<p>PURPOSE:To suppress an encoding delay at several tens of milliseconds by thinning the output of a pre-filter, which eliminates noise or controls a band for a digital moving picture input at plural channels, in units of a frame, generating and encoding the multiplexed moving picture, and separating the output to plural pieces again. CONSTITUTION:Pre-filters 4, 5 and 6 to eliminate the noise and to control the band for the digital moving picture input at the plural channels, and a multiplexing circuit 7 to generate one multiplexed moving picture from the plural pre-filter outputs by thinning the pre-filter output in units of a field or the frame, and multiplexing it are provided. Further, the output of an encoding circuit 8 to encode the output of the multiplexing circuit 7 is separated to the plural pieces again. Thus, a transmitting buffer to even generated information is replaced with a packet assembly circuit, the generated information becomes a short packet, and transferred in several tens of milliseconds.</p> |
