Aspects of the subject disclosure may include, for example, a method for providing redundancy in a video data stream. For every data frame of a plurality of data frames of video content, the method includes dividing the data frame into a plurality of data segments and copying a plurality of each of the plurality of data segments to the plurality of data frames in a data stream to provide redundancy for the data frame within the plurality of data frames in the data stream. The plurality of each of the plurality of data segments is distributed across the plurality of data frames to provide generate a plurality of redundancy-enhanced data frames that provide the redundancy over a protection interval associated with a network path. The method includes transmitting a data stream comprising the plurality of redundancy-enhanced data frames to a receiver via the network path. Other embodiments are disclosed.

There is provided a system including a non-transitory memory storing an executable code, and a hardware processor configured to execute the executable code to receive first and second Internet protocol (IP) video packets including respective first and second video content, and to identify a common reference time for the first and second IP video packets. The hardware processor also determines a first buffering interval for synchronizing the first and second IP video packets based on a first frame number, a first line number, and a first pixel number of the first video content, and the common reference time. In addition, the hardware processor holds the first IP video packet during the first buffering interval, and releases the first IP video packet when the first buffering interval elapses so as to align the first video content with the second video content at the common reference time.

A method of receiving a broadcast service is provided. The method includes receiving uncompressed audio or video content, obtaining information regarding a channel of the uncompressed audio or video content on the basis of a part of the uncompressed audio or video content, and obtaining content and trigger information for the broadcast service by using the obtained information.

Provided is an IP uncompressed video encoder that converts an IP packet stream of uncompressed video to an IP packet stream of compressed video. The invention is a video encoder that produces an IP packetized stream of compressed video from an IP packetized stream of an uncompressed video signal, comprising: receiving means packetizing, from a network, one or a plurality of IP packetized streams of an uncompressed video signal; retrieving means for retrieving video data from the one or plurality of IP packetized streams of the uncompressed video signal; compressing means for compressing the retrieved video data; and transmitting means configured to IP packetize video compressed by the compressing means to create and transmit a stream of compressed video.

A computer system receives a content-transition indication to provide a second decompressed media stream to a presentation device instead of providing a first decompressed media stream. In response to receiving the content-transition indication, the computer system ceases to receive a first compressed media stream corresponding to the first decompressed media stream and continues to provide the first decompressed media stream to the presentation device using first buffered data. The computer system selects a transition point for a second compressed media stream, corresponding to the second decompressed media stream, based on a quantity of data of the second compressed media stream to be buffered. While continuing to provide the first decompressed media stream to the presentation device using the first buffered data, the computer system receives and buffers the second compressed media stream starting at the transition point. The computer system provides the second decompressed media stream to the presentation device.

The present invention relates to a method and an apparatus for transmitting and receiving an ultra-high definition broadcasting signal for high dynamic range representation in a digital broadcasting system. An apparatus for receiving an ultra-high definition broadcasting signal according to an embodiment of the present invention comprises: a receiving unit for receiving the ultra-high definition broadcasting signal including ultra-high definition broadcasting contents and high dynamic range metadata, the high dynamic range metadata indicating brightness information represented in the ultra-high definition broadcasting contents and information on a method for converting the ultra-high definition broadcast contents to be adapted to a display environment of the receiving apparatus; a decoder for decoding the received ultra-high definition broadcasting contents; and a reproduction unit for reproducing the decoded ultra-high definition broadcasting contents.

A computer system generates a first decompressed media stream based on a first compressed media stream. While providing the first decompressed media stream to a presentation device, the computer system receives a content-transition indication for providing a second decompressed media stream to the presentation device instead of the first decompressed media stream. The content-transition indication corresponds to a request to display the second decompressed media stream starting at a respective point within a predefined portion of the second decompressed media stream. The computer system receives a second compressed media stream corresponding to the second decompressed media stream. In response to receiving the content-transition indication, the computer system generates the predefined portion of the second decompressed media stream and provides a subset of the predefined portion, that does not include content prior to the respective point, to the presentation device instead of the first decompressed media stream.

A method includes the following operations: (1) executing an application that that generates a series of video frames using a graphics processing unit (GPU); (2) determining that a first video frame in the series has been completely written to a back buffer; (3) determining whether a current scan line of a second video frame is outside of a specified region, where the second video frame is stored in a front buffer and is being read out line by line following receipt of a monitored synchronizing signal; (4) presenting the first video frame to the front buffer without frame transitions, if the current scan line is outside of the specified region and is in a vertical blanking interval (VBI); and (5) presenting the first video to the front buffer with frame transitions, if the current scan line is outside of the specified region and is not in the VBI.

The present disclosure is directed to systems and methods for provisioning live media services. For example, a method may include receiving, at a user equipment (UE), configuration data for the UE. The configuration data may be based on one or more parameters from among a plurality of different types of parameters and generated in response to a UE configuration update being initiated. The method may also include executing, at the UE, the configuration data to enable the UE to provision a live media production service.
