20080240685 | Recording and reproducing apparatus - A recording and reproducing apparatus capable of recording and reproducing the signals of both a digital broadcast system and an analog broadcast system is disclosed. By utilizing the existing configuration efficiently, the cost increase due to the system change is minimized. Both the digital broadcast system and the analog broadcast system are connected to a connector to receive both digital and analog broadcast signals. The analog broadcast signal input through the connector is recorded in a digital broadcast signal recording unit of the digital broadcast system under the control of the control unit included in the digital broadcast system. | 10-02-2008 |
20080317436 | DIGITAL SIGNAL RECORDER WITH SELECTIVE ENCRYPTION AND KEY GENERATION - A digital signal recorder for recording a digital signal on a recording medium, including: an input circuit which receives a transmitted digital signal encrypted for protecting said transmitted digital signal using a first encryption method; a decrypting circuit which decrypts said transmitted digital signal into an original data; a key generation circuit which performs a prescribed arithmetic operation to generate a key; an encrypting circuit which receives said key and said original data, and encrypts said original data with said key using a second encryption method; a recording circuit which records, onto said recording medium, a key information which is used for decrypting said encrypted digital signal together with said encrypted digital signal, and a timing control circuit which controls decrypting timing of said decrypting circuit and encryption timing of said encrypting circuit; wherein said key generation circuit has a function for updating said key in connection with recording units of said recording media. | 12-25-2008 |
20100073455 | Television receiver with a TV phone function - A videophone system includes a processor which selectively sets a television (TV) broadcast program viewing function mode and videophone function mode in response to manual operation of a remote control, a decoder which performs, in the TV program view mode, a TV program-use decode function for decoding a broadcast program signal received from a TV tuner to thereby display it on a display screen while producing audio sounds by loudspeakers and which performs, in the videophone function mode a videophone-use decode function for decoding a videophone signal received from a distant party to thereby display on the screen an image of the distant party using the screen and speakers, and an encoder which performs a videophone-use encode function for encoding a video signal from a camera and a voice signal from a microphone to generate a videophone signal, which is sent to the distant party via a network. | 03-25-2010 |
20100106960 | CONTENT TRANSMITTING DEVICE, CONTENT RECEIVING DEVICE AND CONTENT TRANSMITTING METHOD - Before content transmission, the content transmitting device and the content receiving device mutually authenticate each other to verify that the other device respects copyright and rightfully handles content, and then content is encrypted by shared key data and transmitted. It is arranged that in an authentication process, a time from transmission of an authentication request or a time from transmission of an authentication response until arrival of receipt acknowledgement data is measured and only when a measured time is less than a fixed upper-limit value, content is transmitted. | 04-29-2010 |
20100254242 | Digital Information Recording and Reproducing Method and Apparatus Therefor - A method is disclosed wherein a first piece of digital information and copy control information of the first piece of digital information is received. The copy control information is for controlling the recording of the first piece of digital information on a recording medium. When the received copy control information is Copy One Generation indicating that only one generation copy of digital information is allowed, then a plurality of the first pieces of digital information are recorded on a first recording medium as the first piece of digital information and a second piece of digital information, wherein the first piece of digital information is different in format or in bit rate from the second piece of digital information. | 10-07-2010 |
20120113218 | RECEIVING APPARATUS AND RECEIVING METHOD - It is an object of the present invention to provide a content receiving apparatus capable of receiving, storing, and externally exporting content distributed from various networks. A receiving apparatus for receiving a digital signal in which a 3D video program and a 2D video program are mixedly present, includes a program selection unit configured to display and select a received program list; and a function determination unit configured to determine a function of viewing the 3D video program and 2D video program included in the receiving apparatus, wherein the program selection unit displays a viewable program list of the receiving apparatus according to a determination result of the function determination unit at the time of displaying the received program list. | 05-10-2012 |
20120120204 | RECEIVER - A receiver to receive 2D and 3D content from a content distributor, including a content list obtaining unit obtaining a list screen of content receivable from the content distributor, a content obtaining unit obtaining 2D or 3D content from the content distributor, a display unit displaying the list screen and reproduced screen of the content on an external or built-in monitor, and a function determining unit determining a function for viewing/listening to 3D and 2D content, wherein the content list obtaining unit determines if 3D content is visible/listenable and obtains a content list of only 2D content or both 2D and 3D content, in accordance with a result of determination, from the content distributor, and the display unit displays the content list obtained through the content list obtaining unit, thereby enabling the receiver of content to receive, memorize and/or output outside the content, being distributed from various networks. | 05-17-2012 |
20130127977 | TELEVISION RECEIVER WITH A TV PHONE FUNCTION - A videophone system includes a processor which selectively sets a television (TV) broadcast program viewing function mode and videophone function mode in response to manual operation of a remote control, a decoder which performs, in the TV program view mode, a TV program-use decode function for decoding a broadcast program signal received from a TV tuner to thereby display it on a display screen while producing audio sounds by loudspeakers and which performs, in the videophone function mode a videophone-use decode function for decoding a videophone signal received from a distant party to thereby display on the screen an image of the distant party using the screen and speakers, and an encoder which performs a videophone-use encode function for encoding a video signal from a camera and a voice signal from a microphone to generate a videophone signal, which is sent to the distant party via a network. | 05-23-2013 |
20130287122 | VIDEO TRANSMISSION DEVICE, VIDEO TRANSMISSION METHOD, VIDEO RECEIVING DEVICE, AND VIDEO RECEIVING METHOD - A video transmission device comprising: a reference signal generation unit which generates a reference signal based on time information; an imaging unit which images a video signal based on the reference signal generated by means of the reference signal generation unit; a compression unit which performs digital compression encoding of the video signal imaged by means of the imaging unit; a network processing unit which receives, from a network, time information and phase information about a reference signal in regard to the time information and, also, transmits the digital compression encoded video signal; and a control unit which controls the reference signal generation unit and the network processing unit.
