Transcoding enables the conversion of high-quality streams with high bitrates and resolutions into low-bitrate, low-resolution streams. However, directly reducing the bitrate from high to low can lead to decreased image quality and ultimately negatively affect the user’s viewing experience.
To solve this problem, CDNetworks has introduced the Low Bandwidth High Definition(LBHD) Transcoding. This feature automatically adjusts the optimal bitrate based on the video content and enhances the image using CDNetworks’ proprietary encoding technology. By fine-tuning the bitrate reduction without compromising the original image quality, LBHD transocoding significantly reduces bandwidth costs for video service providers while providing the optimal viewing experience for users.
By leveraging advanced technologies such as Scene Recognition, Lossless Bitrate Reduction, and Image Quality Rebuild, CDNetworks has been able to effectively decrease bitrate while maintaining or even enhancing image quality as appropriate.
During the transcoding process, LBHD conducts a detailed analysis of the video content prior to re-encoding. Based on the specific characteristics and scenes of the video stream, it optimizes encoding parameters to the greatest possible extent, achieving maximum bitrate reduction without compromising picture quality.
To enhance the visual experience for viewers, CDNetworks has optimized its encoders in the following ways:
By repairing the damaged parts caused by camera shake, transcoding distortion, or other factors in the video stream, the customer viewing experience can be enhanced.
It should be noted that the LBHD stream has a different URL format from the regular stream. For example:
Regular stream: http://www.test.com/live/playlist.m3u8
LBHD stream: http://www.test.com/live/playlist_lbhd.m3u8
