The receiving terminal 300 is connected to an individual multimedia contents broadcasting equipment 100a as it requests a connection to an individual multimedia contents broadcasting equipment 100a through a radio network formed by means of an individual multimedia contents broadcasting is equipment 100a depending on a user's operation and receives a private IP.
The receiving terminal 300 is capable of receiving and playing back the broadcast contents from the individual multimedia contents broadcasting equipment 100a.
The receiving terminal 300 might be a mobile communication terminal having an input unit such as an operation unit 104a, an output unit such as a speaker 104d and a LCD 104e, and a radio communication unit 102 for a data receiving and transmission through the radio network or might be a portable individual information communication instrument such as a PDA, a palm top computer, a UMPC, a navigation device, a portable game unit or the like. Here, the radio network according to the present invention is constructed to perform a radio data communication based on the IEEE 802.11 protocol. So, there is provided a radio communication unit 102 which supports a data communication based on the IEEE 802.11 protocol. The radio network according to the present invention might be configured to use various universal radio data communication protocols except for the IEEE 802.11 if necessary. The construction and functions of the receiving terminal 300 will be described later with reference to
The individual multimedia contents broadcasting equipment 100a lo creates and stores broadcast multimedia contents depending on a broadcaster's operation and allocates a private IP depending on a connection request of the receiving terminal 300 and forms a radio network and transmits a broadcast multimedia content selected by means of a broadcaster's operation. The individual multimedia contents broadcasting equipment 100a might be equipped with an input unit such as an operation unit 104a, a microphone 104b, a camera 104c or something, an output unit such as a speaker 104d, a LCD 104e or something, a mobile communication terminal having a radio communication unit 102 for a data receiving and transmission through a radio network, and an individual information communication instrument such as a PDA, a palm top computer, a UMPC, a navigation device, a portable game unit or something. The functions and constructions of the individual multimedia contents broadcast equipment 100a will be described with reference to
Here, the radio network created and maintained by means of the individual multimedia contents broadcasting equipment 100a is designed to use an ISM (Industrial, Science and Medical) radio frequency band or a U-NII 5 GHz radio frequency band. The ISM radio frequency band is a frequency band allocated by the FCC for the use in industry, a science and a medical field. 902.about.928 MHz, 2.4 G.about.2.4835 GHz and 5.725 GHz.about.5.835 GHz frequency bands are set for the ISM bands. These frequency bands are not needed to have ant permission for a frequency allocation. The output of the equipment which uses the above frequency bands is 17 dBm/50 mW. The U-NII 5 GHz radio frequency band is a frequency band used in the IEEE 802.11a and HIPERLAN/2 which also does not need any permission for a frequency Lo allocation.
In the present invention, 802.11a, 802.11b or 802.11g might be used or properly combined for a LAN radio communication. The 802.11a, 802.11b and 802.11g are the protocols for a radio LAN developed by the IEEE work group. The above three protocols use CSMA/CA which is an Ethernet protocol. The 802.11b provides a rate of 11 Mbps per second, whereas the latest 802.11g provides a relatively shorter distance communication at a rate of 54 Mbps in maximum. Since the 802.11g works in a 2.4 GHz band like 802.11b, there is compatibility between the above two protocols. The modulation method used in 802.11 is traditionally PSK, but the modulation applied in 802.11b provides a faster data transmission rate, and uses CCK which is not interfered with multiplexed transmission passages. The 802.11a is generally used in a radio ATM system, namely in an access hub. The 802.11a is applied in a radio frequency bandwidth of 5 GHz-6 GHz. The 802.11a uses a modulation method which is called an OFDM for a data transmission rate up to 54 Mbps in maximum.
In case of 5 GHz band, since it is a relatively higher frequency, it is not proper that other small compact sized radio devices might compete with one another for frequencies. The IEEE 802.11a has much less interferences by means of other devices as compared to the IEEE 802.11b and advantageously supports a faster transmission rate of 54 Mbps. It is preferred that the radio network according to the present invention is configured in an independent network for a personal broadcasting service provided using a private IP through a DHCP function of the individual multimedia contents broadcasting equipment 100a.
It is disadvantageous that the IEEE 802.11a, IEEE 802.11b, and IEEE 802.11g might be used only for the LAN radio communication. So as to overcome the above disadvantages, the individual multimedia contents broadcasting equipment according to the present invention might be further equipped with an individual multimedia contents relay broadcasting equipment 100b. The individual multimedia contents relay broadcasting equipment 100b is configured in the same manner as the individual multimedia contents broadcasting equipment 100a. A private IP is allocated from the individual multimedia contents broadcasting equipment 100a in a radio communication radius of the individual multimedia contents broadcasting equipment 100a, and the individual broadcast received depending on a request of the receiving terminal 300c in a relay radio network range, which requests a received individual broadcast viewing, is relayed. Namely, the individual multimedia contents broadcasting system according to the present invention can overcome the problems of the radio data communication radius by using the individual multimedia contents relay broadcasting equipment 100b, so it is possible to watch an individual broadcast from a relatively farther distance.
As shown in
The input and output unit 104 includes an input part and an output part. The input part is formed of at least one among an operation unit 104a for receiving a control signal based on a broadcaster's operation, a microphone 104b for receiving a sound data, and a camera 104c for receiving a video data. The output part is formed of at least one between a speaker 104d for is outputting a sound data, a LCD 104e for outputting a video data and something. Here, the operation unit 104a represents an input device such as a keypad, a keyboard, a mouse, a touch screen or something. The microphone 104b and the camera 104c might be formed of a microphone 104b and a camera 104c provided in the individual multimedia contents broadcasting equipment 100a or might be formed of an external microphone 104b and a camera 104c connected through an interface part such as a USB port. The input and output unit 104 is configured by using a known art. So, the detailed descriptions of the same will be omitted.
The individual broadcast process unit 103 creates and stores broadcast contents using a data inputted through an input unit and provides a receiving terminal, which requests a connection, with a private IP for thereby connecting through a radio network and transmits broadcast contents to the receiving terminal connected. More preferably, the individual broadcast process unit 103 according to the present invention includes a broadcast module 103c, a storing device 103b and a controller 103a.
The broadcast module 103c creates and stores broadcast contents using a data inputted through an input unit depending on a broadcaster's operation and provides a private IP to the receiving terminal 300 which requests a connection for thereby connecting through a radio network and transmits an individual multimedia content to the connected receiving terminal 300 based on a broadcaster's selection. At this time, the individual broadcasting multimedia contents broadcasted through the receiving terminal 300 according to the present invention might be a text data, a symbol data, a music data inputted through the microphone 104b, a sound data, an audio data, a video data inputted through the camera 104c, an image data, a photo data or a combination of the same.
The individual broadcasting multimedia contents according to the present invention might be an individual broadcasting multimedia content created in real time from the broadcasting module 103c depending on a broadcaster's operation, an individual broadcasting multimedia content stored in the storing device 103b, an individual broadcasting multimedia content created in real time, an individual broadcasting multimedia content stored in the storing device 103b or a combination of the same and might be transmitted. When a broadcaster selects a real time broadcast by operating the individual multimedia contents broadcasting equipment 100a, the individual multimedia contents broadcasting equipment 100a according to the present invention creates an individual broadcasting multimedia content using a sound data, an audio data, a text data and a video data inputted in real time from the input unit, and transmits in real time to the receiving terminal 300. When the broadcaster selects a recording broadcast, the individual broadcasting multimedia content previously created and stored in the storing device 103b is transmitted to the receiving terminal 300. When the broadcaster selects a combined content (for example, when a specific content previously created and stored in the storing device 103b is selected as a background image, and when it is combined with a motion image inputted in real time on the background image and it is broadcasted), the contents combined with the individual broadcasting multimedia contents created in real time and the individual broadcasting multimedia contents stored in the storing device 103b are transmitted to the receiving terminal 300.
The storing device 103b includes various programs used for driving the individual multimedia contents broadcasting equipment 100b and stores an individual broadcasting multimedia content created from the broadcasting module 103c depending on a broadcaster's selection. The storing device 103b might be formed of various universal storing devices such as a hard disk drive, a ram disk drive or something.
The controller 103a controls a broadcast module 103c, a storing device 103b, an input and output unit 104 and a radio communication unit 102 depending on a control signal inputted through the operation unit 104a, and creates an individual broadcasting multimedia content and performs an individual multimedia contents broadcasting.
The radio communication unit 102 forms a radio network and performs a data communication with the receiving terminal 300 connected through a radio network and is configured to substantially support the IEEE 802.11a, IEEE 802.11b, IEEE 802.11g, IEEE 802.11n which are selected depending on the needs in the individual multimedia contents broadcasting system according to the present invention.
As shown in
The individual broadcast process module 200 is a key module for performing an individual multimedia contents broadcasting according to the present invention and creates and stores a multimedia content using the data inputted from the input unit and allocates a private IP through a DHCP (Dynamic Host Configuration Protocol) to the receiving terminal which requested a connection and sets a connection or retrieves the provided private IP and disconnects the connection and transmits an individual broadcasting multimedia content to the connected receiving terminal 300 based on the broadcaster's selection. So as to perform the above operations, the individual broadcast process module 200 comprises a DHCP module 200a, a private IP management module 200b, an authentication module 200c, a playback tool management module 200d, a connection terminal management module 200e, and a content creation module 200f.
The content creation module 200f creates a text data and a symbol data inputted through the individual broadcasting multimedia content operation unit 104a using a data inputted through the input unit, a music data, a sound data and an audio data inputted through the microphone 104b, and a video data, an to image data and a photo data inputted through the camera 104c and combines the same. So as to perform the above operations, the content creation module 200f according to the present invention is configured to support a text/symbol input function, a music/sound encoding function, a photo/motion picture encoding function or something. It further supports a combining and encoding function for a mixed content creation. Here, the encoding codes might be selected from mp3, wma, jpg, asp, mpeg, xvid or something. An exclusive codec might be used.
The DHCP module 200a allocates a private IP through a DHCP function to the receiving terminal 300 connected, and sets a connection or retrieves the allocated private IP and disconnects the connection. Namely, the DHCP module 200a according to the present invention performs a DHCP server function and sets a private IP in the receiving terminal 300, which requested a connection in an individual broadcasting independent radio network, by using a private IP information stored in the private IP management module, so the individual broadcasting independent radio network might be configured, and the individual broadcasting might be watched.
The private IP management module 200b stores and manages a private IP information to be allocated to the receiving terminal 300, and a private IP information allocated to the current receiving terminal 300. The private IP information created and stored by the private IP management module 200b is referred by means of the DHCP module 200a, so a private IP to be allocated to the receiving terminal 300 is determined. When the private IP is allocated to the receiving terminal 300 or is retrieved, and the connection is disconnected, the above operation is updated in real time.
The playback tool management module 200d judges whether the content playback tool is installed or not in the connected receiving terminal 300. When it is not installed, the multimedia content playback tool stored in the storing device 103b is transmitted to the receiving terminal 300 and is automatically installed, so the multimedia contents can be played back. At this time, the multimedia content playback tool installed in the receiving terminal 300 is configured to decode the encoded multimedia data depending on the adapted encoding codec or a codec previously installed in the receiving terminal 300 might be used or a certain codec might be previously installed in the multimedia content playback tool.
When the broadcaster selects an authentication function, the authentication module 200c performs an authentication using terminal information, so that only the authenticated receiving terminal 300 can view an individual broadcast. So as to perform the above operations, the authentication module receives registration information from a new terminal (or user) who wants to view the individual broadcast, and creates an authentication information and stores in the storing device 103b, for thereby finishing a new registration. The authentication information stored in the storing device 103b is compared with the authentication information (terminal information or user information) received from the connected receiving terminal, so a needed authentication is performed. As a result, when the authentication is succeeded, the content receipt of the receiving terminal 300 is permitted, and when the authentication is failed, the private IP provided to the receiving terminal 300 is retrieved, and the connection is finished.
The connection terminal management module 200e monitors in real time connection information including at least one among the number of connected receiving terminals, a connection state, a radio communication sensitivity or something and displays the current connection information on the LCD 104e temporarily or periodically depending on the previously set information and provides to the broadcaster in real time. The real time connection information monitored by means of the connection terminal management module 200e is stored in the storing device 103b in a DB form. The connection terminal management module 200e extracts and provides connection information stored in the database when the broadcaster requests a connection data such as connection information of a certain time period or a specific time section or provides the broadcaster with a statistic data.
The individual multimedia contents broadcasting equipment 100b according to the present invention receives an allocation of the private IP from other individual multimedia contents broadcasting equipments 100a for thereby receiving the contents broadcasted by means of another individual multimedia contents broadcasting equipment 100a. So, the individual multimedia contents broadcasting equipment 100b according to the present invention performs a relay broadcast in a relay region where requests a receipt of the multimedia contents received from another individual multimedia contents broadcasting equipment 100a. The individual multimedia contents broadcasting equipment 100b having a relay function is formed in the same construction as the individual multimedia contents broadcasting equipment 100a which performs the above broadcasting functions, provided that there are differences only in the contents received from the individual multimedia contents broadcasting equipment 100a. So, the construction and operations of the same will be omitted. The above relay function is provided for overcoming the limits in the LAN radio communication radius. When the relay function is used, an expansion of the independent radio network for an individual broadcast might be possible. The relay function will be described later with reference to
The individual multimedia contents broadcasting equipment 100a according to the present invention might be configured in fixed broadcast equipment or portable broadcast equipment. In case of the fixed type, an individual information communication instrument such as a desk top system except for a portable or mobile communication instrument might be used. In case of the portable type, a portable individual information communication instrument such as a mobile communication terminal, a PDA, a palm top computer, a UMPC, a navigation device, a portable game unit or something might be used. The individual multimedia contents broadcasting equipment 100b having a relay function might be a mobile system while maintaining a radio communication radius which is a relatively shorter distance as compared to the fixed type.
As shown in
An individual broadcast driving instruction inputted through the operation unit 104a depending on a broadcaster's operation is interpreted by means of a key input module 202a, and is transmitted to the controller 103a. The controller 103a judges whether the multimedia contents stored in the storing device 103b are broadcasted or the multimedia contents inputted through the input and output unit 104 are broadcasted in real time in a step S400.
In case that the individual broadcast driving instruction corresponds to a recording broadcast in which the multimedia contents stored in the storing device 103b are broadcasted, the controller 103a transmits the multimedia contents stored in the storing device 103b to the radio communication instrument 102, and a corresponding broadcast beings in a step S402.
When the broadcaster selects a real time broadcast, the text data and symbol data inputted trough the operation unit 104a are interpreted by means of the key input module 202a, and the music data, audio data and sound data inputted through the microphone 104a are interpreted by means of the audio input module 202b, and the image data, image data, and photo data inputted through the camera 104c are interpreted by means of the video input module 202c. The above data are sequentially transferred to the controller 103a in a step S401. The controller 103a creates multimedia contents in real time in a sequence of the input, and stores into the storing device 103b, and transmits the multimedia contents created in real time through the radio communication unit 102, and the broadcast begins.
In the steps S402 and S403, the multimedia contents, which are individually broadcasted, are outputted to the speaker 104d by the process of the controller 103a, and the music data, audio data and sound data are outputted to the speaker 104d through the audio output module 202d. The video data, image data, and photo data are outputted to the LCD 104e through the video output module 202e. The broadcaster performs a broadcast while checking the contents of the multimedia contents which are being broadcasted through the output unit of the individual multimedia contents broadcasting equipment 100a.
In the step S401, when the multimedia contents stored in the storing device 103b with a periodically repeated judgment process after the individual broadcast has begun are broadcasted, the multimedia contents inputted through the input and output device 104 are combined with the multimedia contents of the storing device 103b depending on the process of the processor 103a as a result of the judgment of the step S401 and are broadcasted.
Next, the controller 103a judges a connection request of the receiving terminal 300. When there is a request, a private IP allocable to the receiving terminal 300 which requested a connection with reference to the current private IP information managed by means of the private IP management module 200b through the DHCP module 200a is selected and automatically allocated to the receiving terminal for thereby setting a connection in steps S404 and S405.
When an authentication function is not activated after a connection is set, the authentication module 200c receives authentication information from the connected receiving terminal 300 and compares with the authentication information stored in the storing device 103b for thereby judging whether the connected receiving terminal is the receiving terminal 300 registered in the connection terminal management module 200e in steps S406 and S407.
As a result of the judgment of the registration, when the connected receiving terminal is not the authenticated receiving terminal 300, the allocated private IP is retrieved, and the connection is automatically disconnected, and the broadcast receipt is prohibited in a step S408, and in case of the authenticated receiving terminal, the step S409 is performed.
Next, the controller 103a judges whether there is a playback tool in the authenticated receiving terminal 300 for playing back the broadcast contents with the helps of the playback module 200d in a step S409, and when a playback tool is not installed, the playback tool stored in the storing device 103b is transmitted to the receiving terminal 300 using the playback tool module 200d and is installed in a step S410. When an individual content can be played back in the receiving terminal 300, the controller 103a transmits a currently broadcasting content selected by the broadcaster to the receiving terminal 300, and the receiving terminal 300 receives the broadcast content and plays back the same. At this time, the connection terminal management module 200e of the individual multimedia contents broadcasting equipment 100 periodically transmits a connection state of the receiving terminal 300 to the video output module 202e, and the video output module 202e indicates the connection state of the receiving terminal 300 on the LCD 104e and periodically manages the same.
When the individual broadcast is continuously performed, the routine is repeated from the step S401 to the step S412. When it is judged that the individual broadcast is finished, the individual broadcast operation is stopped in a step S412.
