I. Introduction
Such network home appliances as televisions, HDD/DVD recorders, and audio devices, can be interconnected by the Digital Living Network Alliance (DLNA) [1]. Network home appliances based on the DLNA guidelines offer data and content transferability to other DLNA home appliances through remote controls called Digital Media Controllers (DMC). An example is shown in Fig. 1. Using a DMC, a user can transfer multiple contents stored on multiple recorders that are connected to the home network to a particular television display that is also connected to the home network. The DMC displays a list of available television displays or a Digital Media Renderer (DMR) and the transferable contents stored on the networked recorders or the Digital Media Servers (DMS). Thus, users can play the content on any DMR by operating the DMC.
