    摘要: A device for processing a first video signal and a second video signal that contain image data which overlap within a combined picture includes a processing element and a controller. The processing element receives the first video signal containing first image pixel data and receives the second video signal containing second image pixel data, and processes the first video signal and the second video signal to generate a third video signal indicative of an overlap region of images formed by the first and second video signals. The controller receives the first video signal, the second video signal, and the third video signal, and in response to a plurality of control signals selectively outputs one of the first, second and third video signals, wherein the third video signal is a weighted sum of the first and second video signals, wherein the control signals comprise a first control signal indicative of the location and size of a first image associated with the first video signal within a picture and a second control signal indicative of the location and size of a second image associated with the second video signal within the picture.

    摘要: A method for encoding first and second data words, which may represent differential data values (e.g., luminance and chrominance difference data values), onto an encoded data word includes determining a first approximation value, to which a first code word is assigned, for a first data value, and determining a second approximation value, to which a second code word is assigned, for a second data value; mapping the first and second code words onto first and second data segments, respectively, of the encoded data word; determining a first difference value between the first data value and the first approximation value and determining a second difference value between the second data value and the second approximation value; and at least partial mapping of a first difference data word representing the first difference value and/or a second difference data word representing the second difference value onto at least one additional data segment of the encoded data word. The first and second data values are represented by first and second data words, respectively, each containing a number of data bits. The first approximation value is formed in that a position is determined for the highest relevant data bit for the value of the first data word and the power of two is formed for this bit position. The second approximation value is formed in that a position is determined for the highest relevant data bit for the value of the second data word and the power of two is formed for this bit position. Each data bit position of the first data word is assigned at least one first code word that is individual to this bit position, and each data bit position of the second data word is assigned at least one second code word that is individual to this bit position. Each bit position of the first data word is assigned a first sequence number and each bit position of the second data word is assigned a second sequence number.
