Abstract: To provide an information output apparatus in which even when the output of an isochronous packet containing the audio information or the like is suspended and restarted, the process for the audio information or the like can be quickly resumed and the occurrence of the headless state of the audio information after resumption of the process can be prevented.

Abstract: An information transmitting apparatus (such as player) is provided for transmitting information (audio data, video data, or others) to a plurality of information receiving apparatuses (such as receivers) via a serial bus. The transmitting apparatus has a selection unit to select one or more ones from the plurality of information receiving apparatuses and a transmission path establishing unit to establish a transmission path to the selected information receiving apparatus so that the information is transmitted therethrough. The operations required for transmission of the information can be simplified.

Abstract: An information transmitting apparatus (such as player) is provided for transmitting information (audio data, video data, or others) to a plurality of information receiving apparatuses (such as receivers) via a serial bus. The transmitting apparatus has a determination unit and a control unit. The determination unit is configured to determine whether or not one or more of the plurality of information receiving apparatuses are ready for receiving the information. The control unit is configured to make the information refrain from being transmitted by performing a waiting operation until the one of more information receiving apparatuses become ready for receiving the information in cases where the determination unit determines that the one or more information receiving apparatuses are not ready for receiving the information. The waiting operation allows the information transmitting apparatus to send to the information receiving apparatuses the information without dropping out a head portion of the information.

Abstract: An apparatus for reproducing information units recorded on a recording medium in a hierarchical structure having a plurality of levels. In the hierarchical structure, the information units are divided into a plurality of groups, and the groups are respectively assigned to the levels. The apparatus includes: an input device that receives an input instruction to designate one of the information units; a number determination device that determines the number of the information units included in each group; a level determination device that determines, on the basis of a determination of the number determination device, one of the levels to be searched in order to identify the designated information unit; and a reproduction device that identifies the designated information unit by searching the level determined by the level designation device, and reproduces the identified information unit.

Abstract: The present invention relates to a plasma etching method and a plasma etching apparatus, and more particularly to a plasma etching method and a plasma etching apparatus in which the selection ration is enhanced by improving trench side-wall protecting effect.
