CMMB encrypted when the content of the two foremost bottlenecks
By zou yuhong ~ April 11th, 2009. Filed under: Hardware.
April 7, according to a message near the internal radio and television sources, the current implementation of the CA program CMMB encrypted program content required at, CMMB mobile terminal and user card is encrypted separately and treatment are indispensable. At the same time, the Broadcasting Corporation of Mobile and China Mobile at the signing of the talks, China Mobile cell phone cards are also required to meet the required on-chip and add MBMS mobile TV standard.
The lineage said that radio and video programs of the CMMB encryption bottlenecks encountered by the couple principle distributes, such as be dismayed of not properly deduce the difficult. It is construed that radio and video system at the side and add content encryption can not be achieved, the existing fees and assignments has been launched in Shanghai CMMB program content, but also spiky out that the person, CMMB mobile terminal with the user card may be encrypted is the CA affect the content of the couple assignments principle bottleneck.
It is reported that at the Olympic Broadcasting Services CMMB has been a large number of end products available, including mobile phone, MP4, GPS navigation and so on, and after the introduction of the CMMB terminal does not support the CA encryption resolution, fees and charges for receiving the content, the user needs to be replaced terminal, which the current user at the hands of a large number of CMMB terminals failure to perform its functions.
At the same time, the operation of radio and television to support the current system to start the construction is in full swing, however, receive fees for CMMB users not only to meet the terminal aspect of the CA encryption analysis at TD mobile phone SIM card or the USIM card is also required to resolve add CA to billing support systems demand charges.
The source said that at present, own a large number of cabin CMMB wireless telephone purposes, and in the homeland under the principle only permits CMMB wireless telephone to blend with the TD, it makes China Mobile mobile telephone cards can be handed out with a CA business card TDUSIM tenacity, while the 2G wireless telephone SIM business card are most expected not add, it furthermore bounds the use of a large number of cabin CMMB wireless telephone functions.
