Patent number: 7426187Abstract: This invention describes a false sync code protection (FSP) decoding technique by software for removing padding binary numbers from video data signals in electronic devices such as camera-phones. These padding binary numbers (e.g., a byte 101001012) are encoded in the video data signal. The invention describes a fast method for carrying out the decoding process using a predetermined criterion without need for separately comparing the received data using bit-by-bit process, and thus significantly reducing the number of processor instructions compared to the conventional bit-by-bit method. For the presented example these instructions are executed for every stand-alone zero byte found within e.g. JPEG data, which leads to considerable savings in execution time, especially if several JPEG images are taken and processed consecutively.Type: GrantFiled: October 21, 2003Date of Patent: September 16, 2008Assignee: Nokia CorporationInventor: Timo Kaikumaa

Publication number: 20070266408Abstract: A recording apparatus includes a recording unit, a determination unit, a generation unit, an identification unit, and a control unit. The recording unit records image data on a recording medium. The determination unit determines plural recording media to be allocated to a same group. The generation unit generates order information indicating an order of each recording medium in the group. The order information includes identification information identifying each recording medium. The identification unit identifies a recording medium in the group based on the identification information. The control unit controls the recording unit to record, on each of the plural recording media belonging to the same group, information representing an order of the identified recording medium in the group and information representing a total number of the recording media belonging to the same group, based on an identification result obtained by the identification unit and the order information.Type: ApplicationFiled: May 4, 2007Publication date: November 15, 2007Applicant: CANON KABUSHIKI KAISHAInventor: Kengo Takeuchi

Patent number: 7263713Abstract: In a television signal transmission system, CS broadcasting signals received via a master antenna are converted into intermediate frequency signals in an LNB (Low Noise Block Down Converter). The CS intermediate frequency signals then undergo conversion of the modulation format, for example, from QPSK into 64-QAM, so that CS broadcasting signals from each transponder, having a bandwidth of, for example, 27 MHz, are accommodated in a narrower bandwidth, for example, 6 MHz, which is equivalent to one channel of terrestrial broadcasting services. Then, the signals accommodated in the narrower bandwidth is frequency-shifted into a vacant frequency band in the VHF band or the UHF band. Accordingly, the CS signals accommodated in the narrower band and frequency-shifted into the vacant band are multiplexed with terrestrial broadcasting signals in the VHF and UHF bands and BS intermediate frequency signals so that all these signals are delivered to each household via a single cable.Type: GrantFiled: February 26, 2001Date of Patent: August 28, 2007Assignee: Sony CorporationInventors: Katsumi Oishi, Keiji Fukuzawa, Kenji Inose

Patent number: 7149470Abstract: A direct broadcast system receiving a plurality of broadcast signals within a direct broadcast receiver having an outdoor unit (ODU) is provided. The ODU includes a first low noise block (LNB) and a second LNB. The first LNB has a housing and amplifies a first broadcast signal. The second LNB amplifies a second broadcast signal. The ODU is electrically coupled to an integrated receiver and decoder (IRD). The IRD transmits a selection signal to the ODU. The first LNB and the second LNB are electrically coupled to a plurality of selection switches within the housing. The plurality of selection switches switch between the first LNB and the second LNB in response to the selection signal. A method of receiving a plurality of broadcast signals within a direct broadcast receiver is also provided.Type: GrantFiled: April 4, 2002Date of Patent: December 12, 2006Assignee: The DirecTV Group, Inc.Inventors: Dipak M. Shah, James R. Butterworth

Patent number: 7143132Abstract: A method and system are disclosed for reliably distributing file data from a single server to multiple client computers using a cyclical multicast approach. By “cyclical,” it is meant that data is distributed repeatedly onto the network at a certain period. The server transmits metadata asynchronously onto the network via a first communication channel, and file data via a second communication channel. Both data sets are received by one or more client devices operating a data catch module, which listens for metadata and file data from the network via a first and second communication channel. Once the metadata is received, the first channel is disconnected, and the one or more client devices operating the data catch module listen for file data for which the metadata is associated. Any file data not received during one cycle can be received by the client device in a subsequent cycle.Type: GrantFiled: May 31, 2002Date of Patent: November 28, 2006Assignee: Microsoft CorporationInventors: Eitan Klein, Anthony Blumfield
