For example: aiming at the high-definition channel of Hunan satellite television, if a user needs a PC end, a mobile phone end and a set top box end which are all in original picture code rate, implementing full platform control; to Jiangsu sanitary high definition channel, the live broadcast that the user needs the PC end is the original picture, smooth code rate, but does not open the live broadcast, and the review of PC end is smooth, need open the review, and the live broadcast of cell-phone end needs to be opened, and needs smooth high definition and super-definition, but the review need not open, to above-mentioned condition, then needs implement branch platform control.
Further, the method can also comprise the following steps: starting and stopping the service;
the system comprises a set top box, a server, a set top box and a server, wherein the service start and stop are divided into full-platform start and stop and sub-platform start and stop, wherein the start and stop of each service are independent, the start and stop of each platform service are separated, the start and stop of live broadcast service of the set top box only aim at network live broadcast, and if the.
Specifically, under a full platform, the services of all platforms of a certain channel can be started and stopped by one key, and the live broadcast, time shift and review services are independent in starting and stopping; under the sub-platform, the service is independent on the basis of platform start and stop, namely, a certain service of a certain channel is independent on the basis of platform start and stop; after closing the live service, the time-shift service of the corresponding platform is also closed because the time-shift service depends on the live service.
The method can also comprise the following steps: the global start-stop service is realized by pressing different keys to start and close all channels according to the live broadcast service, the time shift service and the review service. Specifically, the global start-stop reading material comprises sub-platform control and full-platform control, the start-stop of each service is independent, and the start-stop of different platforms under the same service is independent.
