BACKGROUND

1. Field

One embodiment of the invention relates to a television receiving apparatus, an information processing apparatus, and a display method.

2. Description of the Related Art

In recent years with the progress of digitization of television sets, vigorous discussions have been conducted on television sets accessible to networks, how the services of the networks should be provided through the television platform. Television sets connectable to the networks are being commercialized.

With the development of such a network television sets, Web services, which have traditionally been typically used through Personal Computers (PCs) and cellular phones, are considered as being used through the television sets. In view of the characteristics of the television sets, their nature would be to receive broadcast wave. In view of the nature of the television sets and the usage of the Web services, an aspect of providing services to suit the preference of the users who watch particular television programs, is very important.

Of such services, a communications service (information exchange service) using real time text data, which is so-called messenger or chat, is attractive.

For example, Japanese Patent Application Publication (KOKAI) No. 2001-148841 discloses a technology for forming a television community in which television audience are able to communicate with each other interactively and freely, by forming a community which may be composed of a plurality of terminals of audience synchronized with channel information.

However, inputting information into a television set with a connected keyboard and mouse as in a PC is not all that realistic because it is assumed that the television set is used as a passive device in many cases. Therefore, it is necessary to watch airwaves on the television while conducting an operation for a chat on separate information processing apparatuses such as PCs and cellular phones, which are suitable for inputting information in order to realize, for example, the service of conducting the chat on the community formed by the television audience.

However, under such a system constitution, the users concern tends to be turned on the separate information processing apparatuses rather than on the television. As a result, it is difficult to realize conducting the chat service while watching the television, and therefore the system does not satisfy the needs of all users.
