Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. A dynamic MPD can be supplemented by offline descriptor information transmitted OTA at display time so that the descriptor information, e.g., language information, captioning information, and the like, can be immediately presented on a UI.

A display apparatus and method. A display apparatus including a display control unit configured to display a moving image on a first region of a display screen; and a thumbnail generation unit configured to generate a plurality of thumbnail images based on a plurality of still images related to the moving image, wherein the display control unit is configured to display the plurality of thumbnail images on a second region of the display screen.

The invention relates to a method for providing a description of a program to a user equipment, comprising: receiving a set of text fields associated with the program; selecting a subset of text fields from the set of text fields based on a profile of a user and/or a profile of the user equipment; ordering the selected subset of text fields based on the profile of a user and/or the profile of the user equipment; editing the description of the program based on the ordered subset of text fields; and providing the description of the program to the user equipment.

The most active part of a video frame is magnified on a display to accommodate people with eye maladies such as glaucoma or perhaps retinitis pigmentosa. An area of interest in a video frame is identified, and that area is expanded or magnified to the center of the display, where people suffering from loss of peripheral vision can best see. Assuming the viewer sits a benchmark distance from the display, the active part of the image is expanded to fit in what can be seen in the center of the display without moving the head left to right and up and down. This may be done by the display recognizing where most of the action is taking place by means of with motion vectors and I-macroblocks, or by allowing the viewer to switch to various predetermined blocks on screen using a remote control.

The present document relates to transcoding of metadata, and in particular to a method and system for transcoding metadata with reduced computational complexity. A transcoder configured to transcode an inbound bitstream comprising an inbound content frame and an associated inbound metadata frame into an outbound bitstream comprising an outbound content frame and an associated outbound metadata frame is described. The inbound content frame is indicative of a signal encoded according to a first codec system and the outbound content frame is indicative of the signal encoded according to a second codec system. The transcoder is configured to identify an inbound block of metadata from the inbound metadata frame, the inbound block of metadata associated with an inbound descriptor indicative of one or more properties of metadata comprised within the inbound block of metadata, and to generate the outbound metadata frame from the inbound metadata frame based on the inbound descriptor.

A method for adapting the display of a video stream by a client includes a modification of a video tag of the client. The modified video tag is a function of a resolution of equipment supplying the video stream, of a size of a display window for the video stream, and of an accuracy parameter. The modified video tag has the same relation as the resolution to the size of the display window in which the video stream is displayed by the client.

A mobile device includes a display, at least one sensor, and a wireless transceiver. The mobile device also includes control circuitry coupled to the display, the at least one sensor, and the wireless transceiver. The control circuitry is configured to obtain content primitives from the at least one sensor, to perform content provisioning operations to obtain content based at least in part on the content primitives, and to display the obtained content on the display, wherein at least some of the content is virtual content. In response to a bandwidth condition of the wireless communication channel being less than a threshold, the control circuitry is configured to perform adjusted content provisioning operations that involve increasing an amount of image processing operations performed by the mobile device to obtain the content.

Techniques for dynamic digital advertising are disclosed. In one particular embodiment, the techniques may be realized as a dynamic advertising method comprising: receiving, by a computer processor associated with a dynamic advertising device, from a client device, first advertising content information including timepoint data for a playback event associated with first advertising content of a first advertising slot on a webpage; configuring, by the computer processor, a recall request for the first advertising content, the recall request including identification data associated with the first advertising content and specifying a timepoint obtained from the timepoint data; receiving, by the computer processor, from the client device, first advertising content resume request; and requesting, by the computer processor, for the client device, using the recall request, timepoint-configured first advertising content having a playback start time equal to the timepoint.

A display apparatus and method. A display apparatus including a display control unit configured to display a moving image on a first region of a display screen; and a thumbnail generation unit configured to generate a plurality of thumbnail images based on a plurality of still images related to the moving image, wherein the display control unit is configured to display the plurality of thumbnail images on a second region of the display screen.

An object is to make it possible to perform caption display satisfactorily in a case where the caption display position is designated as a relative position.

The video stream is decoded to obtain video data, and the subtitle stream including the caption information is decoded to obtain bitmap data of the caption. The caption display position in the caption display position information included in the caption information is designated as a relative position with respect to the caption display range. In a case where the aspect ratio of the video area is different from the aspect ratio of the display video area, the caption display position is determined with the display video area defined as the caption display range, further resize processing is performed, and the display position control is performed onto the bitmap data of the caption on the basis of the caption display position that has undergone the resize processing. Bitmap data of the caption that has undergone display position control is superimposed on the video data to obtain display video data.
