This information processing apparatus, this information processing apparatus includes a data-sending interface capable of transmitting data to a television receiver through a first transmission channel; a request-sending interface capable of sending a request to the television receiver through a second transmission channel; a second interface connectable to the television receiver through the second transmission channel; and a first control unit that detects an event and performs control to send, to the television receiver through the second transmission channel, a request including at least control information for giving an instruction about control to be executed by the television receiver in accordance with the detected event.

If an instruction is provided so as to receive second content information in place of first content information on the basis of only one operation by a user while the first content information is received through a connection formed in a communication network, the connection for communication of the first content information is disconnected, and thereafter, a connection for communication of the second content information is formed. In this manner, network resources can be reserved or released without consciousness of users.

Information receiving device and method, information release device, and information communication system

To provide a device for downloading a digital content file, an information processor stores, in an external storage device, a digital content file obtained from a server through a network through packet communication, where the information processor includes a download control section for keeping a recording area having a size which is equal to the data size of the digital content file in the external storage device and storing the packets in order from the earliest to the latest obtained, in this recording area; and a resume data generation section for generating a resume data indicating the progress of obtaining the digital content file, and the download control section stores the resume data in the subject recording area and removes the resume data from the recording area when the last packet is obtained.

A state transition of a player operation is explicitly defined to facilitate the production of interactive contents. As a player model for reproducing a disk, a model including a playerfor reproducing a stream, a platformproviding an interface between the playerand a hardware, and a script playerfor realizing a scenario intended by a content producer is conceived. The states of the playerare defined by four states defined by combinations of two states as to whether the play list reproduction is performed or not and two states as to whether the commandis accepted or not. The state transition of the playeramong the four states is generated by a methodfrom the script layer, but not by the playeritself or the command. The states of the playerare small in number, and the conditions for state transition are definite. Therefore, the interactive contents can be easily produced and mounted on devices.

Reproducing apparatus, reproducing method, reproducing program, recording medium, and data structure

A data reproducing apparatus, which is capable of reproducing stream data according to time stamps without need to have an independent time counting clock. At step S, it is determined whether a received access unit has a time stamp. When the access unit has a time stamp, the flow advances to step S. At step S, a value of the time stamp is set. When the access unit does not have a time stamp. The flow advances to step S. At step S, a value corresponding to the previous pic_struct is added to the current time. Thereafter, the flow advances to step S. At step S, the current pic_struct is stored for the next process. The present invention is capable of being applied to for example a game device using a DVD.

A variable speed reproduction is accomplished without sacrifice of picture quality. A controllercreates EP_map( ) in a clip information file with an address of RAPI extracted by an RAPI information extraction unit, PTS of an intra-picture immediately preceded by RAPI, and one of end positions of the intra-picture and second, third, and fourth reference pictured preceded by the intra-picture and stores EP_map( ) to an output server. In other words, the controllercopies a value close to a predetermined sector count (the number of sectors that can be read at a time in the encode process) of the end positions of the four reference pictures (1stRef_picture, 2ndRef_picture, 3rdRef_picture, and 4thRef_picture) to N-th_Ref_picture_copy, decides index_minus1 based on N-th_Ref_picture_copy and records it on a disc.

To facilitate implementing a user operation control in a picture reproducing apparatus for reproducing contents recorded on a disk or the like. A picture reproducing apparatus selects and reproduces a plurality of prerecorded picture streams in the disk. A reproduction control unit is configured to reproduce the picture streams in either of two reproduction modes, i.e., a normal mode for accepting particular key inputs pertaining to picture reproduction and a menu mode for not accepting the particular key inputs. The mode in which the picture streams are reproduced may be written by contents creators in a script file which is recorded on the disk.

Picture reproducing apparatus and method, recording medium, and picture reproducing program

A reproduction apparatus has a player section, a content reproduction section, an interface section. The player section has a read section reading data from the record medium on which the content data containing at least one of a video data stream and an audio data stream and a reproduction control program controlling the reproduction of the content data are recorded, an input section accepting an input from a user, and an output section outputting the reproduced content data. The content reproduction section reproduces the content data according to the reproduction control program. The interface section interfaces among the content reproduction section, the reproduction control program, and the player section. When a command representing an end of the reproduced content data is described in the reproduction control program, the reproduction control program supplies the command to the interface section and the interface section executes a process corresponding to the command.

Reproduction apparatus, reproduction method, reproduction program, record medium, and data structure

A record medium is disclosed. The record medium that is readable by a computer device and on which content data that contain at least one of a video stream and an audio stream and at least one resource file that contains a reproduction control program that controls the reproduction of the content data and data used by the reproduction control program are recorded. The file name of the resource file contains information that represents a language that is normally used when the content data are reproduced and information that represents a language attribute of the resource file.

A data communication protocol is implemented to control data flow between a transport layer and a data link layer. The protocol provides two manners of data flow control. (1) In the first control manner, when the occupancy of packet buffers of the data link layer is smaller than a first threshold, the data link layer informs of the transport layer that the packet transport should be suspended, and thereafter when the occupancy is smaller than a second threshold smaller than the first one, the data link layer requests the transport layer to resume the packet transfer. (2) In the second control manner, when the amount of packets is smaller than a value determined based on the transfer rate and maximum burst size, the transport layer transfers a packet to a lower layer, and when the packet amount is larger than the value, a packet is transferred after a predetermined time passes to control the transfer rate to a predetermined one.
