ＰＶＲ시스템의 녹화장치 및 방법{RECORDING APPARATUS AND METHOD FOR PVR SYSTEM}Recording system and method of PPR system {RECORDING APPARATUS AND METHOD FOR PVR SYSTEM}

본 발명은 PVR시스템의 녹화장치 및 방법에 관한 것으로, 특히 사용자가 원격지에서 원하는 프로그램을 자유롭게 녹화할 수 있도록 한 PVR시스템의 녹화장치 및 방법에 관한 것이다.The present invention relates to a recording apparatus and method of a PVR system, and more particularly, to a recording apparatus and method of a PVR system that allows a user to freely record a desired program at a remote location.

최근 PVR시스템이 본격적으로 보급되고 있는데, 특히 디지탈방송의 시작과 더불어 티브이나 셋톱박스등에 PVR기능을 추가하는 추세가 일반화되고 있다.Recently, the PVR system is spreading in earnest. Especially, with the start of digital broadcasting, the trend of adding PVR functions to TVs and set-top boxes is becoming common.

상기 PVR 시스템은 티임시프트/레코딩이 주된 기능으로, 레코딩기능은 VCR녹화를 대체한다.In the PVR system, tee-shift / recording is a main function, and a recording function replaces a VCR recording.

이러한, PVR시스템에서 방송을 녹화하는 방법은, 일반 VCR처럼 직접 녹화하거나 예약 녹화를 수행하는데, 사용자가 원격지에 나가 있는 경우, 예약되어 있는 방송외에는 프로그램을 녹화하지 못한다.Such a method of recording a broadcast in the PVR system is to record directly or schedule recording like a normal VCR, but when a user goes out to a remote place, a program cannot be recorded except a reserved broadcast.

즉, 사용자가 직접 PVR 시스템을 조작할 수 없는 경우, 상기 PVR 시스템은 미리 예약을 하지 않으면, 원하는 프로그램이 있어도 녹화하지 못하는 문제점이 잉있다.In other words, if the user cannot directly operate the PVR system, the PVR system may not record even if a desired program is not reserved in advance.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 사용자가 원격지에서 원하는 프로그램을 자유롭게 녹화할 수 있도록 한 PVR시스템의 녹화장치 및 방법을 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, and an object thereof is to provide a recording apparatus and method of a PVR system that allows a user to freely record a desired program at a remote location.

도1은 PVR시스템의 녹화장치에 대한 구성을 보인 블록도로서, 이에 도시한 바와같이 전화라인 및 라인 인터페이스(1)를 통해 입력되는 링신호를 검출하는 링검출부(2)와; 상기 링검출부(2)에 의해, 슬립모드에서 시스템을 웨이크업시키는 씨피유(6)와; 원격 녹화를 위한 안내 메시지를 음성 데이터로 기저장함과 아울러 녹화하고자 하는 방송이 저장되는 HDD(7)와; 상기 씨피유(6)의 제어에 의해, 상기HDD(7)의 음성 데이터를 입력받아 이를 아날로그로 변환하여 라인 인터페이스(1)를 통해 사용자에게 전송하는 디지탈/아날로그 변환기(3)와; 사용자에 의해 송신되는 채널번호 및 녹화시간을 디코딩하여 상기 씨피유(6)에 인가하는 DTMF디코더(4)와; 녹화하고자 하는 방송을 코딩하여 상기 HDD(7)에 저장하는 엠펙엔코더(9)와; 상기 HDD(7)에 저장된 방송을 디코딩하여 화면에 출력하는 엠펙디코더(8)로 구성한다.Fig. 1 is a block diagram showing the configuration of a recording apparatus of a PVR system, as shown therein; a ring detection section 2 for detecting a ring signal input through a telephone line and a line interface 1; The CPI (6) for waking up the system in the sleep mode by the ring detecting unit (2); An HDD 7 for pre-storing the announcement message for remote recording as voice data and storing a broadcast to be recorded; A digital / analog converter (3) for receiving audio data of the HDD (7) under the control of the CPI (6), converting the voice data into an analog, and transmitting the analog data to a user through a line interface (1); A DTMF decoder 4 for decoding the channel number and the recording time transmitted by the user and applying the decode to the CPI 6; An MPEG encoder (9) for coding a broadcast to be recorded and storing it in the HDD (7); An MPEG decoder 8 which decodes a broadcast stored in the HDD 7 and outputs it to a screen.

도2는 본 발명 PVR시스템의 녹화방법에 대한 동작흐름도로서,이에 도시한 바와같이 사용자에 의한, 링신호가 검출되면 PVR시스템을 웨이크업 시키는 제1 과정과; 사용자에 의해 선택된 녹화채널 및 녹화시간을 수신하는 제2 과정과; 상기 녹화채널 및 녹화시간에 따라, 해당되는 방송을 녹화한후 슬립모드로 전환하는 제3 과정으로 이루어지며,이와같은 본 발명의 동작을 설명한다.2 is an operation flowchart of a recording method of a PVR system according to the present invention, and the first step of waking up the PVR system when a ring signal is detected by a user as shown in FIG. A second step of receiving a recording channel and a recording time selected by a user; According to the recording channel and the recording time, a third process of recording a corresponding broadcast and then entering a sleep mode is described. The operation of the present invention will be described.

먼저, PVR시스템이 파워 슬립 모드인 상태에서, 사용자가 원하는 방송을 녹화하기 위해 전화라인을 통해 PVR시스템에 전화를 건다.First, while the PVR system is in the power sleep mode, the user calls the PVR system through a telephone line to record a desired broadcast.

그러면, 상기 PVR시스템의 링검출부(2)는 전화라인 및 라인 인터페이스(1)를 통해 입력되는 링신호를 검출하여 그 링신호를 씨피유(6)에 인가하고, 이에 따라, 씨피유는 상기 상기 링검출부(2)에 링신호에 의해, 슬립모드에서 시스템을 웨이크업시킨다.Then, the ring detection unit 2 of the PVR system detects a ring signal input through the telephone line and the line interface 1 and applies the ring signal to the seed oil 6, whereby the seed oil is the ring detector. The ring signal in (2) wakes up the system in the sleep mode.

이후, 상기 씨피유(6)는 HDD(7)에 기저장된 원격 녹화를 위한 안내 메시지를 음성 데이터를 디지탈/아날로그변환기(3)에 인가하도록 제어하고, 그러면, 상기 디지탈/아날로그변환기(3)는 상기 음성데이터를 아날로그로 변환하여 라인인터페이스 (1)를 통해 사용자에게 송신한다.Thereafter, the CPI 6 controls to apply voice data to the digital / analog converter 3 for a guidance message for remote recording pre-stored in the HDD 7. Then, the digital / analog converter 3 The voice data is converted into analog and transmitted to the user through the line interface (1).

상기 안내메시지는, 채널번호 입력을 요구하는 메시지와 녹화시간 길이를 요구하는 메시지로 이루어진다.The guide message includes a message for requesting input of a channel number and a message for length of recording time.

이에 따라, 사용자는 원하는 채널번호와 녹화시간길이를 전화기의 버튼키신호로 입력하여 송신하고, 그러면 PVR시스템의 DTMF디코더(4)는 버튼키신호의 주파수를 디코딩하여 그에 해당되는 채널번호와 녹화시간 길이를 상기 씨피유(6)에 인가한다.Accordingly, the user inputs and transmits a desired channel number and a recording time length as a button key signal of a telephone, and then the DTMF decoder 4 of the PVR system decodes the frequency of the button key signal to correspond to the corresponding channel number and recording time. The length is applied to the seed oil 6.

그러면, 씨피유(6)는 해당 채널번호를 튜닝하여 원하는 방송을, 사용자에 의해 설정된 녹화시간 길이 만큼 녹화 수행한후, 녹화시간이 경과하면 슬립 모드로 전환한다.Then, the C 6 performs recording of the desired broadcast by tuning the corresponding channel number by the recording time length set by the user, and then switches to the sleep mode when the recording time elapses.

보다 상세하게 도2를 참조하여 설명하면, 우선, 사용자에 의한, 링신호가 검출되면 PVR시스템을 웨이크업 시키는데, 즉 링검출부(2)에 의해, 링신호가 소정 회수 이상이면 PVR시스템을 웨이크업시켜 동작시킨다.Referring to FIG. 2 in more detail, first, when a ring signal is detected by a user, the PVR system wakes up, that is, by the ring detector 2, when the ring signal has a predetermined number or more, the PVR system wakes up To operate.

그 다음, 사용자에 의해 선택된 녹화채널 및 녹화시간을 수신한다.Then, the recording channel and the recording time selected by the user are received.

즉, 녹화채널 번호 입력 요구메시지를 송신한후,채널번호를 수신하고, 해당 채널 번호가 튜닝되면 녹화시간 길이 입력 요구 메시지를 송신한후, 녹화시간 길이를 수신한다.That is, after the recording channel number input request message is transmitted, the channel number is received. If the channel number is tuned, the recording time length input request message is transmitted, and then the recording time length is received.

상기 채널번호와 녹화 시간길이는, DTMF디코더에 의해, 사용자가 입력하는 버튼신호의 주파수를 디코딩하여 수신한다.The channel number and the recording time length are decoded and received by the DTMF decoder with the frequency of the button signal input by the user.

상기 녹화채널 번호 입력 요구메시지와 녹화시간 길이 요구 메시지는 음성데이터로 HDD에 기저장된다.The recording channel number input request message and the recording time length request message are previously stored in the HDD as voice data.

상기 본 발명의 상세한 설명에서 행해진 구체적인 실시 양태 또는 실시예는 어디까지나 본 발명의 기술 내용을 명확하게 하기 위한 것으로 이러한 구체적 실시예에 한정해서 협의로 해석해서는 안되며, 본 발명의 정신과 다음에 기재된 특허 청구의 범위내에서 여러가지 변경 실시가 가능한 것이다.The specific embodiments or examples made in the detailed description of the present invention are intended to clarify the technical contents of the present invention to the extent that they should not be construed as limited to these specific embodiments and should not be construed in consultation. Various changes can be made within the scope of.

이상에서 상세히 설명한 바와같이 본 발명은, 사용자가 직접 녹화할 수 없는 경우에도, 전화기 하나만으로 원하는 방송 프로그램을 간단히 녹화하는 효과가 있다.As described in detail above, the present invention has the effect of simply recording a desired broadcast program with only one telephone, even when the user cannot record directly.

또한, ARS방식을 이용하여 단계별로 프로그램 녹화를 수행함으로써 사용자에게 프로그램 녹화의 편의를 제공하는 효과가 있다.In addition, there is an effect of providing a program recording convenience to the user by performing the program recording step by step using the ARS method.
