Concepts

Stream Push

A process of transmitting collected, encoded, and packaged live content to the origin server

Stream Pull

A process of pulling live content from the origin server to a specific address for playback

Edge Streaming

A livestream is pushed to a nearby edge node. Then, the scheduling system of Huawei Cloud transmits the livestream to the origin server for processing and distribution. This ensures that the livestream is transmitted over the optimal uplink network, with minimized lags.

Streaming Domain Name

Domain name for playing livestreams. You must add a streaming domain name to Live before using Live. After a streaming domain name is added, a streaming URL will be generated. Then you need to assemble the streaming URL.

Ingest Domain Name

Domain name for pushing livestreams. You must add an ingest domain name to Live before using Live. After an ingest domain name is added, an ingest URL will be generated. Then you need to assemble the ingest URL.

CNAME Record

After ingest and streaming domain names are configured, the system assigns a respective CNAME record to the ingest and streaming domain names. You must add the records to your domains' DNS records for livestreaming acceleration to take effect.

H.264

H.264 or MPEG-4 Part 10, a video compression standard developed by the ITU-T Video Coding Experts Group (VCEG) and ISO/IEC JTC1 Moving Picture Experts Group (MPEG).

H.265

H.265 is a video compression standard, designed as a successor to H.264. Based on the video coding standard H.264, H.265 keeps some of the original technologies, while improves some relevant techniques. H.265 adopts the advanced techniques to improve the bit-stream, promote the coding quality, and better the relationship between time delay and algorithm complexity, to achieve best possible optimization. H.264 can transmit SD (resolution lower than 1280 x 720) digital images at a rate lower than 1 Mbit/s, whereas H.265 can transmit standard HD (resolution of 1280 x 720) audio and video at a rate of 1 Mbit/s to 2 Mbit/s.

Low-Bitrate HD

Based on the human visual system model and Huawei's transcoding technology, Live analyzes each scenario, action, content, and texture in a video to deliver lower bitrate while keeping the bandwidth costs down but without compromising the video quality.

Real-time Transcoding

A process of transcoding one livestream into another or more in real time to meet different bandwidth, device, and user requirements

Weak Network

The QoS of a weak network is not stable.

95th Percentile Bandwidth

A billing option. Within a calendar month, the bandwidth is measured and recorded every 5 minutes on each valid day. At the end of the month, the records are sorted from the highest to the lowest, and the top 5% of the recorded bandwidth values are thrown away. Then the highest bandwidth value in the remaining records is the billable bandwidth of the month.

Stream Name

This is used to identify a livestream with the domain name and App Name. Stream Name can be customized.

App Name

Path for storing streaming media files. The default value is live.

Livestreaming URL

This includes an ingest URL and streaming URL. A livestreaming URL consists of the domain name, App Name, and Stream Name. You can create multiple applications for each domain name, and create multiple livestreams for each application.
