20210258639 | SYSTEMS AND METHODS FOR OPERATING A SET TOP BOX - Features of various implementations are used to control operation of a second electronic device from a first electronic device using indirect control methods and optical character recognition. In some implementations, communication between a primary set-top box and a supplemental set-top box is configured in order to avoid the need for one or more provider-specific APIs. For example, one aspect of the disclosure is a method of identifying commands that can be used to control one or more features of a primary set-top box (e.g., DVR or VOD features) by a supplemental set-top box issuing commands to the primary set-top box via a wireless (e.g., IR) transmitter, and then using optical character recognition to identify the outcomes of those commands as displayed on a primary TV display or secondary display. | 2021-08-19 |
