Abstract: A method includes encoding a first message including first parameters for a first color transform that transforms a video signal into a first color-mapped video signal; encoding a second message including second parameters for a second color transform that transforms the video signal into a second color-mapped video signal; and encoding the video signal, the first message, and the second message in a video bitstream. A method includes decoding the video bitstream into the video signal, the first message including the first parameters, and the second message including the second parameters, and performing at least one of the following: displaying the video signal; transforming the video signal into the first color-mapped video signal by applying the first color transform and displaying the first color-mapped video signal; and transforming the video signal into the second color-mapped video signal by applying the second color transform and displaying the second color-mapped video signal.

Abstract: Systems and/or methods for estimating color conversion components. A video coding device may receive a picture associated with a first color space. The picture may comprise a first component at a first sampling location, a second component at a second sampling location and the second component at a third sampling location. The video coding device may apply a first interpolation filter to the second component at the second sampling location and the second component at the third sampling location to determine the second component at the first sampling location. The second component at the first sampling location may be associated with the first color space. The video coding device may apply a color conversion model to the first component at the first sampling location and to the second component at the first sampling location to translate the first component at the first sampling location to a second color space.

Abstract: A method, a programmed computer system, for example, a network-based hardware device, and a machine readable medium containing a software program for modifying a high definition video data stream in real time, with no visible delays, to add content on a frame by frame basis, thus simultaneously compositing multiple different customized linear views, for purposes such as creating and broadcasting targeted advertising in real time. The method employs conventional video processing technology in novel and inventive ways to achieve the desired objective by passing data selected by the program back and forth between a GPU and a CPU of a computer. The method is also usable with data streams having lower than high definition where real time processing is desired and yields better results than conventional methods. In such applications, all processing may be done by the CPU of a sufficiently powerful general-purpose computer.

Abstract: The present disclosure relates to devices comprising small form factor pluggable units (SFP) having connectors for receiving and sending signals and a processor for converting the received signals prior to sending the converted signals. Received or sent signals may comprise video signals in various analog or digital formats. Conversion of the received signals may comprise analog to digital or digital to analog conversion, serializing or deserializing a digital signal, frame synchronization of a video signal, and/or cross conversion of a video signal from a first format to a second format.

Abstract: An improvement information generating unit (11) generates a plurality of types of improvement information for improving the image quality of an image (broadcast image) broadcast as a program. An integrating unit (12) embeds one or more of the plurality of types of improvement information generated by the improvement information generating unit (11) into the broadcast image, thus integrating the improvement information with the broadcast image, and outputs an integrated signal. The integrated signal is transmitted via a transmitting unit (13). Thus, images of various image qualities are provided.
