Description

ＰＶＲ의 영상 서비스 방법{IMAGE SERVICE METHOD OF PVR}Image service method of PVR <{SERVICE METHOD OF PVR}

본 발명은 PVR(Personal Video Recorder)의 영상 서비스 방법에 관한 것으로, 특히, PVR이 고화질의 영상을 HDTV(High-Definition TeleVision)로 서비스하는 방법에 관한 것이다.The present invention relates to a video service method of a personal video recorder (PVR), and more particularly, to a method of providing a high-definition video by a high-definition television (HDTV).

일반적으로 PVR은 방송 프로그램이나 관련 콘텐츠(contents) 예로, 방송자료, 문자, 사진 등을 디지털 방식으로 저장하고 이를 언제든지 고화질로 즉시 재생할 수 있다. 저장 매체(storage media)로는 주로 HDD(Hard Disc Drive)가 사용되고 TV와 연결하여 작동하는 일종의 STB(Set-Top-Box)이다. HDD에 녹화되는 소스(source) 신호는 일반 아날로그/디지털 공중파나 위성방송 신호이다. HDD에 디지털 데이터를 저장하기 때문에 타임 시프트(time-shift), 예약녹화, 편집기능 등의 다양한 부가기능을 구현할 수 있다.In general, a PVR can digitally store a broadcast program or related contents, for example, broadcast data, texts, and pictures, and immediately reproduce them in high quality at any time. Storage media is mainly a hard disc drive (HDD) and is a kind of STB (Set-Top-Box) that operates by connecting to a TV. The source signal recorded on the HDD is a general analog / digital airwave or satellite broadcast signal. Because digital data is stored on the HDD, various additional functions such as time-shift, scheduled recording, and editing can be implemented.

그러나, 이와 같은 종래의 기술에 있어서는 영상 서비스가 제약되어 PC(Personal Computer) 기반 네트웍 멀티미디어 데이터베이스(network multimedia database)의 콘텐츠를 서비스하지는 못했다.However, in such a conventional technology, video service is restricted and thus it is not possible to service contents of a personal computer (PC) based network multimedia database.

본 발명은 상술한 결점을 해결하기 위하여 안출한 것으로, PVR과 PC를 무선 이더넷 어댑터(wireless ethernet adaptor)로 연결시켜 PVR이 DTV(Digital TeleVision) 지상파 방송신호 뿐만 아니라 PC 기반 네트웍 멀티미디어 데이터베이스의 콘텐츠를 서비스하도록 하는 PVR의 영상 서비스 방법을 제공하는 데 그 목적이 있다.The present invention has been made to solve the above-mentioned shortcomings, and the PVR connects the PC with a wireless ethernet adapter so that the PVR can service not only DTV (Digital TeleVision) terrestrial broadcasting signals but also contents of a PC-based network multimedia database. The purpose is to provide a video service method of the PVR.

PVR(20)은 PC(10)가 인증을 해주면 PC(10)에게 PC(10)용 프로그램 EPG 정보를 요청한다(단계 30).When the PC 10 authenticates, the PVR 20 requests the PC 10 program EPG information for the PC 10 (step 30).

PC(10)는 PVR(20)의 프로그램 EPG 요청에 따라 구축된 PC(10)용 EPG 정보를 PVR(20)로 전송한다(단계 32).The PC 10 transmits the EPG information for the PC 10 constructed according to the program EPG request of the PVR 20 to the PVR 20 (step 32).

PVR(20)은 자체의 EPG와 전송받은 PC(10)의 EPG 정보를 합성하여 PVR(20)과 PC(10)를 결합한 프로그램 재생목록을 구축하고 그 결과를 PVR 사용자용 OSD 메뉴(On Screen Display menu)에 HDTV를 통해 나타낸다(단계 34).The PVR 20 constructs a program playlist combining the PVR 20 and the PC 10 by synthesizing the EPG information of the PC 10 with its own EPG and displaying the result of the OSD menu (On Screen Display) for the PVR user. menu) via HDTV (step 34).

PVR(20)은 PVR 사용자가 해당 OSD 메뉴에서 선호하는 프로그램을 선택하고 그 정보의 위치가 PVR(20) 상에 존재하면 네트웍 인터페이스 모듈(22)과 DTV 디코더(24)를 통해 해당 프로그램을 HDTV에 디스플레이시킨다(단계 36). 반면, PVR(20)은 그 위치가 PC(10) 상에 존재하면 무선 이더넷 액세스 포인트(26)를 통하여 PC(10)에게 해당 프로그램에 대한 스트림을 요청한다(단계 38).If the PVR user selects a favorite program from the corresponding OSD menu and the location of the information is on the PVR 20, the PVR 20 transmits the corresponding program to the HDTV through the network interface module 22 and the DTV decoder 24. Display (step 36). On the other hand, if the location is on the PC 10, the PVR 20 requests a stream for the program from the PC 10 via the wireless Ethernet access point 26 (step 38).

PC(10)는 PVR(20)의 요청에 따른 스트림을 PVR(20)로 무선 이더넷 어댑터(16)를 통하여 전송한다(단계 40).The PC 10 transmits the stream according to the request of the PVR 20 to the PVR 20 through the wireless Ethernet adapter 16 (step 40).

PVR(20)은 PC(10)로부터 제공되는 해당 스트림을 무선 이더넷 액세스 포인트(26)를 통하여 수신하고 DTV 디코더(24)를 이용하여 디코딩하여 HDTV로 제공함으로써 HDTV가 해당 프로그램에 대응하는 고화질의 영상을 디스플레이하도록 한다(단계 42).The PVR 20 receives the corresponding stream provided from the PC 10 through the wireless Ethernet access point 26, decodes it using the DTV decoder 24, and provides the stream to the HDTV. Display (step 42).

상술한 본 발명에 따른 PVR(20)은 지상파 DTV(ATSC) 신호를 통하여 제공받은 방송신호를 이용하여 HDD(30) 및 DVD 드라이브(32)에 저장할 수 있고 이를 타임 시프팅(time-shifting), 편집기능 등에 응용할 수 있다. 그리고 PC(10) 네트웍 상에연계된 다양한 멀티미디어 데이터와 해당 EPG 정보를 무선으로 전송받아 DTV 지상파 방송신호처럼 HDD(30)에 저장 및 재생하여 타임 시프팅 기능을 이용할 수 있고 다양한 부가 편집기능을 이용하여 DVD 드라이브(32)에 저장할 수 있다. 또한, 기존 PC의 강력한 프로세싱 능력을 이용하고 PC 기반의 네트웍 데이터베이스를 PVR에 연계하여 가정 내에서 통합적인 홈 네트웍(home network)을 구성할 수 있다. 이러한 네트웍을 기반으로 하여 PVR은 가정내에서 공중파 방송신호 뿐만아니라 PC 망에 산재된 다양한 콘텐츠를 활용하여 스트림 플레이어(stream player)를 할 수 있다.The PVR 20 according to the present invention may be stored in the HDD 30 and the DVD drive 32 using a broadcast signal provided through a terrestrial DTV (ATSC) signal, and may be time-shifted, It can be applied to an editing function. In addition, various multimedia data and corresponding EPG information connected on the PC 10 network are wirelessly transmitted and stored and reproduced on the HDD 30 as a DTV terrestrial broadcast signal to use the time shifting function and various additional editing functions.
