Method and system for mobile terminal to play set-top box screen

Abstract

The invention discloses a method and a system for playing pictures of a set top box for a mobile terminal. The method comprises the following steps of connecting the mobile terminal and the set top box; extracting control parameters corresponding to various controls on a current picture of the set top box and background image data; transmitting the control parameters and the background image data to the mobile terminal; recognizing the control parameters and the background image data by using the mobile terminal; drawing corresponding controls on the mobile terminal according to the control parameters and the background image data; and combining the controls to obtain a picture which is the same with the current picture of the set top box. Relevant parameters of the various controls on the current picture of the set top box are extracted, and are transmitted to the mobile terminal; the corresponding controls are synchronously drawn on a screen according to the relevant parameters; the picture which is the same with the current picture of a set top box end are combined by the corresponding controls; the requirement on network bandwidth is low; a chip of the set top box is not required to have a coding function; a screen mapping function is fulfilled by low cost; and the method and the system for playing the pictures of the set top box for the mobile terminal are conveniently used for a user.

Description

technical field [0001] The present invention relates to the field of mobile terminals, in particular to a method and a system for playing set-top box images by a mobile terminal. Background technique [0002] The multi-screen interactive function between the current set-top box and other devices (mobile phone, PAD, etc.) is a very attractive function. In the multi-screen interactive function, the screen mapping technology (synchronously transmitting the entire screen of the set-top box to mobile phones, PADs and other devices) is a basic technology. The current screen mapping technology has the following two types: the first one is to directly transmit the current screen of the set-top box to the mobile phone through the network as a whole bitmap, but the disadvantage of this is: because the bitmap data is large, it needs to be very High network bandwidth. The second is to compress and encode the current screen of the set-top box through H.264 or other compression encoding...
