When it comes to high-quality entertainment, LG TVs are known for their exceptional picture and sound quality. However, if you’re new to the world of LG TVs, you might encounter some technical terms that might leave you scratching your head. One such term is PCM, which often appears as an audio format option on your LG TV. But what does PCM mean on LG TV, and how does it affect your viewing experience?
Understanding PCM: The Basics
PCM stands for Pulse Code Modulation, a digital audio encoding format used to represent analog audio signals. In simpler terms, PCM is a way to convert analog audio into digital format, allowing it to be stored, transmitted, and played back with high fidelity and accuracy.
PCM is a widely used format in various industries, including:
- Music production and distribution
- Film and television post-production
- Consumer electronics, including TVs and home theaters
- Professional audio equipment
In the context of LG TVs, PCM is an audio format option that allows your TV to process and output high-quality digital audio signals.
How PCM Works
The PCM process involves three stages: sampling, quantization, and encoding.
- Sampling: The analog audio signal is sampled at regular intervals, capturing the amplitude (or loudness) of the signal at each point. The sampling rate determines how many times per second the signal is captured.
- Quantization: The sampled signal is then converted into a digital signal, where the amplitude values are assigned a digital code. The number of bits used for quantization determines the resolution of the digital signal.
- Encoding: The quantized digital signal is then encoded into a binary format, allowing it to be stored or transmitted digitally.
PCM on LG TV: What It Means for Your Viewing Experience

- Gaming consoles: Many gaming consoles, including the PlayStation and Xbox, support PCM output for gaming audio.
PCM vs. Other Audio Formats
So, how does PCM compare to other audio formats like Dolby Digital and DTS?
- Dolby Digital: Dolby Digital is a lossy compression format, which means it discards some of the audio data to reduce file size. While it’s widely supported, it can compromise on audio quality.
- DTS: DTS is another lossy compression format, similar to Dolby Digital. While it offers better compression ratios, it can still compromise on audio quality.
- PCM vs. Dolby Atmos and DTS:X: Dolby Atmos and DTS:X are object-based audio formats that add height channels and immersive audio capabilities. While they offer a more immersive experience, they require specific hardware and content support.
PCM, on the other hand, is a lossless format that preserves the original audio data, making it the preferred choice for audiophiles and those seeking the best possible audio quality.
