As a Sony TV owner, you may have come across the term “PCM” while navigating through your TV’s audio settings. But what exactly is PCM, and how does it impact your viewing experience? In this article, we’ll delve into the world of PCM on Sony TV, exploring its definition, benefits, and how to use it to enhance your audio experience.
What is PCM on Sony TV?
PCM stands for Pulse Code Modulation, a digital audio format that represents analog audio signals as a series of digital pulses. In the context of Sony TV, PCM refers to the TV’s ability to receive and process digital audio signals from external devices, such as Blu-ray players, game consoles, and soundbars.
PCM is a lossless audio format, meaning that it retains the original audio quality of the source material without any compression or loss of data. This results in a more accurate and detailed audio representation, making it ideal for applications where high-quality audio is essential, such as in home theaters and music systems.
How Does PCM Work on Sony TV?
When you connect an external device to your Sony TV using an HDMI cable, the device sends digital audio signals to the TV. The TV then receives these signals and decodes them using its built-in PCM decoder. The decoded audio is then sent to the TV’s speakers or external audio devices, such as soundbars or home theaters, for playback.
Sony TVs support various PCM formats, including:
- PCM 2.0: A stereo format that supports two audio channels (left and right)
- PCM 5.1: A surround sound format that supports five audio channels (left, center, right, left rear, and right rear) and a subwoofer channel
- PCM 7.1: A surround sound format that supports seven audio channels (left, center, right, left rear, right rear, left height, and right height) and a subwoofer channel

What is PCM on Sony TV and how does it work?
PCM, or Pulse Code Modulation, is a digital audio format used by Sony TVs to deliver high-quality sound. It works by converting analog audio signals into digital signals, which are then processed and transmitted to the TV’s speakers or external audio devices. This format is widely used in various audio applications, including TVs, soundbars, and home theaters.
In the context of Sony TVs, PCM is used to provide an immersive audio experience, with support for multiple audio channels and high-resolution audio formats. The TV’s audio processing system converts the digital audio signals into analog signals, which are then amplified and played through the speakers. This process ensures that the audio is clear, detailed, and free from distortion, providing an enhanced viewing experience for users.
