IMAGE DISPLAY APPARATUS AND IMAGE DISPLAYING METHOD
An image display apparatus and an image displaying method are provided. The image display apparatus includes a display; and a processor configured to parse information about a channel selected in response to a channel selection signal, determine whether to provide a plurality of services through the selected channel based on the parsed information, and, in response to the determining that the plurality of services are to be provided through the selected channel, obtain a plurality of service streams respectively corresponding to the plurality of services provided through the selected channel; and a decoder configured to decode one service stream from among the obtained plurality of service streams.
LOW LATENCY WIRELESS VIRTUAL REALITY SYSTEMS AND METHODS
Virtual Reality (VR) systems, apparatuses and methods of processing data are provided which include predicting, at a server, a user viewpoint of a next frame of video data based on received user feedback information sensed at a client, rendering a portion of the next frame using the prediction, encoding the portion, formatting the encoded portion into packets and transmitting the video data. At a client, the encoded and packetized A/V data is received and depacketized. The portion of video data and corresponding audio data is decoded and controlled to be displayed and aurally provided in synchronization. Latency may be minimized by utilizing handshaking between hardware components and/or software components such as a 3D server engine, one or more client processors, one or more client processors, a video encoder, a server NIC, a video decoder, a client NIC; and a 3D client engine.
SYSTEM AND METHOD FOR FLEXIBLE VIDEO CONSTRUCTION
System and method for flexible video construction, particularly of a personalized video clip which provides instructions to a viewer with regard to health and wellness. An ordered list of video input files is chained together, to create a single output video file using a chosen container. Timestamp values are tracked, to ensure synchronization of multiple joined clips, optionally using adjustments of the audio channel or the video channel. A video construction server utilizes information from multiple sources, to construct the video clip.
Method and apparatus for transmitting media data in multimedia transport system
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 MFU included in the payload belongs, and a counter indicating the number of the at least one MFU.
Video channel change system
A video channel change system may include one or more processors and a memory. The one or more processors may receive first packets including first video frames associated with a first video channel and second packets including second video frames associated with a second video channel. The one or more processors may decode the first packets and display the first video frames while buffering, in a buffer, the second packets. The one or more processors may determine that a packet of the second packets includes a random access point without decoding the packet, discard the second packets from the buffer that were received prior to the packet, buffer additional second packets received subsequent to the packet, and decode the second packets stored in the buffer and display the second video frames included therein, in response to a request to change from the first video channel to the second video channel.
Method for efficient processing of BTP enabled MPEG4 stream
A system is provided for providing a trickplay operation using a digital video recorder (DVR) when the video includes Broadcom Transport Packets (BTPs) designed for MPEG-2, but in an MPEG-4 video steam. In a first embodiment, to enable trickplay to function properly with MPEG-4 video, the BTP descriptors included with each group of data frames are disabled so that a single descriptor provided without BTPs that would otherwise be provided in MPEG-4 is all that remains. In a second embodiment, the 5 descriptors for MPEG-4 are combined into a single descriptor. In a third embodiment, the pace of decoding of the MPEG-4 descriptors is increased so that the speed of encoding all the 5 descriptors is comparable to the pace of decoding a single MPEG-2 descriptor.
Packetized content stream-enabled headphone system
Novel techniques are described for enabling headphone-driven systems to handle packetized streams of next-generation television (NGTV) content. For example, a headphone system can include an antenna and a NGTV tuner to receive and decode a packetized television content stream wirelessly from a content provider via a digital television content network. The decoded stream can be processed by the headphone system to generate an audio stream and a video stream. Audio content of the audio stream can be output via an audio transducer of the headphone system. The video stream can be transmitted, via a device interface of the headphone system, to a media playback device for outputting of video content (e.g., and audio content, in some cases) of the video stream. For example, the video stream is transmitted, via a short-range wireless network to a smartphone, tablet computer, transport vehicle display, or other playback device.
Systems and methods for adapting content items to secured endpoint media device data
Methods, systems, and machine-readable media for adapting content composites to device operations of an endpoint media device are disclosed. Blockchain data associated with a blockchain address may be processed by one or more processing devices. The blockchain data and/or the blockchain address may be mapped by the one or more processing devices to a first endpoint media device. Based at least in part on the blockchain data, a first content composite may be identified by one or more processing devices for delivery from a content provider system via one or more networks to the first endpoint media device. Transmission of the first content composite may be caused where, consequent to delivery of the first content composite to the first endpoint media device, the first endpoint media device or a second endpoint media device performs at least one operation relating to the first content composite.
Broadcast receiver and video data processing method thereof
A broadcast receiver and a method for processing video data are disclosed. The method for controlling a three dimensional (3D) video display output of a broadcast receiver includes receiving a broadcast signal including a video stream, wherein the video stream includes a plurality of video stream sections having different view points, acquiring view point information indicating corresponding view points of the video stream sections, and controlling a three dimensional (3D) video display output of the video stream according to the obtained view point information.
Using timed transport stream for receiver-side inter-device communication
Systems, methods, devices, and non-transitory media of the various embodiments facilitate real time playback of a digital broadcast by enabling reduction of the amount of time a receiver device's low power mode interface with a separate computing device operates in an operational/high power mode. The receiver device may associate a stream of media packets of a digital broadcast with system time clock timestamps indicating when the media packets were received, and store the media packets in a temporary packet buffer. Periodically, a media packet burst stored in the temporary packet buffer may be sent to the separate computing device via a low power mode interface operating in an operational/high-power mode different than a low power mode. The low power mode interface may be returned to the low-power mode until the next burst of packets is sent to the separate computing device.
