A multi-codec encoder includes a first partitioning unit and a second partitioning unit configured to receive first data and second data, respectively. Sequential frames of image data are alternately classified into the first data and the second data. The multi-codec encoder further includes a motion estimation module configured to generate motion estimation information, based on the first data and reference data, a first codec configured to encode the first data with the motion estimation information, and a second codec configured to encode the second data with the motion estimation information.

Multi-codec encoder and multi-codec encoding system including the same

An image processing device includes a frame buffer compressor, which is configured to: (i) compress source data into compressed data having CRC bits appended thereto, and (ii) decompress the compressed data into output data and use the CRC bits to check for errors in the output data. A multimedia device is provided, which is configured to generate the source data in response to raw data. A memory device is provided, which is configured to store the compressed data. The frame buffer compressor may include an encoder configured to compress the source data into the compressed data with the CRC bits appended thereto, and a decoder configured to decompress the compressed data into the output data. The encoder may include a prediction module, which is configured to generate prediction data including reference data and residual data, from the source data.

Image processing devices having enhanced frame buffer compressors therein

A method of decoding image data includes operating a decoder including a decoding buffer and a decoding module, wherein the decoding module includes a plurality of decoding channels, setting a non-shared memory region and a shared memory region in the decoding buffer, restoring a plurality of frames by decoding a bitstream using the plurality of decoding channels, determining a type of each of the frames, and writing each frame to one of the non-shared memory region or the shared memory region based on the type of each frame.

Method of operating decoder using multiple channels to reduce memory usage and method of operating application processor including the decoder

In one example embodiment, a multimedia codec includes a reader configured to read a first frame in an image group according to a field mode indicated by a mode selection signal, and produce a top field and a bottom field for the first frame. The multimedia codec further includes an encoding component configured to encode the top field in an intra mode and encode the bottom field in an inter mode.

Multimedia codec, application processor including the same, and method of operating the application processor

A method of operating an image processing according to an example embodiment includes generating a plurality of encoded bitstreams having different resolutions using an original image output from a video source, generating a plurality of restored images corresponding to the plurality of encoded bitstreams, respectively, the plurality of restored images having a same resolution as a first resolution of the original image, and outputting one of the plurality of encoded bitstreams, based on the plurality of restored images and the original image.
