Abstract: Systems and methods for providing timing information from a R-MACHPHY device to a video core while the R-MACPHY device receives video data from the video core while operating in asynchronous mode. In some embodiments, the R-MACPHY device may alternately and selectively configure its mode of operation to alternate between synchronous mode and asynchronous mode, and provide the timing information to the video core when it switches to asynchronous mode.

Abstract: A method and system provide the ability to deliver media content. A packager receives an original encrypted transport stream, and segments the stream into multiple fixed-duration transport stream files (chunks). The packager further generates a manifest file that describes the chunks and is consistent with a hypertext transfer protocol (HTTP) live streaming (HLS) protocol. The manifest file and chunks are delivered to a content delivery network (CDN). An enhanced HLS client is embed in an integrated receiver decoder (IRD). The enhanced HLS client retrieves the manifest file and the chunks from the CDN, and reconstructs the original encrypted transport stream for use by a service provider network.

Abstract: A method for transcoding a digital video stream that includes transcoding using a transcoder a video stream that includes presentation time stamps for the video stream together with an audio stream that includes presentation time stamps for the audio stream in a manner that modifies the presentation time stamps for the video stream in a manner such that a plurality of first values for presentation time stamps for a first set of video frames of the video stream are modified to a plurality of second values for presentation time stamps for the second set of video frames. The audio stream includes embedded first values for presentation time stamps in a first location. The method includes determining an offset of the second values of the second set of presentation time stamps of the transcoded video stream based upon the first values of the set of presentation time stamps embedded in the audio stream from the transcoder.

Abstract: Methods and systems of preventing skipping of advertising content are shown and disclosed. In one embodiment, the method includes providing one or more multimedia streams to an Internet protocol (TP) client and receiving a HTTP range request or time seek associated with the one or more multimedia streams from the IP client. The method additionally includes determining proximity of an upcoming targeted advertising (TAD) boundary in the one or more multimedia streams when the HTTP range request or time seek is received and/or determining whether the HTTP range request or time seek is for multimedia content that is after an upcoming targeted advertising (TAD) region. The method further includes responding to the HTTP range request or time seek based on the above determination.

Abstract: A method for inter-coding video is provided in which transmission bandwidth requirements associated with second motion vectors for bi-directional temporal prediction is reduced. In the method motion vector information for only one of the two motion vectors for bi-directional temporal prediction can be transmitted together with information on how to derive or construct the second motion vector. Thus, rather than sending express information regarding two motion vectors, express information related to only one motion vector along with information related to reconstruction/derivation of the second motion vector is transmitted, thus reducing bandwidth requirements and increasing coding efficiency.

Abstract: Particular embodiments may remove a condition check in the semantics for checking a high-precision data flag. This simplifies the semantics used in the encoding and decoding process. In this case, even if the high-precision data flag is not set, the value of the weighted prediction syntax element is set by the BitDepth variable. However, even if the BitDepth is not considered high-precision data, such as 8 bits, the range for the weighted prediction syntax element is still the same as the fixed value. For example, the syntax elements luma_offset_l0[i], luma_offset_l1[i], delta_chroma_offset_l0[i][j], and delta_chroma_offset_l1[i][j] use the variable BitDepth as described above whether the flag extended_precision_processing_flag is enabled and not enabled to indicate whether the bit depth is above a threshold.

Abstract: A method for determining a resampling filter for resampling a video signal used in scalable video coding includes estimating a set of row filters based on a video signal. The video signal has a base resolution that is resampled to provide an output signal that enables more efficient coding of the video signal with an enhanced resolution higher than a base resolution. The set of row filters is applied to the video signal to generate a first output signal having rows that are interpolated to the enhanced resolution. A set of column filters is estimated based on the first output signal for resampling the columns in the video signal. The set of column filters is applied to the first output signal to generate a second output signal having columns as well as rows that are interpolated to the enhanced resolution.

Abstract: During operation, the computer may obtain an access acceptance message, where the access acceptance message indicates that the electronic device has been authenticated and allowed to securely access a network, and where the authentication is based at least in part on a passphrase associated with a user of an electronic device. For example, the computer may receive the acceptance message from the computer network device or a second computer (such as a controller). Alternatively, the computer may obtain the access acceptance message while performing the authentication. Then, the computer may automatically provide a second passphrase addressed to a computer network device and the electronic device, where the second passphrase replaces the passphrase during a current session of the electronic device in the network. Moreover, when the current session ends, the computer may automatically revert to the passphrase for subsequent authentication of the user.
