A data intermediary system includes a processor and a storage unit. The storage unit stores, for a plurality of services used by a user in the past, provision situation information indicating data for each item of the data provided to a service provider to use the service. The processor acquires information indicating an item of data requested, by the service provider, acquires the provision situation of data of the same item as the item of the data requested by the service provider, determines that an item of the data whose provision situation satisfies a predetermined condition is provided to the service provider, and controls distribution of the data to the service provider that that holds the data of the item determined to be provided.

Data intermediary system and data intermediary method

Provided is a data intermediary system, comprising a processor and a storage unit. The storage unit stores therein usage information indicating usage of services. The processor acquires information indicating a data item that needs to be provided by a user as required by a provider of a first service that the user wishes to use, based on terms of use of the first service, selects a second service from services that the user has used in the past, based on the usage information, extracts a difference between the required data items and data items provided based on terms of use of the second service, outputs information indicating the extracted difference, and controls, when the user has accepted the terms of use of the first service, a flow of data from a provider holding the required data to the provider that provides the first service.

Digital broadcast receiving apparatus including: a receiver receiving at least three different video programs in one transport stream, including a plurality of different video signal formats having different combination of scan lines and scan method; an isolator to isolate a video signal; a decoder to decode the video signal; a processor to execute a plurality of video processing sub software programs, providing video processing according to a different combination of the number of scan lines and a scan method; a controller using information obtained from the digital multiplexed signal to determine a combination of the number of scan lines and a scan method, and selecting one video processing of the video processing sub software programs to perform video processing according to the determined combination of the number of scan lines and the scan method; and a display to display the video signal processed by the processor.

Digital broadcast receiver unit

In a video recording apparatus which records and reproduces digital TV broadcasting, an I-picture extraction processor that extracts packets containing I-pictures by analyzing a transport stream is arranged. Then, packets containing I-pictures is output, by reading predetermined amount of recorded data from an HDD in which recorded data is stored and by detecting start information and end information of the I-pictures. A stream for special reproduction is output by repeating the above-stated processes. With such arrangement, it is possible, even if data does not contain position information of I-picture, to execute special reproduction such as fast-forwarding reproduction for TV program data that is recorded as an MPEG-formatted transport stream.

Apparatus for video recording and reproducing, and method for trick play of video

A display apparatus coupled with a video processing apparatus including: an input unit which inputs a video signal scanned by one of the plurality of scanning methods and a scanning method data detected based on said video signal from said video processing apparatus, a display which displays said video signal inputted by said input unit, a controller which controls as said display displays said video signal based on said scanning method data inputted by said input unit.

In a television receiver including a video recording/reproducing apparatus therein, since reduction is quick in a recording space thereof if recording the high-definition television broadcast signal as it is, even including a recording medium, such as, a HDD of large capacity, for example, video, audio and caption data are extracted within a video extract portion, an audio extract portiona caption extract portionfrom a MPEG2-TS (Transport Stream) signal (TS=video+audio+caption data+BML (Broadcast Markup Language)+other data), but except for the BML data. And, those data extracted are recorded in a recording/reproducing portion

Video recording/reproducing apparatus and a television receiver including the same therein

A video processing apparatus including: an input device which inputs an encoded video signal; a decoder which decodes the encoded video signal having a video format which is one of a plurality of video formats to produce a decoded video signal; a processor which processes the decoded video signal by using a scanning method information of the decoded video signal, to produce a processed video signal; and an output device which outputs both of the video signal processed by using the scanning method information and scanning method information of the processed video signal, from the video processing apparatus to an external video processing apparatus.

A recording and reproducing apparatus capable of recording and reproducing the signals of both a digital broadcast system and an analog broadcast system is disclosed. By utilizing the existing configuration efficiently, the cost increase due to the system change is minimized. Both the digital broadcast system and the analog broadcast system are connected to a connector to receive both digital and analog broadcast signals. The analog broadcast signal input through the connector is recorded in a digital broadcast signal recording unit of the digital broadcast system under the control of the control unit included in the digital broadcast system.

Apparatus for recording and reproducing plural streams compressed in different formats

A digital broadcast receiver unit for determining the scanning method of the video signal of the selected program when signals multiplexed through a plurality of different scanning methods are received, processing these video signals by an appropriate video signal processor constituting a video encoder, and then outputting the result. This digital broadcast receiver unit includes a demodulator to tune in the channel of the received signal and perform demodulation, a multiplex isolator to isolate the audio, video and other types of data coded from the multiplex signals output from the demodulator, a decoder to decode the video signal and audio signal from the multiplex isolator, a plurality of video processors performing respectively different corresponding scanning methods and connected to an output of the decoder, an output selector to select from among outputs from the plurality of video processors, and a controller to control the output selector and determine the scanning method of the video signal of the selected program and also perform the appropriate processing based on the scanning method for the selected video signal.

A digital signal transmission system including a transmitter and a receiver and capable of transmitting highly efficiently compressed/coded digital video signals and receiving the video signals so that the text of emergency information or the like can be displayed together with video images without once expanding/decoding the digital video signals on the transmitter side. In this system, the multiplexer of the transmitter multiplexes digital video signals and digital audio signals with a digital information signal of text which is produced and has N-level priority information added by the information stream generator, and transmits the multiplex signal to the receiver. The receiver determines whether the text of the digital information signal is to be displayed on the basis of the priority information added to the digital information signal, and when it is determined that the text are to be displayed, the receiver can display the text of the digital information signal together with the image of the digital video signal.
