According to Thomson, the partners demonstrated he first implementation of a complete encoding-decoding chain for HD and Ultra HD broadcast based on the new Dolby AC-4 audio codec at the Dolby ATSC 3.0 showcase event in Atlanta.
Thomson contributed its ViBE VS7000 multi-screen encoding/transcoding platform, featuring HEVC UHD video delivery integrating with the Dolby AC-4 encoder. The content was played back on a set-top box based on the ST Ultra HD STiH418 chipset.
“The emerging Dolby AC-4 codec is rapidly becoming a new standard for next-generation audio encoding; in fact, it’s known as the audio counterpart to the emerging HEVC video codec. Working together, AC-4 and HEVC provide a coherent and efficient solution to the challenge of transporting Ultra HD content on television networks,” said Eric Gallier, vice president of marketing, Thomson Video Networks.
“As one of the first-ever worldwide implementations of HEVC, our ViBE VS7000 is the ideal platform with which to demonstrate the groundbreaking capabilities of Dolby AC-4 and ST’s SoC for next-generation Ultra HD video offerings on any type of device and over any type of network.”
