Abstract:
1. A method for selecting a macroblock partition to transcode digital data with an arbitrary spatial resolution from a first video standard to a second video standard, the method comprising: a hardware decoder for decoding an input signal to generate the digital data, with the digital data being based on a single input signal; a hardware processor for processing the digital data corresponding to the first video standard, the processing comprising resizing and anti-aliasing the digital data; determining a plurality of partitions for a macroblock for transcoding the second video standard with an arbitrarily changed spatial resolution and without any motion estimation; generating at least one motion vector for a plurality of macroblock partitions so as to avoid motion estimation; determining a plurality of macroblock residuals for the plurality of macroblock partitions; selecting the macroblock partition and a macroblock encoding mode based on a minimum macroblock residual value selected from the plurality of macroblock residuals; and encoding the digital data based on the selected macroblock partition to the second video standard.
