Problems solved by technology

However, the DVD player described above was manufactured for reproduction in televisions with analog inputs, without careful consideration of digital televisions
Therefore, even if a DVD player and a digital TV are connected through IEEE1394, it is difficult to use a digital TV to reproduce the current standard DVD information.

Embodiment Construction

[0029] see figure 2 , in the device for transmitting information through a network according to a preferred embodiment of the present invention, a digital versatile disk (DVD) playback device serving as a server (first device) is connected through a digital interface (such as an IEEE 1394 cable) and a digital television (TV) as a client (second device).

[0030] exist figure 2 Among them, the composition and operation of the spindle motor 204, the pick-up unit 206, the radio frequency amplifier (RF-AMF) 208, the servo controller 214, the digital signal processor (DSP) 210, and the buffer 212 are the same as figure 1 These parts are the same in , so their descriptions are omitted.

[0031]If the data output from the DSP 210 is scrambled for the purpose of preventing digital copying, a content scrambling system (CSS) decoder 216 descrambles the data provided from the DSP 210 . The descrambling stream is the program stream specified by the MPEG standard, including a video pa...

Abstract

An apparatus for transmitting information via a network, and a method are provided. The information transmission apparatus includes a first device having a transport format converter for receiving user interface data in put via a user interface, the user interface for commanding and controlling the first device, and for converting information into a transport format for transmission, a second device having a display unit, the display unit for displaying the user interface or commanding and controlling the first device, and a physical layer for linkig the first and second devices for communications. The IEEE 1394 interface is adopted as the physical layer, so that the second device can control the operation of a digital versatile disc player as the first device, and interfacing between devices using the MPEG-2 transport stream becomes easier.

Description

[0001] This application is a divisional application with the application number 03101496.8, the application date is June 19, 1999, and the invention name is "equipment for transmitting / receiving information through a network including synchronous and asynchronous channels". technical field [0002] The present invention relates to the transfer of digital data, and more particularly, the present invention relates to an apparatus and method for transferring information from a Digital Versatile Disc (DVD) over a network to a device which may be a user interface display, such a device and method The display device is allowed to control the DVD information. Background technique [0003] Typically, a digital versatile disc playback device decodes a bit stream read from a disc using a video decoder built into it, and converts the bit stream read from a disc using a scheme such as the National Television System Committee (NTSC) standard. The decoded video signal is converted to an a...
