    Abstract: Methods and systems for achieving a high frame rate video with compatibility for existing receivers without depending bitstream encoding are provided herein. For example, an apparatus comprises: a memory; and one or more processors configured to execute instructions stored in the memory. The instructions comprise: receiving a first bitstream having a first packet identifier (“PID”) and a second bitstream having a second PID; decoding the first bitstream and the second bitstream; and interleaving the decoded first bitstream and the decoded second bitstream to form a high frame rate video signal, wherein the high frame rate video signal has a frame rate equal to the sum of the frame rate of the decoded first bitstream and the decoded second bitstream.

    Abstract: In one embodiment, a receiver for an accelerated channel change is provided. The receiver receives a first version of a video stream for a first channel and causes display of video for the first version of the video stream for the channel. A second version of a video stream is received upon a channel change to a second channel, the second version including non-discardable pictures from the first version of the video stream. The receiver displays video for the second version of the video stream for the second channel. When a transition point is reached in the first version of the video stream for the second channel, a first version of a video stream for the second channel can be displayed.

    Abstract: Systems and methods for training voice activation control of electronic equipment are disclosed. One example method includes receiving a selection corresponding to at least one command used to control the electronic equipment. The method further includes instructing a user to speak, and responsive to the instruction, receiving a digitized speech stream. The method further includes segmenting the speech stream into speech segments, storing at least one of the speech segments as an entry in a dictionary, and associating the dictionary entry with the selected command.

    Abstract: Embodiments of systems and methods for signaling chroma information for a picture in a compressed video stream are provided. One system embodiment, among others, comprises a memory with logic, and a processor configured with the logic to provide a compressed video stream that includes a picture having chroma samples and luma samples, and provide in the compressed video stream a flag for signaling information corresponding to the location of the chroma samples in relation to the luma samples in the picture, wherein a first defined flag value indicates default locations of the chroma samples in relation to the luma samples in the picture, wherein a second defined flag value indicates a presence in the compressed video stream of auxiliary chroma information corresponding to relative locations of the chroma samples to the luma samples in the picture, and wherein the number of chroma samples in the picture implied by the first defined flag value is equal to the number of chroma samples in the picture implied by the second defined flag value. Other embodiments for signaling chroma information for a picture in a compressed video stream are included herein.
