  • Publication number: 20170347139
    Abstract: Monitoring quality of experience (QoE) using a no-reference (NR) method. An uncompressed audio/video (AV) stream is received from output of a device under test (DUT), where the uncompressed AV stream includes content that is known to be devoid of a set of one or more AV artifacts. At least one of the set of AV artifacts is automatically tested for its existence using a no-reference method that does not use a comparison to an input reference AV stream. Upon determining that there is an AV event representing one of the set of AV artifacts based on the automatic testing, a video clip that includes the AV event is automatically generated. The automatically generated video clip is stored.

  • Patent number: 9740952
    Abstract: Exemplary methods and processing systems for determining whether an audio video (AV) source is performing closed captioning (CC) rendering properly, are described. An AV stream including one or more AV frames is received from the AV source; for each frame from the AV stream the following operations are performed: detecting a CC image in the frame; cropping the CC image from the frame; and outputting the CC image and metadata associated with the frame. A caption file is generated based on the AV stream, where the caption file includes captioning information for the AV stream. The CC image and metadata output for a frame from the AV stream are compared with CC information within the caption file related to that frame to determine whether the AV source is performing CC rendering properly.

  • Patent number: 8337345
    Abstract: The high-performance sliding rack ratchet tensioner is inexpensively manufactured. A rack having rack teeth is slidingly received in a rack slot on the side of the piston. The rack slot is preferably open-ended on the end facing the tensioner arm. The rack and piston are both received in a piston bore in the tensioner body. The rack length is preferably shorter than the rack slot length to provide backlash. A pawl mounted in a pawl bore perpendicular to the rack bore engages the rack. The open-ended rack slot allows the rack to be inserted after the piston during assembly. The rack and pawl preferably have shark fin-shaped teeth. The pawl preferably has dummy teeth to ensure that the load is shared by the center teeth.
