摘要： PROBLEM TO BE SOLVED: To provide a method of the use of a non-initialized buffer capable of being simplified.
SOLUTION: This is demonstrated with an example timing scenario. In this example, again the encoder generates a random access point after the fifth picture. In this example, (as is often the case in such scenarios) to achieve the best possible picture quality, the first picture after the random access point should be a relatively large picture (because of intra coding). With this revised model, as there is no constraint to empty the buffer at this point, a relatively large amount of data can be allocated to the first picture after the random access point, instead of the fifth picture.

摘要： PROBLEM TO BE SOLVED: To provide a simplified buffer model with a method based on non-zero buffer fullness for a buffer model.SOLUTION: An encoder side sends to a decoder side a bit stream and delay time information. The delay time information represents when image data is supplied to a virtual decoding buffer which stores the image data with the bit stream decoded, which is set in accordance with a virtual buffer model based on non-zero start time.

摘要： PROBLEM TO BE SOLVED: To provide a method using a non-initialized buffer easy to simplify.
SOLUTION: A timing scenario is described using an example. An encoder in the example generates a random access point after a fifth picture. To attain the best picture quality in a possible range in the example (often occurring in such scenario)a first picture after the random access point must be a comparatively a large picture (to execute an intra-coding). By using the modified model, there is no restriction that the buffer is made empty at this point and hence a comparatively large data quantity may be allotted to the first picture after the random access point instead of the fifth picture.

摘要： PROBLEM TO BE SOLVED: To easily detect the head of data and the position of a scramble control flag when recording data of MPEG 2-PS in conformity with the specification of a CD-ROM, and to carry out the stuffing and padding of a small number of bits.
SOLUTION: For recording encoded data on a record medium divided into sectors and accessible sector by sector by dividing the data into predetermined lengths, adding a header to create a packet, adding another header, when stuffing is necessary, stuffing data are inserted into the last portion of the data area of the packet. Thereby, the length of a pack header can be fixed. Since it is unnecessary to provide a padding packet, there occurs no encryption of a PES header or no problem un encryption.

摘要： PROBLEM TO BE SOLVED: To shorten start-up delay.
SOLUTION: At time t
7 , DTSV indicating the decode starting time (t
8 ) of a video decoder is inputted and video data is written in a video code buffer at a maximum transfer rate. During that interval, SCR indicating the current time is monitored and a decision is made whether the SCR is equal to the DTSV(t
8 ) or not. When the SCR becomes equal to the DTSV(t
8 ) (at the time t
8 ), decoding of video data is started thus shortening start-up delay.

摘要： PROBLEM TO BE SOLVED: To provide a method using a non-initialized buffer that can be simplified.
SOLUTION: A timing scenario is explained using an example. In the example, an encoder generates again a random access point after a fifth picture. In the example, in order to achieve picture quality as high as possible (frequently in such a scenario), a first picture after the random access point should be a relatively large picture (for performing intra-encoding). By using such a modification model, since there is no limitation where a buffer is made empty at the point, a relatively large data amount can be allocated to the first picture after the random access point, in place of the fifth picture.

解决方案：使用示例说明时序情景。在该示例中，编码器在第五图像之后再次生成随机接入点。在该示例中，为了尽可能高地实现图像质量（频繁地在这种情况下），随机接入点之后的第一图像应该是相对较大的图像（用于执行帧内编码）。通过使用这样的修改模型，由于在该点处没有限制使缓冲器为空，所以可以在随机接入点之后的第一图像中分配相对大的数据量来代替第五图像。版权所有（C）2009，JPO＆INPIT
