Definitions of variable bit rate:
- provides a specified throughput capacity but data is not sent evenly. This is a popular choice for voice and videoconferencing data.

- Variable Bit Rate adjusts the bit rate depending on the sound. For example, if there is silence in a song, the bit rate would decrease and if there is a full symphonic sound the bit rate would increase. VBR offers a higher sound quality at a smaller file size.

- Definition: An ATM Forum defined service category which supports variable bit rate data traffic with average and peak traffic parameters.

- The flow of data being processed on a DVD can be variable, depending on the complexity of the information being processed. Fast moving, dynamic scenes require a high data rate, while a static (non-moving) image requires a lower data rate.

- Information that is represented in a digital form by clusters of bits (rather than a constant stream of bits) is said to have a variable bit rate. Most data applications generate VBR traffic. Compare with constant bit rate.

- A method of compressing and encoding audio at a bit rate optimized for each section, or "frame," of sound, depending on the part's complexity. This allows for high fidelity, while helping to keep file size down.

- Many newer audio and video codecs employ a technology known as variable bit rate encoding, which allows resulting files to look and sound better, while still retaining a compressed, convenient file size. Essentially, VBR encoding assigns more bits to complexly detailed passages in the original source, and fewer bits to the simpler passages. ...

- (VBR) - A data transmission that can be represented by an irregular grouping of bits or cell payloads followed by unused bits or cell payloads.

- Bit rate varies with time during the decoding of a compressed bitstream. One example is MPEG-2 for DVD-Video where bit rate changes according to compression requirements to keep the average bit rate low. VBR encoding offers better quality than constant bit rate (CBR) at lower data rates.

- A quality of service, for ATM networks, with two subcategories. First is Variable Bit Rate - Real Time (VBR-RT) - for timing sensitive connections such as video or voice. Second is Variable Bit Rate - NonReal Time (VBR-NRT_ - used for bursty or other non-time-sensitive transmissions. Both types guarantee minimum delay and cell loss.

- The term variable bit rate (VBR) is a term in telecommunications Quality of Service. Compare with constant bit rate.
