A device includes an analysis component to analyze NAL units of compressed video data representing a motion video to identify a GOP refresh, and to compare a period of time represented by frames of the motion video following the GOP refresh to a maximum; a division component to divide the compressed video data at a first point coincident with the GOP refresh to define a start of a compressed video portion, and at a second point to define an end of the compressed video portion to include frames of the motion video representing a shorter period of time between the first and second points than the maximum; and an assignment component to assign the compressed video portion to a transcoding device. Other embodiments are described and claimed.

Abstract: Disclosed are various embodiments directed to transcoding a media file in parallel. A media file may be accessed, the media file comprising a bit stream expressing a series of pictures. A first random access point in the bit stream and a second random access point in the bit stream are identified. An input segment of the bit stream is generated, the input segment comprising a starting point, the starting point being the first random access point. One of a plurality of transcoders is selected to transcode the input segment for generating a corresponding output segment, each transcoder being configured to operate concurrently in parallel. The output segment is stored in a memory.

In accordance with one embodiment, a method for determining the insertion points includes parsing the first video into a plurality of shots. The plurality of shots includes one or more shot boundaries. The method then determines one or more insertion points by balancing a discontinuity metric and an attractiveness metric of each shot boundary.

Abstract: In an image pickup apparatus, image data obtained by an image pickup unit is subjected to predetermined image processing, and an image is displayed on an electronic viewfinder screen based on the image data that has undergone the image processing. A specified color is determined based on color information included in a predetermined region of an image that is currently being displayed on the electronic viewfinder screen, and image processing parameters are produced so that color conversion is carried out on the image while eliminating color components of colors other than the determined specified color.

Abstract: An environment-compliant image display system, image processing method and information storage medium which can reproduce the same colors at different locations by absorbing any difference in the visual environment. In an individual environment, an image data is generated by absorbing any difference between a reference environment and the individual visual environment by a colored light information processing section 140, based on X, Y and Z values of an image in an image display area measured by a colored light sensor 60 as well as X, Y and Z values measured in the reference environment. A profile for projector input/output is corrected by a profile managing section 130 and then an image is projected by using an L/V drive section 190.

Abstract: A hardware-implemented screen-saver prevents burn-in of an image displayed on a screen of a display product by automatically reducing the video gain, and therefore the contrast, of the image when the portion of the image within a two-dimensional detection window has changed by less than a predetermined amount for a predetermined period of time. A lack of change of the incoming video signal of the image is detected and used to invoke a reduction in contrast of the image displayed on the display product. This allows the image to remain visible, yet reduces the possibility of burn-in of the image in the screen of the display product.

Abstract: A method is proposed for processing transitional regions in a picture signal. The picture signal comprises a sequence of digital pixel values. A number of adjacent pixel values, which contain a processing pixel value, are combined to form a processing block. A corrected pixel value is calculated for the processing pixel value. The maximum and minimum pixel values are first determined in the processing block to define the transitional region. The transitional region is then split into a number of sections on the basis of the magnitude of pixel value. Finally, a determination is made as to the section in which the processing pixel value is located. The processing pixel value is allocated a corresponding correction value in order to increase, to reduce or to leave unchanged the processing pixel value, in accordance with a predetermined transfer function.
