A stereoscopic display device including a barrier panel is provided. When a viewing distance of a viewer is out of the proper range, the stereoscopic display device may shift the blocking regions and the transmitting regions of the barrier panel. The stereoscopic display device may maintain the ratio of channels located within a barrier blocking region and a barrier transmitting region of the barrier panel by using the channels disposed within trigger regions of the barrier panel. Thus, the stereoscopic display device may provide a stereoscopic image of good quality to the viewer located at a region being out of the proper range.

A method of a transmission device in a multimedia system comprises the steps of: detecting a request for changing first-type data into second-type data while the first-type data is being played at a given point in time; and transmitting, before the second-type data is played, information necessary for replaying data, among the first-type data, played prior to the given point in time, and/or data, among the second-type data, played prior to the given point in time.

Device and method for transmitting and receiving signal in multimedia system

A light field display device including: a display panel including a plurality of subpixels each emitting a light field; and a lenticular lens array on the display panel and including a plurality of lenticular lenses, wherein the plurality of lenticular lenses correspond to a plurality of subpixel groups each including the plurality of subpixels, and wherein a width of each of the plurality of subpixel groups is greater than a width of each of the plurality of lenticular lenses.

Light field display device having improved viewing angle

A three dimensional (3D) display apparatus can include lenticular lenses between a display panel and a viewing angle control film. The display panel can have a curvature. The viewing angle control film can include a plurality of light-blocking patterns between a first control substrate and a second control substrate. A pitch and a height of the plurality of light-blocking patterns can be determined by a curvature radius of the lenticular lenses, a distance between the viewing angle control film and a set viewing region, and a length of the display panel corresponding to the set viewing region. Thus, in the 3D display apparatus, the quality of 3D images provided to a user can be improved.

3D display apparatus having lenticular lenses

A method for providing a broadcast service is provided. The method includes transmitting a user datagram protocol (UDP)/internet protocol (IP) packet including a first message, the first message containing information about a message to be signed and transmitted, and transmitting a moving picture experts group (MPEG) media transport protocol (MMTP) packet including a second message, the second message containing information about the broadcast service and information indicating whether the information about the broadcast service is signed. The first message includes an identifier of a key used to verify a signature of the message to be transmitted and signed and an identifier of a hash algorithm used to calculate a hash value of the message to be transmitted and signed.

Method and apparatus for providing broadcast service

Provided is a method for supporting an immersive media service by a media transmission device. The method comprises the steps of: determining at least one space among a plurality of spaces of interest (SOI) based on SOI description information; and transmitting, to a media reception apparatus, partial SOI description information among the SOI description information and partial immersive media data among immersive media data, wherein the partial SOI description and the partial immersive media data corresponds to the determined at least one SOI, wherein the partial SOI description information includes at least one of identification information for the at least one SOI, a space range indicator for an object of interest (OOI), a priority indicator for the OOI, or an object vector for the OOI.

Method and device for transmitting immersive media

A 3D display apparatus in which lenticular lenses are disposed on a display panel is provided. The display panel can include pixel regions arranged in a pen-tile shape. For example, the display panel can include a first column of pixel regions in which a first pixel region displaying a first color and a second pixel region displaying a second color are alternatively disposed in a first direction, and a second column of pixel regions in which a third pixel region displaying a third color is disposed, and the first column and the second column can be alternatively disposed in a second direction perpendicular to the first direction. Each of the lenticular lenses can extend in an inclined direction. Thus, in the 3D display apparatus, the rate of color reproduction can be improved in a pen-tile shape.

The present invention relates to a method and device for transmitting or receiving a broadcast service including a packet, which is generated using an application layer forward error correction (AL-FEC) scheme, in a multimedia service system. An embodiment of the present invention provides a method for transmitting a broadcast service by a transmitter, the method comprising the steps of: determining one forward error correction (FEC) scheme for a broadcast service among multiple FEC schemes; configuring a signaling message so as to include an identifier indicating the determined FEC scheme; and transmitting the configured signaling message.

Method and device for transmitting or receiving broadcast service in multimedia service system

A method for transmitting multimedia according to the present disclosure comprises: a step of transmitting a first message including fixed delay information and buffer information with respect to a receiving device; and a step of transmitting a packet relating to the multimedia and including a transmission time stamp, wherein a first packet is sent out from a digital buffer of the receiving device at a time determined by adding up the transmission time stamp and the fixed delay information.

Method and device for unicast-based multimedia service

A 3D display apparatus including lenticular lenses is provided. The lenticular lenses may be disposed between a display panel and a viewing angle control film. A direction in which the lenticular lenses extend may be inclined with a direction in which pixel regions of the display panel are arranged. The display panel may include light-blocking patterns overlapping with a boundary of the lenticular lenses. Thus, in the 3D display apparatus, the quality of the image provided to the user may be improved.

The present disclosure relates to a method and device for receiving a content by a terminal device. The method for receiving a content by a terminal device comprises the steps of: transmitting a query message requesting content-related information to a first server; receiving a response message including the content-related information from the first server; on the basis of the response message, requesting a content from a second server corresponding to the content-related information; and receiving the content from the second server, wherein the content-related information includes internet protocol (IP) addresses of the second server, pieces of port information, and pieces of media information relating to a content.

Multimedia service content providing device and method

A stereoscopic display device has a barrier panel. The barrier panel of the stereoscopic display device may include sequentially stacked first channel electrodes, second channel electrodes, and third channel electrodes. Each of the third channel electrodes may be disposed between the second channel electrodes. A distance between the third channel electrodes may be the same as a horizontal width of each third channel electrode. Each of the first channel electrodes may include a first region overlapping with an end portion of the second channel electrode, and a second region overlapping with an end portion of the third channel electrode facing the end portion of the second channel electrodes overlapping with the first region of adjacent first channel electrode.
