An exemplary system includes a High-Definition Multimedia Interface ('HDMI') analyzer and an HDMI router-switch having one or more input ports connected to one or more HDMI source devices and output ports connected to the HDMI analyzer and one or more HDMI sink devices. The HDMI router-switch is configured to establish and disestablish HDMI connections between the HDMI source devices and the HDMI analyzer and HDMI sink devices. The system further includes a control subsystem configured to control the HDMI analyzer, the HDMI router-switch, the HDMI source devices, and the HDMI sink devices, wherein the control subsystem is configured to direct one or more of the HDMI analyzer, the HDMI router-switch, the HDMI source devices, and the HDMI sink devices to perform one or more operations to execute one or more automated HDMI test routines. Corresponding methods and systems are also disclosed.

HDMI device and interoperability testing systems and methods

An exemplary method includes a video content analysis system capturing a first set of video frames representative of a first video content instance and a second set of video frames representative of a second video content instance, applying a morphing heuristic to at least one of the first and second sets of video frames to result in the first and second sets of video frames having a common aspect ratio, a common resolution, and a common container, frame synchronizing, subsequent to the applying of the morphing heuristic, the first and second sets of video frames, and performing a comparative analysis of the frame synchronized first and second sets of video frames. Corresponding methods and systems are also disclosed.

Video content analysis methods and systems

Systems for testing set-top boxes and content distribution networks are provided. In general, systems and methods are described for simulating a set-top box subscriber base, remotely controlling the operations of the set-top boxes of the simulated subscriber base, and analyzing the quality of transmissions received by the set-top boxes. Houses, streets, and towns are simulated using multiple set-top boxes connected to a network. A controller is configured to remotely instruct the set-top boxes to access content from the network and to monitor the operations of the set-top boxes, and an analyzer is configured to monitor the quality of the transmissions received. Methods are also provided for testing set-top boxes and content distribution networks and for testing the quality of transmissions from one source as compared to another source.

System for testing set-top boxes and content distribution networks and associated methods

A test set for evaluating network performance is described, and which may include an output device, a processor, a power supply, a memory unit, and a control terminal. The test set may be configured to receive a user-entered selection of one of a plurality of different bit-error rate profiles and generate a test signal exhibiting the selected bit-error rate profile. The test set may also supply the test signal exhibiting the selected bit-error rate profile to a network under test. In addition, the test set may receive as an input, an output from the network under test. The output may include the test signal exhibiting the selected bit-error rate. The test set may evaluate the received test signal and determine the performance of the network in response to the received test signal exhibiting the bit-error rate. The test set may then output the results of the evaluation.
