  • Patent number: 8644687
    Abstract: In a recording apparatus (camcorders, optical disc recorders, etc.), the operator presses down priority designating buttons for designating priorities when recording input image data. An additional information generating section records and holds, in a storage section, additional information indicating priorities of data to be recorded (e.g., “low”, “intermediate”, “high”, or “highest”) which are set, depending on what priority designating button has been pressed down. If recordable remaining space in the storage section detected by the remaining amount detecting section falls below a predetermined value before the start of or during recording of data, a control section overwrites regions in order of priority of data which is stored therein, the lowest first, with data which is about to be recorded or is being recorded, based on the additional information generated by the additional information generating section.

  • Publication number: 20110228685
    Abstract: A buffer has a predetermined storage capacity, and accumulates data received from an external device. A transmitting unit reads data from the buffer and transmits the data to a mobile terminal. A transmission rate determining unit determines the transmission rate for transmitting data from the external device to its own device, based on the free space in the buffer. The window size notifying unit notifies the mobile terminal of a window size in accordance with the determined transmission rate.

  • Publication number: 20090274095
    Abstract: A mobile wireless communication system includes: a wireless base station that controls, for each timing, a transmission state of a radio wave repeatedly transmitted at timings that respectively differ; and a plurality of wireless mobile devices that are respectively allocated one of the timings, receive the radio wave at the timing allocated, and based on the radio wave received, respectively detect a connection destination. The wireless base station controls the transmission state of the radio wave transmitted at an arbitrary timing to be any one of a complete suspension state of continuously suspending transmission, a discontinuous suspension state of discontinuously suspending transmission, and an invalid information transmission state of transmitting invalid information.

  • Patent number: 6647202
    Abstract: A video signal reproduction apparatus is provided for reproducing a multiplexed encoded stream including audio data, video data, sub-picture data, and additional information digitally encoded and multiplexed on a packet-by-packet basis. The multiplexed encoded stream includes a plurality of packs, each of the plurality of packs including at least one packet, the at least one packet including a packet header and packet encoded data. The packet encoded data includes at least one of packet audio encoded data, packet video encoded data, packet sub-picture encoded data, and packet navigation encoded data. The packet audio encoded data forms sub-picture encoded data, the sub-picture encoded data including a first reproduction unit and a second reproduction unit. The first reproduction unit includes a first unit header, first encoded bit map data, and first display control information, and the second reproduction unit includes a second unit header, second encoded bit map data, and second display control information.

  • Patent number: 6335764
    Abstract: A video output apparatus comprises: video data processor for processing plural pieces of video data of different types and outputting the resulting video data to a monitor; video processing delay detector for detecting whether processing for the plural pieces of video data performed by the video data processor is completed in real time when it is output to the monitor; and video data processing controller for controlling the video data processor so that the processing performed by the video data processor which is allocated for on line period is reduced when the video processing delay detector detects delay in processing.

  • Patent number: 4539553
    Abstract: A digital-to-analog converter of the current-adding kind includes n input buffer circuits to which the bits of the digital signal are applied in parallel, a first ladder resistor network having n resistors connected in series to which complementary outputs of the input buffer circuit are connected, a second ladder resistor network for dividing output terminal voltages from the first ladder resistor network into 2(2.sup.n -1) voltages, (2.sup.n -1) switching circuits having inputs connected to voltage dividing points of the second resistor network, and a common summing resistor connected to the outputs of the switching circuits to add currents supplied thereto, thereby providing an analog voltage having a level corresponding to the numerical value of the digital input signal.

  • Patent number: 4395021
    Abstract: A vertical continuous annealing furnace has two furnace covers vertically spaced away from each other. Each furnace cover is laterally slidable with respect to the furnace proper and has two long narrow openings through which strip is passed. There is a relatively small pre-chamber between the first furnace cover above and the second furnace cover below. The space below the second furnace cover constitutes a heating chamber. A partition extends from the undersurface of the second furnace cover to near the bottom of the furnace, dividing the heating chamber into a heating zone and a soaking zone. In charging and discharging the strip, the two furnace covers are alternately opened and closed, thereby keeping the heating chamber out of exposure to the outside air.
