摘要: Systems and methods for providing variable trick-play mode playback of media content in accordance with embodiments of the invention are disclosed. A playback device stores images of the media content associated with presentation times and marker information for the media content that indicates the presentation time of moments of interest. When a trick-play mode is invoked, the playback device determines a presentation time of a next marker in the playback. The playback device determines whether the current presentation time of the playback is within a specified range of the presentation time of the next marker and adjusts the speed of the trick-play playback based on the determination. The next frame to present is determined based on the adjusted speed of the trick-play playback and displayed.

摘要: The present invention relates to a method for playing on a player of a client device (11) a content streamed in a network (1), said content consisting of a sequence of segments available in a plurality of quality levels, the player being configured so as to choose the quality level of the segments as a function of at least one parameter representative of a segment reception rate, according to an Adaptive BitRate, ABR, logic of the player; the client device (11) comprising a first buffer (M1) for storing segments in a format adapted for transferring within the network (1), the method being characterized in that it comprises performing by a processing unit (110) of the client device (11):
(a) receiving from the player a request for a current segment at a first quality level;
(b) determining that the player will request according to its ABR logic a next segment at a second quality level after said requested current segment is provided from the first buffer memory (M1), using a model predicting the ABR logic of the player;
(c) if said next segment is not present at said second quality level in the first buffer memory (M1), fetching said next segment at said second quality level from the network (1).-

摘要: A set-top box for changing channels and method for use of the same are disclosed. In one embodiment, the set-top box includes a network interface controller that is configured to receive a source internet protocol television signal, which includes two channels, from an external source and at least partially prepare the source internet protocol signal in order to forward the tuned signal to a television. The set-top box saves in a buffer the at least partially prepared second channel beginning at a recent periodic, sequential signal access point. In response to receiving a channel change instruction when the set-top box is forwarding the at least partially prepared first channel signal, the set-top box causes the television tuner to forward the at least partially prepared signal based on the second channel stored in the buffer beginning at the recent periodic, sequential signal access point.

摘要: Apparatus and methods for content fragmentation, distribution, protection, and re-constitution within a content distribution network. In one embodiment, the apparatus and methods enable distribution of content fragments to edge nodes (which may include user or subscriber CPE), thereby enabling edge networks or membership groups to be established wherein content can be shared solely at the edge. In one variant, high data bandwidth, symmetric uplink/downlink, low latency PHY links (e.g., 5G NR-compliant wireless interfaces) between the edge nodes participating in the edge networks or membership groups are used such that particular quality of service/experience performance requirements can be met. Distribution of the fragments also advantageously enhances redundancy and security.

摘要: Systems and methods are disclosed herein for providing in-vehicle content. Audio of media content is provided to a vehicle. The vehicle is determined to be approaching a location for stopping. A predicted stop duration is calculated during which the vehicle will be stopped at the location. A playlist of video portions of the media content is generated based on the predicted stop duration. The vehicle is detected to have stopped at the location. The video portions are generated for displaying while the vehicle is stopped at the location.

摘要: A method for storing a coded video bitstream. The method includes obtaining the coded video bitstream and storing the coded video bitstream in at least one storage medium. The coded video bitstream includes a first reference picture list syntax structure and a second reference picture list syntax structure. Each reference picture list syntax structure contains a number of entries. A first reference picture list of a current slice and a second reference picture list of the current slice are derived based on the first reference picture list syntax structure and the second reference picture list syntax structure. The first reference picture list and the second reference picture list are derived for bitstream conformance checking instead of for decoding a current picture or pictures following the current picture in decoding order when the current slice comprises an intra (I) slice of a non-intra random access point (IRAP) picture.

摘要: The invention provides a method of media content delivery, where the time taken to deliver each chunk of content is measured, from which the stability or consistency of delivery times are calculated. The amount of data buffered at the user's device awaiting decoding and play-back can then be adjusted (such as by playing out the content slower or quicker), in order to achieve a good compromise between continuous play-out and low end-to-end delay, taking into consideration the current network characteristics.

摘要: Systems, apparatuses, and methods are described for encoding media content based on an ending delay of first media content and a startup delay of second media content. Second media content may be configured for transmission after first media content in a media content stream. The first media content may be associated with an ending delay corresponding to transmission and/or decoding of frames of the first media content. The second media content may be associated with a starting delay corresponding to transmission and/or decoding of frames of the second media content. The first media content and the second media content may be encoded using different encoding formats. Based on comparing the ending delay and starting delay to a threshold, encoding parameters may be selected, one or more frames may be removed from the first media content and/or the second media content, and/or buffers of one or more devices may be adjusted.

摘要: Systems and methods are disclosed for generating a content structure that can then be used as a content design building block. Specifically, new content can be automatically generated by combining, replacing or mixing and matching objects, actions, settings, effects, audio, etc., from any number of previously stored content structures to create a new content structure, which is then rendered as a new content segment. Content segments are then stitched together to generate a finished content stream. In this way, new and original content can be created without the traditionally expensive and labor-intensive filming or computer animation processes.
