The present disclosure provides a data transmission method of a system in an IP based broadcasting network, the data transmission method comprising the steps of: generating an MPEG media transport protocol (MMTP) packet using a media processing unit (MPU) for a service; generating an IP packet using the MMTP packet; generating a layer 2 (L2) packet using the IP packet and generating a layer 1 (L1) packet stream using the L2 packet; and transmitting the L1 packet stream, wherein absolute time information of the system is included in one of a transmission frame of the L1 packet stream and the L2 packet.

A plurality of byte ranges forms a sample for content output from a player device, and includes at least one double-encrypted byte range. The plurality of byte ranges is stored in a secured memory, and the at least one double-encrypted byte range is partially decrypted to generate at least one decrypted singe-encrypted byte range. The plurality of byte ranges is stored in an unsecured memory using the at least one decrypted single-encrypted byte range in place of the at least one double-encrypted byte range.

There is provided is a transmitter including an image processor that sets region information corresponding to a region set for an image for each row in the image and that transmits the set region information and region data corresponding to the region for each row, in which the image processor sets the region by analyzing the image or on a basis of externally acquired region-designating information, and the region information includes information indicating a position of a row and information indicating a position of a column of the region included in the row.

Methods, systems, and media for synchronizing audio and video content on multiple media devices are provided. In some embodiments, the method comprises: receiving, at a media device, an indication of a media content item to be presented using the media device, wherein the media device includes an audio component for presenting audio content associated with the media content item and a video component for presenting video content associated with the media content item; determining that the media device is associated with a group of media devices for presenting the media content item, wherein the group of media devices includes the media device and at least one audio device that presents the audio content associated with the media content item; generating an audio timestamp that controls the presentation of the audio content on the group of media devices; generating a video timestamp that control the presentation of the video content on the group of media devices, wherein the video timestamp is based on the generated audio timestamp; and causing, at the media device, the video content associated with the media content item to be presented using the generated video timestamp and causing the audio content associated with the media content item to be simultaneously presented by the at least one audio device in the group of media devices by transmitting the audio timestamp to the at least one audio device in the group of media devices.

In various embodiments, a Data Processing System for Generating Interactive User Interfaces and Interactive Game Systems Based on Spatiotemporal Analysis of Video Content may be configured to: (1) enable a user to select one or more players participating in a substantially live (e.g., live) sporting or other event; (2) determine scoring data for each of the one or more selected players during the sporting or other event; (3) track the determined scoring data; (4) generate a custom (e.g., to the user) user interface that includes the scoring data; and (5) display the custom user interface over at least a portion of a display screen (e.g., on a mobile computing device) displaying one or more video feeds of the sporting or other event. In this way, the system may be configured to convert a video feed of a sporting event into an interactive game.

An object is to efficiently display pieces of image data of some regions of interest (ROI) cut from a captured image on a display device. A reception device includes: a reception unit that receives a transmission signal in which image data of a predetermined number of regions of interest (ROIs) cut from a predetermined captured image is included in payload data and ROI information corresponding to a predetermined number of the ROIs is included in embedded data; and a processing unit that is configured to perform restoration processing of restoring the image data of the ROI so as to be displayable on a predetermined display device on the basis of the ROI information extracted from the embedded data.

An encoding device evaluates a plurality of processing and/or post-processing algorithms and/or methods to be applied to a video stream, and signals a selected method, algorithm, class or category of methods/algorithms either in an encoded bitstream or as side information related to the encoded bitstream. A decoding device or post-processor utilizes the signaled algorithm or selects an algorithm/method based on the signaled method or algorithm. The selection is based, for example, on availability of the algorithm/method at the decoder/post-processor and/or cost of implementation. The video stream may comprise, for example, downsampled multiplexed stereoscopic images and the selected algorithm may include any of upconversion and/or error correction techniques that contribute to a restoration of the downsampled images.

A set-top box receives original video streams and generates a guide video stream that includes each of the original video streams resized and arranged as a plurality of scaled video streams such that all of the scaled video streams are simultaneously visible and playing on the guide video stream. The guide video stream is displayed on a display device and the set-top box provides an interactive user interface on the display device in conjunction with the guide video stream to allow a user of the set-top box to select one of the scaled video streams for full screen playback. In response to the user selecting a particular scaled video stream on the guide video stream for full screen playback, the set-top box plays full screen on the display device a particular original video stream corresponding to the particular scaled video stream as received via the communication interface.

Video content is uploaded via the Internet to a video-on-demand (VOD) server identified by a title and a hierarchical address of categories and subcategories for categorizing the title. The VOD server converts and stores the video content at a storage address in a video content database linked to the title. The title is listed in a location of an electronic program guide (EPG) using the same categories and subcategories as in its hierarchical address. Any TV subscriber can access the EPG and navigate through its categories and subcategories to find a title for viewing on the TV. This can enable many new blogging or podcasting-like programs by popular “Hosts” to be self-published on the Internet and readily navigated for display on TV. The EPG can also store TV program addresses as bookmarks and allow them to be shared with other subscribers or with friends and contacts online by sending to their email addresses.

A UHD display presents HD video in the native resolution of HD, leaving some portions of the UHD display unused for presenting the HD video. Ancillary information received, for example, in real time with the HD video or in parallel with the HD video over the Internet is presented in the unused portions of the UHD display along with the HD video.
