  • Publication number: 20150010063
    Abstract: An image decoding method obtains pieces of coded data which are included in a bitstream and generated by coding tiles obtained by dividing a picture. The pieces of coded data are decoded to generate image data of the tiles. When obtaining the pieces of coded data, tile boundary independence information is further obtained from the bitstream. The tile boundary independence information indicates whether each boundary between the tiles is a first or second boundary. Image data of a first tile is generated by decoding a first code string included in first coded data with reference to decoding information of an already-decoded tile when the tile boundary independence information indicates the first boundary. The first code string is decoded without referring to the decoding information of the already-decoded tile when the tile boundary independence information indicates the second boundary.

  • Patent number: 8280178
    Abstract: A moving image receiving apparatus has a moving image decoding apparatus (303) for decoding received moving image data. The moving image decoding apparatus (303) comprises: a media buffer (401) for storing moving image data; an intra-map memory (402) for storing an intra-map indicating a location of an intrablock included in an interframe of the moving image data; a pseudo intraframe generator (404) that, based on an intra-map stored in the intra-map memory (402), extracts an image of an intrablock included in an interframe in order from a latest interframe accumulated in the media buffer (401), combines images of intrablocks extracted from a plurality of interframes, and thereby generates a pseudo intraframe; and a decoder (406) that starts to decode moving image data, using a pseudo intraframe. The moving image receiving apparatus can thus decode received moving image data from an arbitrary frame.

  • Patent number: 8275906
    Abstract: A switch instruction is transmitted from a PC terminal to a portable PC terminal; the portable PC terminal transmits a switch connection request to a portable communication terminal on the other end of communication; the portable PC terminal, when it is waiting for a response to the switch connection request and receives a switch connection request from the other end of communication, detects that switching processes are being performed simultaneously; upon detection of the simultaneous switching, a switching session related to either switch connection request is determined to be continued; the portable PC terminal, which received the switch connection request to which the switching session determined to be continued was related, transmits a success response including information on the switching process of the portable PC terminal side; and the PC terminal, which received the switch connection request to which the one to be stopped was related, transmits a failure response.

  • Patent number: 8179958
    Abstract: When a switching target device receives a media output indication from a sender device, a switch connects with contact B, which causes all image data stored in an extended media buffer to be inputted in a decoder, starting from the first frame (which is an I-frame) of the image data. The decoder decodes the image data, starting from the I-frame, and stores a reconstructed image in a reconstructed-image buffer. A reconstructed image required for decoding video picture data outputted from a media buffer is held in the reconstructed-image buffer. Thus, when device switching occurs, the decoder can immediately start decoding regardless of whether video picture data inputted from the media buffer is an intraframe.
