The AVerMedia H339 Hybrid Analog ATSC QAM is a TV tuner designed to receive analog television, ATSC digital broadcasts, and compatible QAM cable signals. Its driver allows Windows to recognize the tuner and communicate with supported TV-viewing or recording software. When choosing a download for Windows 11, 10, 8, or 7, check that the specific AverMedia driver package supports your operating system and system architecture.

Key Features

• Windows device recognition: Provides the hardware interface needed for Windows and compatible applications to detect and access the H339 tuner.
• Hybrid TV reception support: Enables software to use the device’s analog, ATSC, and QAM tuning capabilities, subject to signal availability and application support.
• Viewing and recording access: Allows compatible media applications to use the tuner for live television and recording. Viewing software may need to be installed separately.
• Hardware communication: Helps the operating system manage tuner commands and transfer received broadcast data to supported applications.

How to Install

1. Check your Windows version. Confirm whether you are running Windows 11, 10, 8, or 7 and whether your installation is 32-bit or 64-bit. Match these details to the driver package’s stated compatibility; an older package is not automatically suitable for a newer Windows release.

1. Download the matching driver. Choose a package specifically listing the AVerMedia H339 Hybrid Analog ATSC QAM. If the tuner came preinstalled in a computer, also check whether the computer manufacturer supplies a customized driver.

1. Prepare for installation. Close any TV-viewing or recording applications, then extract the downloaded archive if necessary. Keep the tuner connected or installed according to the computer’s hardware instructions.

1. Install the driver. Run the included setup program and follow its prompts. If no installer is provided, open Device Manager, locate the tuner or unidentified multimedia device, select Update driver, and browse to the extracted driver folder.

1. Restart and test reception. Restart Windows if prompted, then check Device Manager for warning icons. Open compatible TV software, select the H339, choose the appropriate signal source, and scan for channels.

Channel availability depends on your antenna or cable connection, local broadcasts, and software capabilities. QAM support does not guarantee access to encrypted cable channels, and installing the driver alone does not provide a TV-viewing application.

Common Issues and Fixes

• Installer fails or rolls back: Run the AVerMedia H339 setup as Administrator, temporarily disable antivirus, and install the correct 32/64-bit package. If setup still fails, update the driver manually via Device Manager using the extracted INF files.
• Device not detected: Try a different USB port, preferably USB 2.0, and avoid unpowered hubs. Check Device Manager for unknown devices or tuner entries, then scan for hardware changes. Reconnect the H339 and confirm it appears before opening TV software.
• Version conflicts with older AVerMedia or Windows Media Center tuner drivers: Uninstall existing AVerMedia TV software and driver packages, remove the old driver in Device Manager, reboot, then install the H339 driver fresh. Do not mix drivers from different H339 revisions.
