Abstract: Encoded data using reversible variable length code words is input to a forward decoder (123) to be decoded in the forward direction. When an error is detected in the encoded data in the forward decode processing, backward decode processing is started by a backward decoder (126). A decode value determination unit (125) determines a decode value by using the forward and backward decode results and the error detection positions in the encoded data in units of bits and syntax which are respectively detected in the forward decoding and the backward decoding.

Abstract: An output coding apparatus includes a coder for coding an inputted bitstream to an error correction and/or detection code composed of information bits and check bits; and a bitstream assembling section for assembling an outputted bitstream by inserting a synchronization code at any one of a plurality of synchronization code insertion positions previously determined in the outputted bitstream, arranging the information bits at any desired positions of the bitstream, and by arranging the check bits at positions other than the synchronization code insertion positions in the bitstream. Therefore, when the coding apparatus is combined with a resynchronization method using both an error correction and/or detection code and a synchronization code, it is possible to solve a problem caused by pseudo-synchronization or synchronization-loss pull-out or step-out due to erroneous detection of the synchronization code.

Abstract: A pressure buffer of an ink-jet recording apparatus is placed in the vicinity of an ink-jet recording head in an ink supply path connecting an ink container to the ink-jet recording head. A body of the pressure buffer has a concave portion at least on one surface, and a flexible film is attached to tightly close the concave portion to form a chamber. The chamber has an ink flow outlet through which ink flows from the chamber to the ink-jet recording head and an ink flow inlet through which ink flows from the ink container to the chamber. The ink flow outlet is always positioned in an uppermost portion in a vertical direction of the chamber, and the ink flow inlet is positioned at an equal level or on a lower side in a vertical direction with respect to the ink flow outlet.

Abstract: A video encoding apparatus is provided with a resolution converting section, an encoding section, and a transmitting section. The resolution converting section enlarges or reduces a binary picture which represents the shape of an object. The encoding section encodes a binary picture reduced by the resolution converting section. The reduction ratio used by the resolution converting section is encoded, and the transmitting section transmits this encoded reduction ratio along with encoded data on the binary picture. The amount of encoded data produced from the encoding section is controlled by changing the enlargement/reduction ratio used by the resolution converting section.
