Control of multiple AV-devices by a single master controller using infrared transmitted commands and bus transmitted commands
First Claim
1. An audio/video platform (AVP) for a video signal processing system, comprising:
- a digital communications port for transferring control and data signals between the AVP and at least a first video device;
at least one analog video communications port for transferring video signals between a second video device and the AVP;
an infrared transmitter for transmitting infrared commands; and
a control processor coupled to the digital video communications port and to the infrared transmitter for sending control commands to the first video device via the digital communications port and for sending control commands to the second video device via the infrared transmitter.

Abstract
An audio-video platform (AVP) performs as a master controller to interconnect other AV devices and provide unified control of all the AV devices connected to it. The AVP receives all control signals from users and controls slave mode AV devices via an IEEE-1394 bus and master mode AV STBs by using an infrared (IR) blaster, having a command set equivalent to the infrared remote control of the master-mode AV device. The AVP also controls legacy devices via the IR blaster. The AVP has on screen display (OSD) and provides unified graphic user interface (GUI) for connected AV devices. The AVP can transfer compressed AV signals for processing and display in one common format, making it possible to display video from all AV devices.

8. A method for controlling a plurality of video devices from an audio/video platform, wherein a first group of the plurality of video devices include respective digital communications ports and are configured as slave mode devices and a second group of the plurality of video devices include respective digital communications ports and are configured as master mode devices, at least the second group of video devices including an infrared receiver which responds to commands transmitted by an infrared remote control device, the method comprising the steps of:
-
transmitting digital commands to the first group of the plurality of video devices using the digital communications port; and
transmitting infrared commands to the second group of the plurality of video devices. - View Dependent Claims (9, 10, 11, 12)
