The present invention discloses a signal display output method, apparatus and system, which pertain to the field of computer technologies. The method includes: receiving, by a TV box expansion device, a radio television signal by using a radio frequency port; performing, by the TV box expansion device, demodulation processing on the radio television signal to obtain a to-be-decoded digital signal; and sending, by the TV box expansion device, the to-be-decoded digital signal to an IP TV box, so that the IP TV box performs decoding processing on the to-be-decoded digital signal to obtain the decoded digital signal for display output. Use flexibility of the IP TV box can be improved by using the present invention.

Die Patentanmeldung betrifft ein TV-Empfangsteil mit einem steuerbaren Eingangsfilter (FI) zum Unterdrücken von Störleistung in einem Eingangskreis (I HF ) einer HF-Abstimmeinheit (TUN) verursacht durch Sendespektren von terrestrisch empfangenen Funkdiensten und löst ein Problem, welches dadurch entsteht, dass in wenigstens einem Frequenzunterband (beispielsweise von 791 MHz bis 821 MHz) schrittweise ein Betrieb von weiteren Funkdienstarten über die bisherige Nutzung für terrestrische Fernsehfunkdienste oder Kabelfernsehen hinaus zugelassen ist. Gemäß der Aufgabe sind die im TV-Empfangsteil enthaltenen Eingangsfilter (FI) an den sich ändernden Status einer regionalbedingten aktuellen Empfangssituation anzupassen. Das TV-Empfangsteil enthält eine Steuereinrichtung (CTRL) und das Eingangsfilter (FI) zum frequenzselektiven Unterdrücken von Sendeleistung aus Sendespektren in einem Frequenzunterband. Das TV-Empfangsteil nutzt Analyseroutinen, welche die folgenden Merkmale aufweisen: Die Steuereinrichtung führt mit der Abstimmeinheit (TUN) Sendersuchläufe im entsprechenden Frequenzunterband zum Auffinden von Sendespektren aus. Erkennungsmittel für eine Dienstarterkennung bestimmen im Frequenzunterband die aktuelle Empfangssituation in der Empfangsregion anhand eines für selektierte Sendespektren benutzten Übertragungsstandards. Die Steuereinrichtung steuert das Eingangsfilter abhängig von der aktuellen Empfangssituation alternativ in Einstellzustände, die einen Durchlasszustand beziehungsweise einen frequenzselektiven Sperrzustand umfassen.
摘要:
A reception apparatus for receiving an OFDM signal transmitting data in burst for each service by time division. When services for mobile terminal reception and services for fixed terminals are transmitted as the provided services, null packets may be transmitted before and after the slot carrying the mobile receiver service so that the fixed reception service and the mobile reception services are not mixed. The mobile receiver runs the FFT and subsequent equalization and error correction processes only for the specific slot containing the specific service.

Disclosed are a display apparatus, system and control method , the display apparatus including a communicating unit which performs a communication with an external tuner, and receives an intermediate frequency (IF) signal from the external tuner; an IF signal processing unit which processes th e IF signal received in the communicating unit; and a control unit which controls the IF signal processing unit to process the received IF signal to be a signal displayable on a display unit if receiving the IF signal from the external tuner.
摘要:
A method of operating a multi-stream reception scheme, such as DOCSIS (Data Over Cable Service Interface Specifications), comprising at least two receivers (10, 12, 14) having respective voltage controlled oscillators (16), the method including monitoring a change in local oscillator frequency in a selected one of the at least two streams and, if the frequency distance between the local oscillator frequencies is below a value likely to cause pulling or coupling between the voltage controlled oscillators of the at least two receivers, resetting the frequency planning of the selected one of the at least two streams to maximise the frequency distance of the voltage controlled oscillator of the selected stream with the voltage controlled oscillators of the or the other streams.
