An image processing device includes a multimedia IP including a plurality of IP cores, at least one of which processes image data to generate source data, a frame buffer compressor, shared by the plurality of IP cores, compressing the source data to generate compressed data, and a memory coupled to the frame buffer compressor and accessed by the multimedia IP through the frame buffer compressor so that the compressed data is stored in the memory. The frame buffer compressor includes a quantization module which performs quantizing on the source data to generate recon data and a prediction module which executes intra-prediction on the recon data to generate prediction data.

Two or more video signals from two or more sensors are received and discrete wavelet transformations are performed on the two or more video signals. Temporally stationary and non-stationary background data is determined from the discrete wavelet transformations. Redundancies are determined using the temporally stationary background data, the redundancies indicating an overlap between the two or more video signals Data of the two or more video signals is stored without the redundancies to reduce a storage size.

One particular implementation may take the form of a method and system for decoding 3-D multimedia content. In one example, the present invention may take the form of a method of decoding 3-D multimedia content encoded with at least content frames and null frames. The method may operate to receive the 3-D multimedia content, extract at least one content frame, at least one null frame, and display information. The method may further operate to reconstruct the content and null frames in a display-sequential manner using the display information to indicate the display order of the at least one content frame. In some examples, the method and system for encoding and decoding multimedia content may encode the multimedia content such that the at least one null frame may not be displayed by a display device.
