20150030182 | ARRANGEMENT FOR MIXING AT LEAST TWO AUDIO SIGNALS - In order to realize a correction for changes in the reproduction loudness at low frequencies in a downmix-arrangement, a mixing arrangement is proposed for mixing at least two audio signals, which mixing arrangement is provided with a first unit ( | 01-29-2015 |
20140286508 | Interpolation Circuit for Interpolating a First and a Second Microphone Signal - An interpolation circuit for interpolating a first and a second microphone signal and for generating an interpolated microphone signal includes a first input ( | 09-25-2014 |
20140253699 | DISPLAY APPARATUS FOR DISPLAYING 3D IMAGES - Recent production methods for 3D video as a general rule generate stereo images in a same phase of movement. The left and right images of a stereo pair thus image the recorded (or rendered) scene at a same point of time. Correct reproduction consequently requires the two images to be shown concurrently. This is, however, not true for all apparatuses such as, for example, 3D television sets including the so-called shutter technology, which show the left and right images in temporal succession. This temporally offset reproduction of the two stereo images results in clearly perceivable image errors. The invention describes a method for compensating such image errors. This is achieved by interpolating the images of one of the channels. | 09-11-2014 |
20140218489 | TEST SIGNAL GENERATOR, TEST SIGNAL FOR 3D DISPLAY APPARATUSES, AND STORAGE MEDIUM HAVING A TEST SIGNAL STORED THEREON - Some 3D video display apparatuses reproduce the two stereo channels in a temporally offset manner, which may bring about the occurrence of interfering image errors. Appropriate dispositions allow to compensate such image errors entirely or in part. In the reproduction of 3D video it is not definitely possible to recognize whether, and in what form, such dispositions are being employed in a display apparatus. The invention discloses a test signal generator and a test signal which allow to examine the error compensation dispositions being employed. | 08-07-2014 |

20140169591 | Digital Switching Signal Sequence for Switching Purposes, Apparatus for Including Said Digital Switching Signal Sequence in a Digital Audio Information Signal, and Apparatus for Receiving the Information Signal Provided With the Switching Signal Sequence - A digital switching signal sequence is realized as a previously digitized, high-pass filtered white noise signal of a predetermined length T, with a high-pass cut-off frequency which lies above the frequency where the loudness threshold characteristic in silence of the human hearing has its highest sensitivity, if possible. The switching signal sequence is employed for switching purposes ( | 06-19-2014 |
20140132717 | METHOD AND SYSTEM FOR DECODING A STEREOSCOPIC VIDEO SIGNAL - A method and a system for decoding a stereoscopic video signal of the type including a sequence of composite frames each including a left image for the left eye and a right image for the right eye are disclosed. The method provides for detecting one or more edges inside at least one of the composite frames; determining a stereoscopic format of the video signal based on the edge detection; and extracting the right image and the left image based on the determined stereoscopic format. | 05-15-2014 |

20130318558 | INDOOR BROADCASTING METHOD AND SYSTEM - A method for distributing broadcast signals to an indoor environment, includes the steps of receiving ( | 11-28-2013 |
20130286886 | Method and System for Controlling Data Packet Transmissions Over Lossy Protocols - A method for data packets transmission includes a first group of data packets transmitted with a first bitrate, this first group including a first payload. Quality of transmission of the first group of data packets is checked and, if it is above a first threshold, a second group of data packets is transmitted with a second bitrate higher than the first bitrate. The second group of data packets includes a payload, and additional control data (C | 10-31-2013 |

20130063344 | METHOD AND DEVICE FOR THE REMOTE CONTROL OF TERMINAL UNITS - For the remote control of terminal units of consumer electronics and of computers by way of a remote control with integrated motion sensors, it is suggested to process the detected motion sequences in the remote control itself and interpret them as gestures to the effect that certain gestures correspond to certain commands which are transmitted from the remote control directly to the corresponding terminal unit or to a computer.

20120237055 | METHOD FOR DUBBING MICROPHONE SIGNALS OF A SOUND RECORDING HAVING A PLURALITY OF MICROPHONES - In order to compensate tonal changes arising from a multi-path propagation of sound portions during the mixing of multi microphone audio recordings as far as possible it is suggested to form spectral values of respectively overlapping time frames of samples of each a first microphone signal ( | 09-20-2012 |

20100146581 | METHOD FOR CONTROLLING SET TOP BOXES AND SET TOP BOX THAT CAN BE CONTROLLED BY SAID METHOD - The aim of the invention is to indicate the availability of an update for an MHP application, which is modified only periodically, to the user of a set top box, whilst helping him or her to decide whether the modified update is actually required and optionally still maintaining the availability of the older update without restrictions. To achieve this, information concerning the scope and/or type of modification in relation to the older version is provided in the transmitted version number for the modified MHP application. The set top box starts the saved older version if special information exists (“launchable with older version” flag) and permits a comparison of the version number with the received version number of the modified MHP application as to whether the modifications of the modified MHP application are of such significance that the modified version must be received and saved in the cache memory. If an update of the cache memory is required, the user of the set top box receives an indication to switch to the narrow-band transponder channel and to receive the modified MHP application. | 06-10-2010 |
20080285946 | Method and Arrangement for Retransmitting and Processing and/or Displaying and/or Storing of Sound and/or Picture Contents - A special instruction for not encoding a content is incorporated into access authorization data contained in the received signal, so that within a unified system for transmitting and receiving of encoded or non-encoded sound and/or picture contents, it is possible to meet the requirement of public broadcasting and “free-to-air” program providers for a non-encoded processing and/or display and/or storage of freely accessible contents for the end user. The instruction signalizes that the sound and/or picture contents, once received, must be available in the non-encoded form to the end user. The access authorization data remain added to the sound and/or picture contents, even in cases of a cascading, encoded retransmission, or remains logically linked thereto by suitable means, even if transmitted physically separate along with the picture and/or sound contents. During the processing and/or display and/or storage of the picture and/or sound contents retransmitted in the encoded form, the special instruction triggers a decoding of the picture and/or sound contents, at least at the end of the retransmission cascade. | 11-20-2008 |
