20100046931 | RECORDING AND PLAYBACK APPARATUS - A recording and playback apparatus including a recording unit configured to download additional information of a content stored in the server to perform a preparing operation for starting download of the content, and to download the content from the server upon completion of the preparing operation to record the downloaded content in the recording medium, and a display data creating unit configured to create data of a list image for displaying information of each content in all or part of contents stored in the recording medium. The display data creating unit creates the data of list image so that a list image displayed when the recording unit is downloading additional information is different from a list image displayed when the recording unit is downloading the content. | 02-25-2010 |
20100186092 | NETWORK AUDIO-VIDEO CONTENTS PLAYBACK TERMINAL, SERVER, AND SYSTEM - Methods to set a viewing and/or listening term are classified into two types, which are a fixed-time-length type to limit time length and a fixed-expiration-time type to limit expiration time. And the timings of license acquisition are classified into two types which are an immediate-acquisition type and a point-of-use type. The type of the timing of license acquisition is written to a meta data which is to be sent to a terminal before initiating download. The terminal determines the timing of license acquisition according to the meta data. When contents are point-of-use type, the terminal doesn't acquire a key and an expiration time information until a time of initiating playback. On the other hand, when contents are immediate-acquisition type, the terminal acquires the key and the expiration time information at any point of time. Since the key is acquired at the early timing such as download completion timing, a reaction velocity in response to a playback instruction can be heighten. | 07-22-2010 |
20100268621 | NETWORK AV CONTENTS PLAYBACK TERMINAL, SERVER, AND SYSTEM - In a service of downloading contents whose contract is to be automatically renewed, an establishing of a synchronization between information about a period stored on the side of a terminal and information about a period to be renewed on the side of a server, causes a problem of load increase and others because a large amount of contents have to be synchronized at frequent intervals. | 10-21-2010 |
20100322591 | RECORDING/REPRODUCING DEVICE - A recording and playback apparatus includes a download recording unit configured to download a content stored in the server and record the content to the recording medium as a download content, a broadcast recording unit configured to record the broadcast program received via a broadcast wave to the recording medium as a broadcast content, and an erasing unit configured to erase the download content or the broadcast content recorded in the recording medium. The erasing unit determines whether the content can be erased or not based on attribute related to erasure of the content. The download recording unit sets the attribute related to erasure to a value indicating prohibition of erasure, when recording the download content to the recording medium. The broadcast recording unit sets the attribute related to erasure to a value indicating allowance of erasure, when recording the broadcast content to the recording medium. | 12-23-2010 |
20110002593 | RECORD-PLAYBACK DEVICE - A recording and playback apparatus capable of recording a content downloaded from a server to a recording medium, and playing back the content, includes a recording unit configured to download the content with a playback time limit from the server and record the content to the recording medium, a playback unit configured to play back the content recorded in the recording medium, and a display data generating unit configured to generate data of a list image for displaying a list of information of each of part or all of contents recorded in the recording medium. The data of a list image is generated so that, before the playback unit plays back a content with a playback time limit, the list image includes information indicating an allowed playback period of the content, and, after the playback unit plays back the content, the list image includes information indicating the playback time limit of the content. | 01-06-2011 |
20110002662 | RECORDING/REPRODUCING DEVICE - A recording and playback apparatus capable of recording and playing back a content downloaded from a server, includes a recording unit configured to download the content with a playback time limit, stored in a server and record the content to a recording medium, an instruction receiver configured to receive an instruction for starting playback of the content, a playback unit configured to play back the content recorded in the recording medium in accordance with the instruction received by the instruction receiver, and a warning output unit configured to output warning information related to the playback time limit of the content before the playback unit stars playback of the content, when the instruction receiver receives the instruction for starting playback of the content during download of the content. | 01-06-2011 |
20120275758 | RECEIVING TERMINAL, AND CONTENT EXPORTING METHOD - A receiving terminal comprises a data acquiring unit which acquires from the content server information that is required for the export of the content and that includes information about a capability required for the receiving terminal and information about a capability required for the removable medium, a propriety judgment unit which compares the information about the capability required for the receiving terminal with information about a capability the receiving terminal possesses, compares the information about the capability required for the removable medium with information about a capability the removable medium possesses, and judges whether the export processing of the content can be performed or not, and a control unit which makes a processing relevant to a purchase of the content or to the export of the content perform, according to a judgment result by the propriety judgment unit. | 11-01-2012 |
20130326597 | AUTHENTICATION SYSTEM, INFORMATION REGISTRATION SYSTEM, SERVER, PROGRAM, AND AUTHENTICATION METHOD - The authentication system includes a plurality of user terminals that are used by the same user, and a server capable of communicating with the plurality of user terminals. A user terminal transmits, to the server, an identification ID of the user terminal, a first code that is used in common in the plurality of user terminals, and a second code that was encrypted using the first code. The server is configured to decrypt the encrypted second code using the first code, and perform authentication of the user terminal using the identification ID and the decrypted second code. The server, upon receiving a second code that is not encrypted from one of the plurality of user terminals, transmits the second code that was encrypted using the first code to the one of the user terminals. | 12-05-2013 |
20140020012 | SERVER COLLABORATION SYSTEM - The television device is capable of accessing a first server and a second server. The television device is able to execute a first program that is suitable for a process that requires responsiveness, and a second program that is suitable for a process that requires confidentiality. In the case of performing a sequential plurality of processes, when, of the sequential plurality of processes, a first process is performed that includes the process that requires responsiveness but does not include the process that requires confidentiality, the television device executes the first program to perform the first process by means of communication with the first server, and when, of the sequential plurality of processes, a second process is performed that includes the process that requires confidentiality, the television device executes the second program to perform the second process by means of communication with the second server. | 01-16-2014 |
