Problems solved by technology

However, the first disadvantage of synchronous frequency networks is that the receiver cannot cope with Doppler shift when the signal is affected by severe multipath that occurs in synchronous frequency networks
The second disadvantage is that the operator cannot change the content as it may be expected to provide location-dependent services
Larger latencies degrade overall system performance from a user perspective

Embodiment Construction

[0035] The most typical division of the DVB-H receiver system 1 is schematically shown in FIG. 1 in the typical form of a cellular phone. The receiver component 2 is mainly composed of a tuner 3 and a DVB-H baseband receiver 4. The DVB-H baseband receiver 4 is connected to the host component 5 of the cellular phone via a data interconnection 7. The host component 5 includes a host processor 6 (also It may be an application engine), and the data interconnection 7 includes one of the typical interfaces (SPI or SDIO) in the application field. The display 14 and the speaker 15 are connected to the host assembly 5. The receiver component 2 is responsible for receiving the air signal via the antenna 13, recovering the MPEG transport stream, and decapsulating the IP packet. The IP packet is transferred to the host component 5 via the data interconnect 7. The IP-encapsulated audio / video content is forwarded to the media player unit 8 running on the host processor 6 for decompression,...

Abstract

The invention relates to a method for controlling a receiver system (1), in particular for wireless IP datacast networks, the receiver system (1) comprising a receiver component (2) with an antenna (13), and a host component (5) with a player unit (8) having a buffer (10), the method comprising the following steps: -within said receiver component (2), detecting a time of a burst packet coming in via said antenna (13); -communicating information about said detection from said receiver component (2) to said host component (5); -transferring data of said burst packet from said receiver component (2) to said host component (5) via a data interconnection (7); and -within said host component (5), adjusting a playing speed of said player unit (8) according to said information.

Description

technical field [0001] The present invention relates to a method of controlling a receiver system and a receiver system particularly suitable for a wireless IP (Internet Protocol) data broadcasting network, said receiver system comprising: a receiver assembly with an antenna and a host assembly with a player, said The player has a buffer. Background technique [0002] The invention is particularly applicable to Digital Video Broadcasting for Handheld Devices (hereinafter referred to as DVB-H). DVB-H is a standard for bringing digital television content to mobile handsets. DVB-H is based on the Digital Terrestrial Broadcasting Television (hereinafter referred to as DVB-T) standard and its IP data broadcasting mode. The benefit for mobile devices comes from the introduction of time slicing, which allows a receiver to only listen to the DVB-T stream to receive the data it is interested in. Time slicing is achieved by intelligently combining MPEG ("Moving Picture Experts Grou...
