Abstract: A character input apparatus includes a display an input module and an area controller. The display displays characters and a cursor position. The input module has a plurality of keys for instructing deletion of characters displayed on the display. The area controller (i) measures a press time in a case where a key of the input module is pressed, (ii) determines whether the press time is a short time or a long time, (iii) performs an input unique to the key when the press time is a short time, and (vi) instructs a transition to a long press mode to delete characters in a range predetermined with respect to the cursor position when the press time is a long time.

Abstract: One embodiment provides a wearable electronic apparatus including a non-contact sensor, a judgment section and a controller. The judgment section judges whether the electronic apparatus is in a worn/carried state or in a non-worn/carried state on the basis of a detection value of the non-contact sensor. The controller which sets an operation mode of the electronic apparatus into a first mode or a second mode based on a judgment result of the judgment section. If the judgment section judges that the electronic apparatus is in the worn/carried state, the operation mode is set into the first mode. If the judgment section judges that the electronic apparatus is in the non-worn/carried state, the operation mode is set into the second mode.

Abstract: One embodiment provides a host controller which performs a phase shift correction of a sampling clock when sampling a signal received, includes a phase shift judging section which judges whether or not it is necessary to shift a phase of the sampling clock, and up/down counts a counter in accordance with a shift direction when judging that it is necessary to shift the phase, a limit value storage section which stores a variance range limit value of the phase shift, and a shift limit judging section which judges whether or not a value of the counter exceeds the limit value of the phase shift, notifies a host device of an error when judging that the counter value exceeds the limit value, and shifts the phase of the sampling clock in accordance with the counter value of the counter when judging that the counter value does not exceed the limit value.

Abstract: According to one embodiment, there is provided a host controller. The host controller includes a plurality of data input sections and a controller. The plurality of data input sections is configured to repeat an operation of acquiring a plurality of values by sampling a content of read data and additional information accompanying the content with a plurality of clocks of different phases. The controller is configured to adjust phases of the clocks based on the plurality of values acquired by the data input sections.

Abstract: According to one embodiment, a playback apparatus plays back digital content data stored in storage media. The digital content data includes main video data and sub-picture data including a plurality of kinds of subtitles. A detection module detects display positions and display sizes of two or more kinds of subtitles which are selected from the plurality of kinds of subtitles. A video process module calculate a reduction ratio, which is to be applied to the main video data, on the basis of the determined display positions and display sizes of the two or more kinds of subtitles, and reduces the main video data with the calculated reduction ratio, thereby to prevent the subtitles from overlapping a display area of the main video data. An output module composites the reduced main video data and the determined subtitles, and outputs video data which is obtained by the compositing.

Abstract: Encrypted content, an encrypted content key and an encryption key are generated. The encrypted content and the encrypted content key are delivered to a local server via a network and are stored. A decryption key for decrypting the encrypted content key that corresponds to a reproduction request for predetermined content, and the encryption key for re-encrypting the decrypted content key that is decrypted by the decryption key are delivered via the network. Thereby, the encrypted content is decrypted using the decrypted content key. The decrypted content key is re-encrypted using the encryption key, and the stored encrypted content key is updated with the re-encrypted content key, and the updated content key is stored.
