摘要:
A reproduced image transmission apparatus which can display reversely reproduced images normally even when the transfer order of asynchronous transfer and isochronous transfer is not ensured on IEEE1394, in cases where an apparatus for generating the reversely reproduced images and an apparatus for decoding the reversely reproducing images are connected with each other via an IEEE1394 network. An MPEG transport stream processing means 15 embeds control signal for controlling decoding in an MPEG picture, and transmits the signal together with the MPEG picture through the IEEE1394 network in the isochronous transfer mode, whereby the synchronization between the MPEG picture and its control signal is surely obtained, thereby to generate reversely reproduced images according to MPEG using P and B pictures.

Alternation processes reduce the recording and reproducing speed of a hard disk apparatus.A hard disk apparatus comprising: an HDD 10 for recording AV data onto a hard disk; and stream controlling means 8 which is connected to the HDD 10 and thereby processes the signal of AV data transmitted from an IEEE1394 I/F 7 or the signal of AV data transmitted to the IEEE1394 I/F 7; whereby the hard disk apparatus can record and/or reproduce the AV data, wherein when AV data transfer is not normally completed for a disk access unit which is a minimum continuous unit in the access to the hard disk, an alternation process on a disk access unit basis is carried out so that another disk access unit is used hereafter in place of that disk access unit.

In jumping reproduction, when an MPEG transport stream processed by the jumping reproduction is decoded and displayed, many noises occur in the video and the audio corresponding to the vicinity of the jumping.Provided are: a hard disk section 208 of reading and reproducing AV data recorded as an MPEG transport stream in a recording medium; and an AV transfer control block 211 of controlling the hard disk section 208 in such a manner that during the reproduction of the AV data, when the reproduction is performed with skipping a predetermined portion of the AV data, before the skipping of the predetermined portion, transport packets are outputted up to the last one among those constituting a frame, and that after the skipping of the predetermined portion, transport packets are outputted starting from the beginning transport packet of the next I frame.

Conversion of audio data is performed such that a bit stream conforming to the DVD-VR standard is converted into a bit stream conforming to the DVD-video standard. A stream converter includes: a first converter for receiving a bit stream conforming to a DVD-VR standard, converting data except for audio data in the bit stream into data conforming to a DVD-video standard, and outputting a resultant bit stream; and a second converter for converting, when the audio data in the bit stream output from the first converter does not conform to the DVD-video standard, the audio data into data conforming to the DVD-video standard, and outputting a resultant bit stream.

A transfer rate controller, has input means of inputting a picture or sound stream; packet rate adjusting means of controlling a transfer rate of the stream by adjusting an interval between packets respectively belonging to each frames of the inputted stream; and output means of outputting the stream outputted from the packet rate adjusting means.
摘要:
In a content distribution system, a recording-management system makes a storing section of a first terminal device store a predetermined content stored in a content-storing section of a distribution device obligatorily. Under this condition, when a second terminal device requests the recording management system to distribute the predetermined content, the recording management system transmits the address identifying the first terminal device that stores the predetermined content to the second terminal device. The content stored in the first terminal device is transmitted and received between the second terminal device and the first terminal device having the received address through a user network to obtain the predetermined content. Thus, the content requested by a given terminal device can be distributed to the terminal device that has made the request without increasing the scale of the distribution device.
摘要:
A special reproduction data generating device is provided. An MPEG transport stream is input to the special reproduction data generating device. The device includes a special reproduction data generator for directly generating special reproduction data by selecting a transport packet including data of a predetermined kind of frame from transport packets of the MPEG transport stream, without converting the inputted MPEG transport stream to an ES (elementary stream) or PES (packetized elementary stream). The special reproduction data generating device outputs the special reproduction data as an MPEG transport stream.
