Media technology and services provider MediaKind is working with New Digital Technology Group’s (NDT) to enable the delivery of high-quality recorded 4K content for BTV’s winter sporting events channel and the upcoming Winter Olympics.
MediaKind provided a range of its leading encoding and decoding solutions, supporting Beijing in enabling the first provincial level 4K Ultra High Definition (UHD) channel broadcast on satellite in China. The entire project was carried out and put on-air in less than three months.
The MediaKind solution includes the AVP 4000 HEVC encoder, MK RX1 multi-codec multi-service professional decoder, and AVP 1000 Stream Processor. This stable, hardware-based, high-quality, and low latency encoding/decoding 4K solution enables BTV to deliver the best possible experience to its subscribers across China.
The MediaKind solution is integrated into NDT’s iSwiftMedia, which is an end-to-end multi-vendor NMS (Network Management System), OSS (Operational Support System) and orchestration software solutions for the broadcast, satellite, cable, telco and mobile industry.
As a core module of the latter, the (NDT) software-defined network management (SDNM), incorporating the video and audio broadcasting channel, coding transmission, and 4K master control. SDNM management software adopts SDN architecture and is compatible with SDI over IP non-compressed and transport steam over IP (TSoIP) compressed signal streams.
Using IP to power UHD smoothly
Wang Tong, President, NDT, said: “The integration of our technologies enabled our IP-baseband hybrid architecture to power the broadcasting master control, ensuring BTV’s exciting 4K UHD channel went online smoothly and onto the screens of thousands of households nationwide.”
The MediaKind solution adopts the HEVC coding compression standard to direct content across Gehua's large-scale network, while the AVS2 coding compression standard is adopted to facilitate satellite distribution.
The last stage output enables stream fault detection and automatic switching. The system link supports embedded audio and Dolby related standards to meet the application requirements of Dolby Digital (AC-3), Dolby Digital Plus (E-AC3).
The whole system is equipped to continue running satellite channels' broadcast demand during emergency maintenance required. The satellite receiving system can receive UHD signals with special encryption methods at home and abroad.
