Since the network is becoming wireless and the demand for high-capacity multimedia data transmission is increasing, research on effective transmission method in a wireless network environment is required.

In addition, there is a growing demand for wireless transmission of high-quality video such as DVD (Digital Video Disk) video and HDTV (High Definition Television) video between various home devices.

At present, a task group of IEEE 802.15.3c is promoting a technical standard for transmitting a large amount of data in a wireless home network. This standard, called mmWave (Millimeter Wave), uses radio waves with physical wavelengths in millimeters (ie, radio waves with frequencies from 30 GHz to 300 GHz) for large data transmissions.

In particular, the ultra-high speed wireless transmission technology of the 60 GHz band may exceed the limitations of the conventional wireless transmission technology.

There is no technology capable of compressing and lossless full HD video at the current technology level.In addition, the millimeter wave band uses ultra-wide bandwidth, and it has strong straightness in addition to high-efficiency data rate, so it is very resistant to surrounding interference, and has excellent security and frequency reuse. It has the advantage of easy application of technology due to its ease of use, and it is possible to miniaturize and reduce the weight of various devices due to the short wavelength, thus supporting the recent home network and high-definition multimedia transmission and application service as the optimal frequency band for high-speed wireless communication. Is a suitable technique.

In order to transmit HD-quality high-definition video, which is the mainstream of the current video market, using a conventional wireless LAN or UWB communication, the transmission speed is a problem compared to the data size of the video. Should be reproduced.

Currently, the transmission of full HD content uses a high-definition multimedia interface (HDMI), which is mainly a wired interface, and uses UWB technology to transmit full HD content wirelessly, but the data transmission speed is within 10m. Is only 480Mbps, which is caused by compression transmission, causing problems in high definition.

This technology uses collaborative MIMO with peripheral devices to transmit data to a receiving group through a band below 5GHz.

This does not disclose a method that can selectively utilize the peripheral devices had a inconvenience in use.

In addition, only one transmitting device can communicate with each receiving device, and thus there is no technology for communication relaying of a plurality of receiving devices using a multi-channel.

1 is a conceptual diagram briefly showing an ultrafast wireless relay system for a millimeter wave band according to an embodiment of the present invention.

As shown in FIG. 1, the system of the present invention includes an input device 300, a transmitting means 100, a relay means 200, and a receiving means 400.

In the 60GHz millimeter frequency band, which is the wireless technology applied in the present invention, it provides a transmission speed of at least 6 times higher than that of the prior art, so that a high-definition high-definition screen transmission is possible without the use of any compression technology when transmitting full HD quality high-definition screen. Therefore, when applying full HD quality high-definition transmission transmission technology to general data transmission of portable multimedia devices, it takes 1 hour and 30 minutes to download one CD of 650MB capacity when using Bluetooth technology that is currently spreading. It is a high speed communication method that can be downloaded in 1-2 seconds.

Meanwhile, as shown in FIG. 1, the present invention provides a high-definition video transmission channel wirelessly in place of a conventional wired HDMI cable when video devices existing in homes and offices are connected to a high-definition video output device.

By providing as described above, it is possible to increase connectivity and user's dignity beyond the complicated wired method.

UWB technology is used to transmit full HD content wirelessly, but data transmission speed is only 480Mbps at short range within 10m.

However, in the case of the present invention, since the transmission technology of 60 GHz is used, the transmission speed is 4 Gbps to provide uncompressed transmission, thereby enabling high quality implementation.

Figure 2 is a block diagram of the transmission means of the ultra-high speed wireless relay system for millimeter wave band according to an embodiment of the present invention.

As shown in Figure 2, the transmission means of the ultra-fast wireless relay system for the millimeter wave band of the present invention,

A multiplexing packet processor 110 for extracting multimedia data transmitted from the input apparatus 300 and generating the multiplexed packet;

A receiving means group generating unit 120 for generating a group of receiving means capable of receiving multimedia data over a 60 GHz millimeter frequency band;

A sync frame allocator 130 for allocating a sync frame to maintain sync with the receiving means;

A channel changing unit 140 for changing a channel if it is impossible to maintain synchronization with the receiving means 400 which is turned on by the relay means;

A receiving means matching section 150 for matching the multiplexed packet information generated by the multiplexing packet processing section with the synchronous receiving means;

And a transmitting wireless chipset 160 for transmitting the multiplexed packet matched by the receiving means matching unit to the corresponding receiving means through the 60 GHz millimeter frequency band.

The transmission means decodes a Transition-Minimized Differential Signaling (TMDS) coded signal sent from an input device connected to an HDMI input terminal by a transmission AV processor and decodes a video / audio signal by processing of the multiplex packet processing unit 110. After extraction, the data is sent to the multiplexed packet and then sent to the 60GHz transmission wireless chipset unit 160.

The receiving means of the present invention demultiplexes a wirelessly transmitted multiplexed packet by a demultiplexing packet processor, extracts a TMDS signal as a video / audio signal through a receiving AV processor, and is connected to the receiving means through an HDMI output terminal. It is transmitted to the playback device for playback.

Meanwhile, the receiving means group generating unit 120 generates a group of receiving means capable of receiving multimedia data through the 60 GHz millimeter frequency band.

That is, a group of receiving means is generated, and a device is detected to identify a receiving means in a communicable state, and if the receiving means is in a communicable state, it may form a transmitting group with receiving means capable of short range communication. Can be.

At this time, the receiving means group generation unit is configured to include a CEC controller for transmitting the device discovery information on the CC network to the multiplex packet processing unit.

At this time, the CEC controller has a CEC message which is not processed as an input, and reorganizes information in response to an AVC device control message.

Accordingly, input may be automatically selected by the user or by using the CEC function, and the input devices may be connected to devices having the CEC function and various devices not including the CEC function.

In addition, a device having a CEC function performs a CEC routing function to deliver a CEC message sent from a source or playback devices.

The playback device may generally be a TV or a recorder device, a projector, or the like.

The sync frame allocator 130 allocates a sync frame to maintain sync with the receiving means.

The transmitting means periodically transmits a synchronization signal to receiving means belonging to a predetermined radius to maintain synchronization with one or more receiving means.

While the synchronization is maintained as described above, the transmitting means and the receiving means may transmit and receive multimedia data such as voice, video, and text.

The relay means according to the present invention may maintain synchronization with the above-mentioned transmission means, and may transmit a synchronization signal different from the above-mentioned transmission means to the reception means.

That is, when the receiving means loses synchronization with the transmitting means because the distance from the transmitting means is far from the transmitting means, the relay means according to the present invention causes the transmitting means to change to another channel when the communication means is in a one-to-one communication. Will keep you motivated.

To this end, the channel changing unit 140 is configured, and if it is impossible to maintain synchronization with the receiving means 400 operating by the relay means, the channel is changed.

That is, conventionally, only one receiving device is kept synchronized to one transmitting device, so when one device transmits data, the other receiving device is in a standby state, and thus the plurality of receiving devices cannot simultaneously perform bidirectional communication. Since the channel is changed through, a plurality of communication can be provided.

In addition, the receiving means matching unit 150 matches the multiplexing packet information generated by the multiplexing packet processing unit with the synchronous receiving means.

That is, the on state of the receiving means is checked, and then multiplexed packet information is matched and provided.

The transmitting wireless chipset unit 160 transmits the multiplexed packet matched by the receiving unit matching unit to the corresponding receiving unit through the 60 GHz band millimeter frequency band.

In order for the multiplexed packet processing unit to operate properly on the network, an initialization process must be performed by the initialization processing unit.

This consists of three states of movement.

The transmit wireless chipset section starts in the "reset" state, which initializes all internal hardware and software.

Once the above process is completed, the process enters the "config" state. In this state, wireless transmission is not available, but the wireless interface must be available before the radio is operated.

Finding a playback device is divided into three parts.

That is, in order to start device discovery, the transmitting wireless chipset unit detects a remote playback device through a mechanism provided by WiHD and informs the input device as a host that there is a change in network status.

The host then determines whether a request for information from the remote playback device is required and if the host needs a feature request, the response step needs to receive the requested information.

The above processes are processed by the receiving means group generating unit, the function of which discovers the remote playback apparatus, informs the input apparatus that there is a change in the state of the network, determines whether a request for information from the playback apparatus is required, and the input apparatus. When a function request is made, it receives the requested information.

At this time, the initialization processing unit 161 performs initialization so that the multiplexing packet processing unit operates on the network.

After that, if the device fails to detect the playback device, it notifies the host with the "Feature Abort" command. If the host receives the "Feature Abort" command for the specific device, it returns a status variable and returns to the "IDLE" state for that device. I have to go.

The "Capabilities Request" command can never be sent to the host and it is not necessary to request information from the host.

This is because this information is already transmitted to the wireless chip set for transmission in the initialization process. For this reason, the transmitting wireless chipset unit will respond regardless of the host when the remote playback apparatus requests information.

The transmitting wireless chipset unit needs some signal to start device discovery. The transmitting wireless chipset unit detects a playback device in real time through WiHD, and when a new device is found or disconnected from a device that has been previously connected to a network, The chipset section informs the host via the index bitmap table residing in the control register space.

Next, the sensing step of the receiving means group generation unit will be described as follows.

When the transmitting wireless chipset finds a new WiHD device, it assigns an index value for that device and writes this information to the control register space for the host to use.

An interrupt occurs when the transmitting wireless chipset accesses the register, and the interrupt is released when the update to the device is completed.

The host is granted only read access to this register, so the host cannot change the contents of the register.

When the host detects a change in the device list, the host needs to make a decision as to whether the device is new.

The final step in device detection is to check the list of devices read by the host.

This is simple but very important and does not update the device list again until the host has confirmed receipt of the existing list.

After the device detection step is finished, the host must determine whether the devices on the wireless network are new or not.

The host can then choose whether or not to send an information request message to the new device to obtain additional information about the remote device. The request can be made using the TX packet register.

There is an information response unit that receives the information request message from the host and obtains the requested information from the playback apparatus.

When the information response unit 162 obtains information from the network, the information response unit 162 creates an RX message in a register, and the response message follows the WiHD format.

The unique index value for each device is included in the message, followed by the requested information about the device.

This message is written to the receive register and the host is notified that the message is ready at the same time by generating an interrupt and setting the "RX READY" bit.

The contents of the receive register must be read before the "RX READY" bit is cleared.

With this bit set, it maintains the contents of the receive register.

However, after this bit is cleared, the contents of the receive register can be changed.

In order to properly form the streaming video / data transmission between the transmitting means and the receiving means, the connection order must be clearly formed.

In this case, the protocol must match the WiHD underlying this interface and all connection control operations will use the device index generated during device discovery.

That is, the above process is performed by the connection controller, and its function is to connect the corresponding playback device to the input device using device index values for streaming video and data transmission.

The connection control unit 163 waits until an event occurs and is activated by a local event (the administrator initiates the connection of the remote playback device) or by a remote connection request.

Once the event occurs, the information between the transmitting means and the receiving means for establishing the proper connection begins to move.

When connected by the connection controller, the device controller enables high-level control through the device on the WiHD initialized by the devices on the network.

Device control messages are sent or received on RX / TX packet media, such as those used in device discovery or connection control.

The CEC controller has an unprocessed CEC message and reorganizes the information in response to the AVC device control message.

After message conversion, the baseband control API operates the converted AVC message to the allocated transmission wireless chipset unit.

Since the CEC controller needs to pass the device discovery information of the devices on the CEC network to the transmitting wireless chipset section, it is necessary to be able to assign a device index to each CEC device so that the message can be properly converted to an AVC message. It is required.

Device index assignment is given by the device controller 164 of the WiHD radio chipset section.

The millimeter wave wireless communication described in the present invention is expected to be widely used in digital video devices having high utility in home networks and high transmission rate of video information between devices because of the wideband transmission and miniaturization of components. .

In addition to being able to obtain the high data rate, the linearity is strong and thus has no influence on surrounding interference, and has excellent security and easy frequency reuse.

Figure 3 is a block diagram of the relay means of the ultra-high speed wireless relay system for millimeter wave band according to an embodiment of the present invention.

As shown in Figure 3, the relay means 200,

A relay synchronous frame assignment unit 210 for maintaining synchronization with transmission means corresponding to the synchronization frame assigned by the synchronization frame assignment unit;

An on-state receiving group unit 220 which checks the receiving means that is being operated on among the receiving means generated by the receiving means group generating unit;

A reception means synchronization holding unit 230 for maintaining synchronization with the reception means in a synchronization frame allocated by the relay synchronization frame assignment unit;

A synchronization holding state checking unit 240 for checking a synchronization holding state at the time of relaying with the receiving unit;

And a channel change signal transmitter 250 for transmitting a channel change signal to the transmission means when it is checked that synchronization cannot be maintained by the synchronization hold state check unit.

That is, the relay synchronous frame allocator 210 allocates the relay synchronous frame to maintain synchronization with the transmission means corresponding to the sync frame allocated by the sync frame allocator.

When the relay means uses the same frequency set as the transmission means, the relay means stores the frequency set information received from the transmission means.

The on-state receiving group check unit 220 checks the receiving means which are on-operated among the receiving means generated by the receiving means group generating unit, and the receiving means synchronization maintaining unit 230 is configured to relay synchronizing frame allocation unit. The synchronization frame is allocated to maintain synchronization with the receiving means.

The synchronization maintaining state checking unit 240 checks the synchronization maintaining state at the time of relaying with the receiving unit.

This is because it is necessary to resynchronize by changing the frequency set of the corresponding synchronization because the communication may be inactive due to an inability to communicate or an unexpected problem during synchronization.

At this time, if the channel change signal transmitter 250 checks that synchronization cannot be maintained by the synchronization holding state check unit, the channel change signal transmitter 250 transmits a channel change signal to the transmission means to request a change in the frequency set for synchronization.

For example, when the reception means loses synchronization with the relay means, it is necessary to change the synchronization frame transmitted by the relay means.

At this time, the relay means is in a state of being kept in synchronization with the transmitting means, so that the channel change request signal can be transmitted to the transmitting means.

That is, as shown in FIG. 4, if synchronization occurs with the receiving means while maintaining synchronization with one channel, the relay means and the receiving means communicate with two channels after changing to two channels.

Through the configuration and operation described above, it is possible to relay the communication of a plurality of various receiving means without compressing the full HD video in real time, so that even if there are a plurality of receiving means, multi-relay is possible through efficient relaying. At the same time, it will provide an effect that can satisfy the consumer's video experience.

It will be appreciated by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. Therefore, the above-described embodiments are to be understood as illustrative in all respects and not restrictive.
