Abstract

The invention discloses a file playing method, which comprises: determining, in response to a file playing request, whether a directory of a current file to be played has been previously written intoa specific file; if YES, obtaining a playing grade in the specific file; if NO, directly playing the current file; determining whether the playing grade is greater than a system preset grade; if yes,locking the current file and popping up an unlock prompt; if no, directly playing the current file; and, when the unlock information is received and the unlock information conforms to the preset information, unlocking and playing the current file. The invention further discloses a file recording method, a playing device, playing equipment, a recording device, recording equipment and a playing system. The playing grade of the current pile can be effectively obtained, and the playing grade is determined.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a file playing method and device, and a file recording method and device. Background technique [0002] When digital TV is recorded, the EIT RF table (event information table) is generally written into the file. When the file is played in the recording list, it will start filtering and get the EIT RF information in the file, so as to obtain the current The level of the file, and then can control whether the current file can be played, and the recorded files played under the multimedia channel are generally decoded using the open source library FFmpeg. FFmpeg is a set that can be used to record and convert digital audio and video, and can convert them It is an open-source computer program converted into a stream, but the level of the file itself will be ignored in the process of decoding using FFmpeg in the prior art, resulting in files of unplayable levels still being a...
