DLNA-compliant device, DLNA connection setting method, and program
First Claim
1. A DLNA-compliant device, comprising:
- a device discovery section configured to discover another network-connected DLNA-compliant device;
a device decision section configured to decide whether said another DLNA-compliant device discovered by said device discovery section is a DLNA-compliant device directly connected by a transmission path of HDMI based on a bias potential of a reserved line of an HDMI cable connected to said DLNA-compliant device; and
a connection setting section configured to execute connection setting of DLNA with said another DLNA-compliant device decided to be said directly connected DLNA-compliant device by said device decision section,wherein said device decision section enquires the another DLNA-compliant device discovered by said device discovery section for HDMI compliance via a CEC line of the HDMI cable.

Abstract
[Problem]
To enhance the ease of use of a network by a DLNA-compliant device.
[Solving Means]
A television receiver 250 discovers another DLNA-compliant device connected to a network (S3). Then the television receiver 250 determines an IP address of eHDMI connection (S4) and, in the case of a device directly connected by HDMI, connection setting of a DLNA with that device is automatically executed (S5 through S8). The television receiver 250 may present each connection setting state to a user on a user interface screen, thereby making the user execute checking. In configuring an AV system, the user may execute direct connection by HDMI to enhance the ease of use of an AV system 200 without having to execute the connection setting of DLNA.
