摘要:
A video image data encoder comprises an input to receive stereoscopic image data. The stereoscopic image data includes first and second image data having chronological correspondence. An error correction encoding unit combines portions of the first image data and corresponding portions of the second image data from the input unit into a common encoding matrix. An error correcting code derived from the combined portions is added to the encoding matrix.
摘要:
A communication device including circuitry configured to receive communication data transmitted/received between a transmitting device and a receiving device that is a transmission target of transmission data transmitted by the transmitting device by unicast, to determine whether data to be used for a process by the communication device is included in the received communication data, and to process the data to be used for the process by the communication device when the circuitry determines the data to be used for the process by the communication device is included in the received communication data. The circuitry is also configured to prevent the communication device from responding to the transmitting device, and to not relay the communication data received from the transmitting device to the receiving device, when the circuitry determines the data to be used for the process is included in the received communication data.

An information processing apparatus which sends image data subjected to line based wavelet transformation to another device is disclosed. The apparatus includes: a storing means for splitting the image data supplied in units of precincts that are the set of lines to be a unit of processing for the line based wavelet transformation for every frequency component, and storing a plurality of precincts of image data for every frequency component; a packetizing means for reading and packetizing the plurality of the precincts of image data stored by the storing means for each of the frequency components; and a sending means for sending the plurality of the precincts of image data packetized by the packetizing means for each of the frequency components to the another device.

An information processing apparatus includes bank overflow flag confirming means for confirming whether a bank overflow flag is set, the bank overflow flag notifying the occurrence of a bank-full state where, in a storage area including plural banks formed therein to store data, not-yet-read data is stored in all the banks, read pointer control means for, upon confirming that the bank overflow flag is set, moving a location designated by a read pointer cyclically designating each of the banks as a bank, from which the data is to be read, to a bank positioned next to a bank at a location designated by a write pointer cyclically designating each of the banks as a bank, into which the data is to be written, and reading means for reading the data from the bank designated by the read pointer after the location designated by the read pointer has been updated.
摘要:
Access control based on CSMA is favorably carried out with the RTS/CTS method used together.If the RTS/CTS procedure is used together, CTS information is transmitted in response to the reception of RTS information, and data is transmitted in response to the reception of CTS. The CTS transmitting station measures the quality of RTS receive signal, and thereby determines a transmission rate at which it can receive and notifies a station as the destination of CTS. The station as the destination of CTS transmits data in response to CTS information. As the transmission rate for this data, the transmission rate indicated in the RATE field in CTS is applied.

摘要:
There is provided a communication apparatus including a communication unit that receives first communication data transmitted from a transmitting apparatus to a first receiving apparatus through unicast and second communication data transmitted from the transmitting apparatus to a second receiving apparatus, respectively and a processing unit that processes processing data included in the received first communication data and second communication data. When there is missing data in either of first processing data included in the first communication data and second processing data included in the second communication data, the processing unit executes processing using the other processing data in which there is no missing data, and the processing unit does not make the communication unit transmit a reply with respect to external apparatuses.

摘要:
A multi-carrier signal transmission apparatus transmits a transmission stream including at least preamble information necessary for synchronizing a transmission signal and data information as a multi-carrier signal. A modulator generates a transmission symbol stream by modulating an arrangement of the preamble information and the data information. A symbol expanding portion expands the transmission symbol stream on a frequency axis by generating a complex conjugate value of at least one part of the preamble information symmetrically on the frequency axis.

There is provided a receiving apparatus including a header detection section that receives image data encoded per a coding unit corresponding to N (N is equal to or greater than 1) lines in one field and detects control information to decide a decoding start point of the image data from a header attached to the image data, a storage section that stores the image data in each storage area assigned per the coding unit, a decoding start instruction section that decides a decoding start point of the image data based on the control information detected by the header detection section and, after waiting till the decoding start point, instructs a start of decoding per the coding unit, and a decoding section that decodes the image data stored in the storage section per the coding unit after the instruction to start decoding being received from the decoding start instruction section.
