Abstract: A digital steganography system comprises a message sender in electronic communication with a message receiver through a social media platform. The message sender uses a compute device configured to conceal a secret digital message in the semantic components of a digitally synthesized image which is uploaded onto the social media platform and published in a social media post. As part of the message encoding process, the compute device for the message sender coverts the digital message into binary code, applies encryption and error-correction algorithms, and then implements image synthetization operations to yield the digitally synthesized image. The message receiver is provided with a compute device configured to identify the social media post, automatically download the synthesized image, and apply an inverse set of the image synthetization operations to yield binary code which is subsequently decoded and decrypted in order to extract the original covert message.

Abstract: Technologies directed to providing multimedia service over an extended range Wireless Local Area Network (WLAN) (e.g., IEEE 802.11ah) are described. In one method, a first wireless device identifies a first portion of media data as having a first priority value and a second portion of the media data as having a second priority value that is less than the first priority value. The first wireless device modulates the first portion to obtain first modulated data using a first modulation and coding scheme (MCS) that has symbol repetition and modulates the second portion to obtain second modulated data using a second MCS in which there is no symbol repetition. The first wireless device sends the first modulated data to a second wireless device in the wireless network and sends the second modulated data to the second wireless device after sending the first modulated data.

Abstract: One configuration as discussed herein includes a data processor acting as streaming server for providing streaming media from a repository to a decoder. The data processor retrieves reconstruction data and corresponding stream metadata from a repository, the reconstruction data encoded in accordance with a tiered hierarchy including multiple levels of quality. The data processor transmits selected portions of the reconstruction data to one or more decoder resources. The decoder resources reconstruct renditions of portions of a signal such as images/frames based on the transmitted portions of reconstruction data. During the transmission step, the data processor may vary a level of quality of the reconstruction data retrieved and transmitted to the decoder resource. The decoder resources decode the received reconstruction data to play back the signal at different levels of quality.

Abstract: At the transmitter side, carrier waves are modulated according to an input signal for producing relevant signal points in a signal space diagram. The input signal is divided into two, first and second, data streams. The signal points are divided into signal point groups to which data of the first data stream are assigned. Also, data of the second data stream are assigned to the signal points of each signal point group. A difference in the transmission error rate between first and second data streams is developed by shifting the signal points to other positions in the space diagram expressed at least in the polar coordinate system. At the receiver side, the first and/or second data streams can be reconstructed from a received signal. In TV broadcast service, a TV signal is divided by a transmitter into, low and high, frequency band components which are designated as a first and a second data streams respectively.
