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.

Selection of the maximum dynamic range of transformed data and the data precision of transform matrices according to the bit depth of input data

A data encoding method for encoding an array of data values as data sets and escape codes for values not encoded by the data sets, an escape code including a unary coded portion and a non-unary coded portion, the method including: setting a coding parameter defining a minimum number of bits of a non-unary coded portion; adding an offset value of 1 or more to the coding parameter to define a minimum least significant data portion size; generating one or more data sets indicative of positions, relative to the array of data values, of data values of predetermined magnitude ranges, to encode the value of at least one least significant bit of each data value; generating respective complementary most-significant data portions and least-significant data portions; encoding the data sets; encoding the most significant data portions; and encoding the least-significant portions.

Encoding and decoding of significant coefficients in dependence upon a parameter of the significant coefficients

A packet-based video network includes: plural packetized video data nodes; a packet switch configured to switch from one of video packet routes to another of video packet routes; and a video synchronizer configured to synchronize the video frame periods of at least nodes acting as packetized video data sources; wherein: each node acting as a packetized video data source is configured to launch onto the network packetized video data such that, for at least video frame periods adjacent to a switching operation: the node launches onto the network packetized video data required for decoding that frame during a predetermined active video data portion of the video frame period, and the node does not launch onto the network packetized video data required for decoding that frame during a predetermined remaining portion of the video frame period; and the switching operation is implemented during the predetermined remaining portion.

A method and a system for generating image content. The method and system allow segments of a panoramic scene, to be generated with reduced distortion. The method and system reduce the amount of distortion by mapping pixel data onto a pseudo camera focal plane which is provided substantially perpendicularly to the focal location of the camera that captured the image. A camera arrangement can implement the method and system.
