Abstract: Methods, systems, and devices for improving security of media streams are disclosed. The system can receive a decoded media stream from a media decoding pipeline that receives and decodes an encoded media stream. The system can identify, based on the decoded media stream, a set of features to generate, and generate the set of features using the decoded media stream. Such features may include luma histograms, pixel intensity data, motion vectors, edge detection, audio gain, tonal information, pitch information, among other types of features. The system can provide the set of features to a processor executing a machine-learning model, wherein the processor executing the machine-learning model is prevented from accessing the decoded media stream by the device.

Abstract: Techniques described herein are directed to the inline switching of video and/or audio codecs for video and/or audio data. A first device encodes data that includes portion(s) that are encoded using a first codec and portion(s) that are encoded using a second codec. The encoder may further encode supplemental information in the data. The supplemental information is used by the decoder to determine a transition between the first and second portion(s). The decoder can thus anticipate the transition and properly switch the codec used to decode the data in real-time. Techniques described herein are also directed to the splicing of locally-stored content into content received from a remotely-located source. For example, targeted advertisements that are stored locally may be played back during commercial breaks of live content. The locally-stored targeted advertisements may replace the commercials provided via the remotely-located source.

Abstract: Various systems and methods are provided for transmission of related data components across independent streams. In one embodiment, among others, a transmitting device may separate transmission data into related data components and transmit each related data component in an associated transport stream. Each related data component includes a synchronization tag associated with synchronization of the related data component within the transmission data. In another embodiment, a receiving device may receive related data components transmitted in separate transport streams and decode the related data components based at least in part upon a synchronization tag included in each related data component.

Abstract: Disclosed are various embodiments for transcoding a video stream to facilitate accurate display. An uncompressed video stream comprising a sequence of video frames is obtained. An encoded reverse order video stream is generated from the uncompressed video stream in one embodiment. In another embodiment, the uncompressed video stream includes multiple views, and a compressed video stream is generated from the uncompressed video stream. The compressed video stream excludes one or more of the views.

Abstract: An example video coding system may include a processor and memory. The processor may determine sets of parameters for slices that correspond to a picture of a video sequence, and determine, and store in overhead information, the set of parameters that has the highest commonality. The processor may determine for each slice whether the set of parameters determined for the slice is equivalent to the set of parameters stored in overhead information. If the set of parameters for the slice is equivalent to the set of parameters stored in overhead information, the processor may store an indication in a slice header of the slice that indicates that the set of parameters stored in overhead information applies to the slice, otherwise the processor may store in the slice header of the slice the determined set of parameters for the slice. The processor may transmit the overhead information and the slices.

Abstract: A 3-dimensional (3D) video transmitter may be operable to encode a 3D video to generate a scalable video coding (SVC) base layer and a SVC enhancement layer. A first view such as a first high-resolution view and a second view such as a second high-resolution view of the 3D video in the SVC enhancement layer may be separate frames. A first half-resolution view and a second half-resolution view of the 3D video in the SVC base layer may be packed in a single frame. The first half-resolution view in the SVC base layer may be a base-layer reference for the first high-resolution view in the SVC enhancement layer for inter-layer prediction of spatial scalable coding. The first high-resolution view in the SVC enhancement layer may be an intra-layer reference for the second high-resolution view in the SVC enhancement layer for intra-layer prediction of temporal scalable coding.

Abstract: Aspects of fast channel change of programs are presented. Initial pictures of a program may be decoded earlier and displayed longer than what is indicated by corresponding clock references. Additional pictures of the program may be decoded and displayed at time indicated by the clock references. Within the time period of the initial pictures, decoding timing advances of initial pictures may be reduced and corresponding picture displaying rates may converge to an intended constant frame rate used for additional pictures displaying. Pictures may be decoded and displayed when the corresponding data are available in a coded data buffer (CDB) and a decoded picture buffer (DPB), respectively. Depending on the implementation, the respective previous picture may be displayed when a decoded picture is available in the DPB.

Abstract: Different data communication architectures deliver a wide variety of content, including audio and video content, to consumers. The architectures employ channel bonding to deliver more bandwidth than any single communication channel can carry. In some implementations, the communication architectures distribute video programming in the form of MPEG2 TS packets, flagged by marker packets, in a round-robin manner across the communication channels. Channel bonding synchronization information may be present in packets defined above the data-link layer or added to fields within data-link layer frames.

Abstract: Disclosed are various embodiments of three-dimensional (3D) video coding using scalable video coding (SVC) spatial scalability. In one embodiment, 3D video is encoded to generate a SVC base layer that includes a left first-resolution view and a right first-resolution view packed in a first frame. 3D video is encoded to generate a SVC enhancement layer that includes a left second-resolution view and a right second-resolution view packed in a second frame. The left second-resolution view and the right second-resolution view may have a higher spatial resolution than the left first-resolution view and the right first-resolution view.
