Abstract
A variety of device interfaces may be connected to a test platform in a fast and efficient manner using multi-pin cables and connectors to support high-volume processing of devices to be tested. The multi-pin cables and connectors may aggregate a plurality of specific device interfaces into a single cable that can be connected via a connector to a test shelf and via a connector to a test platform, reducing the time to setup for device testing and facilitating high-volume processing of devices to be tested.
Claims5
A method, comprising:
- transmitting a low sharpness video stream to a CPE device;
- receiving a processed video stream generated by the CPE device while processing the low sharpness video stream;
- evaluating the processed video stream using an evaluation algorithm that evaluates frames of the processed video stream to determine a blockiness metric by tracking a number of sudden or sharp changes in the processed video stream;
- and
- determining a poor video processing performance by the CPE device when the calculated blockiness metric is outside of a predetermined threshold.
