Problems solved by technology

The above three ways of changing channels all need to use a tuner to change channels, and the electronic program can only be played after the tuner is locked. Re-search the table related to the CA control word, re-configure the filter and audio and video decoder according to the frequency point corresponding to the channel to be played, and then it can be played normally. This method of changing channels prolongs the response time of channel playback, and the user experience effect is poor.

Embodiment 1

[0042] figure 1 It is a flow chart of the channel playing method provided by Embodiment 1 of the present invention, and this embodiment is applicable to the situations of channel playing or channel switching. The method can be applied to control a playing server, and executed by a channel playing device, which can be realized by software and / or hardware, for example, the channel playing device can be configured in a computer device. like figure 1 As shown, the method includes:

[0043] S110. Receive a channel play request initiated by a mobile terminal, and determine a device identifier corresponding to the channel play request according to the channel play request.

[0044] At present, the method of broadcasting program data to set-top boxes is generally as follows: the general server of broadcasting and television transmits the program data to each community through optical fiber, and the sub-servers of each community modulate the TV program through a modem and broadcast i...

Embodiment 2

[0071] figure 2 This is a flowchart of the channel playing method provided by the second embodiment of the present invention. This embodiment can be applied to the situation of receiving channel program data to be played during channel playing or channel switching. The method can be applied to one-way and / or two-way set-top boxes, and is executed by a channel playing device, which can be implemented in software and / or hardware, for example, the channel playing device can be configured in a set-top box device. like figure 2 As shown, the method includes:

[0072] S210: Receive program data broadcast by the playback control server through a preset broadcast channel.

[0073] In this embodiment, after the set-top box device initiates a channel play request to the play control server through the mobile terminal, it receives the program data broadcast by the play control server through a preset broadcast channel.

[0074] In the channel playing method provided by the embodimen...

Embodiment 3

[0080] image 3 This is a flowchart of the channel playing method provided by the third embodiment of the present invention, and this embodiment is further optimized on the basis of the second embodiment. like image 3 As shown, the method includes:

[0081]S310. Receive the frequency point allocation list broadcasted by the playback control server through the preset device information channel, and match the device identifier of the set-top box with the frequency point allocation list.

[0082] In this embodiment, after the set-top box device is started, it may first receive the frequency point allocation list broadcasted by the playback control server through the preset device information channel, and detect the activation status of the set-top box device according to the received frequency point allocation list.

[0083] Optionally, the activation status of the set-top box device may be detected by checking whether the frequency point allocation list contains frequency poi...

Abstract

The embodiment of the invention discloses a channel playing method, a device and a medium. The method comprises the following steps: receiving a channel playing request initiated by a mobile terminal,and according to the channel playing request, determining a device identifier corresponding to the channel playing request; matching the device identifier with a preset frequency point allocation list, and determining a broadcast channel corresponding to the device identifier; obtaining program data corresponding to the channel playing request, and broadcasting the program data through the broadcast channel, thereby enabling a set-top box corresponding to the device identifier to receive the program data through the broadcast channel. The method provided by the embodiment of the invention allocates fixed frequency points for the set-top box so as to play programs at different channels, thus, response time of channel playing is accelerated, and user experience is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of multimedia technology, and in particular, to a method, device and medium for playing a channel. Background technique [0002] With the popularization of digital TV, more and more users watch live programs through digital TV. The basic principle of the cable digital TV broadcasting system is to divide multiple frequency points within the fixed band range on the same cable, and fixedly broadcast programs of fixed stations on different frequency points. When a digital TV set-top box watches different channels, it needs to switch the tuner on it to the frequency point where the channel is located, re-lock, and according to the information of the frequency point received in advance, such as the sign code transmission packet (port ID, PID ), Entitled Manage Message (EMM) and other information to switch channels again. [0003] There are three ways for existing users to request channel broadcas...
