Abstract
Disclosed herein are a machine architecture implementing a staging automation process, including features such as multiple IR transmitters and composite video inputs for automated high volume quality testing. Diagnostic display outputs from a unit under test are input to OCR and video quality algorithms to validate that the units under test are ready for a functional test process at the next stage.
Claims16
An analytic system for testing a plurality of units under test (UUTs), the analytic system comprising:
- a rack system comprising a plurality of video hardware units, each video hardware unit configured to couple to a corresponding different subset of the UUTs, and to receive video inputs from, and to output infra-red commands to, the corresponding different subset of the UUTs;
- and
- a master control coupled to the plurality of video hardware units;
- wherein each video hardware unit is further configured to
- execute a pre-provisioning phase, a provisioning phase including an initialization and code download stage, and a post-provisioning phase on subsets of the UUTs,
- reconfigure the infra-red commands to the UUTs and the video inputs from the UUTs in response to results of the pre-provisioning phase and the provisioning phase,
- receive via the rack system a UUT test from the master control, and
- return via the rack system a UUT test result to the master control;
- wherein the master control is configured to
- coordinate parallel testing of the pre-provisioning phase, the provisioning phase, and the post-provisioning phase of the UUTs by the video hardware units,
- operate a master RF switch to allocate an RF feed from a cable system headend to the UUTs,
- interoperate with the cable system headend,
- communicate the UUT test, and
- receive the UUT test result via a web server system.

A method of testing a plurality of units under test (UUTs), the method comprising:
- receiving video inputs at a plurality of video hardware units in a rack system from a corresponding different subset of UUTs, each video hardware unit configured to output infra-red commands to the corresponding different subset of the UUTs;
- executing in parallel, at each video hardware unit, a pre-provisioning phase, a provisioning phase including an initialization and code download stage, and a post-provisioning phase on subsets of the UUTs;
- coordinating, with a master control coupled to each video hardware unit, execution of each pre-provisioning phase, each provisioning phase, and each post-provisioning phase;
- reconfiguring the infra-red commands to the UUTs and the video inputs from the UUTs in response to results of the pre-provisioning phase and the provisioning phase;
- receiving, at each video hardware unit, a UUT test from the master control via a web server system;
- and
- returning, by the video hardware unit, a UUT test result to the master control via the web server system.
