1. A method of receiving an adaptive broadcast signal, comprising the steps of:
- linking an IP network;
connecting to a service provider via the linked IP network, wherein an authentication process is performed, available services based on capability of a receiver are displayed;
sending supported encoding information of the receiver to the service provider when performing service discovery;
receiving service selection data including a list about an available media service for the receiver from the service provider, the service selection data being customized by the service provider based on the sent supported encoding information;
displaying the list which specifies at least one content of the available media service and at least one supported encoding format which is related to the at least one content;
sending selected content information indicating a content and a supported encoding format of the content when a user selects the content and the supported encoding format of the content from the displayed list;
receiving the content of an encoding format suitable for the receiver from the service provider; and
wherein if media codec information for contents provided by the service provider is not matched to the supported encoding information of the receiver, receiving a downloadable codec list provided by the service provider, comprising;
selecting at least one codec from the received downloadable codec list; and
downloading the selected at least one codec from the service provider,wherein the encoding information includes audio encoding information specifying supported audio encoding properties and video encoding information specifying supported video encoding properties, andwherein in the step of selecting the at least one service from the list about an available media service in the receiver, a user codec selection signal is inputted via an OSD.

6. An adaptive IPTV receiver comprising:
-
a network interface unit transceiving a broadcast stream capsulated into an IP packet by connecting the IPTV receiver to a service provider via a network; a decoder decoding the received broadcast stream; a display unit outputting the broadcast stream decoded by the decoder, wherein an authentication process is performed, the display unit is configured to display available services based on capability of the IPTV receiver; and a control unit controlling the network interface to send supported encoding information of the IPTV receiver to a service provider when performing service discovery, to receive service selection data including a list about an available media service for the IPTV receiver which is customized based on the sent supported encoding information of the IPTV receiver, to send selected content information indicating a content and a supported encoding format of the content when a user selects the content and the supported encoding format of the content and to receive the content of an encoding format suitable for the receiver from the service provider, wherein in the step of selecting the at least one service from the list about an available media service in the receiver, a user codec selection signal is inputted via an OSD; wherein the encoding information includes audio encoding information specifying supported audio encoding properties and video encoding information specifying supported video encoding properties, wherein the control unit further controls the display unit to display the list which specifies at least one content of the available media service and at least one supported encoding format which is related to the at least one content, and wherein if media codec information for contents provided by the service provider is not matched to the supported encoding information of the receiver, receiving a downloadable codec list provided by the service provider, comprising; selecting at least one codec from the received downloadable codec list; and downloading the selected at least one codec from the service provider. - View Dependent Claims (7, 8)
