A reproduction device includes: an HDMI transmitter that detects a power state of a display device; a first communication module that establishes communication with a terminal device that is externally located, when the HDMI transmitter does not detect that the display device is in a power-on state; and a controller that performs first settings with the terminal device, when the communication is established between the terminal device and the first communication module, the first settings being settings relating to the reproduction device.

Reproduction device, reproduction device control method, and recording medium

A remote control system includes a main body apparatus and a remote controller. A motion sensor included in the remote controller detects an amount of change in posture of the remote controller. A user interface creator included in the main body apparatus creates a user interface image including a pointer. The user interface creator: determines virtual coordinates of the pointer based on the amount of change in posture; when the virtual coordinates of the pointer are present in a movable region, displays the pointer at a position of the virtual coordinates; when the virtual coordinates of the pointer are present outside the movable region, displays the pointer at a position in the movable region closest to the virtual coordinates; and when the virtual coordinates of the pointer have reached a boundary of a clip region, limits the virtual coordinates of the pointer within the clip region.

Remote control system and electronic device

A recording device includes a recording medium operable to store a plurality of program streams and information about recording of each program stream, and a controller operable to control display of the program stream recorded on the recording medium on a display device. When receiving an instruction for selecting a predetermined item from among the plurality of selection items, the controller causes the menu image to be displayed, making the menu image include information representing programs corresponding to at least a part of the plurality of the program streams recorded on the recording medium, in addition to the plurality of selection items.

An apparatus and method for addressing data losses when power to a digital recorder is unexpectedly interrupted during recording, and a the file management information needed to play back digital content is not completely written to a disc. The recovery process for correcting inconsistencies between the AV data and management information left on the disc is time-consuming. By recording the recovery data used for the data recovery process when power is turned on again, the management information can be recompiled based on the recovery data. Thus, inconsistencies between the AV data and management information can be corrected. Additionally, AV data and recovery data in this case can be written alternately to contiguous areas on the disc.

A content-transmitting apparatus transmits reproduction control information including order of reproduction, reproducing section, and reproduction date information of contents which transmitted in the past. In a content-receiving apparatus, when a transmission destination chooses a specific television channel using a receiving side input unit, a receiving side control unit reproduces contents according to the reproduction control information. When the transmission source controls contents including the contents which transmitted in the past to the transmission destination, the transmission destination can view and listen to the contents that the transmission source intends to reproduce, with easiness just like changing television channels.

A video frame is input to a spectrum analyzer, which transforms the frame from a spatial domain into a frequency domain. A resolution determiner analyzes the output of the spectrum analyzer, thereby selecting a resolution appropriate for the video frame. Then, a resolution converter converts a resolution of the video frame into the resolution selected by the resolution determiner. Thereafter, the video frame is subjected to a coding process by block divider, DCT transformer, quantizer and variable-length coder so as to be output as a coded bit stream. By coding the input video frame at a resolution corresponding to the high-frequency component in the frame, a video of higher quality can be obtained with the bit rate reduced.

Image coding apparatus

An encoding/recording device encodes a video signal according to MPEG, encodes an audio signal with a predetermined method, and multiplexes the encoded video signal and the audio signal to produce a system stream. The encoding/recording device then records the system stream onto a recording medium. On receiving a pause instruction, the encoding/recording device suspends reception of the audio signal and the video signal in synchronization with a timing with which the video signal is received, and thereafter suspends encoding, multiplexing, and recording for the audio signal and the video signal with predetermined timings. On receiving a pause release instruction, the encoding/recording device resumes reception of the audio signal and the video signal in synchronization with a timing with which the video signal is received, and thereafter resumes the encoding, the multiplexing, and the recording with predetermined timings. When suspending the encoding for the video signal, the encoding/recording device keeps information showing how an amount of video data accumulated in a buffer in a virtual decoder changes, and uses the kept information when resuming the encoding.

A digital recording apparatus that obtains a digital stream including a plurality of frames, while recording the digital stream on a digital recording medium. This apparatus obtains, during recording, an instruction for a procedure in which a recording area is changed to another recording area which is not necessarily continuos with the recording area. When the instruction is obtained, the apparatus executes the procedure only when the number of frames which are recorded in the recording area is a predetermined number or more.

Digital recording apparatus that secures a certain number of video frames in a VOB constituting with another VOB a portion of encode stream that should be reproduced seamlessly

A digital video recording apparatus reduces the audio output level before and during changes in an audio encoding condition (stereo, monaural, etc.). One embodiment of the digital video recording apparatus multiplexes video and audio signals to produce an output stream. A video recording control means controls the apparatus according to user input and design.
