A method includes: sending, upon receipt of an audio-only playing instruction in a process of synchronously playing audio and video of streaming media content using DASH, a request of obtaining audio data files of the streaming media content to a server, wherein video data files formed according to video content of the streaming media content and the audio data files formed according to audio content of the streaming media content are stored in the server; receiving the audio data files of the streaming media content from the server, and parsing out the audio content according to the audio data files; performing audio-only playing for the streaming media content according to the audio content.

Switch of audio and video

A method includes: obtaining a video data file and an audio data file of streaming media content to be played from a server, when the streaming media content is played using DASH; obtaining a video bitrate from the video data file, and obtaining an audio bitrate from the audio data file; and determining a capacity of a video buffer area and a capacity of an audio buffer area according to the video bitrate and the audio bitrate.

Balance of initial frame and limitation of traffic

A method of measuring a network speed, a computing device, and a computer-program product are provided. The method includes: obtaining a downloading duration and a downloading byte count of each of N consecutive video segments upon receiving a network speed measurement command during downloading video content, wherein the video content comprises multiple video segments; calculating out a total downloading duration and a total downloading byte count of the N video segments according to the downloading duration and the downloading byte count of each of the N video segments; and calculating out a current network speed according to the total downloading duration and the total downloading byte count.

Method for measuring network speed, computing device, and computer-program product

A method of playing audio and video is provided. The method includes: obtaining a streaming media content to be encapsulated, and parsing the streaming media content to obtain audio parameter information and/or video parameter information; forming a Media Presentation Description (MPD) file in JavaScript Object Notation (JSON) format according to the audio parameter information and/or the video parameter information, wherein the MPD file in JSON format includes multiple streaming media content segments, each streaming media content segment includes a video segment and/or an audio segment, each of the video segment and the audio segment includes multiple arrays, and each array includes the audio parameter information or the video parameter information; sending the MPD file in JSON format to a client.

Method of playing audio and video, computing device, and computer program product

A system includes reception of a first instruction at a first system to effect a first change to a hierarchy data model, storage of a first record including first values specifying the first change in a local memory of the first system, reception of a second instruction to effect a second change to the hierarchy data model, storage of a second record including second values specifying the second change in the local memory of the first computer system, reception of an instruction to save the changed hierarchy data model, and, in response to the instruction, transmit the first record and the second record to a second system. The first record and the second record are received and merged to generate a third record including third values specifying a third change to the hierarchy data model, and a query language statement is generated to effect the third change to the hierarchy data model based on the third record.

Action queue for hierarchy maintenance

A method of switching resolution is provided. The method includes: in playing audio and/or video using DASH, acquiring a media presentation description (MPD) file and obtaining resolution information through parsing the MPD file; during the playing of the audio and/or video, periodically determining a currently secure downloading speed according to a preset time interval and determining whether a resolution switching for the audio and/or video currently being played is required according to the secure downloading speed and the resolution information; and in accordance with a determination that the resolution switching is required, determining a switching time point according to an elapsed duration of a currently playing segment and a preset secure buffering duration and performing resolution switching at the switching time point.

Described herein is a framework for providing data model views with complex calculation capability. In accordance with one aspect, the framework receives a request to calculate target results. An object in an application layer may be invoked to perform complex calculation to generate intermediate results. The intermediate results are stored in a global temporary table. A data model view in a database layer may then be invoked to calculate the target results based on the intermediate results retrieved from the global temporary table. The calculated target results are then returned.

Data model view with complex calculation capability

The disclosure generally describes computer-implemented methods, software, and systems for allowing provisioning of open data protocol (OData) services on top of a generic interaction layer (GenIL). One computer-implemented method includes receiving an OData-compliant request for data, determining a GenIL data provider to receive the OData-compliant request for data, determining the memory location of the data, requesting the data from the determined memory location, receiving the requested data from the determined memory location, converting, using at least one computer, the received data into an OData-compliant format, rendering an OData-compliant response, and transmitting the OData-compliant response.

OData service provisioning on top of GenIL layer

Database data is unmasked in order to facilitate its efficient handling by a database engine. In response to a request for data of a masked table including a masked element, an engine identifies a mask interval, and then performs a first join with unmasked elements sharing a common key. The table resulting from this first join is then grouped according to a highest level location of the mask. A second join is then performed between the results of this grouping and the mask interval, to produce a corresponding unmasked table including a plurality of unmasked elements corresponding to the masked element. Unmasking according to embodiments may be particularly useful in leveraging processing power of an in-memory database engine, allowing it to efficiently perform batch processing of requests for masked data received from software of an overlying application layer.
