The method of television power utilization instantly transmits the visual image of the activity. Similar to movies, televisions use the visual residual effect of the human eye to present a frame of a still image with a gradual change, forming a visually moving image. The sending end of the television system converts each fine part of the scenery into electric signals according to the brightness and the chromaticity and then transmits the electric signals in sequence. And displaying the brightness and the chroma of each micro part according to the corresponding geometric position at a receiving end to reproduce the whole original image. The progress of science and technology is an important reason for the rapid popularization of televisions.

Detailed Description

Embodiments of the accompanying sound big data signal live broadcasting system of the present invention will be described in detail with reference to the accompanying drawings.

Advertisement, as the name implies, is an advertisement that informs the general public of the society of something. The meaning of advertisement is broadly and narrowly defined. The generalized advertisement refers to an advertisement which is not used for profit, such as government announcements, inspirations, statements and the like in the aspects of political parties, religions, education, culture, municipal administration, social groups and the like. The narrow-sense advertisement refers to an advertisement for profit, and generally refers to a commercial advertisement, or economic advertisement, which is a means for business enterprises to distribute goods or services to consumers or users through advertisement media in a pay-for-sale manner. Commercial advertisements are such economic advertisements.

The word advertisement is a foreign language according to the evidence. It was first derived from latin avertere, which means attention, induction and transmission. The middle ancient english age (ca. gong 1300-1475 years) evolved into overture, whose meaning was derived as "make someone notice something" or "notify someone else of something to get someone's attention". The uk began large-scale commercial activities until the end of the 17 th century. At this time, the word advertisement is widely popular and used. The term "advertisement" used herein refers not only to an advertisement but also to a series of advertisement campaigns. The term "additive" in the concept of a stationary object is given modern meaning and is converted into "additive". The word "Chinese character" advertisement is from Japan.

At present, the voice advertisement content pushed by the television is randomly controlled or selected according to the watching experience of the audience, the former does not consider the watching habits and preferences of the current audience, the latter does not consider the watching habits and preferences of the current audience when the audience dynamically changes, and meanwhile, the voice advertisement file used by the television causes certain interference to the original voice signal of the television.

In addition, dram (dynamic Random Access memory), which is a dynamic Random Access memory, is the most common system memory. DRAM can hold data only for a short time. To retain data, DRAM uses capacitive storage, so must be refreshed (refresh) once at intervals, and if the memory cells are not refreshed, the stored information is lost. (shutdown will lose data). Dynamic RAM is also comprised of a number of basic memory cells multiplexed by row and column address pins.

The structure of the DRAM is simple and efficient, and each bit only needs one transistor and one capacitor. However, the capacitance inevitably has leakage phenomenon, which causes data error if the charge is insufficient, and therefore, the capacitance must be periodically refreshed (precharged), which is also a big feature of the DRAM. Moreover, the charging and discharging of the capacitor requires a process, and the refresh frequency cannot be raised infinitely (frequency barrier), which results in that the frequency of the DRAM can easily reach the upper limit, and even if the advanced process is supported, the effect is very small. With the advancement of technology and the desire of people to overclock, these frequency barriers are being solved slowly.
