Provided is an encoding/transmitting apparatus used to transmit moving-picture data from a transmitting side to a receiving side and to subject the moving-picture data to streaming in the receiving side. The apparatus has an external-output request determining unit that monitors a state of a network. If the network assumes an undesirable state, a multiplex output unit stops multiplexing data. When the network assumes a good state, the multiplex output unit starts multiplexing the data again. A video encoding unit and an audio encoding unit keep encoding data, whether the multiplex output unit is multiplexing data or not. When the area occupied by encoded data in an encoded-video-data storage unit and the area occupied by encoded data in an encoded-audio-data storage unit exceed a predetermined value, the video encoding unit and audio encoding unit stop encoding data, and wait until the area occupied by encoded data sufficiently decreases.

Encoding/transmitting apparatus and encoding/transmitting method

There is provided an image processing device including an image acquisition part acquiring an image; a depth acquisition part acquiring a depth associated with a pixel in the image; a depth conversion part converting the depth in accordance with a function having a characteristic to nonlinearly approach a predetermined value with an increase in the depth; and a storage part storing the converted depth in association with the image.

This invention relates to an encoding/transmitting apparatus that is used to transmit moving-picture data from a transmitting side to a receiving side through a transmission path and to subject the moving-picture data to streaming in the receiving side. The apparatus has an external-output request determining unit () that monitors the state of a network. If the network assumes an undesirable state, the unit () causes a multiplex output unit () to stop multiplexing data. When the network assumes a good state, the unit () starts multiplexing the data again. A video encoding unit () and an audio encoding unit () keep encoding data, whether the multiplex output unit () is multiplexing data or not. When the area occupied by encoded data in an encoded-video-data storage unit () and the area occupied by encoded data in an encoded-audio-data storage unit () exceed a predetermined value, the units () and () stop encoding data, and wait until the area occupied by encoded data sufficiently decreases.

A method and apparatus for generating a dense depth map. In one embodiment, the method includes applying a joint bilateral filter to a first depth map to generate a second depth map, where at least one filter weight of the joint bilateral filter is adapted based upon content of an image represented by the first depth map, and the second depth map has a higher resolution than the first depth map.

A method and apparatus for performing a blur rendering process on an image is disclosed. In one embodiment, the method of performing a blur rendering process includes accessing a filtered image and depth map information, determining a plurality of blending coefficients for computing a weighted sum for the image and filtered image, wherein the plurality of blending coefficients define a substantially smooth transition from at least one first depth class to at least one second depth class and a substantially sharp transition from the at least one second depth class and the at least one first depth class, wherein the at least one first depth class and the at least one second depth class form at least a portion of a plurality of depth classes and combining the image and the filtered image into a resulting image using the plurality of coefficients.

A demultiplexer for separating different format packets from a multiplexed data stream. Each packet format has a different type of header which is analyzed based on micro-codes read out in sequence from a command memory. By using micro-codes, the demultiplexer minimizes the circuitry required to process multiple formats (e.g. digital video broadcasting (DVB), digital satellite system (DSS), and digital versatile disc (DVD)). The packets are separated and sent to their respective destinations based on the packet ID read from each header.
