Abstract
The invention relates to a method for the transmission of additional information when using a method for compressing data by means of a prioritizing pixel transmission, said data consisting of individual pixel groups, each of which comprises a positional value within an image array and at least one pixel value. The minimum size of the image array is defined by the height (h) and the width (b) of an image, expressed in pixels. The invention is characterized by the fact that positional values which do not occur in the actual data but lie outside the range of the image array are used during the transmission of additional information.

Method for transmitting additional information when using a method for compressing data by way of a prioritizing pixel transmission, wherein the compressed data comprise individual pixel groups, with each pixel group having a position value within an image array and at least one pixel value, comprising the steps of:
- defining a minimal size of the image array by a height h and a width b of an image, expressed in pixels;
- transforming the data by compression;
- transmitting the compressed data and the additional information, wherein the additional information is placed at position values that do not occur in the data, and is located instead outside an area of the image array;
- reassembling the compressed data with the additional information;
- and
- displaying the reassembled data;
- wherein the additional information is transmitted in the form of textures and the additional information has a position value of height h×width b of the image array +k, wherein k is a predefined value that indicates that a texture is included.
Method for transmitting additional information when using a method for compressing data by way of a prioritizing pixel transmission, wherein the compressed data comprise individual pixel groups, with each pixel group having a position value within an image array and at least one pixel value, comprising the steps of:
- defining a minimal size of the image array by a height h and a width b of an image, expressed in pixels,
- transforming the data by compression;
- transmitting the compressed data and the additional information, wherein the additional information is placed at position values that do not occur in the data, and is located instead outside an area of the image array;
- reassembling the compressed data with the additional information;
- and
- displaying the reassembled data;
- wherein the additional information is identified as being associated with a certain document format.
Method for transmitting additional information when using a method for compressing data by way of a prioritizing pixel transmission, wherein the compressed data comprise individual pixel groups, with each pixel group having a position value within an image array and at least one pixel value, comprising the steps of:
- defining a minimal size of the image array by a height h and a width b of an image, expressed in pixels,
- transforming the data by compression;
- transmitting the compressed data and the additional information, wherein the additional information is placed at position values that do not occur in the data, and is located instead outside an area of the image array;
- reassembling the compressed data with the additional information;
- and
- displaying the reassembled data;
- wherein priorities are assigned to the additional information depending on its content-related relevance, its temporal relevance or its device-dependent relevance.
Method for transmitting additional information when using a method for compressing data by way of a prioritizing pixel transmission, wherein the compressed data comprise individual pixel groups, with each pixel group having a position value within an image array and at least one pixel value, comprising the steps of:
- defining a minimal size of the image array by a height h and a width b of an image, expressed in pixels,
- transforming the data by compression;
- transmitting the compressed data and the additional information, wherein the additional information is placed at position values that do not occur in the data, and is located instead outside an area of the image array;
- reassembling the compressed data with the additional information;
- and
- displaying the reassembled data;
- wherein the additional information is transmitted in descending order of its priority.
A method for transmitting image data and additional information by prioritized transmission of compressed image data, comprising the steps of:
- defining a minimal size of an image array by a height h and a width b, expressed in pixels,
- arranging the image data in pixel groups, with each pixel group having a commonly assigned prioritization level and a position value within the image array and at least one pixel value,
- arranging the additional information at position values outside the range of the image array,
- compressing a data stream including both the image data of the pixel groups at the position value within the image array and the additional information at the position values outside the range of the image array, and
- transmitting the compressed data stream by prioritized transmission from a transmitter to a receiver;
- reassembling the compressed data with the additional information;
- and
- displaying the reassembled data.
