摘要:
The present invention provides a reproduction apparatus capable of automatically switching an input of a television to an output from a broadcast receiver such as an STB. A television, upon receiving a notification command notifying that output of video or audio is to start, switches its input to an output from an apparatus which has sent the notification command. An STB, upon receiving an instruction command instructing that output of video or audio should be started, sends the notification command to the television. A DVD recorder includes: a decoder that reproduces video or audio recorded in a DVD-RAM disc; a data output I/F that outputs the reproduced video or audio to the television; and a command sending and receiving I/F that sends the instruction command to the STB when the output of the reproduced video or audio ends.

When the HPD (104b) which indicated that the transmission of a control signal between the data receiving apparatus (102) and the control signal receiving apparatus (101) has become possible is detected, the command judging section (115) ignores the first reception command which it directly received from the remote controller (103) and makes the second reception command (112a) effective which it receives via the CEC line (104a).In such a construction, it is possible to conduct a remote control operation normally without affecting unfavorable influences on the apparatuses.

Detecting an input source of a signal of a device connected to a bus and determining whether the signal is converted, extracted, multiplexed, or processed. Efficiently controlling the connection of each unit connected on the bus. Issuing a command for detecting the output plug or source plug as the signal source. The unit or subunit receiving this command shows the signal source. Obtaining information showing whether a subunit is present in the unit or not.

A TV is provided for enabling a viewer to continuously watch a program which has been received even though a TV broadcast receiver is switched from a TV tuner to an apparatus for external input. A TV (131) transmits an output start instruction command to a DVD decoder (101) selected as the apparatus for external input (Step 201). Upon receiving the output start instruction command, the DVD recorder (101) transmits the output start notification command to the TV (131) (Step 202). Upon receiving the output start notification command, the TV (131) switches the input path to the DVD recorder (101) (Step 203), and transmits, to the DVD recorder (101), a channel selecting command including information showing a channel which the viewer has watched (Step 204). When receiving the selection command, the DVD recorder (101) changes the channel selection on the tuner (103) to the channel which the information showing the channel in the channel selecting command.

The network system comprises an original device description indicating a control point so as to register an address used for MAC address authentication. The server side acquires information from the device(s) connected to the network, and only the device(s) having the above mentioned description are listed and displayed. By responding to the access from the non-registered device in a predetermined manner, the device is prompted to be registered, said device corresponding with the device description, but not registered.

It is objected to simplify a procedure concerning bandwidth acquisition. Bandwidth acquiring means 809 of a second transmitting apparatus 814 acquires a bandwidth which was used by a first transmitting apparatus 806 by using a propagation delay identifier804 read from first transmitting apparatus 806 and a maximum transmission data size 805 after stopping transmission of first transmitting apparatus 806. Each apparatus is composed so that transmission is started using this bandwidth and because returning and re-acquisition are not accompanied when the transmission is switched, necessary procedure can be simplified. Further, it is possible to effectively use the bandwidth by using a propagation delay identifier.

The connection verifiable information processing system of the invention comprises: a system service 5 which outputs a first transmit request to request an output of connection information, and which processes response information to the first request, the response information being described following a first format; a WDM driver 7 which outputs a second request to request an output of connection information, and which receives response information described following a second format that a WDM compliant device 8 outputs in response to the second transmit request, while remaining unresponsive to the first transmit request; and a second FSD 13 which converts the response information described following the second format received by the WDM driver 7 into response information of the first format that the system service can process.

A multichannel display data generating apparatus displays AV data on a plurality of screens. A channel displayed on one of the screens is displayed without a program clock reference.
摘要:
A data transfer method which eliminates erroneous operation of conventional devices not supporting encryption when copy-protected AV information is encrypted and sent on an IEEE 1394 bus. Synchronous data transferred through isochronous communication contains i) encryption identification information for indicating encryption of actual data and ii) actual data. Only the actual data is encrypted. Encryption identification information indicating encryption of actual data in synchronous data is sent together with actual data from the sending device. A receiving device detecting encryption of actual data from this encryption identification information requests decrypting information from the sending device. The receiving device decrypts the actual data using decrypting information received from the sending device according to this request.
摘要:
A transmitting apparatus for transmitting a source packet constructed of a pair of data of source packet data and a source packet header including a time stamp is provided. The transmission apparatus includes transmission packet generating means of investigating values of a predetermined portion of the time stamp included in the source packet when the source packet is inputted. The transmission packet generating means unifies source packets that have a same value for the predetermined portion and are inputted in series to be outputted as one unit of transmission packet data.The transmission apparatus includes data outputting means of producing a transmission packet by adding predetermined additional information to the outputted transmission packet data and outputting the produced transmission packet outward.
