Embodiment Construction
[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0020] see figure 1 , is a schematic structural diagram of the system for automatically linking high-definition programs in the present invention. The system for automatically linking high-definition programs of the present invention includes: a remote control signal receiving unit, a microprocessor (MCU), a decoder, a memory and a display unit. The decoder is used to parse the program specific information / service information (PSI / SI, Program specific information / Service Information) from the transport stream (Transport Stream, TS stream) and transmit it to the microprocessor, so that the micropro...

The invention is suitable for the technical field of multimedia, and provides a system and method for automatically linking high-definition programs. The system for automatically linking the high-definition programs comprises a remote control signal receiving unit, a decoder, a microprocessor, a memory and a display unit, wherein the remote control signal receiving unit is used for receiving a command input by a user and used for linking the high-definition programs; the decoder is used for analyzing program special information and service information from a transmission stream to be transmitted to the microprocessor; the microprocessor is used for judging whether the current channel is a high-definition channel, feeding the high-definition channel to the display unit to inform the user of the current channel being the high-definition channel if the current channel is the high-definition channel, obtaining an event information table of the current channel to obtain a program name of the current program, obtaining current event information table information of the high-definition channel stored in the memory, comparing the event information table information of the current program with the current event information table information of the high-definition channel stored in the memory, feeding a result back to the display unit if the event information table information of the current program is consistent with the current event information table information of the high-definition channel stored in the memory for reminding a user of switching. The system and method for automatically linking the high-definition programs, provided by the invention, can ensure that the user can watch the high-definition programs at the first time without delay, thus the time of the user is saved.
Description
technical field [0001] The invention belongs to the field of multimedia technology, and in particular relates to a system and method for automatically linking high-definition programs. Background technique [0002] At present, when digital TV transmits SD signals (576I) and HD signals (above 720P) at the same time, SD signal programs and HD signal programs may be repeatedly broadcast. When a user watches a standard-definition program, he has no way of knowing whether the program is being broadcast on a high-definition channel or will be broadcast soon. And because the number of channels is large, it is very time-consuming if the user manually switches the channel to view the program, which affects viewing. Contents of the invention [0003] The purpose of the present invention is to provide a system and method based on automatically linking high-definition programs, aiming at solving the problem in the prior art that users cannot know whether the same program is being pla...
