Introduction:
As a international leading brand of encoders, PowerSmart has recently released the HEVC Encoder for Live Broadcast, which is the first broadcast quality in domestic market. The encoder has achieved a series of breakthroughs over various technical difficulties. It adopts parallel computing technologies and performance optimization technologies to conduct real-time processing for highly complex tasks requiring intensive computing. Different from some of the domestic and international encoders that sacrifice video qualities for real-time processing, the PowerSmart Encoder is able to adopt the most quality optimization algorithms of the HEVC specifications, so that it is obviously of excellent competitiveness.

The PowerSmart Encoder enjoys an excellent reputation and a high market share in the industry. The product is the first one that has achieved various original technologies under the H.264 standards, such as the low bandwidth optimization for iPhone, parallel encoding with multi-bitrate , internet rate control, automatic loudness balance, dynamic definition optimization, etc. These original technologies have always retained their advantages over their international counterparts in terms of sports programs, roll titles, loudness control, and adaptive multi-bitrate , etc. Recently, PowerSmart has released the latest HEVC Encoder for Live Broadcast. Doubtlessly, the new Encoder under the HEVC standards has ushered in a new era for the PowerSmart products. Meanwhile, the company’s tradition of catering to customer demands is demonstrated again.
Advantages of HEVC over H.264：
The HEVC (High Efficiency Video Coding or H.265) is a new set of video encoding standards, the successor to H.264. Compared to H.264, HEVC has experienced many revolutionary changes in different aspects.：
1. The adaptive motion vectors allow this encoding system to spot more inter-frame redundancy.
2. Excellent parallelization tools, including the tool that allows Wavefront Parallel Processing(WPP) in multi-core conditions for more efficient encoding.
3. Improvements on de-blocking filter and the establishment of the secondary filter, which is also known as sampling adaptive compensation that can further restrict edge distortion.
Seeing from the final outcome, the HEVC real-time encoder provides better terminal experience：
1. HEVC brings huge bandwidth savings more than 40% over H.264/AVC encoded content with same quality.
2. Higher PSNR: Subjective viewing test shows that HEVC’s quality is equal to, even better than H.264 with a bitrate reduction of 51-74%.
Based on the HEVC encoding and decoding standards, the PowerSmart Real-time Encoder has achived the following features:
1. Stable and smooth playback for multi-screen have reached the most advanced level in domestic market;
2. Adaptive multi-bitrate has attained the fastest and most stable speed for transmission;
3. Overcoming the defect of real-time encoding gained through sacrificing video quality.
PowerSmart HEVC Encoders for Live Broadcast are now in service for our clients. PowerSmarts will continue to optimize the performance of HEVC Encoders, lower the costs of devices, and contribute to the promotion of this technology, so as to help our partners retain their advantageous position in the fields of video application and promotion.
