Abstract

A television signal (digital or analog) is transmitted from a TV transmitter (104) to the user's receiving device (108). In parallel, the central server (102) generates a data signal (204) based on synchronization information of the TV transmitter. This contains a first URL to an Internet page (208), and at least a second URL, which leads to additional information to the television signal (202). The data signal (204) is transmitted as part of an XML feed over the Internet to the receiving device (108). The Internet access receiving device (108) loads the Internet page associated with the first URL into a memory. At a defined point in time, when information accompanying the TV program is to be offered (for example in a commercial), the television signal (202) and the website (208) are visualized in overlay mode on the display (110). By means of a remote control, the user calls upon request by clicking a button (linked to the second URL) on the visualized website (208) program-accompanying information via the Internet (216). From this point on the current television signal (202) is recorded. Upon completion of viewing the information from the Internet (216), the television signal (202) is displayed on the display (110) at a time lag.

Description

Field of the invention

The The invention relates to the field of interactive television.

State of the art

The Internet already combines the various media, such as writing, Picture, sound and film. The display of the common in the Internet Documents are usually made on computer monitors. With an aspect ratio of 4: 3 are high quality Models already able to display the desired information, for example with a resolution from 1600 × 1200 To represent pixels. A TV picture in the PAL standard corresponds to only one resolution of 768 × 576 Pixels.

With the introduction High Definition Television (HDTV) The worlds of TV and PC continue together, with HDTV as a collective term a series of television standards referred to the usual Television (standard definition TV; SDTV) by an increased vertical, distinguish horizontal and / or temporal resolution. The HDTV now offers in Full-HD one of the high-quality computer monitors comparable resolution from 1920 × 1080 Pixels, and there are already many computer monitors with the aspect ratio 16: 9 (1.85: 1) and a full-HD resolution in the Trade. Full HD ("Full High Resolution") mostly the property of an HDTV capable device (TV, DVD player, Set-top box, game console, etc.), the highest possible HD resolution to spend. Therefor For example, a TV can have a real physical resolution from 1920 × 1080 Pixels or a high resolution DVD player for this resolution indeed required signals completely output.

Since the introduction of digital television, set-top boxes have emerged that can receive digital television signals over various transmission paths. As transmission paths are common:

• - DVB-T (Digital Video Broadcasting-Terrestrial, which refers to the terrestrial distribution of digital television signals),
• - DVB-S (Digital Video Broadcasting Satellite, which refers to the distribution of digital television signals via satellite),
• - DVB-C (Digital Video Broadcasting Cable, a variant of DVB used for the transmission of digital value-added services over cable, usually the digital distribution of television signals),
• - DVB-H (Digital Video Broadcasting Handhelds; refers to a broadcasting standard used to receive digital broadcast programs and multimedia services via small and / or mobile devices) and
• - the Internet.

It Today, in addition to the analog television signal, digital standards for all transmission paths are available.

digital TV over that already for the internet in use Internet Protocol occupies a special position, because in the context of the IPTV (television over Internet Protocol) there are also interactive TV applications. IPTV is usually offered by means of a closed data network. For IPTV, especially at full HD resolution, A particularly high bandwidth is required for moving pictures and tone required amount of data to be transmitted smoothly.

by virtue of new video data compression techniques and broadband Internet access it increasingly possible Watching TV or videos too the public Internet offer. This special form is called Internet TV. Although for the public Internet already has enough bandwidth available, it is not possible on the public Internet IPTV with guaranteed quality transfer, as the Internet provider guarantee no minimum bandwidth. Therefore, the public offers Internet no function guarantee for the transmission of TV content.

An online essay titled "Interactive Television" (Hall, GS, Mix Professional Audio and Music Production, 2002, http://mixonline.com/sound4picture/filmtv/audio_interactive_television/) describes a process in its chapter "ITV Technologies." for enabling interactive television. In this case, a common television signal from a TV transmitter is received by the receiving device of a user as well as a data signal independent thereof from a central server (eg via an internet connection). The Data signal contains additional information to the television signal, which has an indication of additional accompanying the program additional information that the user if necessary with the help of the receiving device z. B. via the Internet can call.

A pamphlet US 2003/0 189 668 A1 Boston, USA (Newman et al., Boston, USA, 2003) discloses a method for synchronizing interactive content within a broadcast signal or independently of the broadcast signal for a user (user) are provided via a suitable terminal.

Also another pamphlet US 2004/0 210 824 A1 "Interactive entertainment system for presenting supplemental interactive content together with continuous video programs" (Shoff et al., USA, 2004) describes an interactive television system that facilitates the presentation of additional interactive content in addition to traditional broadcast video programs such as video broadcasting. B. TV shows and movies. The broadcast programs are transmitted in a conventional manner. The additional content may be transmitted as part of the program signal via the broadcast network or separately via another communication network. The additional interactive program content can be detected via a receiving device located at the user and made available to the user on demand or automatically for use, eg. B. with the help of an internet browser.

A method for the realization of television with "time shifting" is used for example in the. pamphlet EP 1 515 341 A2 "Method for a time shift display of a video signal and apparatus" (Barron, Steven Anthony, Carmel, USA, 2005). In the described method, the display of a recorded video signal is started with a time delay, while the further recording of the received video signal is still taking place.

task

task The invention is to realize interactive television applications without the for IPTV and DVB-H required expansion with appropriate bandwidths or Quality of service to propagate a TV signal.

solution

These The object is achieved by the inventions having the features of the independent claims. advantageous Further developments of the inventions are characterized in the subclaims. The wording of all claims is hereby incorporated by reference into the content of this specification. The invention also includes all reasonable and especially all mentioned Combinations of independent and / or dependent Claims.

in the Below individual process steps are described in more detail. The steps have to not necessarily be performed in the order given, and the method to be described can also other, not mentioned Steps have.

at the method according to the invention to enable From interactive television, a television signal from a TV transmitter to a receiver of a User transferred.

Of the Interactive television users can be a television viewer, a computer user o. a. be. The TV signal from any TV station will through the receiving device z. B. directly digital via DVB-T, DBV-S or DVB-C received or analog via a cable TV system or terribly over Antenna. The receiver is advantageously designed as a set-top box, as a TV set, as a personal computer o. Ä. Also The TV reception with mobile devices (laptop, mobile phone, etc.) is possible.

Independent of TV signal is added a data signal from a central server of an operator to the Transmit receiver. The transfer the data signal of the central server via the public Internet. The receiving device has for this Purpose over Internet access. Thus, the data signal of the central server via a from the TV transmitter independent transmission path, namely the Internet, transmitted. For example, but the transmission the data signal via DSL or UMTS possible.

The data signal of the central server contains to the programs of the various TV channels ever because a first URL that refers to a website that contains at least one second URL that leads to additional information to the respective television signal or program broadcast on it.

Also contains the data signal of the central server temporal information, the specify when the web site associated with the first URL will be at the same time to visualize with the television signal.

The receiving set gets the one belonging to the first URL Website and save it.

The receiving set evaluates the information contained in the data signal of the central server with the first URLs of the accompanying web pages and loads (automatically or optional) that to the current program of the television viewer selected Belonging to TV station (s) Website (s) in the store.

As soon as in the TV signal a for the interactive television relevant content (eg commercial) is broadcast, the television signal in the receiver is synchronized in time (and thus also in terms of content to the TV program) with the first URL corresponding internet page superimposed and on display (eg TV set, Monitor of a PC or similar) transparent (overlay mode) displayed together with the television signal. Usually will be included realized in the background, the current representation of the television picture and in the foreground the semitransparent to the first URL appears associated Website.

alternative can the television signal and the website also spatially offset each other are displayed.

The belonging to the first URL Website contains at least one or more second URLs leading to the TV program further information. To has the first web page displayed on the screen or more for the user visible defined areas, each of which with linked to at least one second URL. This defined Area can be used as selection element, as hyperlink, graphic element, String, text, frame, button o. Ä. Be Recognizable.

At least a defined section of the website, which has one of the least linked to a second URL is, is clicked with the help of a cursor on the display and then the information associated with the second URL will be displayed on the Display visualized.

to Selection of additional information, the user has a Remote control, for example a remote control with function keys to move a cursor or mouse pointer. When activating (moving) The cursor will appear on the display of the function keys. With help The function keys allow the cursor to move to the selection item for the additional Information on the TV signal and this activated (clicked) become. The clicking can z. B. by pressing preset function keys remote control or with a joystick. This will the website with the information accompanying the TV program called.

simultaneously by calling the website becomes the current television program interrupted and it starts recording the other linear TV program. If the current TV program was interrupted, then the user can do the original linear TV program with a time lag look at, if the interactive Usage has ended. The recording of the television signal can in the receiver or a connected device done, but also externally via the internet on central storage devices.

In addition, can for example, the television signal after calling the desired website reduced in size shown on the display (eg picture in picture display; Pip).

With It is also possible to use interactive television in the proposed procedure without having to change the television signal, e.g. B. an SDTV signal to arrange on an HDTV monitor and next to the accompanying information from the Internet.

advantageously, All synchronization information is provided by the TV channels involved (in particular the temporal information) to the central server. From this synchronization information, the temporal information which specifies when the web page associated with the first URL in overlay mode along with the TV signal on the display to visualize is.

• – eine TV-Sender-ID (Senderkennung),
• – Angaben zu ausgestrahlten Programmteilen,
• – die Sendezeiten (von – bis) der für das interaktive Fernsehen relevanten Programmteile (z. B. Werbespots etc.).

The synchronization information provided by a TV transmitter contains e.g. B. following Anga ben:

• A TV station ID (station identification),
• - details of broadcast program parts,
• The transmission times (from - to) of the program parts relevant to interactive television (eg commercials, etc.).

The Synchronization information ensure that the TV program accompanying information fitting and in sync with the straight in the Television signal emitted program content visualized or can be retrieved from the Internet.

It is advantageous in addition for recording the television signal received from the central server and for a TV program relevant information is stored.

Also it is advantageous that the recording of the television signal including Additional information is transmitted with the television signal become. This additional information in the television signal are analog Broadcast television in the vertical or horizontal blanking interval, or multiplexed with the TV data stream in digital television.

Thereby become the linear TV program, all on this program related information and all further, contained in the television signal information to the end the use of over the internet selected Accompanying offers saved. In addition to image and sound are the data, the accompanying transferred especially the data for the interactive control of the respective Program and other accompanying information included in the blanking interval of a analog signal or as part of a multiplexed digital data signal become.

The creates the opportunity that after completion of an interactive use of the user the original linear TV program time-shifted and based on the data also stored Again, you can choose an accompanying offer with this TV program was offered. The storage of the accompanying information and the resulting possibility for delayed use is advantageously also when the user records the TV program from the beginning to view it later.

The Data signal of the central server is in an advantageous embodiment of the invention as part of an XML feed. Such feeds are also used as a service on websites, for example used to content from information providers other web pages to disposal to ask, for. B. News in ATOM format.

The published XML data feeds (content) are from the user's device (receiving device) in periodically loaded. So it is a so-called. Pull service, d. H. Data gets through a user-side activity (Terminal) fetched and not by an activity of the provider automatically sent. Similarly, the provider does not have subscription management required. The update occurs for the first time at power up of the terminal and subsequently at a time interval, for example all 20 minutes.

In An advantageous embodiment of the invention becomes an ATOM comparable format proposed specifically for the supplement of the TV program with additional Information was developed (hereinafter called TVEED). This Feed, as well as an ATOM feed, will be downloadable on the servers offered. Acts as a "reader" usually the set-top box or the program installed on the computer of the terminal is and connects the TV signal and the websites.

Such a TVEED XML stream may, for example, have the following content:

• 1) eine überregionale Kennung des TV-Senders, die auf der Basis einer Regional-Tabelle auf den jeweils lokal für den gewählten Übertragungsweg richtigen Sendekanal zeigt.
• 2) die Startzeit
• 3) die Endzeit
• 4) die erste URL.

This example XML stream can be replaced with any other format. Important are the following data that must be present for each entry (see tag "spot"):

• 1) a national identifier of the TV station, which shows on the basis of a regional table on the respectively locally for the selected transmission route right channel.
• 2) the start time
• 3) the end time
• 4) the first URL.

• 1) eine individuelle ID des Eintrags, die auch bei Änderungen beibehalten wird
• 2) eine Information über den Status des Eintrags, z. B. ”new”, ”keep”, update”, ”delete” (Einträge, deren Ende-Zeit in der Vergangenheit liegt, werden automatisch gelöscht.)

In addition, the following fields may be appropriate:

• 1) an individual ID of the entry, which will be retained even if changes are made
• 2) information about the status of the entry, e.g. Eg "new", "keep", "update", "delete" (entries whose end time is in the past are deleted automatically.)

in the TVEED format, these fields are mandatory.

Any can additional fields added become. For TVEED there are the optional entries "program" and "info". The entries for "starts" and "ends" (end) can omitted if status = "delete".

When Part of the TVEED format becomes the supplier / producer in the XML stream of the record, a timestamp of the generation and a Date for the end of validity all contained data as well as a country / region code. This information are for the TVEED format required.

Cheap, if with the help of given HTML commands the arrangement of the Television signal and the presentation of the Internet pages on the display to be controlled. This will be explained in more detail below. It This can be achieved, for example, by insertions of additional Information can be realized at the edge of the television picture.

Also it is advantageous if the television signal to be visualized and the website to be visualized is visualized scaled. This functionality allows the displayed website and the received TV signal to the respective terminal adapt. The terminal this can be a mobile device (eg mobile phone, laptop etc.), or any standard TV set (eg also HDTV suitable).

meaningful It is also that, if the television signal at the time of the call the second URL is already recorded, a reentry point for one latter time-shifted visualization of the television signal is stored. This will make it possible that the visualization of the recorded television signal is delayed can be done from the reentry point, if viewing the visited Internet pages is finished. The consideration of the current TV program can thus time-shifted (time-shifting) continues become.

If the TV signal not already from the beginning of the television program is recorded, playback of the television signal starts Leaving the Internet de facto with the beginning of the record, the when the internet was started. But if the television signal was already recorded when the webpage to the second URL was called, then it is not necessary at this moment to start a recording. It is sufficient in this case, the reentry point for one latter time-delayed return to save in the current TV program.

This i. d. R. especially if more than once a website is called, since already starting from the first call an accompanying Information a recording of the current television signal takes place and the user already time-delayed a recording of the television signal When considering viewing the accompanying web site completed.

1 shows the components of the overall system for implementing the proposed method for interactive television. It includes the central server 102 the operator (service provider), the TV station 104 as well as the user equipment (user equipment) 106 , which is required for the reception and application of the interactive television at the user. The user equipment 106 points in the illustrated advantageous embodiment, the following elements:

• • a set-top box (receiving device) 108 .
• • a TV (display) 110 , such as
• • a remote control 112 for controlling the set-top box 108 by the user

The data or information exchange between the TV station 104 and the central server 102 the operator will over the connection 105 realized. About this connection 105 In particular, the exchange of information with regard to temporal and content information to the program sequence of the TV station takes place 104 or the corresponding synchronization between TV channels 104 and by the central server 102 submitted URLs.

The relevant data for the set-top box 108 the user will be in the central server 102 prepared by the operator. The relevant data includes at least:

• • the TV station,
• • one to scene, advertising or broadcast associated first URL and
• • Start and end time ({Start, Stop), {from | to}) of the first URL page 208 or the button or hyperlink with the second URL.

A data set sent from the central server to the set-top box could be e.g. For example, have the following form:
{Start time | end time | content with ID number ID | TV channel | first URL to the overlay image that matches this content}

The transmission of the television signal 202 or the data signals 204 (please refer 2 ) by the interactive television operator on two completely separate information paths 114 . 118 to the receiving device 108 the user.

The interactive television operator provides the user with his services via the Internet connection 114 . 115 between the central server 102 of the operator, the internet 116 and the set-top box 108 available to the user. To the Internet are any web server 117 connected. Via the internet connection 115 the user receives the information from the central server 102 the operator or he calls data and information from the Internet 116 from.

The transfer of processed information from the central server 102 the operator to the set-top box 108 The user is preferably done as part of an XML feed, for example in the described TVEED format, over the Internet 116 ,

The TV signal from the TV station 104 becomes a set-top box 108 of the user over the connection 118 transfer. The connection 118 is designed differently, partly via radio and associated transmission masts and receiving antennas, either analog or digital via DVB-T or DVB-S, or analog or digital via a cable TV system.

In the set-top box 108 the data is taken from the central server 102 and from the TV station 104 processed. That in the set-top box 108 received television signal and on the basis of the data signal from the central server 102 the operator's edited website will be the user of the set-top box 108 about the connection 120 (eg a scart cable or similar) and on the display 110 visualized in overlay mode.

The operation of the set-top box 108 The user preferably performs this by pressing the function keys or a joystick of the remote control 112 whose commands (signals) over the connection 119 to the set-top box 108 be transmitted. The transmission of commands (signals) from the remote control 112 to the set-top box 108 is preferably wirelessly, for example via an infrared or Bluetooth connection or similar realized.

The TV station 104 generates the television signal 202 (Picture and sound, incl. Additional information). This is from the TV station 104 about the connection 118 to the receiving device 108 (Set-top box) of the user.

In parallel, the central server generates 102 the operator a data signal 204 which contains the relevant information 206 for the receiving device 108 contains at the user. The data signal 204 with the relevant information 206 becomes a set-top box 108 the user via an XML feed over the Internet. In the set-top box 108 it is processed by the appropriate function blocks.

The relevant information 206 for a content-synchronous display of hyperlinks to the TV program 210 on the display 110 if possible with sufficient lead time from the central server 102 to the set-top box 108 transmitted by the user. The set-top box 108 loads the Internet page belonging to the first URL into a memory in order to be able to superimpose it with the television picture at the specified time.

The Internet page associated with the first URL 210 is preferably in the central server 102 saved. But you can also use the TV channel 104 or stored anywhere on the Internet.

The corresponding function module in the set-top box 108 evaluates the information contained in the XML feeds, for example in the described TVEED format, with the first URLs of the accompanying Internet pages 208 and loads (automatically or optionally) the internet pages belonging to the current program of the TV channel selected by the TV viewer 208 into your own memory, even if the viewer does not show it.

If more space is available, more websites 208 according to the in the XML feed, for example in the described TVEED format, named URLs for other TV stations loaded.

The "first URL" that the server has in the data signal 204 transfers, referring merely to a website 208 on which the "second URLs" of the pages to be overlaid are stored. On this website 208 becomes a designated defined area 210 (Button, hyperlink) generated. This area 210 is linked to the second URL's of other internet sites that are accessible via the internet 116 for more information, eg. B. to an advertised product 208 to lead.

The website 208 will be in the set-top box 108 of the user prepared for presentation in overlay mode. At the specified time, when content in sync with the TV program accompanying information is to be offered, the television signal 202 and the prepared overlay presentation of the website 208 in the assembly 212 the set-top box 108 for the common transmission to the display 110 superimposed over the user and over the connection 120 to the display 110 of the user.

While a particular commercial is being broadcast, the display will show 110 transparent (overlay mode) the defined area 210 the website 208 , The defined area 210 can, for example, be displayed as a button, icon, link, graphic symbol, text, string, button or similar on the display 110 be shown. This link 210 Refers to a website that provides additional information about a product advertised in the commercial via a second URL 214 (eg a car).

The links 210 is by the user with the remote 112 clicked. As soon as suitable buttons or other controls on the remote control 112 be moved appears on the display 110 a cursor 216 , Selecting the link 210 is realized by the cursor 216 with the help of the remote control 112 to the overlay representation of the link 210 guided and the link 210 by pressing a predefined function key (eg "Enter") or by a joystick of the remote control 112 is clicked. When the TV program is running, the cursor is 216 hidden.

Of the User chooses such an accompanying offer to the current TV program from the Internet. At the same time with the call of the URL starts the recording of the further linear TV program for later delayed return into the linear TV program. If the selected program is already recorded If only the storage of the reentry point takes place. After the end of the display of the selected accompanying offer takes place the time-delayed re-entry into the current TV program from the Time from which the presentation of the TV show is interrupted and was replaced by the presentation of the Internet pages.

The linear TV program, all information contained in this program in the XML feed, for example in the described TVEED format, and all other information contained in the television signal are stored until the end of the use of the selected accompanying offer, ie image, sound and data which are transmitted concomitantly, in particular the data for interactive control of the respective program and other accompanying information transmitted in the blanking interval of an analog signal or as part of a multiplexed digital data stream.

The Record all Information allows it that the television viewer the original linear TV program time-delayed to see further and based on the also stored Data can also again select an accompanying offer with this TV program was offered. Saving the accompanying information and the resulting possibility for delayed use also takes place when the TV program was recorded from the outset to it at a later date consider.
