Description

1235612 said _ ^ 1 ^ 92124868 V. Description of the invention (1) [Technical field to which the invention belongs] Zhi :: There is a personal secondary device for recording / playing TV programs according to categories, which is mainly applied to digital devices In particular, it relates to a method of recording and playing TV programs by personal video recorder (PVR) according to categories. [Previous technology] / / The multi-cable TV system is gradually changing, slowly from the analog TV system to the digital TV system, in the digital TV system, users can choose their own time at the time they want The programs you want to watch, so personalized TV system services will be a trend of future TV system services. Before digital TV can completely replace traditional TV, commonly known as Du: A video converter will become the core of this trend. After the traditional TV is connected with a video converter (commonly known as a set-top box), the traditional TV that can only receive analog signals can be converted to receive digital signals to generate an image. Therefore, with the cooperation of TV system service providers, use People can choose their favorite programs to watch. Today's hard disk drive is the support technology behind the development of video converters. Through the video converters of today's built-in hard disk drives, the video A converter has a personal video recording. (Hereinafter referred to as PVR), currently having pVR function is most likely to let users start using the built-in hardware One of the motivations of the video converter is that the pvR service allows cable TV customers to have the ability to control live TV, as well as to manage the big = channels provided by digital TV. Users can select programs to record and can pause and replay real-time The length of a recorded program or a live broadcast program varies depending on the size of the built-in hard disk. The functions of the currently known personal video recording device (pVR) mainly include recording
