Embodiments described herein provide systems and methods for sharing encoder output of video streams. In a particular embodiment, a method provides determining video profiles for each of a plurality of devices. The method further provides determining if two or more of the video profiles are similar by determining if parameters associated with each video profile differ by less than a threshold value. The method further provides transmitting a video stream encoded in a single format to the devices if they have similar profiles and transmitting video streams encoded in different formats to the devices if they do not have similar profiles.

The present disclosure provides a data processing system and method. The method may include obtaining preliminary data. The method may also include generating first encoded data by compressing the preliminary data in a first encoding procedure. The method may further include determining whether a compression ratio of the first encoded data is below a compression threshold. The method may still further include generating second encoded data by compressing the preliminary data in a second encoding procedure in response to determining that the compression ratio of the first encoded data is below the compression threshold, wherein the first encoding procedure and the second encoding procedure are lossless compressions.

A method of encoding image data, including: frequency-transforming input image data to generate an array of frequency-transformed input image coefficients by a matrix-multiplication process, according to a maximum dynamic range of the transformed data and using transform matrices having a data precision; and selecting the maximum dynamic range and/or the data precision of the transform matrices according to the bit depth of the input image data.

A lossless data compression method that comprises the receiving of a series of data segments of a known length and a known characteristic and the pre-processing of the series of data segments to generate a series of differential data, which comprises a first value, one or more differential values and a last differential value. The method further comprises the dividing of the series of differential data into at least two blocks of differential data and the encoding of at least one block of differential data using Rice encoding, thereby providing at least one block of encoded differential data. In addition, the method comprises the generating of a data packet that comprises said at least one blocks of encoded differential data and any blocks of differential data not having been encoded.
