Method for transferring additional information during fractal encoding of image. RU patent 2292662.

$Method for transferring additional information during fractal encoding of image. RU patent 2292662.$

FIELD: electric communications, namely, communications with decreased excessiveness of transferred information.

SUBSTANCE: in accordance to method, during encoding of image by means of method of fractal compression, into lower bits of domain indexes, additional information is inserted. To remaining bits of indexes of source image domain, sample inversion procedure is applied. After building in additional information and optimization of domain indexes these data together with information about domain orientation indexes, brightness and contrast are transferred via communication channel. At receiving side, additional information is separated and original image is restored.

EFFECT: transfer of additional information.

Method and device for command transfer / 2285352
In accordance to method, watermark is formed, containing inbuilt control command, which should be executed by device being controlled, control command being related to representation of advertisement, signal is generated, containing watermark, inbuilt in information block represented by it and transferred into device being controlled, generated signal is transferred with watermark into device being controlled for showing advertisement to user by executing control command, related to showing advertisement, user is questioned to determine his preferences and on basis of questioning user profile is generated with consideration of sales data for devices being controlled, product identification is added to control command, while control command contains value of parameter, specific for advertisement, while device being controlled receives advertisement, wherein parameter values are used.

Communication system, transmitter, receiver and method for using a descriptor of data being saved / 2280960
Communication system provides identification of multiply used data in transmitter by means of data descriptors, inserted into data stream being transferred from transmitter to receiver, data stream, being received at receiving end, is analyzed to detect presence of data descriptors, which signify presence of multiple use data, when such a descriptor is detected, it is locally saved at receiver level jointly with data to which it is related, and multiple use data saved in such a way may be utilized not only immediately after receipt at receiving end, but also later, without need to request transmission from the transmitter.

$Method for transmitting additional information during combined usage of vector quantization and fractal encoding of images$ Method for transmitting additional information during combined usage of vector quantization and fractal encoding of images / 2313917
In accordance to the invention, during encoding of image by means of combined usage of vector quantization and fractal compression method, additional information is integrated into lower bits of domain indexes or code book blocks. Testing inversion procedure is applied to remaining bits of domain indexes of original image or code book blocks. After integration of additional information and optimization of domain indexes and code book blocks, these data together with information about indexes of their orientation, brightness and contrast coefficients are transferred through a communication channel. At receiving side, additional information is extracted and original image is restored.

Import control of content / 2324301
Method for controlling import of content into a domain comprising number of devices consists in checking for the presence of a domain watermark in the content, and if the domain watermark is found in the content, refusing import of the content into the domain, and if the domain watermark is not found in the content, allowing import of the content into the domain and causing the domain watermark to be embedded into the content. Optionally, re-importing into the "original" domain might be allowed. The method further comprises refusing import of the content into the domain if the domain watermark is found in the content unless the identifier matches an identifier for the domain. Other payloads in the domain watermark can be used to e.g. implement location- or time-based restrictions on import.

Method of signal transmission with time slotting parameters in service information / 2325781
Said utility invention relates to a method of signal transmission in a digital television network. The ground digital television network is used for the transmission of IP datagrams to receiving devices using multiprotocol encapsulation (MPE). MPE datagram sections and, if using the forward error correction (FEC), MPE FEC datagram sections are transmitted in time-slotted packet signals. The time slotting parameters determining the minimum time between packet signal transmissions, and data output from the time slotting buffer of the receiving device at the transmission bit rate are used to save power and enhance the quality of service.

$Method of transmission of additional data in combined use of vector quantisation and fractal conding of images allowing for classifications of domains and units from code book$ Method of transmission of additional data in combined use of vector quantisation and fractal conding of images allowing for classifications of domains and units from code book / 2327301
Invention relates to communication, in particular, to reducing the message redundancy. The developed method allows transmitting additional data without increasing the volume of transmitted data with the transmission rate left intact. First, the initial image is separated into not overlapping range units to be classified. Here, note that every range unit is refereed to one of the three classes, and the said classification is applied to the domains and units from the code book as well. Additional data is entered into lower category of the domain or units indices, to the rest categories of indices of the domain of the initial image or units from the code book applied is the trial inversion procedure. Now, the domain indices and units from the code book are optimised to be transmitted, along with the data on indices of their orientation, over the communication channel. The receiving party isolates the additional data and restores the initial image.

Water-mark indication of signal with bits variable flow / 2327302
Invention relates to the devices and methods for implementation and detection of water-marks in information signals. One proposed method and device of water-mark implementation in information signal (MPin), when administration of water-mark implementation process is fulfilled with, at least, one parameter of implementation. Implementation parameter value depends on transfer bit speed on information signal (MPin), and, at least, water-mark signals stability and its observability.
