Problems solved by technology

When using, you need to connect the DVD recorder to the corresponding terminal of the receiver to work normally, which is very inconvenient to use
At the same time, the terminals are easily damaged by repeated plugging and unplugging, which reduces the reliability of signal transmission
Moreover, the playback of a single DVD recorder can only be received by a single display device, and the external peripherals cannot be expanded.

Embodiment Construction

[0009] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0010] Figure 1 is a schematic diagram of the internal circuit of the DVD recorder capable of wireless transmission of audio and video signals according to the present invention, including the internal core electronic circuit of the DVD recorder and the UWB module. The UWB module is controlled by a transceiver, a baseband processor and a media access control. The transceiver is connected in sequence, the transceiver is connected with the antenna, and the internal core electronic circuit system bus of the DVD burner is connected with the media access controller in the UWB module.

[0011] In the UWB module, the transceiver and baseband processor together form the lowest layer of UWB, which becomes the physical layer of UWB, responsible for radio frequency signal transmission and reception and baseband signal processing; the media access controller (MAC) acts as ...

Abstract

The invention discloses a DVD-RW that could realize radio video frequency signal wireless transferring. It includes inner core electric circuit and UWB module. The UWB module is made up of receiver, base band processor, and medium access controller. Receiver connects to antenna, and the system bus of DVD-RW inner core electric circuit connects to the medium access controller in UWB module. The invention uses UWB method to take wireless transmitting for audio video frequency signal. It could realize single DVD play on plural display devices.

Description

Technical field [0001] The invention relates to a DVD product, and more specifically, to a DVD burner capable of realizing wireless transmission of audio and video signals. Background technique [0002] A cable connection is used between the existing DVD burner and the multimedia receiver. When using, it is necessary to connect the DVD burner to the corresponding terminal of the receiver to work normally, which is very inconvenient to use. At the same time, the terminals are easily damaged after multiple insertions and unplugging, which reduces the reliability of the transmission signal. Moreover, the playback of a single DVD burner can only be received by a single display device, and peripherals cannot be expanded. Summary of the invention [0003] The present invention is to overcome the shortcomings in the prior art and provide a DVD burner capable of wireless transmission of audio and video signals and convenient to use. [0004] The present invention is realized through the...
