A method for reducing artifacts in streaming video implemented by a computing device involves determining whether a video quality assessment score for a current segment of a channel of a video stream with a first resolution and a first bit rate meets a quality threshold, replacing the current segment with a replacement segment with a lower resolution than the first resolution, in response to the current segment failing to meet the quality threshold, and publishing the replacement segment at the first bit rate as part of the video stream.

Systems and methods are described for delivering regional content for a lineup over a national network. A content provider may select a particular regional broadcast for inclusion in a regional service lineup. The content provider may be able to broadcast multiple, or even all, services nationally. At regional distribution centers, a multiplexer may select only those services that are desired for the region in response to in-stream signals. In some instances, a single region-specific version of a given service may be selected from multiple versions broadcasted nationally. The regional lineup, including the selected services, can then be multiplexed and transmitted to customers throughout the region.

A transmission device according to the present disclosure includes: a transmission unit configured to output, to a transmission channel, a plurality of packets each including a payload and a header added to the payload, the payload including pixel data corresponding to one line included in an image of one frame; and an identification information adder that adds identification information of the pixel data to at least a partial region of the payload.

An ultrasound system with a multimedia information distribution system comprising: a video processor generating a sequence of video frames of at least the ultrasound diagnostic images of a sequence of ultrasound diagnostic images; a media editor for combining the ultrasound video frames with further audio/video data to generate multimedia data; a multimedia encoder encoding the multimedia data in the form of a multimedia file; a media streaming module receiving the said multimedia file and generating a real-time stream of the sequence of multimedia data encoded in the said multimedia file; a web server allowing access to the real-time stream of the multimedia data upon request by a remote client to access the said multimedia file. A corresponding computer implemented method is also disclosed.

This patent disclosure provides various embodiments of a client-server based digital video playback system and technique. In one aspect, a process for playing internet/online videos on a user device is disclosed. This process can begin by sending a video playback request for playing an online video to the server, wherein the video playback request includes a device type and a browser type of the user device. Next, the process receives a set of video playback addresses and a set of video playback configuration files from the server, wherein the set of video playback addresses and the set of video playback configuration files are generated based on the device type and the browser type. The process subsequently selects a video playback address from the set of video playback addresses corresponding to a transcoded version of the online video that matches a device version and a browser version of the user device. The process next obtains the transcoded version of the online video from the selected video playback address, and plays the obtained video on the user device.

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.

Aspects of the subject disclosure may include, for example, setting a streaming rate cap for a client device; obtaining a bitrate ladder associated with the client device, wherein the bitrate ladder comprises a listing of a plurality of bitrates that the client device can request in connection with receiving streaming data; determining a boost rate for the client device, wherein the boost rate is greater than the streaming rate cap such that the boost rate enables the client device to receive the streaming data faster than the client device would otherwise receive the streaming data under the streaming rate cap, and wherein the boost rate is based upon the bitrate ladder; and enabling delivery to the client device of the streaming data up to the boost rate; wherein a network device is part of a network through which the streaming data is delivered to the client device. Other embodiments are disclosed.

Embodiments of this application provide a video transmission method, apparatus, and system, to reduce an end-to-end transmission delay of video data. The method includes: A transmit end obtains a first frame of image of the video data, where the first frame of image includes a plurality of sub-images, and the plurality sub-images include a first sub-image and a second sub-image; the transmit end performs layered encoding on the first sub-image to obtain a plurality of layers of bitstreams of the first sub-image; the transmit end sends the plurality of layers of bitstreams of the first sub-image to a receive end; the receive end decodes the plurality of layers of bitstreams of the first sub-image to obtain the first sub-image.

Provided herein are various embodiments for synchronizing playback of audio and video. An embodiment operates by determining that a first quality video is being received at a media device. It is determined that a buffer of the media device is not large enough to buffer the first quality video long enough to synchronize an output of the high quality video with the output of the audio by one or more wireless speakers. A second quality of the video that the buffer can hold long enough to synchronize is identified, wherein the second quality of the video is lower than the first quality of the video. The media device outputs the video at the second quality and the corresponding audio to the one or more wireless speakers.
