DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital video distribution apparatus, a method, and a medium on which a program is recorded, which uses both a narrow band and a wide band transmission path. The present invention relates to the enjoyment of high-definition digital broadcast video such as MPEG-2 using a transmission path in a home storage device in a broadband environment.

[0002]

2. Description of the Related Art Conventionally, a television broadcast receiving system includes:
There are a method of receiving radio waves with an antenna and a method of receiving signals via a cable.

[0003] The receiving method via an antenna is widely used in ordinary households.

In this system, when a television (receiver) is turned on, radio waves received via an antenna enter the receiver. At this time, the data is distributed via a cable indoors.

[0005] Recording of received broadcasts on a tape medium is also performed by connecting the broadcast to a storage device. Further, in addition to the tape medium, storage in a storage device of a computer terminal and an electronic medium are also performed.

On the other hand, the transmission path of the receiving system via a cable is a coaxial cable, which is physically connected.
It is often used in environments where radio waves are difficult to receive.

[0007]

However, in the above-mentioned conventional television broadcast receiving system, the apparatus is used in a portable or car-mounted state because the apparatus is downsized in a mobile environment. Therefore, it is difficult to incorporate a tape medium storage device. In addition, electronic storage media have been miniaturized, and the storage density of storage devices has been increasing. However, since the amount of video information is enormous with respect to the storage capacity at the current recording density, storage is Can not do it.

[0008] On the other hand, conventional transmission lines for television broadcasting have a wide band and a dedicated cable line is used, but a general telephone line or a narrow band transmission line such as a portable telephone is used. It cannot be received.

More specifically, there are limitations on the recording density and the recording capacity of the storage device and the bandwidth of the receiving environment. Approximately 1.7 GB of digital broadcasting with 4 Mbps of information for 1 hour
Therefore, a saturation state due to accumulation of digital broadcast video in a storage device and a storage medium of about several MB is inevitable.

[0010] Even on one transmission line, an information amount of several Mbps cannot be received for a reception band of several Kbps.

Therefore, the present invention provides an information conversion device using:
By performing conversion according to the bandwidth of the reception environment, it is possible to use both narrow-band and wide-band transmission lines, and display and store high-definition digital broadcast video on portable terminals and home storage devices linked to portable terminals.
