Audio and video digital recording, also referred as audio and video codecs, can be uncompressed, lossless compressed, or lossy compressed depending on the desired quality and use cases. ![]() Image 1: Three parts of the image that were comparedĪ comparison was made of the image quality for parts A, B, and C. The three parts (Ⓐ, Ⓑ, and Ⓒ) of Image 1 on the under were compared to assess the image quality obtained with 4:2:2 chroma format and that obtained with 4:2:0 chroma format for three successive encoding/decoding operations. The following section compares the image quality of AVC/H.264 High Profile, which is incompatible with the 4:2:2 chroma format, and that of High 4:2:2 Profile, which is compatible with this format. To limit degradation in the quality of the video images delivered to viewers, it is essential that any image quality degradation that may be caused by the use of cascaded codec systems be minimized.įigure 1: Example process for the delivery of live images to viewers Comparison of image quality of AVC/H.264 High Profile and High 4:2:2 Profile in cascaded codec connection If your PowerPoint presentation cannot play video or audio embedded on it and shows 'Codec Available' error, you can fix the problem with these methods. ![]() ![]() For the live broadcasting of sports or other events from the venue itself, video codec systems are generally connected in cascade (for multiple encoding and decoding), as shown in Figure 1 below, to deliver images recorded by the cameras to TV viewers.
