Abstract: To provide a video conferencing system that a user can continue to use even when the user leaves for a different location. The video conferencing system includes: a takeover information generation unit which generates takeover information including configuration information on a screen layout used in a video conference held between a first video conferencing apparatus and a second video conferencing apparatus; a sending unit which sends the takeover information; a receiving unit which receives the takeover information; and a takeover setting unit which sets a screen layout of the third video conferencing apparatus using the takeover information received by the receiving unit, so that the third video conferencing apparatus takes over the screen layout and has the video conference with the second video conferencing apparatus after participation of the third video conferencing apparatus in the video conference is approved.

Abstract: A moving picture coding method in which the position of a current I-slice for a current picture is shifted in the vertical direction of the current picture, and which includes (i) performing inter coding on a first P-slice without using a motion vector (Sa1), and (ii) performing intra coding on a second P-slice using a motion vector (Sa2); the first P-slice is included in a first region that is adjacent to the current I-slice in the direction opposite to the forward direction for the shift in the vertical direction, and the second P-slice is included in a second region that is other than the first region within the current picture.

Abstract: An image decoding device and an encoding device include an arithmetic unit for performing arithmetic processing, an arithmetic data storage unit for storing an arithmetic result by the arithmetic unit, an input selection unit for selecting whether to read pixel data that is to be inputted to the arithmetic unit from compressed image data or from pixel data stored in the arithmetic data storage unit, and inputting the read pixel data to the arithmetic unit, and an arithmetic control unit for controlling, based on a transform mode used and the number of arithmetic operations in the arithmetic unit, a destination from which the pixel data that is to be inputted to the arithmetic unit by the input selection unit is read as well as a combination of pieces of pixel data targeted for the arithmetic processing by the arithmetic unit and multiplier coefficients for the arithmetic processing.

Abstract: To provide a video conferencing system that a user can continue to use even when the user leaves for a different location. The video conferencing system includes: a takeover information generation unit (5109) which generates takeover information including configuration information on a screen layout used in a video conference held between a first video conferencing apparatus (5100) and a second video conferencing apparatus (5200); a sending unit (5111) which sends the takeover information; a receiving unit (5312) which receives the takeover information; and a takeover setting unit (5324) which sets a screen layout of the third video conferencing apparatus (5300) using the takeover information received by the receiving unit (5312), so that the third video conferencing apparatus (5300) takes over the screen layout and has the video conference with the second video conferencing apparatus (5200) after participation of the third video conferencing apparatus (5300) in the video conference is approved.

Abstract: There is provided a packet processing device for, when decoding variable length data that is split into packets, realizing a reduction in processing load at a decoder, by providing information for identifying a start position of the data. A header analyzing section (11) determines whether data stored in a packet is start data containing start information or other data. A data extracting section (12) extracts data from a packet and stores the data in a buffer (13). A buffer controlling section (14) causes a start position memory (15) and a number-of-starts counter (16) to retain an address position and the number of start data stored in the buffer (13). A decode section (20) refers to the start position memory (15) and the number-of-starts counter (16) and executes a decode process for the data stored in the buffer (13).
