Description

DEVICE AND METHOD FOR THE TRANSMISSION OF MULTIMEDIA DATA OBJECTS

The invention relates to an apparatus and method for transmitting multimedia data objects from a central Datenguelle via a data network to a plurality of terminals, preferably televisions, which are connected via an additional device to the data network, which from the central data source via a central power injector in be implemented a system suitable for data transmission format and fed to the data network, wherein it is in the central power injector to a Transkodie- rer, which digitizes the related from the central data source data objects and converts them into a digital data stream and that data stream via an interface continuously in feeds the data network and transmitted to the connected auxiliary devices.

Such a device and such a method are already known from the international application WO 00/38430 Al. The int. Application relates to an apparatus and a method with which it is to be possible for users video data and Weppages in separately or in combination with a common terminal, gene preferably to be received a TV. For this purpose, from a central server, the video data in a MPEG2 data format converted and transmitted to a digital set-top box with a MPEG2 decoder. The clients can also perform Internet functions by means of a entsprecheden software. A distinction is made between a one-way video reference and a two-way video reference. Only the two-way relation allows to influence the client interactively on the playing modalities of related video clips.

Here, the MPEG2 standard has indeed been an excellent image quality but the possibilities of data compression must be regarded as limited. The data transmission bandwidth required is therefore substantial. In lower bandwidth of the transmission channel corresponding restrictions on the playback quality will have to be tolerated.

Basically, for some years the effort to open even those users to access the Internet, either have no computer and / or are not familiar with its operation. Especially with the increasing functionality and expansion of the Internet is a need conventional and widely used devices to make Internet-compatible. In this context, set-top boxes have become known so-called, which include converting essentially a web browser based on the Internet data in a common format for televisions. The owners of such additional equipment can therefore at least largely be used with a conventional TV set internet.

Basically m SEN can such set-top boxes using the TCP / IP protocol to communicate and implement the commonly received in the form of HTML files into signals suitable for display on the TV set format. Here, such set-top boxes can be equipped with a number of Zusatzfunktionalitaten, such as a dedicated processor, random access memories, buffers, among others, to provide a number of additional functionalities ready. The disadvantage of this set-top boxes has existed since time immemorial in their relatively high price.

Starting from this problem, a solution according to WO 98/50862 AI aims to reduce that price by the fact that the functionality of the set-top box essentially to a central Einspeisegerat is verla- siege here to a video server. is taken the more functionality, for example, in connection with the required transformation of the data from a central video server to the connected set-top boxes so easier and cheaper can be designed.

In connection with the transmission of multimedia data objects, such as moving picture data, video data or sound data accompanying it has been shown that the packet-based transmission according to the TCP / IP protocol of the Internet is unsuitable per se. The transfer of picture and sound takes place intermittently, as a rule, so that a ruckeln- of image or sound interruption stan-ended and thus give a high unsatisfactory result. It is prior art to solve this problem in the way of greater data rates, for example, by the use of ISDN telephone lines. This solution leads to an improvement of the representation, but does not eliminate the principle existing problem.

The invention is therefore based on the object to provide an apparatus and a method for transmission of multimedia data objects that avoids the aforementioned drawbacks of the prior art and provides an improved picture and sound quality of the transmitted multimedia data objects the end user.

This object is achieved by an apparatus and a method according to claims 1 and 10. FIG. Advantageous embodiments of the apparatus of the invention will become apparent according to the dependent claims 2 to. 9

This object is achieved in that first a digitalization of multi-media data objects is performed according to the main claim with a central power injector, and then this data stream is converted into a continuous data stream. The used for this purpose streaming technology is known as such in connection with Internet applications. This known technique is used to in the context of the invention to not been able to use Internet-enabled devices in an improved quality. The crucial aspect of the invention is to use this technique in connection with a central power injector for transmission of multimedia data objects, and to transfer by means of the decentralized equipment is turned in such a fed multimedia data objects in a simple manner to remote terminals such as television. The auxiliary device then sets the received digital continuous data stream into a television image and brings this to the connected terminal device for display. Moreover, it is is an essential aspect of the invention to design the attachment user side to be used as economically as possible, it is considered advantageous that the attachment is indeed provided with an interface for receiving the input data about a user, but by the auxiliary device itself does not Such data is done but only one transmission to a transcoder.

The transcoder can edit it in one place a variety of different data formats and convert them into one or a few formats for feeding into the data network. This ensures the need to master the decentralized accessories only these few formats. The introduction of new standards so requires only retrofits in the field of central Transkodie- tion.

In an advantageous refinement of the transcoder provided for this purpose is provided with a so-called codec interface. The term "codec" is an abbreviation for a com- pressor- / decompressor technology. This includes interfaces are understood to possess a special driver that allows the compression and decompression of data. By codec interfaces, large amounts of data, particularly as they are manageable in connection with audio and video data are compressed and consequently with lower

Bandwidths are transmitted in the data network. In an advantageous embodiment, the supplemental device is able to decompress the compressed data stream received.

However, it may be advantageous if the Benutzerauto- ization with the aid of a conventional chip card at the remote device is possible. For this purpose, the auxiliary device may be equipped with a respective reader. The data is read out remotely. The actual verification is done centrally.

The auxiliary device can be simplified further characterized in that a pre-assembly of the related multimedia DA of the centrally disposed transcoder substantially tenobjekte is carried out for a representation on a TV. In particular, an adaptation of the multimedia data objects to the optical resolution of a TV set is performed. Thus, the multimedia database objects are line-oriented and in a manner adapted to the television picture line number already processed by the transcoder. In this way the conversion of the received data stream from the auxiliary device is facilitated.

Another pre-assembly of the television set by the transcoder is effected in that the multimedia data objects are already transferred in the usual in television technology red, green, blue-coding or YUV coding from the transcoder. In yet an advantageous embodiment, transmitted about individual objects, are already combined in such a way by the transcoder or changed in their layout that a representation on a TV is possible or useful.

In order to facilitate the operation as a digital video server or the transcoder, in general, a virtual control panel is provided that can be invoked by the user via the auxiliary device and then operated by the transcoder. The control functionality is therefore not provided with the adapter, but rather from the central transcoder. This makes it possible to make do the locally established accessory essentially without their own processing power.

The invention is explained hereinafter with reference to the drawing of an embodiment illustrated only schematically.

Show it:

Fig. 1 shows an apparatus for transmitting multimedia database objects to a TV in a block diagram.

The block diagram shown in Fig. 1 shows a centrally located transcoder 1 which is connected via a data network 2 with an addition device 3 in bi-directional data connection. To the auxiliary device 3 is a terminal, a television set 4 connected here. The user of the television set 4 can be either a remote control 5 or via the television 4 with the auxiliary device 3 then via a corresponding input interface 6, to communicate. The centrally erected transcoder 1, which is connected via the data network 2 with a plurality of additional Advised 3 and thus of Endgeraten in data connection is in turn connected to a data source 7, which contains the related from the transcoder 1 of multimedia data objects. The multimedia data objects 7 can be essentially still images in black / white or color, acting texts with different objects, moving images such as video or audio data with or without synchronous relation to a video. Typically, the multimedia data are mentioned in various forms, so that the transcoder 1 has different interfaces 10 to 12. In the present example, these are to a video interface 10, an Internet interface 11 and a non-close-defined peripheral interface 12th

The transcoder 1 is provided with a codec interface 13 for compressed feed of the continuous and digital data stream. The zusatzgerat 3 has a bi- directional data interface 14 that allows at least a decompression of the received data stream. By means of the additional device 3 is performed in addition to a decompression of the received data only one implementation of the data stream in a suitable for display on the TV set Tonsi- gnal 15 and image signal sixteenth

Hereinafter, the operation of the apparatus described above will be explained in more detail:

First, a selected multimedia data object is compressed based on the data source 7 and is converted by means of known per se streaming technology in a continuous Chen digital data stream which is transmitted via the data network 2 to the data interface 14 by the transcoder in accordance with receiving user preferences. The additional device 3 decompresses the received data stream and sets it for display on the TV 4 suitable audio and video signals 15 and 16 in order. The auxiliary device 3 can be operated in a known manner, either with its own remote control unit 5 or the remote control of the TV. 4 In particular hereby the transcoder 1 can be addressed in such a way that, if necessary, a virtual loading is serving panel transmitted to the auxiliary device 3 and arrives in analogy to the above explanation on the TV 4 for display. facilitating the entry of user data can then be performed using the remote control 5 and shown on TV 4 virtual control panel. Examples of play can be queried in this way, authentication of the user or more accurate data to the reference of the addressed multimedia data object.

Specifically, this can occur such that a user 21 first be activated accessory device 3, and thereby first conventional per se IP data connection to a control center 20 having a plurality of transcoders 1 and the data source is established. 7 The parameterization and authentication of the user 21 may zerdaten by entering the user-or by reading out a corresponding code card. For this purpose, the auxiliary device may be provided with a smart card reader. 3 For this purpose must be between the control center 20 and the user 21 is a data connection with a minimum - 500 KBps be prepared bandwidth. Such a bandwidth is only achieved in the moment by means TDSL- lines or so-called cable modems. Once it is determined the access authorization from the control center 20, in particular the collecting data have been checked, is selected by the center 20 of one of the transcoders. 1 The user can then select 21 via the already mentioned virtual control panels a multimedia data object from the data source. 7 a specific interface 10 to 12 of the transcoder 1 will be activated in dependence upon the data selected object. In each case a continuous digital data stream is generated in particular by the current MPEG4 standard. The image and sound data are then transmitted via a UDP protocol in place of conventional packet-based data connection to the accessory. 3 The additional device 3 decompresses the received data stream and translates it into analog signals which can be transmitted to the television 4, in particular at the Scart socket.

Depending on the equipment the auxiliary device 3 with additional functions such as fast forward, rewind, still, or special control panels can be configured for video games. Here, the respective control inputs via the input are cut parts 6 transmitted to the transcoder. 1 This converts the received commands to control functions, to be transmitted to the data interfaces 10 to 12 corresponding to the control of the data source. 7

Above an apparatus and method is described thus by way of example, that the user side provides functionality with a very simple design accessory 3, which offers the traditional set-top boxes standard clear.
