  • Publication number: 20170134738
    Abstract: In some aspects, the disclosure is directed to methods and systems for encoding and sharing media clips via a social networking provider responsive to a user interaction via a single “like” or “share” button. Media may be constantly buffered as the user watches the program, such that the user need not initiate recording, enabling the user to quickly share amusing or media clips as they happen live. The device may decode, scale or subsample, and compress or re-encode the media to take up less space in a buffer of the device and/or to comply with copyright fair use requirements. Responsive to the user interaction or “share” command, the device may transfer the contents of the buffer to a social media service along with instructions to generate a post to the social network identifying the user, media, and/or buffer contents.

  • Publication number: 20170117058
    Abstract: A non-volatile memory cell, having an antifuse for storing data, is disclosed for use in a non-volatile data storage device. The non-volatile memory cell includes multiple redundant signal pathways to provide redundant access to the antifuse. During operation, the non-volatile memory cell can access the antifuse using a first signal pathway from among the multiple redundant signal pathways. However, when the first signal pathway is inoperable, the non-volatile memory cell is able to access the antifuse using a second signal pathway from among the multiple redundant signal pathways. The non-volatile memory cell is fabricated using a continuous region of one or more diffusion layers to allow efficient connection to other non-volatile memory cells to form an array of memory cells for the non-volatile data storage device.

  • Publication number: 20170118489
    Abstract: Compounding reproduction errors in the luminance of a pixel encoded by a non-constant luminance video encoder is High Dynamic Range (HDR) video content, which is starting to become more widely supported by commercially available display devices. HDR video content contains information that covers a wider luminance range than traditional, non-HDR video content known as Low Dynamic Range (LDR) video content. The present disclosure is directed to an apparatus and method for reducing errors in reproduced luminance of HDR video content (and other types of video content) at a video encoder and/or video decoder due to non-constant luminance video encoding.

  • Patent number: 9622247
    Abstract: Preamble and header bit allocation for power savings within multiple user, multiple access, and/or MIMO wireless communications. Within a multi-user packet, information (e.g., partial address information) related to a recipient group of wireless communication devices (e.g., as few as one wireless communication device or any subset of a number of wireless communication devices, sometimes including all of the wireless communication devices) is emplaced within a PHY (e.g., physical layer) header of such a multi-user packet to be communicated within a multi-user (MU) environment. Such recipient indicating information can be encoded with relatively higher robustness (e.g., lower coding rates, lower ordered modulation, cyclic redundancy check (CRC), etc.) that remaining portions of the multi-user packet. Various portions of the remainder of the multi-user packet may respectively correspond to different wireless communication devices (e.g.

  • Patent number: 9603025
    Abstract: A method for synchronizing channels on unlicensed bands is described. The method includes determining whether a SCC channel has started to be used by a first network. The SCC channel is a CA channel shared with at least one other network. In response to determining that the SCC channel has been started to be used by the first network, the UE determines an off duration describing a period since a previous SCC channel ON period. A given channel ON period is a continuous period of use of the given channel by the first network, The method also includes, in response to determining that the off duration is less than a minimum threshold duration, performing fine synchronization based on CRS tracking on the SCC channel using course synchronization parameters of the previous SCC channel ON period. Apparatus and computer readable media are also described.
