HDMI 2.1-Compatible Data Transmission and Reception Subsystem

HDMI 2.1-Compatible Data Transmission and Reception Subsystem

The HDMI 2.1 specifications were defined in 2017. It has 48-Gbps bandwidth, 2.7x that of conventional HDMI 2.0, and enables the transmission of extremely large data sets, including 8K video, with very low latency while maintaining high image and sound quality. With our extensive knowledge in developing of data-transmission technologies for consumer video equipment such as recorders and 4K TVs, as well as for high-speed, serial data transmission used in large-scale servers, Socionext offers the world’s first HDMI 2.1 compatible data transmission and reception subsystem (Link/PHY).

Outline

This subsystem supports the HDMI 2.1 (High-Definition Multimedia Interface) specification. It supports video resolution of up to 4320 x 7680p and color depth of 8, 10, and 12 bits, and covers a bandwidth of 48 Gbps. While supporting L-PCM audio data and compressed audio data, the subsystem supports high bit-rate audio (up to 768 kHz) as well as sampling rates from 32 kHz to 192 kHz.

Features

  • Support for VESA DSC 1.2a
  • Support for Dynamic HDR and eARC
  • Support for game mode VRR/QMS
  • Support for HDCP2.2
  • Support for hot plug detection
