Description

METHOD FOR DISPLAYING CONTENT QN A MULTIMEDIA PLAYER AND A MULTIMEDIA PLAYER
Technical field
The present disclosure relates to a method for displaying content on a multimedia player, the multimedia player receiving and displaying first content comprising video. The disclosure further relates to such a multimedia player.
Background
Such methods may be embodied in many different ways. The multimedia player may be a TV set, a mobile phone, a PDA, etc., and the content may be received by from a server on the Internet, from a DVD player, or traditionally via broadcasting.
One problem associated with such displaying methods is how to allow the user to access additional information relating to objects of different kinds appearing in the video content. This may be done, as is common with DVD movies, by including so called bonus content on the DVD providing more in- formation about items appearing in the video content. In broadcasting situations, it is common to provide additional information separately by referring the user to a website run by the broadcasting company.
Summary One object of the present disclosure is to provide a more direct and accurate method of displaying additional information to the user on demand. This object is achieved by means of a displaying method according to claim 1 or by means of a multimedia player according to claim 7.
More specifically, this object is achieved with a method of the initially mentioned kind where the multimedia player additionally receives second content comprising information related to objects in the first content, obtains a user input comprising a position indication related to the first content currently displayed, extracts object information from the second content based on the position indication, and emits extracted information to a user. This allows the user to quickly and readily extract additional information relating to an object displayed in the first content.
The second content may comprise a lookup table where positions in a current video frame of the first content are linked to information relating to objects, such that inputting of said position indication to the lookup table results in the retrieval of said object information.
Each position of a first object in a current video frame may be linked to object information relating to the first object. Additionally, positions in the vicinity of the first object in the current video frame may be linked to the object information relating to the first object in order to facilitate the selection of an object in an image.
Further, positions occupied by the first object in a previous video frame may linked to the object information relating to the first object. This facilitates the selection of fast moving objects.
It may be possible to allow the user to contribute to the second content by allowing the user to update the second content, and sending the updated content to the source of the second content.
The object is further achieved by a multimedia player comprising a first receiver and means for displaying first content comprising video, wherein the multimedia player has a second receiver for receiving second content comprising information related to objects in the first content, an input device for obtaining a user input comprising a position indication related to the first content currently displayed, means for extracting information from the second content based on the position indication, and means for emitting extracted information to a user. Such a player provides advantages corresponding to those of the above-mentioned method.
The multimedia player may be e.g. a portable device, such as a mobile phone or a PDA, an optical storage media player, such as a DVD or Blueray player, or a personal computer, PC.
Brief description of the drawings
Fig 1 illustrates schematically a general overview of a system.
Figs 2-4 illustrate use of the disclosed method.
Detailed description
Fig 1 illustrates schematically a general overview of a system. A multimedia player 1 , MMP, is used to provide content to a user, and is connected to a display 3 and an input device 5. The display 3 and the input device 5 may be integrated with the MMP
1 , which may the typically be a cell phone, a PDA (Personal Digital Assistant), or a portable media player. The MMP 1 may however also be a DVD- or Blueray player or the like. Additionally, the MMP may be a set-top box, a PC or a TV set.
The MMP 1 receives content comprising video in a first stream 7, typically containing MPEG data, from a first source 9, in the illustrated case a server (Server A). The first source 9 may however be a different system depending on the application. For instance, if the MMP is a DVD player, the first source will be the DVD in the player, and if the MMP is a TV-set or a set- top box, the first source may be a broadcasting system, etc.
The video content received in the first stream 7 contains objects of different kinds, and the user may wish to receive additional information relating to objects in the content shown by the MMP. By objects is here not only meant tangible objects, such as cars, houses, etc., but also more abstract items such as words, trademarks etc. and thus anything that can be visually displayed may be regarded as an object in this sense. Such additional information, that a user may desire to retrieve, may be provided in a second stream 11 which is a secondary stream that may come from the first source or a second source 13, e.g. as illustrated Server B, different from the source of the first stream. Needless to say, more than one secondary stream may be provided. In general, the MMP 1 is arranged for receiving second content, comprising information related to objects in the first content. This content may be displayed to the user if the user so desires. If the user desires to receive additional information relating to a displayed object he generates a user input that reflects his intention. The user input comprises a position indication related to the first content currently displayed. Based on this position indication, information is extracted from the second content as will be described later, and the extracted information is emitted to the user. Figs 2-4 illustrate use of the disclosed method. In fig 2 there is illustrated a display 3 that currently displays a video content including a number of objects 15, 17. In a typical scenario, the video content may be a movie, which makes use of so-called product placement, i.e. the movie involves a number of products that are being advertised as a source for financing the movie. In fig 2, a car 15 and a crescent 17 are currently displayed. In the illustrated case, the. user is capable of moving a mouse pointer 19 and to click on different objects to generate position indications. The user marks the car 15 by clicking on it and thus generates a position x, y indication at a specific time point T in the movie. Based on this information, the MMP may now retrieve information relating to the car 15 from the second information stream.
The position indication can be generated using conventional position indication device, such as a mouse or joystick. It should however be noted that the position information can be generated in other ways as long as a point or an area in an image can be indicated. For instance, if the MMP is a portable device such as a cell phone the keypad can be used. If e.g. the keypad is arranged with the digits 1-9 arranged in three rows {(1 ,2,3); (4,5,6);(7,8,9)}, each key may correspond to one ninth of the display, and pressing "3" may correspond to marking the area in the upper right corner.
A touch screen display works as another suitable example of an input device, where the user simply touches the area of the display where the object of interest is currently displayed in order to generate a position indication. Fig 3 illustrates a case where a lookup table 21 is used to retrieve the information. The lookup table 21 may comprise information relating to in which positions and at which points of time a specific object is displayed in the movie. Thus, by inputting to the lookup table the generated timing and position information T, x, y, the system may receive an answer correlated to the object, in this case the text "AUTO 3000" which may be the model of the displayed car 15 in fig 2. Note that not all objects in a video content may be described by means of additional information in the second information stream. For instance, had the user clicked instead on the crescent 17 in fig 2, the corresponding position and timing information may have had resulted in an empty answer from the lookup table. An area, i.e. a range of positions, may also be inputted to the lookup table.
It may be the case that the object in question is small or moves quickly over the display, and in this case it may be difficult for the user to mark the object such that position information is generated that exactly matches the position of the object in the relevant video frame. This may be solved by letting the positions corresponding to the object in the lookup table extend into an area around the positions where the object is actually displayed. If the objects moves quickly it may be advantageous to take into account the object's position also in one or more preceding video frame. Even if in fig 3 both time and position is fed to the lookup table, a position or a range of positions may be sufficient. The lookup table may be received by the MMP as an information stream that is synchronized with respect to the first information stream, and in that case timing information is of course superfluous. There may thus, as illustrated by the dotted arrows of fig 1 be a communication of synchronization information between the sources of information 9, 13 for the first and second content streams. In fig 4 it is illustrated how the retrieved information may be displayed to the user. In the illustrated case the retrieved text string is displayed as included in the video content.
There are of course other conceivable ways of emitting the retrieved information to the user. Typically, in a product placement context, the information received as a response to the provided position information may be a URL. If the MMP is a personal computer or the like, a separate browser window may for instance be opened with the URL, such that the user may for instance purchase a product which he has clicked on.
It is also possible to provide the retrieved information to the user as audible information. Further, additional video content, e.g. a commercial related to a product clicked on, may be shown. This may be done either on a sub-part of the display while simultaneously showing the video content of the first stream. Alternatively the displaying of the first stream may be temporarily stopped while displaying the commercial on a full screen. Returning to fig 1, the MMP comprises a first receiver 25 to receive the first content, and a second receiver 27 to receive the second content. Additionally, the MMP comprises means 29, typically software implemented, for extracting information from the second content based on the position indication, and means for emitting 31 extracted information to a user. The emitting means 31 may include a display, but, for instance in the case of a set-top box, the emitting means will instead be video signal generation means, producing a video signal that is sent to a display.
The MMP may additionally allow the user to edit or make contributions to the second content, and these contributions may be uploaded to the second source 13, by means of a transmitter 33 in the MMP. The user may thus be allowed to alter the supplemental information in the second stream much in the same way as is done in connection with a so-called wiki. It is further possible for the user to create a third content which is a duplicate of the second content with additional contributions made by the user. This third content may be uploaded e.g. to a third server (not shown).
It should be noted that the functional blocks in the MMP of fig 1 may be obtained in many different ways using, software, hardware and combinations thereof. Additionally some of the functional blocks may be combined with each other in different ways.
The invention is not restricted to the disclosed embodiments and may be varied and altered within the scope of the appended claims.
