CN101370021A - DVD recorder with network function - Google Patents

Abstract

The invention relates to a DVD optical disc recorder with network function. A network interface is provided at DVD optical disc recorder and bidirectionally connected with Mpeg2 codec in optical disc recorder; FLASH memory stores network cop protection program, and receives network data from network interface; when network protected content is needed to copy, content copy and protection is performed by CGMS algorithm, and optical disc is burned at DVD recorder cassette through ATAPI interface. It is characterized in that protected content of network can be directly recorded, and the recorded optical disc can not be edited in computer or copied to other optical discs.

Description

The DVD CD writer of band network function

Technical field

The present invention relates to a kind of DVD CD writer, particularly a kind of DVD CD writer with network function.

Technical background

Along with Digital Electronic Technique and rapid development of network, network has almost been come into most of common people's family, selects computer to see news on network, sees stock, sees a film and the above content of imprinting, all be accustomed to very much, but computer costs an arm and a leg.If effectively DVD CD and network are combined; it also is effective utilizing the imprinting function duplicate network content of DVD burner; be inexpensive; but the Web content that has is protected content in order not illegally copy network, therefore must make the DVD CD writer have the function of Copy Protection.

Summary of the invention

At the demand in market, the present invention proposes one and on the DVD CD writer network interface is housed, and with the film form Web content is burnt in the DVD CD easily.Concrete technical scheme is: the DVD CD writer of band network function is characterized in that: a network interface is housed, with two-way connection of Mpeg2 codec in the DVD burner on the DVD CD writer.Network-copy defence program step is,

The first step: CD writer proposes network access request;

Second step: download of network data is saved in the buffer;

The 3rd step: generate result screen and the video output browsed;

The 4th step: enter next step as storage, browse picture otherwise return;

The 5th step: as Copy Protection, adopt the CGMS algorithm to carry out the content Copy Protection and be written to during DVD imprints CDs, otherwise directly be written to during DVD imprints CDs by the ATAPI interface by the ATAPI interface.

Characteristics of the present invention are, can be burnt to Web content in the DVD CD with the film form easily at any time, cheaply easily enter most of common people's family, and this CD can not be edited on computers and can not copy on other CD simultaneously.

Embodiment

As shown in Figure 1, Mpeg2 encoder and a buffer, a FLASH flash memories, a rf tv tuner, composite video input and output, super video input and output, ATAPI interface (DVD CD burning movement) two-way a connection, simultaneously the Mpeg2 encoder also with the output of aberration video, HDMi output, LCDs, constitute a DVD CD writer.Mpeg2 is connected with network interface is two-way simultaneously, can control and accepts data from network interface.Contain the program that codec will use in the FLASH flash memories, the data that codec will receive from network interface change into the DVD data of optical disk, by the ATAPI interface, are burnt in the DVD CD.

Network-copy defence program step is as shown in Figure 2,

The first step: CD writer proposes network access request;

Second step: download of network data is saved in the buffer;

The 3rd step: generate result screen and the video output browsed;

The 4th step: enter next step as storage, browse picture otherwise return;

The 5th step: as Copy Protection, adopt the CGMS algorithm to carry out the content Copy Protection and be written to during DVD imprints CDs, otherwise directly be written to during DVD imprints CDs by the ATAPI interface by the ATAPI interface.

Claims (2)

1. DVD CD with network function CD writer is characterized in that: a network interface is housed, with two-way connection of Mpeg2 codec in the DVD burner on the DVD CD writer.

2. the DVD CD of band network function as claimed in claim 1 is carved CD writer, it is characterized in that: network-copy defence program step is,

The first step: CD writer proposes network access request;

Second step: download of network data is saved in the buffer;

The 3rd step: generate result screen and the video output browsed;

The 4th step: enter next step as storage, browse picture otherwise return;

The 5th step: as Copy Protection, adopt the CGMS algorithm to carry out the content Copy Protection and be written to during DVD imprints CDs, otherwise directly be written to during DVD imprints CDs by the ATAPI interface by the ATAPI interface.
