Embodiment Construction

[0011] exist figure 1 A broadcast stream is denoted by reference numeral 10 in , which includes 5 channels. Stream 10 is broadcast by broadcast server 20 to a set of mobile devices 30 .

[0012] In this embodiment, each mobile device 30 includes: a mobile handset; a Subscriber Identity Module (SIM) 35 that is detachably inserted into the mobile handset and carries a (non - represented) the secret credential of the mobile telephone communication network; and a mass memory card 36 of flash memory type, which is also inserted in the mobile handset. The mass memory card 36 is preferably a secure card, such as an SD card - Secure Digital.

[0013] Mobile device 30 has the capability to present any of the five channels carried in stream 10 .

[0014] Each of the five channels carries a digital signal decoded by the mobile device 30 . For this purpose, the mobile device comprises a memory unit which stores a secret key and implements software for deciphering the received stream 1...

Abstract

The invention relates to a method for rendering content on a mobile equipment, comprising rendering a content from a broadcasted stream (10), the method further comprising the step which consists in providing a mass memory in the mobile equipment and storing content from the broadcasted stream into the mass memory characterized in that it comprises the step which consists in a remote broadcaster entity commanding (11, 12, 13, 15) the mobile equipment into storing the content from the broadcasted stream into the mass memory.

Description

technical field [0001] The present invention relates to mobile TV, ie broadcasting of TV programs to mobile devices. Background technique [0002] Recently, there has been a rapid development of mobile TV, which provides users of third generation mobile phones to receive TV programs on their mobile phones. Mobile TV is not limited to broadcasting TV programs to mobile phones. There is an approach to rendering such broadcast programs onto a radio device the size of a cell phone, but which is not capable of performing full-duplex voice services, ie, cannot be used for mobile telephony. [0003] When compared to cable TV or TV over cable Internet, mobile TV suffers from a limited bandwidth of the transmission band, which in practice means that a limited number of parallel broadcast programs are available, i.e. the user's choice of programs at a given moment is limited , typically ten programs on ten corresponding channels. [0004] Operators, and more generally any mobile TV...
