Universal Home API

Introduction

The UHAPI Forum standardizes hardware-independent application programming interfaces (APIs) for analog and digital televisions, set top boxes, DVD players and recorders, personal video recorders (PVRs), home servers and other consumer audio/video (A/V) devices.

The forum has released the UHAPI 1.1 specification for Analogue and Digital Television ATSC and Personal Video Recorders (PVR). The latest specifications are available at [1]. The 1.1 version has been donated by the UHAPI Forum to CELF (complying with CELF non-member submission license requirements) and can be downloaded here: attachment:UHAPI1_1.zip .
