Multimedia player displaying operation panel depending on contents

A digital content reproducing apparatus, comprising:

• a network connector configured to receive a digital content via a network,
• wherein the digital content is associated with attribute information including at least first attribute information that associates an appreciation term with the digital content and second attribute information corresponding to viewing history of the digital content;
• a demultiplexer configured to extract video signal from the digital content received by the network connector;
• a decoder configured to decode the video signal of the digital content extracted by the demultiplexer;
• a user operation receiver configured to receive a user operation for the digital content reproducing apparatus by a remote controller;
• a renderer configured to generate image data in which the decoded digital content and either a linear operation panel allowing user-instruction regarding linear reproduction functions of the decoded digital content or an interactive operation panel allowing user-instruction of interactive functions to an outside of the digital content reproducing apparatus are superimposed;
• a display configured to display the image data;
• and
• a controller configured to control alternative display of the linear operation panel and the interactive operation panel,
• wherein the linear operation panel and the interactive operation panel are distinct panels from each other, which are not generated by disabling of buttons and which are displayed with the same decoded digital content,
• wherein only one of the linear operation panel and the interactive operation panel is displayed exclusively at any given time, together with the decoded digital content,
• wherein the decoded digital content together with either the linear operation panel or the interactive operation panel, are displayed concurrently in one screen,
• wherein the digital content is decoded and displayed on the display when the appreciation term in the first attribute information has not lapsed,
• wherein the viewing history in the second attribute information provides an indication corresponding to an amount of the digital content that has been viewed, and
• wherein when the user operation receiver receives a user operation to request video on demand services, the network connector requests a digital content via the network.
