Methods, systems, and apparatuses for improved content scoring and delivery are described. A quality score for delivered content may be determined based on one or more output metrics. A first quality score may be provided to a content distribution network. The content distribution network may instruct the user device, or the user device may determine without receiving such an instruction, of methods/processes by which it may improve the one or more output metrics associated with output of the delivered content by adjusting one or more output parameters. The first quality score may also be used by the content distribution network to determine methods/processes by which network-related parameters and constraints may be managed in order to improve the quality of delivered content.

Methods, systems, and computer readable media may be operable to facilitate switching the video and audio output to a different service when a current service is not presentable. When outputting content from a first service, a multimedia device may identify and switch to an output of content from a second service when the content from the first service becomes unpresentable. The multimedia device may continue to monitor the quality or presentability of the content from the first service, and the multimedia device may switch from an output of content form the second service to an output of content from the first service when the determination is made that the content from the first service is presentable.

Aspects of the subject disclosure may include, for example, embodiments of a video adapter that can include transmitting a first probe video clip to a communication device over a communication network, detecting first probe information from the communication device over the communication network, and identifying a first group of network conditions based on the first probe information. Further embodiments can include obtaining video content from a video content server over the communication network, and delivering the video content to the communication device over the communication network according to the first group of network conditions. Other embodiments are disclosed.

Systems and methods described herein provide for rendering and quality monitoring of rendering of a 360-degree video, where the video has a plurality of representations with different levels of quality in different regions. In an exemplary method, a client device tracks a position of a viewport with respect to the 360-degree video and renders to the viewport a selected set of the representations. The client adaptively adds and removes representations from the selected set based on the viewport position. The client also measures and reports a viewport switching latency. In some embodiments, the latency for a viewport switch is a comparable-quality viewport switch latency that represents the time it takes after a viewport switch to return to a quality comparable to the pre-switch viewport quality.

A video packet stream is transmitted from a transmitting device to a receiving device over a network, by transmitting an audio packet stream to the receiving device, determining a measure of network bandwidth in dependence on one or more metrics associated with receiving the audio packet stream at the receiving device, and enabling a video packet stream in dependence on the determined measure.

An example electronic device according to various embodiments of this document may include: at least one auxiliary processor; and a main processor operably connected to the at least one auxiliary processor, wherein the main processor may be configured to: obtain moving image data; separate the moving image data into image data including plural consecutive image frames, first audio data including plural consecutive audio frames, and plural timestamps corresponding respectively to the plural consecutive audio frames; generate second audio data using the first audio data by adding header data to each of the plural audio frames; transmit the second audio data to the at least one auxiliary processor; generate, based on first time information successively received from the at least one auxiliary processor, second time information; and play back the image data based on the second time information, and wherein the at least one auxiliary processor may be configured to: play back an audio signal based on the received second audio data; and generate the first time information about a playback time of the audio signal based on the header data.

Disclosed are a signal processing device and an image display apparatus including the same. The signal processing device of an embodiment of the present disclosure includes: a quality calculator configured to calculate an source quality of an image signal received from an external settop box or a network; an image quality setter configured to set an image quality of the image signal based on the calculated source quality; and an image quality processor configured to perform image quality processing on the image signal based on the set image quality, wherein in response to the source quality of the received image signal being changed at a first time point, the image quality setter changes an image quality setting sequentially from a first setting to a second setting; and based on the image quality setting, the image quality processor performs image quality processing. Accordingly, flicker may be reduced when an image quality is changed due to a change in the source quality of the received image signal.

Disclosed are a delay control method, a delay control apparatus, a terminal device and a storage medium. The delay control method comprises: initializing a cached data amount, and setting an initial delay threshold value; acquiring real-time cached data of a client, and determining a network status of the client according to same; and adjusting the current delay threshold value according to the network status. According to the delay control method, a network status of a user end is determined according to cached data of the user end, and a delay time is adjusted, so that in a large-scale live broadcast scenario, a player can dynamically control, according to the network status of each user, a delay time of each user end in real time, and improve the viewing experience of user.

A method may comprise collecting data from a core network, an operator network and a customer premise network. KPI values corresponding to one or more KPIs may be determined, based on the collected data. KQI values corresponding to one or more KQIs may be determined, based on the one or more of the determined KPI values. The determined KQI values may be output to an operator. In an embodiment, data collected from the core network may include data collected from one or more analyzer devices and head end probes. Data collected from a customer premise network may include data collected from last mile equipment or customer premise probes.

Systems and methods are described herein for generating a playlist for a simultaneous presentation of a plurality of media assets. The system retrieves a user preference associated with a user profile and receives a selection of a first media asset and a second media asset from the plurality of media assets for presentation on a user device. The system parses the respective audio streams of the first media asset and the second media asset to identify one or more preferred audio segments based on the user preference and generates the playlist of the identified one or more preferred audio segments. Based on a generated audio playlist, the system generates, for presentation on the user device, the video stream for each of the first media asset and the second media asset and the playlist of the identified one or more preferred audio segments.
