to store and add database information recording material. Network management system included modifying various parameters. These include a variety of parameters stored path information, equipment information, signal management, matrix signal management, users and their permissions.The video recording system not only to meet the traditional business of television and new media business should be better met, one can be included AV, TS and IP collection included the same time, the task is automatically included, the program automatically copies distributed collection system, is expected to China’s broadcasting market has been widely used on national radio and television contribute to the cause.
