[0103] 为了进一步理解本发明的技术内容,说明如下: [0103] For a further understanding of the teachings of the present invention, as follows:

[0104] 假设一套节目的广告时间或非节目时间为Tl,节目本身时间为T2,则存储电路的存储容量只需要录制Tl时间的存储容量。 [0104] Suppose a program or ad program time period Tl, the program itself is time T2, the memory capacity of the memory circuit needs only a storage capacity of recording time Tl. 而且观看节目的延迟时间只需要Tl。 And watch the program delay time only needs Tl. 最优的状态是,当节目录制Tl时间后开始播放存储的节目,而节目录制功能仍然继续,无论非节目时间的内容是插入节目的任何时间点,都可通过快进操作跳过非节目时间。 Optimal state, when the program recording after Tl time to start playing the stored program, and program recording function continues, regardless of the content of non-program time is inserted into the program at any point, can fast-forward operation skips non-program time . 进一步分析如下: Further analysis is as follows:

[0105] 1)非节目时间为Tl集中位于该套节目的起点,则录制节目Tl时间后开始播放存储的节目时,可以立即快进操作直接跨过非节目时间的内容。 When starting a program stored in the [0105] 1) non-centrally located Tl program starting time of the program is set, the program recording time Tl, the fast forward operation immediately content directly across the non-program time.

[0106] 2)非节目时间为Tl集中位于该套节目的结尾,则录制节目Tl时间后开始播放存 After the start playback [0106] 2) non-program time Tl is centrally located in the end of the set program, the program recording memory time Tl

储的节目时,当节目结束后,可以立即快进操作直接跨过非节目时间的内容进入下一个节目。 When storing the program when the program ends, the operation can be immediately fast-forward the program directly across the non-time content into the next program.

[0107] 3)非节目时间为Tl集中位于该套节目的中间,则录制节目Tl时间后开始播放存储的节目时,当遇到非节目时间内容时,可以立即快进操作直接跨过非节目时间的内容进入节目时间的内容。 When starting a program stored in the [0107] 3) non-program time Tl concentrated in the middle of the set program, the program recording time Tl, when faced with a non-time program content, fast-forward operation directly across the non-program immediately time content into the content of the program time.

[0108] 4)非节目时间为Tl随机插入该套节目的中间的多个位置,则录制节目Tl时间后开始播放存储的节目时,当遇到非节目时间内容时,可以立即快进操作直接跨过非节目时间的内容进入节目时间的内容。 When starting a program stored in the [0108] 4) a non-random insertion program time Tl plurality of positions intermediate the sets of programs, the program recording time Tl, when faced with a non-time program content, fast-forward operation immediately directly across the content of non-program time into the content of the program time.

[0109] 如一套节目的总时间为60分钟,假定其中插入广告时间为20分钟,节目内容时间40分钟,则只需要在节目开始后,开始录制节目内容,录制20分钟后,开始播放存储的内容,在播放存储的过程中,继续存储节目后续的内容,节目数据的存储策略是,当存储内容达到存储体总容量后采用循环存储的方式,即存储地址再从起点开始。 [0109] The total time of a program is 60 minutes, which is assumed to insert ads time of 20 minutes, the contents of the program time of 40 minutes after the start of the program only needs to start recording the program content, recorded 20 minutes after the start of playing stored content, stored during playback, continue with the subsequent content stored program, program data storage policy, when the stored content reaches the total capacity of the embodiment using cyclic memory bank, i.e., memory address starting from the beginning again. 由于从起点存储的内容已经被播放,因此后续存储的内容可以覆盖前面存储的内容。 Since the starting point from the contents stored has been played, the content can be stored in the subsequent overlay content previously stored.

[0110] 本发明中所采用的存储体有多种解决方案: [0110] memory of the present invention employed in a variety of solutions:

[0111] 解决方案之一是双端口存储体,一个端口进行写入操作,另一个端口可以同时进行读出操作。 One [0111] solution is a dual port memory bank, a write port, the other port can simultaneously read operation.

[0112] 存储地址X,最低地址X0,存储容量N,最高地址为XN,当存储地址X小于存储容量的最高地址XN时,播放地址为SO = XO ;当X继续增加时,回到地址XO,即以地址XN为模值的变化。 [0112] X memory address, the lowest address X0, the storage capacity of N, XN highest address, when X is smaller than the storage capacity of the memory address of the highest address XN, playing address is SO = XO; when X continues to increase and return address XO , i.e., the address change XN modulo value. 当X循环为XO时,设置标志r = 1,S0 = X+1,这样播放起点与存储起点相差一个存储容量的延时。 When X is a cyclic XO, a flag is set r = 1, S0 = X + 1, the playback starting point so that a difference between the stored starting storage capacity of the delay. 如果在播放中采用快进,如快进Nm,对应地址前进M个,则SO = S0+M,使播放起点与存储起点相差一个存储容量-M的延时,当多次快进使SO = X时,所看内容是当时所播放的内容。 If fast-forward playback, such as fast-forward Nm, corresponding to the forward address of the M, the SO = S0 + M, so that the playback starting point and storing a storage capacity of the delay difference between the starting point of -M, when a plurality of times so that the fast forward SO = when X, are looking at content is the content was played.

[0113] 解决方案之二是快速存储体,数据写入存储体的时间加上数据读出的时间之和等于或小于采样点间隔时间,即数字化采样点间隔时间内可以完成一次写入操作和一次读出操作。 [0113] The two solutions are rapid bank, the data bank of the writing time plus the time of data read out and the time interval is less than or equal to the sampling point, i.e., the digitized samples of the interval is complete and the write operation a read-out operation.
