  • Publication number: 20140379747
    Abstract: Systems, methods, and computer-readable storage media are provided for permitting users to search the content of a plurality of apps from a single search query input location. A user inputs a search query and a plurality of apps and/or the content thereof is searched to determine relevancy to the input query. If an app having relevant app content is identified, it may be determined if the app is associated with the querying user. If it is determined that the app is associated with the querying user, the information determined relevant to the input query may be presented to the user. If, it is determined that the app is not associated with the user, the user may be presented with the identity of the app and/or be directed to a location (e.g., an app store) where the user can become associated with the identified app and obtain the desired information.

  • Patent number: 8498330
    Abstract: Method and apparatus for providing a fast and accurate video coding process are disclosed. After checking the coding history of certain coded video frame units of a video, the order of the inter prediction and the intra prediction is adaptively exchanged for each coding video frame unit of an inter frame. Furthermore, the computations for coding modes in the latter part of the computation order are selectively skipped so as to speed up the coding process without degrading the video quality.

  • Publication number: 20130190195
    Abstract: Particles that generate electromagnetic spectra upon appropriate illumination and in which the spectra can be converted to codes that reflect differences in the spectra are functionalized with a plurality of identical primer pairs on which bridge amplification can be performed. Using these particles, nucleic acids in a biological sample are amplified and exposed to a label that sends a signal only when bound to double-stranded DNA. The code for each particle is correlated with the primer pairs, and the captured nucleic acids are thus detected and identified. The procedure is useful for multiplex DNA or RNA detection as well as counting of target DNA and RNA molecules in the sample.

  • Patent number: 8451896
    Abstract: The invention relates to adjusting the quantization parameter in digital video coding. A shift value (QP Shift) is used to adjust the quantization parameter. The shift value is determined in a determining step 101. The video nature is determined and compared with a threshold in a comparing step 102 to adjust the shift value adaptively according to the frame type in an adjusting step 103. The shift value shifts the quantization parameter in a shifting step 104.
