It is an object to realize high dynamic range rendering of a partial region of interest (ROI) segmented from a captured image. A transmitting apparatus includes a controlling section that controls the acquisition of high dynamic range information as information for use in the high dynamic range rendering of image data of a ROI (Region of interest), and a transmitting section that sends out the image data of the ROI as payload data and sends out ROI information as embedded data.

A method of decoding an enhanced video stream composed of base layer video access units and enhancement layer video access units, each access unit comprising a plurality of syntax structures, includes passing the syntax structures of the base layer access units to a base layer buffer, passing syntax structures of the enhancement layer access units to an enhancement layer buffer, outputting the syntax structures passed to the base layer buffer in a predetermined sequence, outputting the syntax structures passed to the enhancement layer buffer in a predetermined sequence, and recombining the sequences of syntax structures output by the base layer buffer and the enhancement layer buffer respectively to form a complete enhanced access unit, composed of base layer syntax structures and enhancement layer syntax structures in a predetermined sequence.

A video stream is obtained that includes at least one video stream image. The video stream is to be sent to one or more subscribers. Based on the obtaining the video stream, non-pixel data is retrieved. A first critical object in the video stream is determined. The determination is based on the obtaining the video stream and further based on the non-pixel data. The first critical object is represented by a first plurality of pixels. The first plurality of pixels is located within the at least one video stream image. A first prioritization of one or more network packets of the video stream is generated. The one or more network packets contain the first plurality of pixels. The first prioritization is generated based on determining the first critical object in the video stream.

A method and video decoder system using the method are provided for identifying video frames in an encoded or encrypted video stream without performing decoding or decryption. The method includes: receiving a video data stream comprised of a plurality of transport stream (TS) packets; detecting a first video frame in the video data stream, wherein detection of the first video frame includes registering a last checked position at the start of the video data stream, examining bytes in a next TS packet to identify a predetermined pattern indicating a network abstraction layer (NAL) unit, repeating the examining step until two TS packets have been identified that include an NAL unit, wherein the last checked position is updated after each examining step, and identifying a video frame based on a position of the NAL unit identified in the two TS packets; and repeating the detecting step for a plurality of additional video frames in the video data stream.

Systems and methods for efficiently determining that a media asset scheduled to be stored from one content source has been rescheduled to another content source. For example, by examining the contents of data packets received with a media asset which identify the media asset currently being received (e.g., a field in an event information table), a media guidance application executed on a set-top box or other user equipment device may determine in real-time that the media asset scheduled to be stored is not currently being transmitted from the originally-scheduled content source. In response to determining the media asset is not available from the originally-scheduled content source, the media guidance application may search through packets received from other content sources to determine a content source the media asset has been rescheduled to and store the media asset from that content source.

A receiver is disclosed. The present receiver comprises: a reception unit for receiving, through a channel, a frame in which an LLS for each broadcast service is included in different PLPs; and a signal processing unit for calculating the size of a memory required to time-deinterleave the PLPs including the LLS, and for processing the PLPs including the LLS, on the basis of the calculated size of the memory.

To enable satisfactory decoding processing corresponding to a decoding capability on a reception side.

Image data of pictures constituting moving image data are sorted into multiple hierarchies, image data of pictures of each of the sorted hierarchies are encoded, and video data including the encoded image data of the pictures of each of the hierarchies is generated. A container of a predetermined format including the video data is transmitted. The multiple hierarchies are divided into a predetermined number of hierarchy groups, the predetermined number being two or more, and identification information for identifying a hierarchy group to which encoded image data of each picture included in the video data belongs is inserted into a packet as a container of the video data.

A gateway device and system and method for use of the same are disclosed. In one embodiment, multiple wireless transceivers are located within a housing, which also interconnectively includes a processor and memory. To improve convenience, the gateway device may establish a pairing with a proximate wireless-enabled interactive programmable device having a display. Virtual remote control functionality for various amenities may then be provided. To improve safety, the gateway device may be incorporated into a geolocation and safety network.

A geolocationing system and method for providing awareness in a multi-space environment, such as a hospitality environment or educational environment, are presented. In one embodiment of the geolocationing system, a vertical and horizontal array of gateway devices is provided. Each gateway device includes a gateway device identification providing an accurately-known fixed location within the multi-space environment. Each gateway device includes a wireless transceiver that receives a beacon signal from a proximate wireless-enabled personal locator device. The gateway devices, in turn, send gateway signals to a server, which determines estimated location of the wireless-enabled personal locator device.

A method for transmitting media data in a Moving Picture Experts Group (MPEG) Media Transport (MMT) system is provided. The method includes receiving a Media Processing Unit (MPU) fragmented into one or more Media Fragment Units (MFUs), generating one or more multimedia data packets each including a packet header and a payload, based on the MPU, and transmitting the one or more multimedia data packets to a terminal. A payload header included in the payload includes identification information indicating an MPU to which at least one MPU included in the payload belongs, and a counter indicating the number of the at least one MPU.
