In our former work, the novel intra prediction scheme based on preserving frequency component of neighboring blocks is proposed as an extension approach for H.264 standard coding. However, the block basis coding syntax especially for newly introduced control parameters has not been specified in our previous work. In order to finalize our coding scheme, a prediction scheme as a part of decoding process is proposed to determine above control parameters without any side information.

We have been studying a technology for the transmission of additional information for data broadcasting, such as regional information, using terrestrial digital broadcasting services assisted with the Intelligent Transport System (ITS). This information is transmitted via the Dedicated Short-Range Communication (DSRC), which is a scheme for road-to-vehicle communication. This paper describes improvements to the DSRC communication procedure to make it feasible to receive more information securely during the short time in which a vehicle passes under a DSRC road-side antenna.

The information embedding based on the embedding using the lifting principle (LPE) that a quality embedding image can be made by performing high, order embedding [5]. In our previous work [3]. the Linking Number (LN) to the plane in the RGB color space of the watermark image by LPE was defined [2]. And it was shown that this LN could serve as an index for alteration detection of a watermark image. In this paper, the following things are showed by the experiment using the standard image, i) M dimension color space has 2M over three dimensional plane structure, ii) LN to this plane is used as an index for alteration detection of an embedding image, iii) LN for this detection is obtained by choosing suitably the three dimensional space in M dimension space, iv) This selection can have the application possibility to verification that can adjust the degree of detection according to quality of image.
