Abstract: The present disclosure relates to an information processing apparatus, an information processing method, and a vegetation management system each capable of managing vegetation in such a manner as to maintain a high quality state and achieve uniform growth. In a vegetation management system, an image acquiring apparatus acquires an image in which vegetation corresponding to a target of management is captured. An analysis unit analyzes the image as at least input information and outputs a predetermined analysis result. Then, a determination unit determines work contents to be performed for the vegetation, according to the analysis result. A work apparatus performs a process for executing work for the vegetation according to the work contents. For example, the present technology is applicable to a management system that manages natural grass.

Abstract: A system in which content usage conditions can be upgraded without the need for a service provider to control content-usage rights of a user. In the system in which encrypted content is distributed and is allowed to be utilized only by authorized users, the service provider receives a content usage-right certificate from the user, and on the condition that it is determined that data is not tampered with by verifying a digital signature of an issuing entity of the content usage-right certificate, the service provider obtains user information and content purchase information of the user from the content usage-right certificate, and performs upgrade processing by, for example, changing the usage conditions. It is thus possible to change the content usage conditions without the need for the service provider to possess usage control data.

Abstract: An information source management system 11 performs inventory management for CDs and a material information management progress programming system 12 performs programming. An material information registration system 13 compresses the musical numbers of the CDs for holding on a proprietary server and a proprietary server 121 of a multi-channel sending-out system 101. A large number of materials are held on the proprietary server 121 and read out from it. The read-out materials are converted in its format to a transmission format by a sending-out server 123 so as to be multiplexed by a multiplexer 141. The multiplexed data is QPSK-modulated by a modulator 142 and sent out via a selector 143. From the proprietary server 121 are read out data which is sent out via dedicated network 3 to a live PC where it is reproduced. This data is furnished again via dedicated network 3 and encoded by an MPEG encoder 129 so as to be sent out at the sending-out server 123.

Abstract: An image processing apparatus separates input image data into low resolution image data and one or more auxiliary image data for interpolating the low resolution image data, and decrypts at least one of the separated auxiliary image data. The image processing apparatus also separates input image data into low resolution image data and at least one auxiliary image data for interpolating the low resolution image data and decodes the image data with at least one of the auxiliary image data being encrypted, and decrypts the encrypted auxiliary image data and synthesizes the low resolution image data with the auxiliary image data.

Abstract: In a scrambler used in the transmission side, a decryptor for generating a work key from a data key and system keys uses the same decryption algorithm as that used in a decryptor for encryption in the OFB mode. Under this condition, in a descrambler used in the receiving side, a decryptor for generating a work key from a data key and system keys can use the same decryption algorithm as that used in a decryptor for encryption in the OFB mode. In addition, another decryptor can use the same decryption algorithm. Therefore, one decryptor can serve as these three decryptors. The scale of the descrambler configuration can be reduced.

Abstract: A video signal recording apparatus is capable of compressing the amount of information of a video signal sequentially containing a plurality of pictures correlated to one another. In this compression, the video signal recording apparatus can selectively assume an intrapicture coding mode for executing compression by using only a correlation within each of pictures of the video signal and an interpicture coding mode for executing compression by using a correlation between a plurality of pictures of the video signal. When a video signal the amount of information of which is compressed is to be recorded on a recording medium, the video signal recording apparatus starts recording with a video signal compressed in the intrapicture coding mode.

Abstract: An electronic content providing method relates to a system in which music is downloaded by using an information terminal installed in a store, and enables a user to rapidly specify and purchase a desired electronic content by using the information terminal in the store. Specifically, in the method, the user accesses a server containing information on electronic contents by using a user terminal such as a mobile phone, retrieves a desired electronic content from among the electronic contents, and acquires an identification code for identifying the retrieved electronic content. By inputting the identification code acquired by using the user terminal to the information terminal, the desired electronic content is specified without performing an electronic content retrieving process. As a result, the user can rapidly perform a process of purchasing the desired electronic content.

Abstract: An image coder includes an input unit for inputting an image signal, a coding unit for coding the image signal by adaptively switching a first coding mode for performing intraframe coding and a second coding mode for performing interframe coding, and a command unit for outputting a command to the coding unit to forcibly execute the first coding mode. The command unit outputs a command at intervals controlled in accordance with the quantity of coded data generated when the image signal is coded. Alternatively, the image coder includes an input unit for inputting an image signal, a detection unit for detecting the activity of the image signal input by the input unit, a coding unit for coding the image signal by adaptively switching a first coding mode for performing intraframe coding and a second coding mode for performing interframe coding, and a command unit for outputting a command to the coding unit to forcibly execute the first coding mode.

Abstract: An image display apparatus for displaying an image corresponding to an image signal selectively inputs a first image signal and a second image signal having an aspect ratio different from that of the first image signal. When the second image signal is input, the second image signal is converted into an image signal corresponding to the aspect ratio of the first image signal, and the converted image signal is supplied to an image display unit for displaying an image corresponding to the aspect ratio of the first image signal. Thus, it is possible to display an image in a manner easy to observe, and to effectively utilize the display picture surface.
