METHODS AND DEVICES FOR IMAGE LOADING AND METHODS AND DEVICES FOR VIDEO PLAYBACK
The present disclosure provides methods and devices for image loading. The method includes generating a request message requesting downloading compressed texture data corresponding to a basic image; sending the request message to a server; receiving compression format data sent by the server according to the request message; and sending to a GPU the texture data contained in the compression format data. The present disclosure provides methods and devices for video playback. The method includes extracting webpage source code corresponding to a webpage address entered by a user; determining in the source code a video link address containing a preset protocol header; obtaining an address editing rule and a video player corresponding to the preset protocol header; according to the address editing rule, editing the information and the video link address in the source code into a video playback address containing a preset protocol header; and playing a video resource corresponding to the video playback address.
SELECTION OF VIDEO SEGMENTS FOR ADAPTIVE STREAMING
Disclosed herein are system, apparatus, article of manufacture, method, and/or computer program product embodiments for selection of video segments for adaptive streaming. An embodiment operates by receiving one or more variant segments, the one or more variant segments including an old bitrate variant segment having an old bitrate and a new bitrate variant segment having a new bitrate for decoding, and playback. The embodiment farther operates by generating an old bitrate packetized elementary stream (PES) collection based on the old bitrate variant segment and a new bitrate PES collection based on the new bitrate variant segment and determining a first in-tolerance splicing location between the old bitrate PES collection and the new bitrate PES collection based on a maximum tolerance offset. The embodiment still further operates by splicing the old bitrate PES collection and the new bitrate PES collection based on the first in-tolerance splicing location.
EXTENDED SELECTION AND ALIGNMENT OF VIDEO SEGMENTS FOR ADAPTIVE STREAMING
Disclosed herein are system, apparatus, article of manufacture, method, and/or computer program product embodiments for extended selection and alignment of video segments for adaptive streaming. An embodiment operates by receiving variant segments, the variant segments including a first and a second variant segment having a first bitrate, and third and fourth variant segments having a second bitrate, for decoding and playback, generating a first, second, and third packetized elementary stream (PES) collections based on the first, second, and third variant segments. The embodiment further operate by storing the generated first, second, and third PES collections in a processing buffer, and determining, based on a maximum tolerance offset, a first and a second out-of-tolerance splicing locations and associated first and second out-of-tolerance offsets between the first PES collection and the second PES collection and between the first PES collection and the third PES collection.

The embodiment further operates by storing the generated first PES collection and second PES collection in a processing buffer; and determining a first out-of-tolerance splicing location and associated first out-of-tolerance offset between the first PES collection and the second PES collection based on a maximum tolerance offset.
Method for transmitting/receiving internet-based content and transmitter/receiver using same
The present invention relates to a method for transmitting/receiving contents through a network such as the Internet, and to a transmitter/receiver using same, the transmission method comprising: converting content stored in a file format into a delivery format; and transmitting the content converted into the delivery format using an IP packet, wherein the delivery format includes indicator information for expressing whether a program clock reference (PCR) has been transmitted to the IP packet.
TRANSMISSION DEVICE, TRANSMISSION METHOD, RECEPTION DEVICE, AND RECEPTION METHOD
A technique capable of allowing a reception side to easily select components is provided. A transport stream in which a first transport packet including predetermined components and a second transport packet including signaling information related to the predetermined components are time-division multiplexed is transmitted via a predetermined transport path. Component selection information is inserted in the second transport packet. The component selection information includes information on a selective layer in which static selection is performed, information on a composite layer in which composition is performed, and information on an adaptive layer in which dynamic switching is performed, and these layers being arranged in that order from top to bottom. The acquisition destination information of a component which is a target of adaptive switching among the components selectable in the adaptive layer is information that designates specific information location of a metafile having data stream acquisition information for adaptive streaming.
Method, device and system for evaluating user experience value of video quality
Embodiments of the present disclosure provide a method, a device and a system for evaluating a user experience value of video quality. The method is: acquiring an uplink packet of a user equipment for requesting to watch an OTT video, where the uplink packet is transmitted by the user equipment to a video server storing the OTT video and carries request information of the user equipment on the OTT video; acquiring a downlink packet corresponding to the uplink packet, where the downlink packet is transmitted by the video server to the user equipment and carries the OTT video, and the OTT video is transmitted by the video server according to the request information in the uplink packet; buffering the downlink packet; and in response to determining that the buffered downlink packet satisfies a resolving condition, resolving the OTT video in the buffered downlink packet to generate a user experience value.
Method for transmitting a broadcast service, method for receiving a broadcast service, and apparatus for receiving a broadcast service
A method to receive a broadcast includes parsing a first trigger for obtaining a first identifier for identifying a targeted Triggered Declarative Object (TDO), and a preparation trigger time for the targeted TDO; parsing a second trigger for obtaining an activation time and a termination time for the targeted TDO; activating the targeted TDO corresponding to the first identifier on a background, when a receiving time of the preparation trigger is before the preparation trigger time, immediately activating the targeted TDO corresponding to the first identifier on the background, when the receiving time of the preparation trigger is after the preparation trigger time; changing a state of the targeted TDO to a foreground, when a current system time is after the activation time; and terminating the targeted TDO, when the current system time is after the termination time.
