Middleware для D-Link DIB-120

Пример middleware для цифровой ТВ-приставки D-Link DIB-120.

В скрипте реализована только базовая часть функционала, позволяющая достаточно комфортно просматривать цифровое телевидение, на момент написания большего и не требовалось. Вообще, полный перечень поддерживаемых команд можно найти в интернете.

Подробнее об использовании можно ознакомиться в статье IPTV Своими руками: Первый опыт

DIB120_API.js
Функция processItem обрабатывает нажатие кнопок пульта. В данной реализации скрипта используются только цифровые кнопки и кнопки страничного переключения каналов (для смены каналов). Так же кнопка Play и Stop для запуска и остановки потока.
Для определения идентификатора кнопки, я использовал функцию alert - при нажатии на кнопку пульта на экране отобразиться ее идентификатор.
