By encoding the video data using a non-linear transformation between video codes and film density codes, the resulting film archive allows a film print to be produced at a higher quality compared to other film archive techniques. The characterization pattern contains spatial, temporal and colorimetric information relating to the video content, and provides a basis for recovering the video content from the film archive.08-01-2013
20120300124SIGNAL TRANSMISSION APPARATUS, SIGNAL TRANSMISSION METHOD, SIGNAL RECEPTION APPARATUS, SIGNAL RECEPTION METHOD, AND SIGNAL TRANSMISSION SYSTEM - A signal transmission apparatus includes: a vertical rectangular region sampling-out control section that obtains vertical rectangular regions, repeatedly performs a process where pixel samples read out from each line of class images are mapped to each line of video data regions of sub-images, maps pixel samples to each line of the video data regions, and repeatedly maps pixel samples to the next line; a line sampling-out control section that samples out the pixel samples every other line from each line of the sub-images to which the pixel samples have been mapped, so as to generate an interlace signal; a word sampling-out control section that samples out for each word the pixel samples which have been sampled out for each line so as to be mapped to video data regions of an HD-SDI prescribed by the SMPTE 435-2; and a readout control section that outputs the HD-SDI.11-29-2012
20120086851SIDE LOADING - Side loading of content elements is provided. A selection of a content element from a terminal device may be received and a content format associated with the terminal device may be identified. If the content element is not available in the identified content format, the content element may be transcoded from a current content format to the identified content format and the content element may be transferred to the terminal device in the identified content format.04-12-2012
20120086850SUPER RESOLUTION FROM A SINGLE SIGNAL - A method implementable on a computing device includes exploiting data redundancy to combine high frequency information from at least two different scales of an input signal to generate a super resolution version of said input signal. An alternative method includes exploiting recurrence of data from an input signal in at least two different scales of at least one reference signal to extract and to combine high frequency information from a plurality of scales of said at least one reference signal to generate a super resolution version of said input signal. An alternative method includes generating a super resolution version of a single input video sequence in at least the temporal dimension by exploiting data recurrence within the input video sequence or with respect to an external database of example video sequences. A signal may be an image, a video sequence, an audio signal, etc.04-12-2012
20130208182MEDIA BUILD FOR MULTI-CHANNEL DISTRIBUTION - According to one embodiment, methods and systems are disclosed for converting multi-media content to multiple deliverable formats using a conversion workflow. For example, a single source content file can be captured and a plurality of deliverable content files can be derived from the single source content file. Each of the plurality of deliverable content files can be in a format specific to a different distribution channel. That is, a single source media file can be used to automatically build one or more distribution files for a particular channel or channels. Furthermore, the distribution files can be built including logos, branding, open/close graphics, ratings, promo material, etc. The inclusion of these elements can be based on a common set of business rules defining, for example, what elements should be included in different types of distribution files.08-15-2013
