    Abstract: A method that incorporates teachings of the subject disclosure may include, for example, receiving, by a system comprising a processor, first media content from a service provider network over a high resolution channel at a first resolution, determining whether a first resolution exceeds a resolution threshold for viewing the first media content, transmitting a notification to the service provider network that the first resolution exceeds the resolution threshold, receiving the first media content from the service provider network over the high resolution channel at a second resolution according to the notification, wherein a difference between the first resolution and the second resolution provides unused bandwidth on the high resolution channel, and receiving second media content from the service provider network over the unused bandwidth of the high resolution channel. Other embodiments are disclosed.

    Abstract: A method includes receiving, by a device, a first image of a scene and a second image of at least a portion of the scene. The method includes identifying a first plurality of features from the first image and comparing the first plurality of features to a second plurality of features from the second image to identify a common feature. The method includes determining a particular subset of pixels that corresponds to the common feature, the particular subset of pixels corresponding to a first subset of pixels of the first image and a second subset of pixels of the second image. The method also includes generating a first image quality estimate of the first image based on a comparison of a first degree of variation within the first subset of pixels and a second degree of variation within the second subset of pixels.

    Abstract: A method includes identifying an area in an image that is associated with strong directional energy. The method further includes determining a first estimate of signal energy for the area and a second estimate of aliasing energy for the area. The method further includes estimating a severity of an aliasing error of the image based on the first estimate and the second estimate.

    Abstract: Example methods and apparatus to detect transport faults in media presentation systems are disclosed. An example method comprises decoding a media stream to form audio data and pixel data, computing a first value representative of the media stream using pixel data associated with a first set of the video frames, computing a second value representative of the media stream using pixel data associated with a second set of the video frames, computing a third value representative of first speech in a first segment of the audio data, computing a fourth value representative of second speech in a second segment of the audio data, determining a fifth value representative of a likelihood that a transport failure has affected the media stream, the fifth value determined using the first, second, third and fourth values, and comparing the fifth value to a threshold to determine whether to generate a transport failure alert.
