BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a personal video recorder. In detail, a plurality of broadcast signals having the same phase as an input broadcast signal are transmitted / received to a connection terminal of an internal HDD and an external HDD by an equal distribution pattern of a main printed circuit board (PCB). The main PCB equipped with the CPU, tuner, reader, and connector can be manufactured in a single design, but the external case which houses the main PCB and the auxiliary case or connector which is connected to the external case to support the external HDD can be used. It relates to a personal video recorder that can implement its structure and functionality.

In general, personal video recorders (PVRs) are becoming popular as devices for recording television programs for later viewing. PVRs, unlike tapes in video tape recorders, use a computer disk drive as a storage medium. This offers a variety of advantages, including the ability to pause a 'live' TV program currently being viewed, access the stored program or record multiple programs simultaneously. As these PVR devices become more popular, there is a problem that the internal storage provided in the PVR is not suitable for some users. Despite these problems, the existing basic set-top box does not support additional recording and storage methods, and has a disadvantage in that a function for connecting an external device is not supported. In order to solve this problem, a set-top box including a recording function and various functions has been released. However, there is a secondary problem that the manufacturing and market unit price is significantly higher than that of the existing basic set-top box, and that the size and weight of the product are relatively large compared to the existing basic set-top box.
