| 20100118933 | REFERENCE PICTURE LIST MANAGEMENT - A change to the high level syntax of the H.264/MPEG-4 AVC based Multiview Coding standard is made to allow for efficient management of the reference pictures lists. The invention allows for inter-view reference pictures to be duplicated in the final reference list by modifying the equation that is used to select the index of the inter-view picture that is to be added to the reference list. Duplication of a reference picture is valuable when a modified version of the reference picture is used as a reference picture along with the original reference picture, such as in weighted prediction and adaptive reference filtering.

| 20100115384 | METHOD FOR PACKET-SWITCHING TRANSMISSION OF MEDIA DATA AND DEVICE FOR PROCESSING MEDIA DATA - The invention relates to a method for packet-switching transmission of media data and a device for processing media data. Media data may be video, audio or text data, or other data. Transmission of the data is usually effected according to a streaming method. The data is therein transmitted in packets and re-assembled in the receiving device. For Internet applications, the real-time transport protocol is very widely used in the transmission of data streams. However, this data transmission protocol does not enable a secure transmission which is based on a repetition of the defectively transmitted data. Sequence counters are used according to this protocol so that left-out data packets can be detected in the receiving device. According to the invention, it is provided that error information data is inserted in the destination media data record which is generated from the received data in the receiving device when, according to the transmission protocol, transmission errors are detected in the analysis of the data packets received. The transmission errors are then documented in the destination data record. The stored error information can be analyzed upon reproduction of the destination data record so that it can be evaluated, in particular, whether the recorded original data is so seriously defective that a new recording is inevitable. In particular, this is advantageous in video production where it is necessary to quickly evaluate whether a recorded film or video scene is of acceptable quality (if necessary, taking potential retouching into account) or whether it must be repeated and recorded again. | 05-06-2010 |

| 20090268937 | Decoding Watermark Information Items of a Watermarked Audio or Video Signal Using Correlation - Watermark information consists of several data symbols which are embedded continuously in an audio or a video signal using modulation with a pseudo-random sequence if spread spectrum technology is used. At decoder site the watermark information is regained using correlation of the received signal with a candidate pseudo-random sequence. Such correlation can be performed by one-dimensional real-symmetric fast Fourier transform of the two input signal vectors, which each consist of a section of N values of the input signal, to which section N-1 zeroes are attached, by multiplying one of the transformed vectors by the conjugated version of the other transformed vector, followed by inverse RFFT transform of that frequency domain product vector. However, if the level of a spread-spectrum watermark is too low or if too much noise had been added during the transmission of the audio or video signals, the correlation does not show a clear peak, which means that the watermark information bits cannot be recovered. According to the invention, the correlation result is improved by setting to zero in the frequency domain frequency bins of the vector which do not have a positive impact on the correlation peak at location zero, i.e. which frequency bins do not contribute to that peak. Thereby the noise level in the correlation or matched filter output is reduced and the watermark information items can be recovered or decoded correctly from the received watermarked audio or video signal. | 10-29-2009 |
