Business Challenges
  • Heavy Computing Workload

    As video resolution improves from 360P to 4K, the computing workload of video encoding increases by more than 90 times. Existing servers in the data centers are becoming strained with the workloads.

  • Video Fluency

    Most viewers can only enjoy a 4 Mbit/s bandwidth when viewing videos. To provide smoother watching experience for customers with this bandwidth limitation, complex video encoding algorithms are required to lower the transmission bandwidth and improve image quality.

  • High CDN Expenditure

    CDN is a major cost center in the operation of live video platforms. The expenditure on encoding computing can lower the transmission bandwidth without affecting the image quality. This can help reduce the CDN expenditure.

  • Demand Spikes

    Viewing of live video platforms has a demand spike in the evening. Self-built data centers are not the most economical solution to respond to the demand spike.

Product Advantages
  • Various Standards

    Supports H.265 and H.264 encoding standards, provides high-quality, high-density, and low-latency hardware encoders, and meets a variety of encoding requirements.

  • Ultra HD

    In the 4K ultra HD field, hardware encoders can greatly improve the video encoding efficiency. HUAWEI CLOUD FPGA Video Transcoding Acceleration supports AV1 and H.265 standards, helping the video industry quickly achieve HD. Open Beta Test versions of two types of hardware encoders will be provided in early 2019.

  • High Efficiency

    In the live broadcast scenario, encoding tasks must be processed in real time. FPGA hardware encoders provide an industry-leading compression ratio to improve user experience as well as process tasks in real time.

  • High Performance

    Video defragmentation imposes great pressure on short video encoding. High-performance hardware video encoders can help short video platforms meet encoding requirements, improve video definition and user experience, and reduce the space for storing videos.

Application Scenarios
  • Internet Live Broadcast

  • Short Video Transcoding

  • Radio and TV Broadcast

Internet Live Broadcast

Internet Live Broadcast

Live broadcast services on the Internet require real-time transcoding and acceleration, and a balance must be stricken between the compression rate and real-time performance. Traditional CPU encoders cannot efficiently process HEVC and AV1 algorithms with high encoding complexity. The FPGA Video Transcoding Acceleration service doubles transcoding performance and lowers the power consumption ratio by three times, helping live broadcast platforms provide HD videos.

Advantages

Higher Performance and Lower Power Consumption Ratio

Test results show that FP1 single-card instances support 4-channel 720P30 (H.265) and 12-channel 720P30 (H.264), outperforming CPU ECSs of the same specifications and cutting power consumption in half.

Flexible and Programmable

In contrast to ASIC hardware, FPGA is flexible and programmable. It is suitable for applying encoding algorithms to hardware when the encoding standards change frequently. You can deploy H.264, H.265, and next-generation AV1 algorithms as needed.

Scalable

Compared with encoding servers of self-built data centers, the FPGA Video Encoding Acceleration service enables you to expand capacity during peak hours and process burst traffic on the cloud.
