A first index corresponding to a first conversation operation and a second index corresponding to a second conversation operation are selectably displayed on a screen of a video output device. When a communicator receives a conversation request from another device, a controller determines whether the first index or the second index is selected on the screen or whether an operating member is operated. If the first index is selected, the controller performs the first conversation operation. If the second index is selected, the controller performs the second conversation operation. If the operating member is operated, the controller performs the second conversation operation.

Communication device, communication method therefor, and communication program therefor

According to the present invention, when video resolution is changed, the TV receiver selects resolution having a priority to the graphics resolution requested by the application depending on the application types, or the TV receiver selects graphics resolution appropriate for video format resolution, thereby the TV receiver enables the clear display of graphics without causing any distortion.

In the case where plural applications are executed at the same time, if each application instructs for different trick play to the same content, a difference is caused between an ideal reproduction state expected by each application and an actual reproduction state. The present invention makes it possible to keep the reproduction state unchanged as long as normal reproduction or trick play is not accepted, by including a moving picture trick play reproduction management unit which determines, in response to an instruction for one of normal reproduction and trick play, whether or not to accept, according to a rule, the instruction, and retains details specified by the instruction in the case of accepting the instruction, and a moving picture reproduction processing unit which reproduces a moving picture based on the details retained by the moving picture trick play management unit.

Recording and reproduction apparatus and recording and reproduction method

A broadcast system BS includes a broadcast apparatusand a reception apparatus. The broadcast apparatusfirst receives and stores therein a proxy request PR including at least an identifier assigned to the reception apparatusand a command to be transmitted to the reception apparatus. Moreover, the broadcast apparatusextracts the set of the identifier of the reception apparatusand the command for the reception apparatusfrom the proxy request PR stored therein, and assembles a command packet from the set of the identifier and the command. Then, the broadcast apparatusgenerates a stream in which the assembled command packet is multiplexed, and sends it out to a broadcast channel. The reception apparatusseparates the command packet from the stream sent out to the broadcast channel, and restores the set of the identifier and the command of the reception apparatus. Then, the reception apparatusdetermines whether or not the disassembled command is destined for the present reception apparatus based on the pre-stored identifier of the present reception apparatus and the disassembled identifier of the reception apparatus. If so, the reception apparatusstores therein the command destined for the present reception apparatus. The reception apparatusexecutes the command, which has bee stored as described above.

The embedded program comprises a part of the function of the Java program. The embedded program executes the part of the function during the start-up processing period of Java program. Thus, the start-up time appears to be shortened. Further, the present invention provides the information regarding the action state of the embedded program to the Java program, thereby enabling a consistent execution of the Java program on completion of the Java program start-up process.

Program executing apparatus

A broadcast reception apparatus is provided with a reception unit for receiving broadcast data as a transport stream. The transport stream includes video data and a plurality of navigation information sequences. Each navigation information sequence includes navigation information which includes graphics data to be combined with the video data for display. A TS (Transport Stream) decoder unit extracts the video data and navigation information from the transport stream. A reception control unit controls the TS decoder unit so that the TS decoder unit extracts navigation information from a navigation information sequence which is suitable for the the broadcast reception apparatus. A navigation information storage unit stores the navigation information extracted by the TS decoder unit. A reproduction control unit combines graphics data included in the navigation information stored in the navigation information storage unit with the video data extracted by the TS decoder unit and displays a composite image of this combination. This achieves a broadcast reception apparatus which selectively uses necessary pieces of navigation information to display an image as a user interface.

A data display control apparatus receives a digital broadcast and compares the present time with a time indicated in a Time_Event_Part provided in navigation information used to control the display of the multimedia data composing a broadcast program. When the indicated time has been reached, the data display control apparatus executes instructions to control the display of the multimedia data.
