Description

METHOD AND PROCESSING UNIT FOR PROCESSING A VIDEO TRANSPORT
STREAM
FIELD OF THE INVENTION
The invention relates to a method and processing unit for processing a video transport stream.
BACKGROUND OF THE INVENTION
Modern video processing units incorporate many technologies and methods for providing high quality video to viewers. The video may come from broadcast or be stored in an optical disc, such as BD (Blu-ray Disc), HD-DVD (High Definition-Digital
Versatile Disc). The video can be 3D (three-dimensional) format or 2D format. The technologies and methods can be Cathode Ray Tubes (CRT), Liquid Crystal Displays (LCD), Lasers, or so-called Digital Micromirror Devices (DMD).
Most technologies and methods for providing high quality video are designed to enable a viewer watching video programs and being located at different positions around a display to experience watching stereoscopic video.
However, depending on these conventional technologies and methods to watch a video, a viewer has to wear special glasses using polarization or light shutters to filter out some unwanted video signal while enabling one respective video signal corresponding to the viewer's position to pass to the viewer's eyes. However, such technologies have some limitations since they do not provide a comfortable environment for the viewers.
OBJECT AND SUMMARY OF THE INVENTION
It is an object of the invention to provide an improved method and processing unit for processing a video transport stream.
The method according to the invention aims at processing a video transport stream comprising a set of metadata, and the metadata each comprise a video signal and viewing position parameters. The viewing position parameters indicating the relative position between a viewer and a video display which is intended to present the video signals. The method comprises the steps of:
- receiving viewing position information of the viewer,
- selecting in said transport stream the metadata that have viewing position parameters corresponding to said viewing position information, and
- outputting to the video display the video signal comprised in the selected metadata.
The invention also proposes a processing unit for implementing the different steps of said method according to the invention.
The advantage is that the proposed method and processing unit can dynamically select different video signals according to different viewing position information of the viewer, in order to present to the viewer the most suitable video according to his position compared to the display. In other words, it makes the video signal that is displayed adaptive to the viewer's position.
BRIEF DESCRIPTION OF THE DRAWINGS These and other aspects of the method and processing unit for processing a video transport stream according to the invention will become apparent from and will be elucidated with respect to the implementations and embodiments described hereinafter and with reference to the accompanying drawings, wherein:
Fig. 1 is a schematic diagram illustrating a system for displaying a video signal to a viewer who is positioned at different viewing positions around a display;
Fig. 2 is a schematic block diagram illustrating a processing unit for processing video transport stream according to the invention;
Fig. 3 is a schematic diagram illustrating a structure of a clip of AV streams; Fig. 4 is a flow chart diagram illustrating a method of processing a video transport stream according to the invention. Same reference numerals are used to denote similar parts throughout the figures.
DETAILED DESCRIPTION OF THE INVENTION Fig. 1 is a schematic diagram illustrating a system for displaying a video signal to a viewer who is located at different viewing positions around a display 100. A processing unit 200 is used to receive viewing position information of a viewer, and outputting to the display 100 a video signal that corresponds to the viewing position information. The display 100 is used to present the video signal to the viewer. The viewing position corresponds to the position of the viewer located around the display 100, e.g. the viewer can be located in viewing position 1, or viewing position 2, or viewing position 3 to watch the content of a video signal.
The viewing position information indicating the relative position between the viewer and the display 100 may correspond to viewing angles, such as angles al, a2 or a3. The viewing position information indicating the relative position between the viewer and the display 100 may correspond to viewing distances, such as distances dl, d2 or d3.
The processing unit 200 may be integrated in a player for optical discs (e.g. computer disc drive, standalone apparatus...) or digital TV STB. The display 100 may correspond, for example, to a TV or a computer display.
Fig. 2 is a schematic block diagram illustrating a processing unit 200 for processing a video transport stream according to the invention. The video transport stream comprises a set of metadata, and the metadata each comprise a video signal and viewing position parameters. The viewing position parameters indicate the relative position between a viewer and a video display intended to present the video signals. The viewing position parameters can correspond to viewing angles or viewing distances, as previously described. The viewing position parameters can be pre-stored in a data structure, and indicates the position of a viewer relative to the display in order to best watch the content of the corresponding video signal. The processing unit (200) comprises means for: - receiving (210) viewing position information of the viewer. The receiving means (210) may correspond to a buffer. The viewing position information can be detected by a number of sensors, a camera, or input directly by the viewer using a remote control, keyboard (not shown). - selecting (220) in said transport stream the metadata that have viewing position parameters that correspond to said viewing position information. The selecting means (220) may comprise means for comparing the viewing position information with the viewing position parameters, and means for choosing the metadata that have viewing position parameters closest to said viewing position information.
- outputting (230) to the video display the video signal included in the selected metadata.
For example, when the viewer moves from the viewing position 1 to the viewing position 2 (as shown in Fig. 1), the receiving means (210) will receive viewing position information corresponding to the viewing position 2 from the sensors, camera, remote control, or keyboard.
If the viewing position information is expressed by angle a2, the selecting means (220) will select the metadata in the video transport stream that have position parameters which are closest to the angle a2.
If the viewing position information is expressed by distance d2, the selecting means (220) will select the metadata in the video transport stream that have position parameters which are closest to the angle d2.
If the video transport stream is multiplexed, the processing unit 200 may comprise a de-multiplexer for de-multiplexing the video transport stream. If the video transport stream is encoded, the processing unit 200 may also comprise a decoder for decoding the video signal before outputting the video signal. For example, if the video transport stream is encoded according to the MPEG standard, the decoder is an MPEG decoder.
The data structure containing the viewing position parameters of the metadata may be a PID (Program identifier) table, or a database referring to a PID table or ClipMark. Use of a PID table
PID table: the PID table can be provided together with a video transport stream (encoded or not encoded), or be provided as a separate file. The PID table is similar to Cliplnfo (Clip Information) file defined in the BD (Blu-ray Disc) A/V application format. The Cliplnfo file is used to specify attributes of the metadata, such as the time stamps of the access point in corresponding metadata. Two solutions may be provided for the PID table:
Solution 1: The PID table contains entry point (i.e. start mark of metadata), attribute information (e.g. time stamps, format, definition, connection with other metadata), and the viewing position parameters of the metadata: the processing unit 200 can select viewing position parameters in the PID table according to current viewing position information, such as viewing angle or viewing distance.
Solution 2: The PID table does not contain viewing position parameters of the metadata; the PID table may comprise entry point, the attribute information, and metadata name used as a reference. As shown in Table 1 below, the metadata name [angle_id] is used as a reference (in bold in Table 1), so that the processing unit 200 can select a video signal according to current viewing position information of the viewer, such as viewing angle (or viewing distance).

Table 1
Use of ClipMark
Fig. 3 is a schematic diagram illustrating a structure of a clip AV stream. The viewing position parameters of the metadata can be pre-defined in a ClipMark. The ClipMark is defined in Blu-ray Disc Application format, and pre-defined between two adjacent metadata for storing entry point (start mark of metadata) and attribute information of metadata. In this example of the invention, the ClipMark is further used to contain the viewing position parameters of the metadata. Fig. 4 is a flow chart illustrating a method of processing a video transport stream according to the invention. The video transport stream comprises a set of metadata, and the metadata each comprise a video signal and viewing position parameters as described in Fig.2. The method comprises the steps of:
- receiving (410) viewing position information of the viewer.
- selecting (420) in said transport stream the metadata that have viewing position parameters corresponding to said viewing position information. The selecting (420) is intended to compare said viewing position information with said viewing position parameters and choose the metadata that have viewing position parameters closest to said viewing position information.
- outputting (430) to said video display the video signal comprised in the selected metadata.
It should be noted that the above-mentioned embodiments illustrate rather than limit the invention and that those skilled in the art will be able to design alternative embodiments without departing from the scope of the appended claims. In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim. The word 'comprising' does not exclude the presence of elements or steps not listed in a claim. The word "a" or "an" preceding an element does not exclude the presence of a plurality of such elements. The invention can be implemented by means of hardware comprising several distinct elements and by means of a suitably programmed computer. In the means claims enumerating several means, several of these means can be embodied by one and the same item of hardware. The usage of the words first, second and third, etcetera does not indicate any ordering. These words are to be interpreted as names.
