Abstract: An apparatus includes a compact table generator module and a storage medium. The compact table generator creates a compact code table having multiple code word groups arranged in one or more hierarchies. Each of these code word groups includes a group mask that corresponds to one or more code words in a variable length code table. The storage medium stores information regarding the code word groups, such as a group mask for each of the code word groups, and a code index for each code word in the variable length code table.

Abstract: A first filtering module filters actual pixel values in a first direction (e.g., vertically), and a second filtering module filters interpolated pixel values received from the first filtering module in a second direction (e.g., horizontally). Also, a third filtering module filters actual pixels in the second direction. A computation module is coupled to the first, second and, third filtering modules. The computation module generates quarter-sample interpolated pixel values. These values are based on combinations of pixel values selected from actual pixel values and interpolated pixel values received from the first, second and, third filtering modules.

Abstract: System or methods may include loading information associated with a window of pixels from memory into a matrix of processing elements, the window of pixels being selected from a plurality of pixels associated with a reference frame, determining a current frame comprising a plurality of pixels, determining a first block of pixels from the plurality of pixels of the current frame, comparing each pixel of the first block of pixels to each pixel of the window of pixels by comparing the first block of pixels to portions of the window of pixels in an exhaustive manner, wherein comparing comprises calculating a first deviation result for each pair of compared pixels and aggregating the first deviation results for each position of the first block of pixels in the window of pixels, the calculating being performed by the matrix of processors.

Abstract: A method of decoding a stream of compression-encoded image data. The method includes supplying at least two values to an adder. At least one of the values is determined based at least in part on a type of a current syntax element in the stream of compression-encoded image data. The method also includes adding the at least two values at the adder to produce an index value. The method further includes using the index value to access a look-up table.

Abstract: A binary arithmetic decoding apparatus includes first, second and third pairs of look-up tables and first, second and third multiplexers. The first multiplexer selects between the respective outputs of the two look-up tables of the first pair of look-up tables. The second multiplexer selects between the respective outputs of a first look-up table of the second pair of look-up tables and of a first look-up table of the third pair of look-up tables. The third multiplexer selects between the respective outputs of a second look-up table of the second pair of look-up tables and of a second look-up table of the third pair of look-up tables. The three multiplexers are controlled in common.

An index value may be output based on the second address in the table.

Abstract: Systems are provided for converting high definition pictures or data to lower definition images using wavelet transforms. In the preferred embodiments, the wavelet transforms are be used in either the transmission/coding or reception/decoding phase for enabling a more efficient conversion of the signal and providing a more robust and accurate output. The wavelet transforms may be applied to conventional systems to enhance performance or entire transmission and reception systems may be designed where the wavelet transforms are applied to the data for coding, decoding and decimation operations.
