Multiple codec-imager system and method

#The present invention relates to data compression, and more particularly to compressing data utilizing wavelets.

#Video “codecs” (compressor/decompressor) are used to reduce the data rate required for data communication streams by balancing between image quality, processor requirements (i.e. cost/power consumption), and compression ratio (i.e. resulting data rate). The currently available compression approaches offer a different range of trade-offs, and spawn a plurality of codec profiles, where each profile is optimized to meet the needs of a particular application.

#2D and 3D wavelets are current alternatives to the DCT-based codec algorithms carried out by MPEG video distribution profiles. Wavelets have been highly regarded due to their pleasing image quality and flexible compression ratios, prompting the JPEG committee to adopt a wavelet algorithm for its JPEG2000 still image standard. Unfortunately, most wavelet implementations use very complex algorithms, requiring a great deal of processing power, relative to DCT alternatives. In addition, wavelets present unique challenges for temporal compression, making 3D wavelets particularly difficult.

#FIG. 1 illustrates a system for compressing data utilizing multiple encoders on a single integrated circuit.

#FIG. 2 illustrates a framework for compressing/decompressing data, in accordance with one embodiment.

#FIG. 3 illustrates a method for compressing/decompressing data, in accordance with one embodiment.

#FIG. 1 illustrates a system 100 for compressing data utilizing multiple encoders 102 on a single integrated circuit 104 (i.e. ASIC). As shown, a first encoder is embodied on the single integrated circuit 104 for encoding a first set of data. Moreover, a second encoder is embodied on the same single integrated circuit 104 as the first encoder for encoding a second set of data. Of course, more encoders may be embodied on the single integrated circuit 104 for similar purposes.

#In use, data is received in the single integrated circuit. The data is then encoded utilizing a plurality of encoders incorporated on the single integrated circuit.

#In one embodiment, data may be encoded utilizing multiple channels on the single integrated circuit. Moreover, the data may be encoded into a wavelet-based format.
