A method of and system for handling latency issues encountered in producing real-time entertainment such as games of skill synchronized with live or taped televised events is described herein. There are multiple situations that are dealt with regarding latencies in receiving a television signal with respect to real-time entertainment based on the unfolding games played along with the telecasts. Systemic delays, arbitrarily imposed delays of a broadcast signal and variances in the precise broadcast times of taped television programs have to be equalized so as to provide fair entertainment.

Aspects of the disclosure provide methods, apparatuses, and non-transitory computer-readable mediums for receiving media data of media content. One apparatus includes processing circuitry that receives a media presentation description (MPD) file and a session-based description (SBD) file. The processing circuitry determines whether the SBD file includes a starting time attribute indicating a starting time of an SBD timeline of a session. The processing circuitry determines the starting time of the SBD timeline based on the SBD file in response to the SBD file including the starting time attribute. The processing circuitry determines the starting time of the SBD timeline based on the MPD file in response to the SBD file not including the starting time attribute.

According to embodiments, the invention provides a method for encapsulating partitioned timed media data comprising timed samples, comprising in turn subsamples, the timed samples being grouped into groups, the method comprising: obtaining spatial tracks, each spatial track comprising at least one subsample of a first timed sample and one corresponding subsample of the other timed samples, the corresponding subsamples being located at the same spatial position in its own timed sample as the at least one subsample; creating a base track referencing at least some of the spatial tracks, the base track comprising reconstruction instructions, each of the reconstruction instructions being associated with a group of timed samples, enabling generating a portion of a bit-stream from sub-samples of spatial tracks, that belong to a same group of timed samples; and independently encapsulating each of the tracks in a least one media file.

Both a conventional receiver and an HDR-compatible receiver well perform electro-optical conversion processing on transmission video data obtained by using an HDR opto-electronic transfer characteristic. High dynamic range opto-electronic conversion is performed on high dynamic range video data to obtain the transmission video data. Encoding processing is performed on this transmission video data to obtain a video stream. A container of a predetermined format including this video stream is transmitted. Metadata information indicating a standard dynamic range opto-electronic transfer characteristic is inserted into a layer of the video stream, and metadata information indicating a high dynamic range opto-electronic transfer characteristic is inserted into at least one of the layer of the video stream and a layer of the container.

An interactive user interface, such as a remote terminal user interface, is compressed prior to transmission to a video client. The compression may be performed independently of any other video that may be simultaneously transmitted to the video client. At the client side, two compressed video streams (remote user interface and video content) may be decompressed independently of each other. In some cases, technology already existing in some client devices, such as picture-in-picture (PiP) capability, may be leveraged to decompress the received compressed remote user interface without needing to modify the hardware of those client devices.

The techniques described herein relate to methods, apparatus, and computer readable media configured to access multimedia data comprising a hierarchical track structure comprising at least a first track at a first level of the hierarchical track structure comprising first media data, wherein the first media data comprises a first sequence of video media units, and a second track at a second level in the hierarchical track structure different than the first level of the first track, the second track comprising metadata specifying a re-timing derivation operation. Output video media units are generated according to the second track, comprising performing the re-timing derivation operation on the first sequence of video media units to modify a timing of the first sequence of video media units by removing one or more video media units associated with the re-timing derivation operation and/or shifting timing information of the first sequence of video media units.

Systems and methods are described herein for a media guidance application to determine that a user has switched away from a source transmitting a media asset with which the user was engaged and detect, while the user is switched away from the source, that secondary content transmitted by the source during a break of playback of the media asset relates to the media asset. In response to detecting that the secondary content relates to the media asset, the media guidance application may access a database to determine whether the secondary content specifically corresponds to the media asset, and, in response to determining that the secondary content specifically corresponds to the media asset, the media guidance application may generate for display the secondary content to the user.
