摘要： The present disclosure provides a method for playing an MP4 online, an electronic device, and a computer readable storage medium. The present disclosure relates to the technical fields of artificial intelligence, and further relates to the technical fields of media cloud. A specific embodiment of the method includes: acquiring a total size of a target MP4 file, and determining a target data length based on the total size and a preset proportion, where the preset proportion is determined based on a proportion of MOOV data to a complete MP4 file; acquiring header data having the target data length from a header of the MP4 file, and acquiring trailer data having the target data length from a trailer of the MP4 file; and playing the target MP4 file online based on actual MOOV data extracted from the header data or the trailer data.

摘要： Methods and systems for delivering content are described. A content distribution network may utilize multiple content sources and datacenters when delivering content to a requesting device. One or more service metrics associated with the content as it is being prepared for delivery at each of the datacenters may be monitored by a quality agent. The quality agent may use the one or more service metrics to select a distribution datacenter to deliver the content to the requesting device. The quality agent may instruct the remaining datacenters to disable delivery of the content to the requesting device.

摘要： Example embodiments provide systems and methods for crowdsourced skipping of media content portions. In an example method, a plurality of content tags are received from a plurality of media content devices over a communication network. Each of the plurality of content tags may designate a location within a media content item. The content tags are processed to generate aggregated content tags for the media content item. The aggregated content tags may designate one or more portions of the media content item for modified playback. The aggregated content tags for the media content item are transmitted over the communication network to a first media content device separate from the plurality of media content devices.

摘要： The disclosure generally relates to a method for accessing media content, said method being used in a receiver. The method comprises a preparation phase and a use phase. The preparation phase comprises the steps of obtaining, by said receiver, a catalog of media content items, each media content item corresponding to a media content and comprising at least an item description and an item identification data and storing said catalog of media content items in a local database in a memory of the receiver. The use phase comprises the steps of accessing, by a mobile display device, said catalog of media content items through a local communication channel; displaying at least a part of the catalog of media content items on the mobile display device; selecting, by said mobile display device, at least one media content item displayed on the mobile display device; transmitting, by said mobile display device, a request to a content provider, the request comprising the item identification data corresponding to said selected media content item and additional data allowing for the receiver to be identified, said transmission using a first remote communication channel distinct from said local communication channel; and obtaining by the receiver, the media content corresponding to the media content item identified by the identification data contained in said request.
The disclosure further relates to a receiver and a mobile display device for implementing the above described method and a system comprising at least said receiver and said mobile display device.

摘要： A method and system for rendering a HTTP Live Streaming video stream on a display includes a player receiving a master manifest from a network device in response to selecting a video channel. The player also receives a plurality of variant manifests referenced by the master manifest from the network device, where each of the variant manifests references video files each of which having a different bit rate for the same video stream. The player simultaneously maintains the variant manifests in the player. The player determines an effective start time of the video stream based upon the selecting video channel where the effective start time is a time later than an earliest time referenced in the plurality of variant manifests. The player enables reverse of the video stream based upon one of the variant manifests to as early as the effective start time and not enabling reverse of the video stream based upon one of the variant manifests to a time earlier than the effective start time.

摘要： Systems and methods of combining digital video are described. A system can receive digital video comprising frames. The system can analyze the frames to identify a subset of consecutive frames that have a static portion defined by a spatial region with matching pixels across two or more frames. The system can tag the digital video with an indication of the subset and a trigger that causes transmission, at a temporal offset during playback prior to the subset, of a request for content used to overwrite the static portion. The system can receive the request from the client device, the request transmitted by the client device based on the temporal offset during playback prior to the subset. The system can select and transmit a content item responsive to the request to cause the client device to render the content item at the static portion of the subset.

摘要： A system for quantifying viewer engagement with a video playing on a display includes at least one camera to acquire image data of a viewing area in front of the display. A microphone acquires audio data emitted by a speaker coupled to the display. The system also includes a memory to store processor-executable instructions and a processor. Upon execution of the processor-executable instructions, the processor receives the image data and the audio data and determines an identity of the video displayed on the display based on the audio data. The processor also estimates a first number of people present in the viewing area and a second number of people engaged with the video. The processor further quantifies the viewer engagement of the video based on the first number of people and the second number of people.

摘要： A video stream processing method and apparatus are provided. The method includes obtaining an image set of a target person from a multi-channel video stream, the multi-channel video stream being obtained for a same scene by a plurality of cameras, and an image in the image set includes a front face image of the target person; determining a virtual viewpoint in a target-person view mode based on the image in the image set; and projecting, based on a depth map of a target image and a pose of a real viewpoint corresponding to the target image, the target image onto an imaging plane corresponding to the virtual viewpoint to obtain a video stream in the target-person view mode, the target image intersecting with a vision field of the target person in the multi-channel video stream.

摘要： Systems and methods for determining whether a first electronic device detects a media item that is to be output by a second electronic device is described herein. In some embodiments, an individual may request, using a first electronic device, that a media item be played on a second electronic device. The backend system may send first audio data representing a first response to the first electronic device, along with instructions to delay outputting the first response, as well as to continue sending audio data of additional audio captured thereby. The backend system may also send second audio data representing a second response to the second electronic device along with the media item. Text data may be generated representing the captured audio, which may then be compared with text data representing the second response to determine whether or not they match.
