Problems solved by technology
However, in practical applications, using software to convert video file formats on a personal computer has many disadvantages, including high difficulty in setting, high requirements for computer equipment, and slow file conversion speed
Furthermore, current video file conversion software can only allow users to convert existing digital video files into desired formats, but cannot allow users to directly convert non-file video streams, such as various TV broadcast programs (wired / wireless / satellite broadcast)
If users want to make various broadcast and TV programs into digital video files, they first need to install related hardware TV cards or receivers on their personal computers, so more hardware costs are required
In addition, using software to convert video files on a personal computer usually requires a series of extremely cumbersome installation and operation procedures by the user, so it is not convenient to use

A programmable scheduling conversion device for video files can be applied to a plurality of video sources of various types, such as cable televisions, digital televisions, US digital videos, JP digital videos, satellite set-top boxes, CD players, digital cameras and monitoring cameras, generated video signals thereof (comprising analog and digital signals) or various digital video files are converted into digital video files with the formats specified by users. The programmable scheduling conversion device for video files is characterized by comprising a programmable file conversion scheduling function and utilizing a hardware-type video format conversion chip rather than a traditional computer software program to execute conversion of the video formats, and thereby compared with the background technique, the conversion speed of the programmable scheduling conversion device for video files is faster.
Description
technical field [0001] The present invention relates to a digital video technology, in particular to a video file conversion device with programmable scheduling, which can be applied to a variety of different types of video sources, such as cable TV, digital TV, and American standard digital video , Japanese standard digital video, satellite set-top box, CD / DVD disc player, digital camera, and surveillance camera, the video signal generated by it or various digital video files in the computer are converted into digital video files in the format specified by the user . Background technique [0002] Traditionally, video file formats for personal computers include, for example, AVI, WMV, MOV, and MPG. However, with the development of computer technology, there are currently many portable multimedia players (Portable Multimedia Player, PMP), such as iPod, Sony PSP (PlayStation Portable), and NINTENDO NDS, which use their own unique formats to play digital media. video file. ...
