Cheong elaborated said, " we have nothing against the dvb - t ( digital video broadcasting - terrestrial ) system proposed by the government. however, the consumer would not really enjoy low - cost set top boxes ( stbs ) or integrated digital tv receivers ( idtvs ) as we were led to believe. " what the government proposed for hong kong would be a unique variation of 8mhz dvb - t dtt standard with dolby ac - 3 sound system which is not exactly the same as that of europe nor the majority of the world s.
電視助理總經理鄭善強先生解釋：我們對政府建議的dvb - t （ digitalvideobroadcasting - terrestrial ）制式沒有特別喜惡，但消費者未必真正享受到便宜的機頂盒或解碼器及綜合數碼電視機，因為政府建議香港採用之8mhzdvb - t數碼電視制式與及ac - 3的音響系統其實與歐洲及世界其他主要地區有異。 -
To invite views from the industry and the community on the proposal to adopt dolby ac - 3 as the sound system for the dvb - t standard in hong kong ( paragraph 4. 17 )
邀請業界及社會人士就建議採用dolbyac - 3作為香港dvb - t制式的音響系統發表意見（第4 . 17段） 。 -
Second, this dissertation implements separately a mpeg - 2 video decoder and a dolby ac - 3 digital audio decoder based on software mode, and gives a audio & video synchronization algorithm based on audio - clock - benchmark in mpeg - 2 system decoder, whose feasibility and practicability have been proved by experimenting. it is an all - purpose algorithm, which can perform different decoder according to mpeg - 1 or mpeg - 2 system models, and can also be used for reference to the implementation of other multiplex stream decoders
然後，論文實現了基於軟體方式的mpeg - 2標準視頻及ac - 3格式壓縮音頻的實時解碼與回放，並依據mpeg - 2系統解碼模型實現了一種基於音頻基準時鐘的mpeg解碼器的視音頻同步演算法，實驗證明該演算法可行、實用、通用性好，對符合mpeg - 1或mpeg - 2系統標準的視音頻解碼器均具適用性。 -
For details below : 1 ) video changed from mpeg2 ps to mpeg2 ts 2 ) audio of ntsc format that can not be decoded by stb could be changed from dolby acs coding standard to mpeg1 / 2 layerll standard, and packed into mpeg2 ts format 3 ) well synchronized with audio and video by a new arithmetic " successive time stamp " this thesis made a introduction of mpeg2 standard in detail ; discussed the system timing model ; indicated the key during the transforming of video and audio ; especially explain how to deal with the pcr
2 ）針對目前機頂盒不能解碼的ntsc制式dolbyac3編碼演算法音頻信息，轉換成mpeg1 2layer編碼，並打成滿足mpeg2ts語法的信息包。 3 ）提出了能使音視頻達到良好同步的繼承性時間標簽打入演算法本文詳細介紹了mpeg2標準的語法，討論了mpeg2系統的時間模型從而指出視音頻處理中的關鍵，對pcr的處理進行了詳細的分析，提出了新的視、音頻同步演算法。
