Problems solved by technology
The problems existing in the existing storage and playback equipment are: 1) because the storage and playback cannot work at the same time, the program being played will be missed during playback; 2) when the program is stored, it is necessary to record all the programs including the advertisement information in order to watch all the programs The content requires a lot of storage capacity, and its storage capacity is the sum of the storage capacity required for non-program time and the storage capacity required for program time, which increases the cost of storage and playback equipment, and the delay time for watching programs is too long, that is, when the delay time broadcast time of the entire program

Embodiment Construction
[0146] The core point of the present invention is to store the multimedia broadcast signal first, then read and play, and enable the subsequent multimedia broadcast signal to continue to be stored during playback, thereby reducing the storage capacity and filtering out unnecessary The content needed to improve the receiving experience of the recipient.
[0147] Specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0148] figure 1 It is a schematic diagram of the working principle of the first solution of the storage delay circuit for processing analog multimedia signals in the present invention. The analog multimedia broadcasting signal sends the wired or wireless radio frequency signal to the tuning receiving circuit 101 through the multimedia signal input circuit. The signal is sent to a storage delay circuit 100 for processing. The storage delay circuit 100 includes a multimedia signal digitization c...

The invention provides a method for realizing content filtering of simulating multimedia broadcasting, which is used for processing simulating multimedia broadcasting signals. The method is characterized by comprising the following steps of: receiving the simulating multimedia broadcasting signals by a tuning circuit; sampling and digitalizing the simulating multimedia broadcasting signals into multimedia data; storing the multimedia data in a storage; and reading the data from the storage after delaying a period of time, synthesizing the data into multimedia signals, and then outputting the multimedia signals, continually sampling and digitalizing the simulating multimedia broadcasting signals into multimedia data while reading data from the storage and storing the multimedia data in the storage. The storage can at least complete one-time data storage function and one-time reading function in the time interval for sampling and digitalizing. The invention realizes that a receiver filters unneeded content according to own preference under the demand of minimum delay time and minimum storage capacity so as to improve receiving experience of the receiver.
Description
technical field [0001] The invention relates to a method for realizing filtering of analog multimedia broadcasting content, in particular to a method for realizing filtering of multimedia broadcasting content by adopting methods of storing delayed playing and simultaneously storing and playing simultaneously. Background technique [0002] With the development of electronic technology and information technology, broadcast signals have developed from the original analog wireless broadcast signals to analog cable broadcast signals, analog satellite broadcast signals, digital wireless broadcast signals, digital cable broadcast signals, and digital satellite broadcast signals. The broadcast content includes multimedia broadcast content composed of audio, video, data and other information, so that people can receive multimedia broadcast content through multiple channels. [0003] On the other hand, for their own development, broadcast operators usually insert advertising informati...
