摘要:
A sending receiving method for data, such as musical data, in which plural data stored in a first storage unit are retrieved based on the request information sent from a host side device. The retrieved data is sent to a terminal side device. The sent data is checked to see as to whether or not the sent data is data newly stored in the first storage unit. If the results of check indicate that the sent data is data newly stored in the first storage unit, the sent data is stored in a second storage unit of the terminal side device.

A method, a computer readable medium, and a data system are provided for indicating when a superseded data file in a series of data files has been replaced with a changed data file. An index file is created and inserted in the series of data files. The index file includes a change indicator signifying that the changed data file has replaced the superseded data file. The index file is repeatedly transmitted with the series of data files.

The present invention is related to a communication system in which a transmitter (2) transmits cyclically a plurality of mutually related objects (20,22,24,26) to a terminal (10). If said objects are used in the terminal there is no mechanism to establish whether said objects are consistent, e.g. that they are originated at the same time. To ensure that the objects are consistent, they are combined in a common transport entity. The receiver is arranged to extract only the complete set of mutually related objects from the common transport entity. Consequently, the consistency is always ensured.

The disclosure relates to a recording and reading apparatus constituting a kind of video reservoir in the home of the consumer. Thanks to a large-capacity storing technique with suitable technical means, broadcasters transmit numerous programs via specific channels and the consumer may control the content of his reservoir (by recording, reading and erasing programs). The invention is applicable to on-demand video in the consumer's home with a video reservoir constituting a video-library that is regularly updated by broadcasters and/or by the consumer himself.
摘要:
A broadcast system architecture implementing a method for distributing data for a multi-user application (e.g., a shared virtual world) between client systems. Included are a plurality of server systems communicatively coupled in a network and a digital broadcast source. A first group, a second group and a third group of client systems are communicatively coupled to the server systems, wherein a client system is coupled to a single server system. The first group and second group of client systems execute a partition of the multi-user application. Data are forwarded from a client system in the first group of the client systems to a first server system, wherein the data represent a change to the partition executed by the client system. The data are forwarded from the first server system to other server systems, wherein the other server systems each comprise at least one client system that interfaces with the partition. The data are forwarded from these other server systems to the second group of client systems interfacing with the partition. The data are also forwarded from the first server system to a broadcast source. The data are broadcast from the broadcast source to the third group of client systems not presently interfacing with the partition. The broadcast source distributes the data rapidly to a large number of users so that the consistency of the multi-user application is maintained for all users.

An object is to make efficient pre-reading possible even in receivers having little memory for receiving. A CPU 147 acquires data size in each module by referring module control information for a received DII, (step S39). The data sizes of the modules are compared with the remaining memory in a RAM 144 (step S45), and modules smaller than the remaining memory are pre-read into the RAM 144 (step S47). When a pre-read flag is not on, then no pre-reading is done even when a module is smaller than the remaining memory. Thus data that are updated from time to time can be excluded from being subject to pre-reading.
摘要:
An information method and system enables information, from a set of original information which is updated at regular or irregular intervals, to be provided to each information receiving apparatus of respective users via a data transmission path which can be selected in accordance with the type of data to be transferred, stated preferences of the user with regard to providing of data, current operating status of a data communication network, etc. A set of framework data are selected as data which are rarely updated, by monitoring original information that is to be provided, over a suitably long period, and are stored at the information providing apparatus and each information receiving apparatus. Thereafter until a new set of framework data are selected, any differences between newly updated original information and the framework data are obtained as variation data, and transmitted to be stored at each information receiving apparatus, which can reconstitute desired data on request from a user by combining appropriate parts of the locally stored framework and variation data, thereby minimizing the amounts of data which must be transmitted to the information receiving apparatuses.

To provide a control program downloading method that is used by a digital broadcast receiving apparatus equipped with a storing device which stores an update program and a non-update program that compose a control program. Under control of the update program, a new update program is received and written over data stored in a part of an area in the storing device where the non-update program has been stored. At the same time, a part of a new non-update program is received and written over data stored in another part of the area in the storing device where the non-update program has been stored. Once the new update program has been completely written into the storing device, under control of the new update program, the reception and writing of the part of the new non-update program is continued.
摘要:
A broadcast content that is at least a part of an original content is broadcasted, and a differential content, which is at least a part of the original content, is transmitted in response to a request from a reception terminal. The differential content and the broadcast content are merged with each other to reproduce a perfect original content. Therefore, the perfect original content can be obtained at low price and in short time even when the original content contains a large amount of data.
摘要:
An information dissemination system comprises an Internet-connected server adapted for gathering information from plural sources, and sorting the information according to subscriber preferences. The sorted information is transmitted via the Internet to a subscriber's Internet Applicance (IA) as electronic documents, where the documents are downloaded to a connected playback device. The playback device may be disconnected from the PC, and the information electronic documents rendered as speech to a speaker in the playback device by a text-to-speech system. In a preferred embodiment annotation is added at the Internet-connected server to control speech characteristics, such as inflection, upon playback. In some embodiments updates may be made by radio with the playback device disconnected from the IA.
