Abstract: This control device is connected to a master device and controls a drive target on the basis of the content of communication with the master device, and includes a communication unit which periodically transmits to and receives from the master device first information, which is information relating to control of the drive target, and second information, which is information relating to safety; a first processing unit which controls the drive target by processing the first information; a second processing unit which, by processing the second information, performs processing to ensure safety of the drive target; and an abnormality determining unit which determines that an abnormality has occurred if both the first information and the second information have not been processed within a prescribed period.

Abstract: A temperature monitoring device of the present invention includes: a current value acquisition portion (50) that acquires a current value supplied for the motor; a calorific value inference portion (20) that infers a calorific value through a first thermal model indicating a relationship between the current value and a calorific value of a servo driver (2); and an anomaly judgment portion (10) that compares the calorific value with a threshold, so as to judge whether there is heating anomaly.

Abstract: A stream input unit (102) receives a transport stream. A subtitle information extracting unit (104) separates the received transport stream into subtitle information and information other than the subtitle information. Next, a stream format converting unit (105) converts separated video/audio information contained in the transport stream into a program stream of video/audio. A subtitle format converting unit (107) converts the subtitle information separated by the subtitle information extracting unit (104) into a program stream of subtitle information. Thereafter, a subtitle information inserting unit (108) inserts the subtitle information converted by the subtitle format converting unit (107) into the program stream converted by the stream format converting unit (105), and outputs the resultant program stream.

Abstract: A program recording apparatus for recording a program transmitted in a transport stream, includes an information acquisition portion which acquires genre information about the program from each TS packet of transmitted transport stream data, a conversion portion which converts the transport stream data into data in a predetermined format, a recording portion which records the transport stream data or the data in the predetermined format on a record medium, a control portion which controls at least one of the information acquisition portion, the conversion portion and the recording portion, and a storage portion which stores profile data in which a recording format every genre is set. The control portion controls at least one of the information acquisition portion, the conversion portion and the recording portion based on the profile data when the genre information about the program acquired by the information acquisition portion is set in the profile data.

Abstract: A stream data recording apparatus includes a data object generation section for receiving video/audio data and generating from the video/audio data a data object complying with a standard with respect to the recording, a buffer for temporarily accumulating the generated data object by the data object generation section, and an optical recording section for writing the accumulated data object in the buffer to the optical recording medium. In this apparatus, the optical recording section performs initial preparation for data writing to the optical recording medium during generation of the data object by the data object generation section.

Abstract: A transmission apparatus which alleviates, compared to conventional apparatuses, a processing burden such as transmission position management for terminals, which is required for video data distribution in a video-on-demand system distributing video data according to requests from user-side terminals. A transmission apparatus 100 uses an accumulation buffer control subunit 105 and a user buffer control subunit 106 to manage an accumulation buffer 102 of the transmission apparatus and a user buffer 153 of a playback apparatus. Upon receipt of a video data transmission request from the playback apparatus 150, the transmission apparatus 100 determines an accumulation buffer to be assigned to the playback apparatus.
