  • Publication number: 20180376157
    Abstract: An image processing apparatus receives input of an original image that is divided into at least two partial images in a top-and-bottom direction. The image processing apparatus adds a first line number of dummy screen lines to a top portion of a partial image that is a top portion of the original image. The image processing apparatus adds a second line number of dummy screen lines to a lower portion of a partial image that is a lower portion of the original image. The image processing apparatus uses a z×z encoding process unit and performs an encoding process for each of the partial images to which the dummy screen lines have been added.

  • Patent number: 7869467
    Abstract: A clocking circuit of a receiving unit performs a clocking operation synchronously with a network clock. A packet output circuit of the receiving unit outputs a second packet included in a first packet and outputs a control signal indicating normality/abnormality of output timing of the second packet based on a result of comparing a time of the clocking circuit and a time of first time information included in the first packet. A clock adjusting circuit of a processing unit synchronizes, when the second packet includes second time information indicating a time based on a transmitting side reference clock and when the control signal indicates normality, a receiving side reference clock with the transmitting side reference clock based on a result of comparing a time based on the receiving side reference clock and a time of the second time information.

  • Patent number: 7652503
    Abstract: A semiconductor device includes an external pin, a control parameter decision circuit, and a register update circuit. The control parameter decision circuit includes a register and an output selector. The register is initialized in accordance with resetting of the semiconductor device. The output selector, according to a level value of an external input signal supplied via the external pin, selects one of a signal whose level value is set equal to a register value of the register and a signal whose level value is set opposite to the register value of the register, and outputs the selected signal as a control parameter signal. The register update circuit updates the register value of the register when a level value of the control parameter signal need be changed.

  • Patent number: 7533192
    Abstract: The invention provides a task scheduling method which can prevent overflowing of a buffer on a host system or a data encoding/decoding apparatus even when the transfer rate falls in case the compressed data and the non-compressed data are simultaneously transferred between the host system and the data encoding/decoding apparatus. In a task scheduling method, the compressed audio/video data is transferred from the buffer of the host system to an external device with a first transfer priority. The non-compressed audio/video data is transferred from the buffer to the external device with a second transfer priority lower than the first transfer priority.

  • Patent number: 7471722
    Abstract: A video encoding device capable of performing a near-real-time encoding process while restraining deterioration in image quality. A first encoding section encodes a video signal to generate a first stream and extracts stream information including space- and time- related information of the video signal. A stream buffer stores video scenes of the first stream which correspond to a partial time of the video signal. An encoding control section analyzes a code generation rate and motion information from the stream information to generate encoding control information. A second encoding section encodes the first stream read from the stream buffer, in accordance with the encoding control information, to generate a second stream. The stream buffer stores multiples video scenes of the first stream by means of which a scene change can be detected as an information rate change.
