| 20120014526 | Method for Generating a Downward-Compatible Sound Format - A method of generating an audio output signal according to a downward compatible sound format, the method including: generating a sum signal by combining a first input channel signal with a second input channel signal; and dynamically correcting the sum signal using samples of the first and second input channel signals from overlapping time windows. | 01-19-2012 |
| 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 |
