Title
(EN) TWO WAY CONTROL OF A SET TOP BOX USING OPTICAL CHARACTER RECOGNITION
(FR) COMMANDE BIDIRECTIONNELLE D'UN BOÎTIER DÉCODEUR AU MOYEN D'UNE RECONNAISSANCE OPTIQUE DE CARACTÈRES
Abstract
(EN) 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.
(FR) Des caractéristiques de divers modes de réalisation de l'invention sont utilisées pour commander le fonctionnement d'un second dispositif électronique à partir d'un premier dispositif électronique au moyen de procédés de commande indirecte et d'une reconnaissance optique de caractères. Dans certains modes de réalisation, la communication entre un boîtier décodeur primaire et un boîtier décodeur supplémentaire est configurée de manière à éviter le recours à une ou plusieurs API spécifiques de fournisseur. Par exemple, un aspect de la présente invention concerne un procédé d'identification d'instructions qui peuvent être utilisées pour commander une ou plusieurs fonctions d'un boîtier décodeur principal (par exemple, des fonctions de magnétoscope numérique (DVR) ou de vidéo à la demande (VOD)) par un boîtier décodeur supplémentaire envoyant des instructions au boîtier décodeur principal par l'intermédiaire d'un émetteur sans fil (par exemple, infrarouge (IR)), puis utilisant une reconnaissance optique de caractères pour identifier les résultats de ces instructions affichés sur un écran de télévision (TV) primaire ou sur un écran secondaire.
