SOURCE-CONSISTENT TECHNIQUES FOR PREDICTING ABSOLUTE PERCEPTUAL VIDEO QUALITY

In various embodiments, a perceptual quality application computes an absolute quality score for encoded video content. In operation, the perceptual quality application selects a model based on the spatial resolution of the video content from which the encoded video content is derived. The model associates a set of objective values for a set of objective quality metrics with an absolute quality score. The perceptual quality application determines a set of target objective values for the objective quality metrics based on the encoded video content. Subsequently, the perceptual quality application computes the absolute quality score for the encoded video content based on the selected model and the set of target objective values. Because the absolute quality score is independent of the quality of the video content, the absolute quality score accurately reflects the perceived quality of a wide range of encoded video content when decoded and viewed.

Based on the coordination index, the coordination server generates a signal to indicate a broadcast status of the broadcast event. Upon the signal being read by the online content server, the online content server transmits the online content to the computing device in accordance with one or more rules for interpreting the signal.

SYSTEM AND METHOD FOR SUPPORTING MULTIPLE IDENTITIES FOR A SECURE IDENTITY DEVICE

A multiple-identity secure device (MISD) persistently stores a single identification code (a "seed identity"). The seed identity need not be a network address, and may be stored in an integral memory of the device, or on an interchangeable card received in a physical interface of the MISD. The MISD is provided with a transformation engine, in hardware or software form, that is subsequently used to generate one or more unique identities (e.g., network addresses) from the stored seed identity using predefined logic. The generated identities may be dynamically generated, e.g., in real-time as needed after deployment of a device into possession of a subscriber/customer/user, etc., or may be securely stored in the MISD for subsequent retrieval. The transformation engine may generate a unique identity in accordance with an addressing scheme identified as a default setting, a global/network setting, or as determined from a received data transmission.

SWITCHING CONFIGURATION FOR SPLITTING A DIGITAL LINE INTERLACING TELEVISION SIGNAL INTO SIGNAL COMPONENTS

Source-consistent techniques for predicting absolute perceptual video quality

In various embodiments, a perceptual quality application computes an absolute quality score for encoded video content. In operation, the perceptual quality application selects a model based on the spatial resolution of the video content from 5 which the encoded video content is derived. The model associates a set of objective values for a set of objective quality metrics with an absolute quality score. The perceptual quality application determines a set of target objective values for the objective quality metrics based on the encoded video content. Subsequently, the perceptual quality application computes the absolute quality score for the encoded 10 video content based on the selected model and the set of target objective values. Because the absolute quality score is independent of the quality of the video content, the absolute quality score accurately reflects the perceived quality of a wide range of encoded video content when decoded and viewed.
