    • A digital video broadcast receiver for receiving data of a plurality of services (Sl - S3) which are transmitted in bursts of data over a transmission channel is provided. The receiver comprises a rendering unit (HH) for rendering data of a selected first service (Sl) from the plurality of services (Sl - S3). The receiver furthermore comprises at least one memory unit (FM, SC) for caching at least one received burst of data associated to the selected first service (Sl) of the plurality of services (Sl - S3). The memory is furthermore used for caching at least a first part of a received burst of data of at least a second service (S2) of the plurality of services (Sl - S3). The receiver furthermore comprises an input unit (HH) for inputting a zap command to switch the rendering of the first service (Sl) to a second service (S2) of the plurality of services (Sl - S3). The rendering unit (HH) is furthermore adapted to render at least the cached first part of the received burst of data of the second service (S2) when the zap command is received by the input unit (HH).
    • 提供了一种数字视频广播接收机,用于接收通过传输信道以数据突发方式发送的多个服务(S1-S3)的数据。 接收机包括用于从多个服务(S1-S3)渲染所选择的第一服务(S1)的数据的呈现单元(HH)。 所述接收机还包括至少一个存储器单元(FM,SC),用于对与所述多个服务(S1-S3)中的所选择的第一服务(S1)相关联的至少一个接收到的数据突发进行高速缓存。 存储器还用于高速缓存多个服务(S1-S3)中的至少第二服务(S2)的所接收的数据突发的至少第一部分。 接收机还包括用于输入zap命令以将第一服务(S1)的呈现切换到多个服务(S1-S3)中的第二服务(S2)的输入单元(HH)。 再现单元(HH)还适于当输入单元(HH)接收到zap命令时,至少渲染所接收的第二服务的突发数据的第一部分(S2)。

    • An apparatus (1001), system (1000) and method (800-900) are provided for improving the de-encapsulation of sections from Multi Protocol Encapsulation (MPE) (151) and Multi Protocol Encapsulation-Forward Error Correction (MPE-FEC) (152) Sections in a DVB-H transport stream. DVB-H is a standard for broadcasting services to hand-helds. Its difference from DVB-T, C, and S that is relevant for this invention is the presence of an additional layer of Forward Error Correction (FEC). Instead of restoring only correctly received sections (151) (152) the present invention also restores fragments of sections (151) (152) by using both Transport Stream packet headers (301. i.l) and section headers (151.1). As a result, entire sections (800-900) may not be erased (which can amount to up to 4080 bytes) whenever one or more fragments are received incorrectly, but only the incorrectly received fragments (which can be each up to 184 bytes) are erased. This leads to a more efficient use of the additional layer of Forward Error Correction (FEC) information.
    • 提供了一种装置(1001),系统(1000)和方法(800-900),用于改进来自多协议封装(MPE)(151)和多协议封装前向纠错(MPE-FEC)的段的解封装, (152)DVB-H传输流中的节。 DVB-H是向手持广播服务的标准。 与本发明相关的与DVB-T,C和S的差异在于存在额外的前向纠错(FEC)层。 代替只恢复正确接收的部分(151)(152),本发明还通过使用传输流分组报头(301.I.1)和部分报头(151.1)来恢复部分(151)(151)的片段。 结果是,一旦一个或多个片段被错误地接收,但是只有不正确接收到的片段(每个可以高达184字节),则整个部分(800-900)可能不被擦除(其可以达到4080字节) 被抹去 这导致更有效地使用附加层的前向纠错(FEC)信息。
