Sony STR-AN1000 features 2 HDMI 2.1 inputs with 8K support and 4 inputs with 4K support. It has 2 outputs: 1 Main and 1 Sub/Zone2.
- 8K/60Hz and 4K/120Hz Passthrough: 2 out of 6 inputs pass up to 8K 50/60Hz and 4K 100/120Hz 4:4:4 and the rest of the inputs pass up to 4K 50/60Hz 4:4:4 video signal.
- 8K Upscaling: Sony STR-AN1000 can upscale up to 8K 50/60Hz and 4K 100/120Hz 4:4:4 from HDMI sources.
- BT.2020 Color Space: BT.2020 or Rec. 2020 is a color standard which delivers a wider color gamut compared to Rec. 709. It covers approximately 75% of the total visual spectrum while the Rec. 709 covers only 35%.
- HDCP 2.3 Copy Protection: All inputs and outputs are HDCP 2.3 compliant which is a requirement for 4K/HDR copy-protected content transmission.
- 3D Ready: Sony STR-AN1000 is able to pass 3D video through HDMI.
HDR (High Dynamic Range)
Sony STR-AN1000 supports HDR (high dynamic range) video formats such as HDR10, Dolby Vision and Hybrid Log-Gamma. High dynamic range video has greater dynamic range than standard dynamic range (SDR) video with brighter whites and deeper blacks. The result is greater contrast and more details in dark and bright areas, better color and depth.
- HDR10: HDR10 uses the wide-gamut Rec. 2020 color space. It sends static metadata via video stream to the TV which calibrates its screen brightness and color according to that. HDR10 supports 10-bit color which corresponds to 1024 shades of the primary RGB colors. It is technically limited to a maximum of 10,000 nits peak brightness, however common HDR10 contents are mastered with peak brightness from 1,000 to 4,000 nits.
- Dolby Vision: Dolby Vision is a set of technologies developed by Dolby Laboratories for high dynamic range (HDR) video. It covers content creation, distribution, and playback. Like HDR10+, it includes dynamic metadata that are used to adjust and optimize each frame of the HDR video to the consumer display's capabilities in a way specified by the content creator. Dolby Vision allows for a maximum resolution of 8K up to 12-bit color depth, maximum peak brightness of 10,000 nits and a color gamut up to Rec. 2020. It uses Dolby's proprietary dynamic metadata defined in SMPTE ST 2094-10.
- Hybrid Log-Gamma (HLG): The Hybrid Log-Gamma (HLG) is a transfer function developed mainly for HDR live video feed and over-the-air broadcasts. It is an HDR format that uses BT.2020 color primaries and a bitdepth of 10-bit. It is backward compatible with the transfer function of SDR and is designed to be better-suited for television broadcasting, where the metadata required for other HDR formats is not backward compatible with non-HDR displays. HLG defines a non-linear optical-electro transfer function, in which the lower half of the signal values use a gamma curve and the upper half of the signal values use a logarithmic curve.
Enhanced Audio Return Channel (eARC)
Audio Return Channel (ARC) feature allows the compatible TV to send audio signal to the a/v receiver through the same HDMI cable which is used to send audio and video signals to the TV. So one HDMI cable is used to transfer audio signal in both directions. New Enhanced ARC will support uncompressed audio formats such as Dolby Atmos, DTS:X, Dolby TrueHD and DTS HD Master Audio whereas the previous ARC could support only Dolby Digital, Dolby Digital Plus, DTS, DTS HD, and PCM.
Gaming Features
Sony STR-AN1000 supports Auto Low Latency Mode (ALLM) and Variable Refresh Rate (VRR) for lag-free and smooth gaming.
- Auto Low Latency Mode (ALLM): Auto Low Latency Mode enables the ideal latency setting to automatically be set allowing for smooth, lag-free and uninterrupted viewing and interactivity. When the receiver detects a gaming signal it will enter ALLM. The signal will also be sent to the TV causing it to automatically switch to a low-latency, low-lag mode for gaming. Some functions will not be available on the receiver and TV during ALLM.
- Variable Refresh Rate (VRR): VRR enables a gaming source such as a console or computer to deliver video frames as fast as it can, which in many cases is slower than the normal static refresh rate. It allows the TV to adapt to certain frame rate which reduces or eliminates lag, judder and frame tearing for more fluid and better detailed gameplay.
