SAPEC, a Spanish Company specializing in professional solutions for audio and video signal transmission, is coming to Las Vegas once again. For NAB 2015, SAPEC (stand SU-11.413), will bring along great innovations offering complete coverage to all broadcasters and telcos throughout the American continent, largely through its offices in Mexico and Colombia, and also through its distributors spread over the whole continent.
HEVC Encoders and Decoders and 4K Experience
SAPEC’s R&D&i continues to work on its successful real-time HEVC Encoders and Decoders with ITU-H.265 implementation, which will be fully operational at the 2015 NAB, stand SU-11.413.
Featuring among the principal characteristics of the new versions of these real-time HEVC encoders and decoders, with support for interlaced SD and HD signals, will be 10 bit (Main10@L4) video encoding and MPEG/AAC/Dolby Digital/Dolby Digital Plus (with up to 8 stereos) audio encoding.
The outputs are DVB-ASI and/or Ethernet 100/1000 under the SMPTE 2022-2 standard, and allow for a reduction in bitrate without any change in video quality.
The system is a 1RU Chassis system with redundant power supply engineered to the highest standards and designed with large worldwide broadcasters and telcos in mind.
Optimal transmission for optimal resolution
SAPEC’s R&D&I team has continued to build on its 4K encoding experience throughout the last year, one example of this being its participation in the latest Mobile World Congress (MWC), held in Barcelona from March 2 to 5, 2015, as part of the telecommunications infrastructure operator Abertis Group project. Abertis had on display in its exhibition area – Congress Square, Spain Pavilion – the latest advances in the DTTV field, with demonstrations of UHD diffusion over DVB-T2 and Hbbtv.
For the demonstration of UHD diffusion over DVB-T2, SAPEC, as in the three previous editions of MWC, was responsible for the content compression, using the HEVC (ITU-H.265) video coding standard for the second year in a row.
At stand number SU-11.413 of the Las Vegas Convention Center we will be able to see this HEVC coding in 4K (4Kp50) at 10bit for 4:2:0.
The New Sivac One
The new Sivac One modular codification system will be one of SAPEC’s great revelations at the 2015 NAB. This system is capable of including up to three encoders in just 1RU (allowing hot insertion), and is equipped with a redundant power supply. The new Sivac One features MPEG-2 y H.264 encoding with 4:2:2 and 4:2:0 profiles and 8- & 10-bit support, with HD-SDI inputs (1 video/16 audios), audio inputs (4 AES-EBU), generation of up to 8 PMTs, 2 ASI outputs and 2 IP (SMPTE 2022).
SAPEC will also present its range of products aimed at offering solutions for the transmission of signals via satellite. These products consume less energy, take up less space and cost less. The GREDOS systems for satellite applications include a video coder and DVB-S/S2 satellite modulator in just 1RU. All of the encoding algorithms are of the same standard as those of the Altum II family, with the addition of a DVB-S/S2 satellite modulator.
The modulator supports the DVB-S, DVB-S2 y DSNG standards, as well as Carrier ID, required in DVB-S2, with a Roll-off factor of up to 0.05 and modulation up to 32-APSK, with the innovation of being software-upgradable to the new DVB-S2X y Multistream capabilities.
As for the encoder, this fourth-generation device supports HDTV (and/or SDTV) as well as MPEG-2 and/or H.264, including 4:2:2 profiles, and features simultaneous ASI, Ethernet y L-Band outputs.
The Receiver/Decoders (IRDs) feature L-Band, Ethernet and ASI inputs, supporting MPEG-2 and/or H.264, including 4:2:2 profiles, and allow for redundancy management between inputs, as well as signal re-transmission by Ethernet and/or ASI.
The Fourth-Generation ALTUM II
The ALTUM II family are now more energy-efficient, and offer greater functionality at a lower cost. ALTUM II are MPEG-2 / H.264 encoders and decoders with 4:2:2 profiles supporting HD and SD, and feature the innovation of PSI / EPG insertion (from Triveni Digital).
They include two ASI interfaces and two IP, with input/output interfaces over IP for networks without QoS, as well as featuring a redundant AC/DC power supply. They now include a higher-capacity display allowing for the configuration of all encoder parameters from the front panel.
These systems have greatly improved compression algorithms, using a lower bit rate for the same image quality. They reduce the overall video to video latency by 20%, are more environmentally-friendly due to their improvement in energy-efficiency (reducing consumption by around 30%), and feature N+1 redundancy without external agents including the option of retransmitting the TSoIP received by the decoder to another destination.
Finally, we will take a look at our multi-screen systems. The Qview 3G-SDI Multiviewers, developed and manufactured by DQE, will be on display at the SAPEC stand in Las Vegas (stand SU-11.413). These are compact 1RU and ½ rack systems with 3G / HD / SD-SDI, optical and HDMI inputs, and HDMI & HD-SDI outputs, and now have the capacity for up to 8 auto-sensing inputs.
This low-latency QView Multiviewer is a multi-screen processing system based on autonomous units which are very user-friendly, ideal for high-quality signal monitoring in studios, mobile units and on site. It has up to 10 memory presets available, VU meters, UMD, Tally, Time Code, clocks, and up to 32 inputs to one output, through cascade coupling.
