Personal Video Recorder {Personal Video Recorder}

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 and received to a connection terminal of an internal HDD and an external HDD by an equal distribution pattern on 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 cost is significantly higher than that of the existing basic set-top box, and that the size and weight of the product are relatively larger than the conventional set-top box. Is raised.

In order to solve the above problems, it is convenient to use the set-top box as well as to solve the problem of difficulty in upgrading the existing basic set-top box, and to reduce the production and sales cost, and to reduce the size and weight of the conventional basic set-top box There is a need for a personal video recorder that is similar and easy to replace and store external HDDs.

The purpose of the present invention is to ease the use of the set-top box as well as to solve the problem of the difficulty in upgrading the existing basic set-top box,

Third, there is a useful effect that it is easy to replace and store the external HDD.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a personal video recorder 1 according to the first embodiment, which includes an exterior case 100 in which parts are built; A main PCB (200) mounted in the outer case (100) and mounted with a CPU (210) for controlling the system and a tuner (220) for tuning an input broadcast signal; Docked on the main PCB 200 includes an internal HDD 300 for storing the data of the input broadcast signal. One side of the external case 100 is further provided with an external HDD 400 for selectively docking and undocking the main PCB 200 and storing data of an input broadcast signal in a docked state on the main PCB 200.

The main PCB 200 is configured to transmit / receive a plurality of broadcast signals in phase with the input broadcast signal to the connection terminals of the internal HDD 300 and the external HDD 400 by an equal distribution pattern. As such, a plurality of broadcast signals having the same phase are transmitted to the internal HDD 300 and the external HDD 400 through the input broadcast signal along the path set in the equally distributed pattern on the main PCB 200, so that the user may receive the external case 100. By the simple operation of the recording unit 136 formed in the front portion 130 of the) can be selectively stored in the internal HDD 300 or the external HDD (400).

The main PCB 200 is provided with a reader 230 to which the smart card S supporting the DRM function is detachably connected. DRM protects the rights and interests of the provider of the input broadcast signal, prevents illegal copying, supports the entire creation, distribution, and management of the content of the broadcast signal, such as charging royalties and payment agency, and pays the appropriate fee for receiving the input broadcast. Digital copyright management technology, software and security technology for copyright approval and enforcement, and payment and payment technology. Preferably, the smart card (S) uses an electronic credit card that can hold a large amount of information by mounting a memory device of the ISO standard in which at least one IC is embedded.

2 is a flowchart illustrating a process of transmitting an input broadcast signal to a personal video recorder according to a first embodiment of the present invention. The process of transmitting an input broadcast signal to the personal video recorder 1 is as follows.

When the wired TV is connected to the personal video recorder 1 (S100), the CPU 210 mounted on the main PCB 200 detects whether or not the TV is turned on (S110). The tuner 220 mounted on the main PCB 200 of the personal video recorder 1 tunes a frequency displayable on the TV monitor with respect to the input broadcast signal (S120). In this case, the CPU 210 reads the ON time and channel information, moves to the corresponding channel, and displays the input broadcast signal on the TV monitor.

In addition, the CPU 210 mounted on the main PCB 200 detects whether the smart card S is connected to the reader 230 (S130). When the smart card S is connected, an input broadcast signal is stored in the internal HDD 300 and the external HDD 400 along a predetermined path of the main PCB 200 in a state in which the DRM function is supported (S140). When the smart card (S) is not connected, the input broadcast signal is stored in the internal HDD 300 and the external HDD 400 along a predetermined path of the main PCB 200 in a state in which the DRM function is released (S150). .

The process of storing the broadcast signal is as follows.

When the TV connected by wire to the personal video recorder 1 is turned on (S200), the CPU 210 mounted on the main PCB 200 detects whether the TV is turned on and operates. The tuner 220 mounted on the main PCB 200 of the personal video recorder 1 tunes the displayable frequency on the TV monitor with respect to the input broadcast signal, in which case the CPU 210 reads on time and channel information. Moving to the corresponding channel, the input broadcast signal is displayed on the TV monitor (S210).

The CPU 210 mounted on the main PCB 200 detects whether the external HDD 400 is connected to the access unit 110 formed at one side of the external case 100 (S220). When the external HDD 400 is not connected to the access unit 110 of the external case 100, the input broadcast signal is recorded by the recording unit 136 of the front unit 130 disposed in front of the external case 100. Select whether to store (S250) in the internal HDD (300). When the external HDD 400 is connected to the access unit 110 of the external case 100, it is determined whether the external HDD 400 is stored in the external HDD 400 or the internal HDD 300 (S230). By the operation of the recording unit 136 is stored in the internal HDD 300 of step S250 or selectively stored in the external HDD 400 of step S240.
