Network Video Streaming with Trick Play Based on Separate Trick Play Files
20180007451 · 2018-01-04 · ·

Network services encode multimedia content, such as video, into multiple adaptive bitrate streams of encoded video and a separate trick play stream of encoded video to support trick play features. The trick play stream is encoded at a lower encoding bitrate and frame rate than each of the adaptive bitrate streams. The adaptive bitrate streams and the trick play stream are stored in the network services. During normal content streaming and playback, a client device downloads a selected one of the adaptive bitrate streams from network serviced for playback at the client device. To implement a trick play feature, the client device downloads the trick play stream from the network services for trick play playback.

A Method, An Apparatus and a Computer Readable Storage Medium for Video Streaming

A method comprising: requesting, by a client, an independently coded first representation of a video content component from a server; receiving and playing a first set of data units of the independently coded first representation; requesting a second set of data units of a second representation, said second set of data units being dependently coded on one Receive and play a first set of data units of or more requested or buffered data units of the first set; and requesting a third set of independently coded data units of a third representation.

METHODS AND ELECTRONIC DEVICES FOR DYNAMIC CONTROL OF PLAYLISTS
20180004480 · 2018-01-04 ·

This disclosure concerns the playback of audio content, e.g. in the form of music. More particularly, the disclosure concerns the playback of streamed audio. In one example embodiment, there is a method of operating an electronic device for dynamically controlling a playlist including one or several audio items. A request to adjust an energy level (e.g. a tempo) associated with the playlist is received. In response to receiving this request, the playlist is adjusted in accordance with the requested energy level (e.g., the tempo).

METHODS AND SYSTEMS FOR ALERTING USERS REGARDING AVAILABILITY OF UNCONSUMED CONTENT
20180007155 · 2018-01-04 ·

Methods and systems are described for a media guidance application that limits the incentive for authorized users to share content with unauthorized users, while still allowing users to access content virtually anywhere. Specifically, the media guidance application allows an authorized user to receive only a portion of a media asset that he or she is authorized to access on a different device, after a designated time period, and/or when the remaining portion of the media asset is inaccessible.

Tile shuffling for 360 degree video decoding

A decoder (100) receives (30) a set of N compressed segments of a first picture, and a set of M compressed segments for a second picture that follows the first picture in a decoding order. Based on the set of N compressed segments, the decoder constructs a decodable picture for the first picture and decodes (32) the decodable picture. Based on the set of M compressed segments, the decoder constructs a decodable second picture in the compressed domain, in which each of the segments of the first picture are placed at the same spatial position as that of a corresponding segment in the second picture, and decodes (52) the decodable second picture. Additionally, at least one Intra coded segment is placed at one of the M spatial positions in the compressed domain in which there is no segment of the N segments.

Viewport dependent delivery methods for omnidirectional conversational video

A user equipment, media control unit, media resource function, or another device or function capable of receiving, manipulating, and transmitting data may be configured to: receive an omnidirectional video; determine a viewport of a user equipment; determining a delivery mode; determine a region of the omnidirectional video based, at least partially, on the determined viewport and the determined delivery mode; encode the determined region; packetizing the encoded region; and transmit the packetized region to the user equipment based, at least partially, on the determined delivery mode.

Methods and systems for graphics rendering assistance by a multi-access server

An illustrative multi-access server receives a request from a client system, the request indicating a requested rendering operation. The multi-access server also accesses input data from an asset data source. The multi-access server performs a rendering pass on the input data, the rendering pass performed in accordance with the requested rendering operation to generate a render pass output dataset. The render pass output dataset is representative of a renderable image depicting image content in a first form having limited quality or detail. The render pass output dataset is also configured for use in generating fully-rendered image data that depicts the image content in a second form having additional quality or detail beyond the limited quality or detail of the first form. Corresponding methods and systems are also disclosed.

Systems and methods for encoding and playing back video at different frame rates using enhancement layers
11711552 · 2023-07-25 · ·

Systems and methods in accordance with embodiments of this invention provide for encoding and playing back video at different frame rates using enhancement layers. In a number of embodiments, video is encoded using temporal scalability involving the creation of a base layer at a first frame rate and an enhancement layer including additional frames enabling playback at a second higher frame rate. The second higher frame rate can also be referred to as an enhanced frame rate. In a number of embodiments, the base and enhancement layers are stored in one or more container files that contain metadata describing the enhancement layer. Based on the capabilities of a playback device, it can select the particular frame rate at which to playback encoded video.
