Abstract
The invention discloses a method for playing start-up advertisements of a set top box. The existing method for playing the boot advertisements from the network server by the set top box has poor user experience and is not suitable for the set top box with small-capacity flash. After sending a standby instruction, the set-top box firstly only closes the video data output module, downloads the starting-up advertisement data from the network server to the specified DDR address, and adds the checking data and the self-defined head and tail data to the starting-up advertisement data to be used as complete advertisement data; then entering a low-power-consumption deep standby state, after the computer is started again, the main program module retrieves complete advertisement data, sequentially verifies the self-defined head data, the self-defined tail data and the verification data, and determines to play the starting advertisement or directly enters a normal starting state. The method saves and optimizes the flash storage space of the set-top box, reduces the starting waiting time and has good user experience.
Description
Technical Field
The invention belongs to the technical field of digital set-top boxes, and particularly relates to a method for playing start-up advertisements of a set-top box.
Background
At present, the set top box plays the boot advertisements mainly has two types according to the advertisement source: broadcasting the boot advertisement from the front ts stream; and playing the starting-up advertisement from the network server.
The front-end ts stream is supported by a front-end operator when the boot-up advertisement is played, and related expenses need to be paid if a common set-top box manufacturer needs to use the function, so that the number of the adopted advertisements is small. Most set-top boxes adopt a free mode, namely, a starting advertisement is played after data is downloaded from a network server, and the following two methods are mainly adopted:
1. the method has the main problems that the starting time is long, the set top box is required to download data from the network server for playing after the starting and the networking are finished, and the user experience is poor;
2. when the user uses the set-top box, the background downloads the advertisement data and stores the advertisement data in the flash of the set-top box, and the advertisement is directly played from the flash when the user starts the set-top box next time. But this method is not suitable for low-cost set-top boxes with small-capacity flash.
Disclosure of Invention
The invention aims to provide a method for playing the boot advertisements of the set top box aiming at the situation that the boot advertisements are played from a network server.
Aiming at the condition that the flash capacity of the low-cost set top box is insufficient, the data are downloaded from the network server when the set top box is in a standby state, the data are stored in a DDR (memory) designated position and are verified, the DDR is ensured not to be powered off in a standby state on hardware, the data are read from the DDR designated position and are verified when the set top box is started, and the starting advertisement is played when the verification is successful.
The method specifically comprises the following steps:
step (1) after the user finishes normal use of the set top box, a standby instruction is sent, the set top box enters a preliminary standby state, and a video data output module is closed;
step (2) the set-top box downloads the boot advertising data from the network server to the designated DDR address, the main program module calculates the verification data according to the boot advertising data, then adds the verification data and the self-defined head and tail data to the boot advertising data as complete advertising data, and stores the complete advertising data in the designated DDR address;
the structure of the complete advertisement data is: the method comprises the steps of self-defining head data, advertisement length data, verification data, starting advertisement data and self-defining tail data; the length of the custom header data is N bytes, and the length of the custom tail data is M bytes;
closing the rest modules of the set top box, and enabling the set top box to enter a low-power-consumption deep standby state;
step (4) the set-top box in a deep standby state is started after receiving a starting instruction of a user, a main program module of the set-top box is initialized, the main program module calls complete advertisement data from a specified DDR address, and a first starting initialization stage is entered;
step (5), the main program module reads the initial N bytes of data of the complete advertisement data: if the initial N bytes of data are consistent with the custom header data, executing the step (6); if not, ignoring the retrieved complete advertisement data, and executing the remaining stage of startup initialization until the normal startup state;
and (6) continuously reading the advertisement length data by the main program module, and determining the last M bytes of data of the complete advertisement data: if the last M bytes of data are consistent with the custom tail data, executing the step (7); if not, ignoring the retrieved complete advertisement data, and executing the remaining stage of startup initialization until the normal startup state;
and (7) continuously reading the verification data and the starting advertisement data by the main program module, calculating a verification value for the starting advertisement data by the main program module, and comparing the verification value with the verification data: if yes, starting to play the starting-up advertisement, and then executing the step (8); if not, neglecting the called complete advertisement data, executing the rest stage of the startup initialization until the normal startup state;
step (8) the background of the main program executes the remaining stage of the startup initialization, and simultaneously the foreground plays the startup advertisement; and after all initialization is completed and the start-up advertisement is played, entering a normal start-up state.
The main program module in the step (2) calculates the check data according to the boot advertisement data and calculates the check value in the step (7) by the same method, which is a mature prior art, such as CRC check.
The method stores the boot advertising data in the appointed DDR (memory), so that the flash storage space is saved and optimized. Meanwhile, the starting-up advertisement data is downloaded in the standby state of the set-top box and is directly played when the set-top box is started up, so that the phenomenon of starting-up pause is avoided, and the user experience is improved. Moreover, if the boot advertisement does not exist, namely the three-time verification fails, the boot initialization stage is directly entered, and the boot waiting time is reduced. The main program background executes the starting initialization residual stage and the foreground plays the starting advertisement at the same time, thereby further saving the starting waiting time.
Detailed Description
A method for playing start-up advertisement of set-top box includes:
step (1) after the user finishes normal use of the set top box, a standby instruction is sent, the set top box enters a preliminary standby state, and a video data output module is closed;
step (2) the set-top box downloads the boot advertising data from the network server to the appointed DDR address, the main program module calculates the check data through a CRC (cyclic redundancy check) method according to the boot advertising data, then adds the check data and the self-defined head and tail data to the boot advertising data to serve as complete advertising data, and stores the complete advertising data in the appointed DDR address; the structure of the complete advertisement data is: 4-byte-length custom header data, 4-byte-length advertisement length data, 4-byte-length check data, startup advertisement data and 4-byte-length custom tail data;
