Based on several years of video codec technology, excellent video capturing, processing, and streaming technology since 2007, Hisight provides encoder/decoder solution and service for broadcasters, with rapid, reliable contribution of superior-quality content. At present, Hisight contribution encoder had been applied for the relay of sport and large-scale event in China.
Hisight closely cooperates with Socionext who is the world leading video ASIC vendor, to provide the complete solutions and services for broadcasters and media workers, and accelerate and improve the quality and user experience of video transmission through 5G networks, while reducing the time to the markets of products.
With the coming of 5G Era, contribution solution tend to be IP-based. In order to meet the needs of efficient delivery of high-quality video through 5G, Hisight integrates the advantages of Socionext encoder SoC and Hisight's embedded video processing technology, and launches HEVC contribution encoder and decoder solution based Socionext SoC, to create a high-quality, low bandwidth and low power consumption experience for professional users.

Socionext Leading Video Processing Engine Socionext is a leading company who realized a real-time encoder with broadcasting quality compatible with the most advanced H.265 (HEVC) format on a single chip for the first time ever. The performance and image quality of their encoder SoC are highly admired by professionals in the field of imaging. Socionext had become the best choice for broadcaster to process video codec. |

Professional AV Acquisition Interface Based on leading image acquisition and processing technology, Hisight is good at applying FPGA to integrate AV acquisition interface into encoder, to realize all of video definition and frame rate capturing. GT4K-3001E can accept either 4K signals over 12G-SDI, or a quad 3G-SDI to deliver a full-4K stream. Multiple processes had been performed on each input by powerful scaling and de-interlacing engines to reduce the requirement for both camera and monitor. Different with video capture card, such embedded AV acquisition solution makes compatibility, stability, and low latency by data delivery to encoder directly through on-board video bus. |

Flexible Streaming Protocols Hisight implements embedded streaming server to package transport stream into IP protocol through Gigabit Ethernet. There are a variety of streaming protocols available especially during remote productions (REMI). On closed networks, UDP and RTSP streams can be selected for delivery. For cloud-based destinations, or when the network is congested, SRT may be more appropriate. SRT is a new open-source format that provides the reliability of RTMP, while reducing latency, for use on open networks. SRT streams can also be encrypted if security is a concern. |

Comprehensive Hardware Encoder & Decoder
Contribution Encoder GT4K-3001E offers exceptional quality at the lowest latency with securely transporting. It can encode up to four camera feeds from HD or 3G-SDI sources. This encoder and decoder pair has made producing live, muti-camera events more affordable than ever by keeping talent in-house. While GT4K-5001E is a cost competitive HEVC single channel encoder with broadcast-level. Both GT4K-3001D and GT4K-5001D are professional 10-bit hardware decoder.
Low-power and Practical Design
Different with software encoding server, Hisight GT4K series hardware encoders are powered with ARM multi-core CPU running Linux real-time O/S. And GT4K-3001 compact footprint ensures that two units will fit into a single 1RU space. The power consumption is less than 20W. Compact, robust, and low-power design is ideal for the application which is restricted with power supply and space.
