KR20060033340A - Home logging system for recording and retrieval for audio and video data in digital home - Google Patents

Abstract

This invention is a digital home controlled by a home server where many devices in the home are connected through a communication medium and can send and receive information. Records video and audio signals of door phones used for identification of the user in real time under the control of the home server and stores them locally in the recording system (hereafter home logging system) or outside the home. It is a system that can search and manage the contents stored in the storage and access through the home server or the Internet, TV, PC or telephone.

The present invention relates to a digital home in which all devices in the home are controlled by a home server. The home server is controlled by a home server to record voice and video information generated by CCTV or door phones and calls made through the phone. It is recorded in the form of, and stored in the internal storage of the home logging system or the storage located outside of the home, so that the stored information can be retrieved regardless of the storage location inside or outside the home, to increase user convenience. Provide the function.

The present invention is a digital home controlled by a home server under the control of the home server, the number of call times, call numbers, caller numbers, call history, etc. that occur during wired communication, security CCTV and door phone, etc. Signal to the home logging system located in the home to be integrated and stored using the storage device in the home or the external storage device, and then conveniently using the search server connected to the home server or home server or the Internet. Make it searchable.

The present invention is a system for recording, storing, and retrieving voice and image data related to security and data related to wired communication in a digital home controlled by a home server, the connection diagram of which is shown in FIG. The home server of FIG. 1 is a system for controlling all aspects of the digital home, and generates information for controlling the operation of the home logging system. The home logging system has a separate home server interface to receive various information requested by the home server, and thus can communicate with the home server smoothly.

The home logging system of FIG. 1 has an interface for recording in FIG. After receiving and digitizing the signals of CCTV and door phone used for crime prevention, they are stored in the temporary folder of the local by the control signal of the home server. In the case of the door phone, it is configured to record using the method of starting and ending the recording by the control signal of the home server and the method of automatically starting and ending the recording when the signal exists by analyzing the signal of the door phone. . This process is shown in FIG. In FIG. 4, recording of data is started by a signal arrived at a door detection signal of a door phone or a command that arrives first from a recording start command from a home server, and ending is also terminated by a command that arrives earlier. Also, recording of data can be continued.

The recording of CCTV signal is started by the start command of the home server, and it uses the method of recording only for a predetermined time by one start command. If you want to continue recording, you should apply the periodic start signal. . The matters related to the recording of CCTV are shown in FIG. 5.

For calls on landline phones, the phone number pressed for outgoing calls and the caller ID for incoming calls are stored as information other than voice.The record is used to detect the start signal of the home server or the hook signal of the phone in the same way as the door phone. The recording starts with the start condition that arrives first, and the recording ends with the end condition that arrives first.

All records described above operate according to the rules set by the home server and are configured to prevent unauthorized writing.

Through the above process, the data recorded in each device varies the storage method depending on the importance of the data. The signals such as CCTV related to the security are stored in the local storage and encrypted and transmitted to the remote storage.In the case of door phone or telephone call, the recording is completed locally after the recording is completed. Is sent to the repository. Locally stored data in the home logging system is stored for a period specified by the home server's settings.If the storage period has elapsed, the data is automatically deleted.If the deleted data is requested, the data stored in the remote storage is stored. It is configured to import and complete the search.

3 shows an interface that a home logging system has in order to retrieve locally stored data. Home logging systems can accommodate searches by home servers, searches by the Internet, and searches by phone, all of which are configured to support independent searches. The home network (home server) interface unit of the search interface of FIG. 3 may exchange data with a physical result such as signal conversion or protocol conversion for exchanging data with the home server and the search result by a promised search result notification protocol. It is an interface composed of H / W and S / W that are prepared to be. The second part of the retrieval interface, the IP network interface, contains the functionality of a network card and consists of a TCP / UDP protocol stack for IP data exchange and a web program that processes the retrieved results. The third part of the search interface, the wired telephone network interface, is a circuit for sending and receiving audio signals to the telephone network, a part for checking hook status, a part for checking telephone line connection, and a hook on / off function and a ring. It consists of the function of receiving count function, DTMF and CID, and in case of accessing through telephone for searching, after the ring count set by the home server, the telephone network interface receives the call by itself and goes through the user confirmation procedure. Search is performed, and the search is achieved by separating and reproducing the voice signal only for the recording of the door phone or telephone call in which the voice signal exists.

During the data retrieval, data whose actual data portion is deleted after the retention period set by the home server has elapsed is accessed to complete the retrieval after receiving the data by accessing the remote storage.

The present invention can increase the security effect of the home by collecting and storing audio and video signals generated by a security CCTV or door phone under the control of the home server in the digital home controlled by the home server. In addition, all the information of the call, such as voice signals generated from wired calls and call start time, call time, caller information (CID), receiver information (phone number of the called party), etc. You can implement the recording function for the call history by saving.

The collected data is stored either locally or remotely in the home logging system.If the data stored locally is deleted after the retention period has elapsed, the information stored remotely can be retrieved to store data related to the digital home. It is effective to create ASP service.

Claims (5)

In the digital home controlled by the home server for the convenience of the residents, the interface function for collecting the communication and security information generated inside and outside the home, the storage function for storing the collected data, and the search for the stored data A home logging system comprising an interface function for communication and an interface function for communication with a home server.
