Abstract:
PROBLEM TO BE SOLVED: To realize a picture display method capable of reducing animation pseudo-contours sharply while maintaining all possible gradation property even when it is a part where greater animation pseudo-contours are generated in a picture display method which performs gradation display by the subfield method. SOLUTION: In this picture display method, when pixels are non-object pixels, a picture is displayed by converting gradation values of pixels into displayable gradation values and when the pixels are object pixels, a picture is displayed by converting the gradation values into a first gradation value which is the average value of n (n is an integer of 2 or more) pieces of gradation values which are selected from among displayable gradation values and by performing a first diffusion treatment which averages the first gradation value spatially and/or temporally using the n pieces of gradation values.

Abstract:
PROBLEM TO BE SOLVED: To provide a digital broadcast system capable of efficiently transferring data. SOLUTION: A data processing local device 21 in a CATV station 20 in the digital broadcast system merges TCP data of a plurality of subscriber replay data whose IP destination addresses are mutually the same and whose TCP port numbers are identical to each other, contains the merged TCP data in a TCP/IP segment datagram having the same IP destination address and TCP port number as the IP destination address and TCP port number of the plurality of subscriber reply data, and transmits the TCP/IP segment datagram to a broadcasting station 10 via the Internet 50.
