Embodiment 1

[0040] Method embodiment 1 of the present invention can be through figure 1 Be explained

[0041] 101. Obtain the main transport stream delivered by the front-end device on the network side, where the main transport stream includes the programs corresponding to the main transport stream delivered by the front-end device on the network side and other transport streams except the main transport stream Description;

[0042]In the process of implementing step 101, the front-end device on the network side may deliver the transmission stream to the terminal device in a unicast or multicast manner. The main transmission stream is the transmission stream corresponding to the main frequency point. The corresponding main frequency point can be set to a fixed value by the network operator, and the operator will inform the user orally or in the manual. The terminal software provides The operator can write this value into the program to realize the automatic program search process; the m...

Embodiment 2

[0051] The process of this kind of program search is described below by a specific embodiment, embodiment 2 can be through the appended figure 2 Be explained

[0052] 201. The front-end device on the network side selects at least one transport stream from the transport streams to be delivered as the main transport stream, and sets program description information corresponding to multiple transport streams that need to be transmitted by the front-end device on the network side in the main transport stream, and transmitting the multiple transport streams to the terminal device through the network;

[0053] In implementation 201, the corresponding program description information in the multiple transport streams to be transmitted by the network side includes not only the program description information and program content data of the main transport stream, but also includes program description information corresponding to other transport streams;

[0054] The frequency point c...

Embodiment 3

[0154] On the basis of device embodiment 2, the acquisition unit 531 includes:

[0155] The receiving subunit 5311 is configured to receive the transmission stream issued by the front-end equipment on the network side;

[0156] The determining subunit 5312 is configured to determine the main transmission stream according to the transmission stream received by the receiving subunit from the network side.

[0157] The process of determining the main transport stream in the transport stream delivered by the determining subunit 5312 from the front-end device on the network side is illustrated by the following example:

[0158] (1) The corresponding main frequency point is set to a fixed value by the network operator, and the operator informs the user orally or written in the manual, for example: the operator prints the main frequency point information in the terminal equipment manual , or the technical service personnel of the operator will inform the user verbally when installin...

Abstract

The embodiment of the invention provides a method, a device and a system for program searching. The implementation procedure of the method is as follows: the primary transmission flow issued by the lateral front equipment of the network is acquired, the primary transmission flow comprises the program description information of programs corresponding to the primary transmission flow issued by the lateral front equipment of the network and other transmission flows besides the primary transmission flow; the program description information of programs corresponding to the primary transmission flowissued by the lateral front equipment of the network and other transmission flows besides the primary transmission flow are extracted from the primary transmission flow; and program searching is carried out according to the extracted program description information. With the technical scheme of the invention adopted, the problem of the prior art that the operation process is complex and the timeconsumption is too large because each transmission flow is required to be locked respectively in the program searching process to resolve the program description information corresponding to each transmission flow is resolved.

Description

technical field [0001] The invention relates to the technical field of digital television, in particular to a method, device and system for program search. Background technique [0002] Digital TV system is a system that can provide digital TV programs and various value-added services related to it. The digital TV system is mainly divided into three parts: program collection, production and encoding (that is, digitization); program transmission; program reception and decoding. The end that sends information in the digital TV network is called the front end, and the end where the receiver is called the terminal. A digital TV set-top box is a terminal in a digital TV network, through which TV users receive TV services and other value-added services provided by the front end. [0003] The program search service is the most basic and also the most important service provided by the set-top box for TV users. In the existing DVB (Digital Video Broadcasting, digital video broadca...
