Methods and apparatuses for detecting timestamp discontinuities and video resolution discontinuities within a packet stream and marking locations of the detected discontinuities within the packet stream are described. Prior to transmission of the packet stream, an electronic device may perform timestamp discontinuity detection by acquiring a sequence of packets to be transmitted, identifying a first timestamp associated with an earliest packet within the sequence of packets, identifying a second timestamp associated with a latest packet within the sequence of packets, determining a timestamp time difference between the first timestamp and the second timestamp, determining a maximum chunk time difference based on a data rate at which the sequence of packets were encoded and a data size of the encoded packets, and detecting that a timestamp discontinuity exists within the sequence of packets if the timestamp time difference is greater than the maximum chunk time difference.

The present disclosure relates to a method and an ad decision sever for determining personalized messages during a provisioning of digital content. The method comprises to provide a set of personalized messages candidates by executing a relevance algorithm, which matches message metadata and content metadata. The method continues with receiving calculated network costs for the set of personalized message candidates in order to determine a set of personalized messages, which are optimized with respect to the received network costs by applying a multivariate optimization algorithm.

Systems and methods are described herein for streaming during unavailability of a content server. Upon determining that there are conditions indicating buffering issues during delivery of a media asset, a server determines a first group of devices suitable for receiving the media asset from the server and sharing the media asset on a peer-to-peer network. Then, the server determines a second group of devices suitable for receiving the media asset on a peer-to-peer network from a first group device. The server then determines groupings within which to share and receive the media asset. Next, the server transmits instructions to the devices in the first group to maintain in buffer and share certain portions of the media asset with the second group devices within their grouping. Finally, the server updates information detailing the media asset portions the devices are maintaining in buffer and sharing.

A device, system, and method perform an automatic change over for transport streams. The method is performed at an output server. The method includes selecting a first transport stream. The method includes generating a first portion of an output based on the first transport stream. The method includes selecting a second transport stream. The method includes determining a frametime to synchronize first packets of the first transport stream to second packets of the second transport stream. The frametime is based on a start time of a content item included in the first transport stream and the second transport stream and a completed progression of the content item using the first transport stream. The method includes determining a location in the second transport stream based on the frametime. The method includes generating a second portion of the output based on the second transport stream starting at the location.

According to one embodiment, a server device is communicably connected to a plurality of video distribution systems each including a transmission device, a receiving device and an HDMI cable. The server device is configured to aggregate the plurality of elements of received first data, for each combination of the type of the receiving device and the type of the HDMI cable that is indicated by each element of the first data. The server device is configured to select a video format optimum for the video distribution system based on first data. The server device is configured to transmit second data to cause the optimum video format to be selected to the transmission device transmitting the particular first data.

State information indicating states of a plurality of imaging apparatuses 100-x used for generating a virtual viewpoint image is acquired. At least one image type is determined from a plurality of image types indicating display formats of displaying the states of the plurality of imaging apparatuses 100-x based on the state information. Based on the determined image type, the states of the plurality of imaging apparatuses 100-x are displayed.

The present technology relates to an information processing device, an information processing method, a program, and an information processing system capable of providing a user who views a free viewpoint moving image with better user experience.

An information processing device of the present technology includes: a transmission unit that transmits a moving image; and a control unit that controls the transmission unit to transmit a free viewpoint moving image or a real camera viewpoint moving image on the basis of a result of determination on whether or not the free viewpoint moving image has been successfully generated, the free viewpoint moving image being a moving image generated by using a plurality of camera moving images generated by imaging a subject by using a plurality of cameras and viewed from an arbitrary position and direction, the real camera viewpoint moving image being a moving image generated from a camera moving image generated by imaging the subject by using a camera and viewed from a position and direction of the camera. The present technology is applicable to a real-time volumetric system that transmits a free viewpoint moving image in real time.

In one embodiment, a method receives a first stream identifier for a video stream. The first stream identifier is received in a request from a client for the video stream. The method selects a virtual stream identifier for the first stream identifier where the virtual stream identifier is associated with a plurality of physical stream identifiers associated with a plurality of physical streams. A ranking of the plurality of physical stream identifiers is analyzed to select one of the physical stream identifiers. Then, the method outputs the one of the physical stream identifiers as the video stream to use in response to the request for the first stream identifier. The one of the physical stream identifiers is sent to the client to allow the client to request the respective physical stream.

A method, a device, an electronic device and a readable storage medium detect a fault of a live stream service. The method specifically includes: obtaining log data of a live stream service; performing statistics on the log data according to a plurality of dimensions to be detected, to obtain log statistics data in each of the plurality of dimensions; analyzing the log statistics data in each of the plurality of dimensions respectively to obtain an analysis result; determining whether a live link portion corresponding to the log statistics data in each of the plurality of dimensions has a fault, according to the analysis result.

A storage system and method for media-based fast-fail configuration are provided. In one embodiment, the storage system aggregates elapsed time spent handling errors in parts of a media frame read from the memory of the storage system. The storage system compares the aggregated elapsed time to a threshold representing a total acceptable latency. If the aggregated elapsed time does not exceed the threshold, the storage system handles error(s) in other part(s) of the media frame read from the memory. However, if the aggregated elapsed time exceeds the threshold, the storage system sends an error to a host without handling error(s) in other part(s) of the media frame read from the memory. Other embodiments are provided.
