The present invention relates to an HDD removable PVR, and more particularly, a part of the case is formed as an opening to open a space for mounting the HDD inside the case, so that various storage media may be used depending on the failure, performance degradation, or desired capacity of the HDD. The present invention relates to an HDD removable PVR that can be detached and mounted.

Digital TV has made it possible to enjoy high-definition video and high-quality sound.Personal video recorders (VVRs) using hard disks, followed by VCRs (video cassette recorders), which have been spotlighted as storage devices in the past of analog TV, It is getting popular as a digital image storage medium.

Unlike a VCR that stores video signals on magnetic tape, a PVR is a new concept of digital recording device that records and plays back information on a hard disk.It uses a built-in HDD in a set-top box or television body to provide a certain amount of time without a VCR. It is a next generation recording device that can record broadcast programs.

The basic function is not much different from the existing VCR in that the program is stored in the broadcasting station, but the information is recorded on the hard disk and played back using a file playback method such as a computer, the central processing unit (CPU), The difference is that a memory chip containing an operating system and playback software and a large hard disk are embedded.

It consists of a television tuner, storage / playback software, network devices and HDDs, which combine HDDs used in computers to convert TV programs into digital signals for storage and playback on HDDs, up to 30 hours of broadcast. The quantity is stored and a plurality of programs can be recorded at the same time.

In addition, scheduled recording is possible by receiving the latest broadcast schedule through a network device, and various services can be provided through the Internet.When a channel is selected, a signal currently broadcasted on the HDD is automatically stored and played back digitally. When the broadcast signal is continuously stored, the program can be continuously watched even after being paused, and various viewing is possible according to the user's intention such as low speed and high speed playback.

Therefore, in the case of a conventional VCR, the image quality is deteriorated when a plurality of recordings are recorded on the same tape, and the same problem occurs when recording and storing for a long time, and the original image cannot be completely restored and displayed. Because it requires a lot of time to search for the desired video, the PVR, which is a recording device using a hard disk, is stored digitally, so that the image quality before and after storage is the same and there is almost no deterioration in image quality even if used several times. As a result, access to data at a predetermined position is easy, so that data of a desired place can be searched faster than that of a conventional VCR.

The digital storage / playback PVR is an application device in which a storage device such as a hard disk driver (HDD) is combined with a digital TV / set top box (DTV / STB). For example, a digital broadcast input based on MPEG-2 or The purpose is to store analog (NTSC) broadcasts encoded in MPEG-2 on a digital storage medium.

To do this, unlike a conventional system decoder which does not consider storage, a basic structure for storing a stream input at the time of recording in a medium such as a hard disk and reading the stream stored in a medium such as a hard disk at the time of reproduction and transmitting it to the input of the decoder. Should be equipped.

Here, the system decoder refers to a stream that conforms to a standard such as ISO / IEC 13818-1 (information technology-generic coding of moving pictures and associated audio information system), which is a standard for time-division and transmission of a plurality of sound, video, and other data. As a decoder for decoding and obtaining a configuration stream, this means a kind of synchronization connector device.

PVR can be used to encode current analog TV broadcasting into compressed video data such as MPEG and record it on hard disk. Especially in the case of digital TV, a plurality of virtual channels exist in one channel to transmit several programs. As a result, the demand for recording of a large number of programs is inevitably increased compared to the conventional analog TV environment.

In case of ATSC, which is a digital TV standard, HD-quality high-definition programs use 19.4Mbps of data allocated to one channel to transmit a single program. It can be transmitted through, which means that a plurality of programs can be simultaneously viewed even in a general receiver having one tuner and a demodulator.

In order for a PVR user to record multiple virtual channels, programs coming through each virtual channel must be processed by the system decoder, and a device for storing them on the hard disk is required. The performance of the hard disk is due to its mechanical characteristics. Very limited.

Hard disks currently used for home use generally have slower disk rotation and data transfer speeds than those used in ordinary PCs due to noise and heat problems, and provide the performance to reliably record and play a single HD program. have.

However, considering only the amount of data, the amount of data of one HD program and the plurality of SD programs are similar, so there should be no problem. When recording a single program, the storage location is used when recording multiple programs while using a continuous space. Since the data is changed from time to time, the data transfer efficiency is generally lowered due to the time required for the head of the disk to move. Therefore, when a plurality of programs are recorded, a stable service cannot be provided unless the data transfer efficiency is maximized.

In addition, the conventional PVR is screwed into the bracket to the assembly structure of the method of fixing it directly to the case and body of the product, so it is difficult to upgrade the replacement method even if the playback speed and storage amount of the HDD is increased, for example, 20G, Despite the fact that various types of storage spaces and rotation speeds (rpm) such as 40G, 60G and 80G are available on the market, not only can the HDD be replaced freely according to the user's needs and needs, but also the HDD is damaged by external shocks and self-deterioration. Even if the performance is degraded or damaged, there is a problem that maintenance is difficult because only a specialist can visit the service point to repair and replace it.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a HDD removable PVR in which a storage device of a PVR such as an HDD can be freely received from the outside.
