  • TECHNIQUE FOR SYNCHRONIZING RENDERING OF VIDEO FRAMES WITH RENDERING OF AUXILIARY MEDIA
    Publication number: 20200029116
    Abstract: The present disclosure relates to synchronizing the rendering of video frames included in media file segments with the rendering of auxiliary media. A method implementation of this technique comprises the step of determining, from a sequence of media file segments, a sub-sequence of media file segments, wherein rendering of the sub-sequence is to be overlaid by rendering of auxiliary media starting in a first media file segment of the sub-sequence. The method further comprises determining control information enabling a media client to determine how much rendering of the auxiliary media has progressed upon rendering of each media file segment of the sub-sequence, and initiating a tagging of the media file segments of the sub-sequence with the control information.

  • Technique for detecting an encoder functionality issue
    Patent number: 10440084
    Abstract: A technique for detecting an encoder functionality issue in a media distribution system is presented. In the media distribution system consecutive media segments generated by an encoder are transmitted to a media client, and media descriptions describe expected availability times of media segments for the media client. A method implementation of the technique comprises the step of monitoring an availability time of a media segment compared to an expected availability time of the media segment, wherein the expected availability time is described by, or derived from, a media description. The method further comprises determining whether a deviation of the monitored availability time of the media segment from the expected availability time of the media segment is present, and detecting the encoder functionality issue based on a result of the determination. The encoder functionality issue may comprise one or more of an encoder restart, an encoder malfunction and an encoder time drift.

  • Technique for Selecting a Content Distribution Network Entity
    Publication number: 20190215361
    Abstract: A selecting apparatus configured to select out of a set of content distribution network (CDN) entities a CDN entity for distributing content to a client device is described. Content distribution by a CDN entity is associated with a resource consumption, for example in regard of processing load. The selecting apparatus is configured to receive service performance reports for multiple CDN entities of the set of CDN entities and to select, upon determining from one or more of the service performance reports that a service performance of a first CDN entity is above a first result, a second CDN entity for content distribution to a client device. The selection is performed subject to the constraints that a service performance of the second CDN entity is below a second threshold and resource consumption in regard of the second CDN entity is lower than a resource consumption in regard of the first CDN entity.

  • Processing of data files
    Patent number: 10334018
    Abstract: In general, it is proposed to define a new expiry mechanism for a data file being received at the client. In the following it is proposed that the expiry time on the receiver side should be “shortly” after a possible reception of all packets. It is proposed that the receiver should know as precisely as possible that no additional packets for that data file are expected anymore. As soon as the receiver can safely regard the reception of the file, the receiver could either move on to the next segment (delay optimization) or try to make use of the received information.

  • System and Method for Interactive 360 Video Playback Based on User Location
    Publication number: 20190179145
    Abstract: A system, method, and Head-Mounted Display (HMD) apparatus for recording a video and playing back the video to a viewer in a Virtual Reality (VR) environment. A geographical area is recorded with an omnidirectional video recording camera by dividing the geographical area into a plurality of area portions and recording in separate video sections, each of the area portions while moving the camera in different directions. Time points in each video section are associated with virtual locations of the viewer. At a time point providing the viewer with a choice of directions to proceed, the system receives the viewer's choice and presents to the viewer, a video section corresponding to the virtual location of the viewer and the desired direction of movement. The viewer's choice may be indicated by detecting a direction of the viewer's field of view or by receiving from the viewer, a response to a banner notification.
