摘要： A telecommunications system is disclosed which includes a content server 30 for distributing content and a device 1 for receiving this content during a communication session and for reproducing this content. The device 1 is operable during the communication session to transmit to the content server an indication of a quality of the received content required by the device 1. The content server 30, in response to this indication, adjusts the content that is transmitted thereafter to the device 1. For example, this indication of a quality could be an indication that only audio or only video content should be transmitted to the terminal, or an indication of the quality with which video and/audio content should be transmitted to the terminal. Indication may be generated by the device 1 automatically in response to the conditions in which the device 1 is being used, or may be manually selected by the user of the device 1.

摘要： A catalyst suitable for the dehydrogenation and hydrogenation of hydrocarbons comprises at least one first metal and at least one second metal bound to a support material. The at least one first metal comprises at least one transition metal, suitably a platinum group metal. The support material is provided with an overlayer such that acidic sites on the support material are substantially blocked. In a preferred embodiment the catalyst is also substantially chloride free. Method of preparing catalyst are also disclosed.
