Frame-based audio coding with video/audio data synchronization by audio sample rate conversion

Combining two or more different edit information stream in order to improve the quality of audio information streams formed by the reproduction of some audio signal processing techniques can be used in the form of various combinations. The techniques are particularly useful in applications that combine audio information in the video information. According to a dual technique, the gain information transmitted with the audio stream, the control word are used to interpolate the reproduction sound level across the coupled portion. According to another technique, a special filter bank or a special form of TDAC transforms it is used to suppress aliasing artifacts that are on either side of the engagement portion. According to another technique, a special filter bank or crossfade window functions are used to optimize the attenuation of spectral splatter created at the bonding part. According to another technique, audio sample rates are, for example, audio information is converted according to the frame length and the frame rate can be combined with the video information. According to another technique, across the union of a suitable synchronization is maintained so that the audio blocks are dynamically arranged. Silye of NTSC video and 48 kHz audio to be combined are described.
