  • Publication number: 20150146780
    Abstract: The video encoder includes: a refresh boundary determination unit which determines a position of a boundary in a second picture to be encoded based on a position of a boundary between a refreshed region and an unrefreshed region in a first picture which have been encoded and a refresh update size; and a restriction block identification unit which identifies, as a first restriction target sub-block which does not utilize a prediction vector, a first sub-block being a unit of motion compensation which is included in a refreshed region of the second picture and is possible to select a motion vector of a sub-block in the unrefreshed region of the first picture as a prediction vector of the motion vector, based on the positions of the boundaries of the first and the second pictures.

  • Patent number: 8798162
    Abstract: An encoding method includes encoding moving image; determining whether an information amount of the encoded moving image data in units of a picture satisfies a threshold to control a virtual buffer obtained by virtually modeling a reception buffer of a decoding device that is a transmission destination of the encoded moving image data; and setting, by dividing a picture included in the encoded moving image data, a decoding time for each divided picture to cause the decoding device to decode each divided picture when the determining determines the information amount of the encoded moving image does not satisfy the threshold to control the virtual buffer.

  • Patent number: 8767819
    Abstract: An encoding circuit (1) encodes an input image. A thinning-out decision unit (2) determines whether or not a picture needs to be thinned out. A dummy picture storage device (4) stores a dummy picture. A dummy picture is encoded data in which all the blocks refer to the same picture, motion vectors of all the blocks are zero, and none of the blocks has prediction residual information. A reference picture selection unit (5) selects a reference picture from among a plurality of referenceable pictures. A header generating unit (7) generates a header to be added to a dummy picture. In the header, the selected reference picture is assigned to an index specifying a reference picture for the dummy picture.

  • Patent number: 8605792
    Abstract: A coding apparatus is for performing a deblocking filter process by dividing input moving image data into frames, and coding the moving image data by dividing the frames into macroblock lines and by shifting and changing, for each frame, a refresh area in which an amount of coding information allocated to a specific macroblock line is larger than that of another macroblock line. The coding apparatus includes a determining unit that determines that a refresh area in a current frame as well as a macroblock line in the current frame corresponding to a macroblock line that will become a refresh area in a frame being subsequently subjected to the coding process becomes a next refresh area. The coding apparatus includes a coding unit that codes the refresh area and the next refresh area by allocating a larger amount of coding information than an amount allocated to the other macroblock line.

  • Patent number: 7974479
    Abstract: An encoding apparatus encodes a picture by inserting an intra-refresh area into a portion of the picture periodically based on an intra-refresh period. An encoding-status monitoring unit monitors an encoding status of the picture. A refresh-area control unit changes at least one of the intra-refresh area and the intra-refresh period based on the encoding status monitored by the encoding-status monitoring unit.
