This International Standard specifies the compression of a high-definition source format to a dual-channel packetized data stream format which is suitable for recording on disc and tape storage devices including the Type D-11 tape recorder. The specification includes a number of basic packetizing operations including the shuffling of the source data prior to compression, both to aid compression performance and to allow error concealment processing in the decoder. The standard also includes the processes required to decode the compressed Type D-11 packetized data format into a high-definition output signal. This standard supports high-definition source formats using 1 920 × 1 080 pixels and the sampling structures as specified in SMPTE 274M and RP 211 at the following picture rates: • 24/1,001/PsF; • 24/PsF; • 25/PsF; • 30/1,001/PsF; • 50/I; • 60/1,001/I where \'PsF\' indicates Progressive segmented Frame and \'I\' indicates Interlaced. The data packet format specified by this standard is used as the source data stream for the associated document which maps this Type D-11 packetized data-stream format together with AES3 data over SDTI.

This part of IEC 61834 is an extension of the SD specification (SD mode) and covers the features necessary to enable a DVCR to record and reproduce PALplus signals. While all DVCRs must have the capability of recording and/or playback in SD (SP) mode, PALplus capability is optional. For this Part 8, the data structure of a track is defined by APT = 000b which consists of four areas as described in 4.3.2 in IEC 61834-1 and AP1 = AP2 = AP3 = 000b. There are two methods for recording the PALplus signal on a DVCR: - method 1: record the partially encoded PALplus signal; - method 2: record the completely decoded PALplus signal. This part is concerned with "Method 1" (baseband helper recording) as this requires an extension to the DVCR SD specification IEC 61834-2. For "Method 2" the DVCR is equipped with a built-in PALplus decoder and the SD specification IEC 61834-2 applies unchanged.
