Abstract
Abstract Upon implementing multi-functional TV broadcast and the like, it is desired to obtain information that pertains to a main image or that the user wants occasionally, if it does not pertain to the main image, in the form of an image as sub data with a small information size which is appended to the main image. For this purpose, MPEG4 data of sub TV information multiplexed in an MPEG2 datastream of the received and selected digital TV broadcast program is detected, and it is checked based on that detection result if MPEG4 data is included in the MPEG2 datastream. If MPEG4 data is included, an MPEG4 datastream is demultiplexed from the MPEG2 datastream, MPEG2 and MPEG4 data are respectively demultiplexed into sound, image, and system data, the demultiplexed data are decoded, and the output formats of MPEG2 image and sound data and MPEG4 scene and sound data are set.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
85 words
An image processing apparatus comprising: inputting means for inputting a data stream of MPEG 2; detecting means for detecting a data stream of MPEG 4 inserted into the data stream of MPEG 2; separating means for separating the data stream of MPEG2 and/or the data stream of MPEG 4 to a plurality of data; decoding means for decoding the separated data; and controlling means for controlling at least reproduction of image data decoded by said decoding means based on a result of said detecting means.
Claim 2
Dependent Claim
85 words
An image processing apparatus comprising: inputting means for inputting a data stream of MPEG 2; detecting means for detecting a data stream of MPEG 4 inserted into the data stream of MPEG 2; separating means for separating the data stream of MPEG2 and/or the data stream of MPEG 4 to a plurality of data; decoding means for decoding the separated data; and controlling means for controlling at least reproduction of image data decoded by said decoding means based on a result of said detecting means.
Claim 3
Dependent Claim
26 words
The apparatus according to claim 1 , wherein said inputting means inputs the data stream of MPEG 2 which is broadcasted as a digital television broadcast.
Claim 4
Dependent Claim
26 words
The apparatus according to claim 1 , wherein said inputting means inputs the data stream of MPEG 2 which is reproduced from a data storage medium.
Claim 5
Dependent Claim
37 words
The apparatus according to claim 1 , further comprising instruction inputting means for manualy inputting a instruction to be supplied to said controlling means so as to instruct a reproduction method of at least decoded image data.
Claim 6
Dependent Claim
41 words
The apparatus according to claim 1 , wherein the data stream of MPEG 4 includes sound data and system data, and said controlling means controls reproduction of the decoded image data and/or decoded sound data in accordance with decoded system data.
Claim 7
Dependent Claim
27 words
The apparatus according to claim 1 , wherein the data stream of MPEG 4 is inserted into an adaptation field of the data stream of MPEG 2.
Claim 8
Dependent Claim
26 words
The apparatus according to claim 6 , wherein the data stream of MPEG 4 is ignored by an apparatus which has no decoder for MPEG 4.
Claim 9
Dependent Claim
72 words
An image processing method comprising the steps of: inputting a data stream of MPEG 2; detecting a data stream of MPEG 4 inserted into the data stream of MPEG 2; separating the data stream of MPEG2 and/or the data stream of MPEG 4 to a plurality of data; decoding the separated data; and controlling at least reproduction of image data decoded by said decoding means based on a result of the detection.
Claim 10
Dependent Claim
72 words
An image processing method comprising the steps of: inputting a data stream of MPEG 2; detecting a data stream of MPEG 4 inserted into the data stream of MPEG 2; separating the data stream of MPEG2 and/or the data stream of MPEG 4 to a plurality of data; decoding the separated data; and controlling at least reproduction of image data decoded by said decoding means based on a result of the detection.
Claim 11
Dependent Claim
26 words
The method according to claim 8 , wherein said inputting step inputs the data stream of MPEG 2 which is broadcasted as a digital television broadcast.
Claim 12
Dependent Claim
26 words
The method according to claim 8 , wherein said inputting step inputs the data stream of MPEG 2 which is reproduced from a data storage medium.
Claim 13
Dependent Claim
36 words
The method according to claim 8 , further comprising the step of manualy inputting a instruction to be supplied to said controlling step so as to instruct a reproduction method of at least decoded image data.
Claim 14
Dependent Claim
41 words
The method according to claim 8 , wherein the data stream of MPEG 4 includes sound data and system data, and said controlling step controls reproduction of the decoded image data and/or decoded sound data in accordance with decoded system data.
Claim 15
Dependent Claim
27 words
The method according to claim 8 , wherein the data stream of MPEG 4 is inserted into an adaptation field of the data stream of MPEG 2.
Claim 16
Dependent Claim
26 words
The method according to claim 13 , wherein the data stream of MPEG 4 is ignored by an apparatus which has no decoder for MPEG 4.
Claim 17
Dependent Claim
112 words
A computer program product comprising a computer readable medium having a computer program code, for an image processing, said product comprising: input process procedure code for inputting a data stream of MPEG 2; detection process procedure code for detecting a data stream of MPEG 4 inserted into the data stream of MPEG 2; separation process procedure code for separating the data stream of MPEG2 and/or the data stream of MPEG 4 to a plurality of data; decoding process procedure code for decoding the separated data; and control process procedure code for controlling at least reproduction of image data decoded by said decoding process procedure code based on a result of the detection.
